Abstract Sleeve gastrectomy (SG) is currently considered as a primary bariatric surgery. This is because of its relative simplicity and satisfactory results. As observed with other bariatric procedures, surgeons are confronted with insufficient weight loss or weight regain, insufficient resolution of metabolic disorders, and intractable severe reflux. A retrospective analysis of conversion from SG to Roux-en-Y gastric bypass (RYGBP) was performed to assess weight loss, diabetes resolution, and relief of reflux symptoms.
*** In ONLY 2 yrs!! The mean interval between the two procedures was
almost 24 months.
*** Eighteen patients underwent conversion from SG to RYGBP for
insufficient weight loss (n = 9),
severe reflux (n = 6), and persistence of type 2 diabetes mellitus
(T2DM) (n = 3).
Imagine the results in 10 years!
The median follow-up was 15.5 months. Weight loss was significantly improved with a mean percentage of excess of body mass index loss at 64.6 % after conversion versus 47.1 % before conversion. All reflux symptoms were immediately relieved without any medication at the end of the follow-up. The three patients who had an operation for persistence of T2DM are now free of medication. Only one postoperative complication was observed as a small bowel injury, which was treated surgically. Conversion from SG to RYGBP is safe. Severe reflux is definitely treated and is an incontestable indication with this procedure. Additionally, weight loss and diabetes are clinically improved. Our results appear to be similar to those with a primary RYGBP.

Department of Surgery, Catharina Hospital Eindhoven, Michelangelolaan 2, 5623 EJ, Eindhoven, The Netherlands.
Sleeve gastrectomy (SG) is an upcoming primary treatment modality for morbid obesity. The aim of this study was to report the indications for and the outcomes of revisional surgery after SG.
Four hundred sixteen individuals underwent a SG between August 2006 and July 2010 with a minimum
follow-up of 12 months. The patients that needed revision were identified from our prospective registry. Patients were subdivided in a first group undergoing revision as part of a two-step procedure,
a second group with failure of a secondary SG, and a third group with failure of a primary SG.
Twenty-three patients (5.5 %) had an unplanned revision.
Fourteen (3.4 %) had a two-step procedure because of super obesity.
A significant additional weight loss was achieved after revision; no complications occurred in this group.
Five patients with failure of a secondary SG had no significant additional weight loss after revision.
Reflux disease was cured. Eighteen patients in the third group showed significant additional weight loss and remission of diabetes and hypertension.
Both reflux disease and dysphagia did not heal in all affected patients after revision.
The early complication rate in the whole cohort was 23.4 %;
staple line leakage was 5.4 %, and bleeding was 8.1 %. Revision-related mortality was 0 %.
In a large series of sleeve gastrectomies, the unplanned revision rate was 5.5 %. Revision of asleeve gastrectomy is feasible in patients that do not achieve sufficient weight loss and in those patients developing complications after the initial sleeve gastrectomy.

Bariatric surgery is the most effective treatment for gastro-esophageal reflux disease (GERD) in obese patients, with the Roux-en-Y gastric bypass being the technique preferred by many surgeons. Published data reporting the results of laparoscopic sleeve gastrectomy (LSG) in patients with GERD are contradictory. In a previous observational study, we found that
*** relative narrowing of the distal sleeve, hiatal hernia (HH), and dilation of the fundus predispose to GERD after LSG.***
In this study, we evaluated the effects of standardization of our LSG technique on the incidence of postoperative symptoms of GERD.
This was a concurrent cohort study. Patients who underwent bariatric surgery at our center were followed prospectively. LSG was performed in all patients in this series.
A total of 234 patients underwent surgery. There were no cases of death, fistula, or conversion to open surgery. All 134 patients who completed 6-12 months of postoperative follow-up were evaluated. Excess weight loss at 1 year was 73.5 %. In the study group, 66 patients (49.2 %) were diagnosed with GERD preoperatively, and HH was detected in 34 patients (25.3 %) intraoperatively. HH was treated by reduction in three patients, anterior repair in 28, and posterior repair in three. Only two patients (1.5 %) had symptoms of GERD at
*** 6-12 months postoperatively. VERY SHORT FOLLOW UP ***
Our results confirm that careful attention to surgical technique can result in significantly reduced occurrence of symptoms of GERD up to 12 months postoperatively, compared with previous reports of LSG in the literature.

SHORT FOLLOW UP: Sleeve gastrectomy and crural repair in obese patients withgastroesophageal reflux disease and/or hiatal hernia.
Soricelli E, Iossa A, Casella G, Abbatini F, Calì B, Basso N.
Gastroesophageal reflux disease (GERD) with or without hiatal hernia (HH) is now recognized as an obesity-related co-morbidity. Roux-en-Y gastric bypass has been proved to be the most effective bariatric procedure for the treatment of morbidly obese patients with GERD and/or HH. In contrast, the indication for laparoscopic sleeve gastrectomy (SG) in these patients is still debated. Our objective was to report our experience with 97 patients who underwent SG and HH repair (HHR). The setting was a university hospital in Italy.
From July 2009 to December 2011, 378 patients underwent a preoperative workup for SG. In 97 patients, SG was performed with HHR. The clinical outcome was evaluated considering GERD symptom resolution or improvement, interruption of antireflux medications, and radiographic evidence of HH recurrence.
Before surgery, symptomatic GERD was present in 60 patients (15.8%), and HH was diagnosed in 42 patients (11.1%). In 55 patients (14.5%), HH was diagnosed intraoperatively. The mean follow-up was 18 months. GERD remission occurred in 44 patients (73.3%). In the remaining 16 patients, antireflux medications were diminished, with complete control of symptoms in 5 patients. No HH recurrences developed. “De novo” GERD symptoms developed in 22.9% of the patients undergoing SG alone compared with 0% of patients undergoing SG plus HHR.
SG with HHR is feasible and safe, providing good management of GERD in obese patients with reflux symptoms. Small hiatal defects could be underdiagnosed at preoperative endoscopy and/or upper gastrointestinal contrast study. Thus, a careful examination of the crura is always recommended intraoperatively.

Failure of laparoscopic sleeve gastrectomy–further procedure?
Weiner RA, Theodoridou S, Weiner S.

Worldwide, the incidence of morbid obesity is increasing, and surgery is the only effective longterm treatment. Laparoscopic sleeve gastrectomy (LSG) is associated with acceptable weight loss and reduced comorbidities. It is considered a safe procedure with sporadic complications. This publication aims to describe failures of LSG in terms of ineffective weight loss or early weight regain, and analyze secondary treatment options.
From October 2001 to December 2010, 937 patients underwent LSG in our department. Initially, all procedures were scheduled as a two-stage procedure (LSG followed by biliopancreatic diversion with duodenal switch). However, the second procedure was not performed in 64 patients (body mass index > 60 kg/m(2)). Since 2005, the frequency of second stage procedures after weight regain has been increasing; their outcome is analyzed.
Of the 937 patients, 17 (1.8%) experienced staple line leakage. Mean time to first reintervention or endoscopic stent placement was 15.6 ± 22 days (range 2-78). From 2005 to 2010, 106 secondary procedures were performed. Insufficient weight loss or weight regain were the indications in 88 cases.
*** Sixteen (15%) patients had severe gastroesophageal reflux which was resolved by Roux-en-Y gastric bypass (RYGB).
Stenosis was observed in 2 (2.6%) patients, which required endoscopic dilatation and stent placement in one case and gastric bypass in the other.
LSG is a feasible and popular bariatric procedure. Mortality (0.4%) was much higher than after gastric bypass (0.03%) and gastric banding (0%) The knowledge of potential complications and their management is crucial. All restrictive procedures require patient compliance, but increased food uptake after RYGB and LSG is common. Malabsorptive procedures are more effective for long-term weight loss. Duodenal switch and omega-loop gastric bypass are more efficient second stage procedures than re-sleeve or RYGB.

Gastroesophageal reflux disease (GERD) is highly prevalent in morbidly obese patients and a high body mass index is a risk factor for the development of this co-morbidity. The effect of laparoscopicsleeve gastrectomy (LSG) on GERD is poorly known.
We studied the effect of LSG on GERD in patients with morbid obesity. A retrospective review of 28 consecutive patients undergoing LSG for morbid obesity from September 2008 to September 2010 was performed.
A total of 28 patients, 18 women and 10 men, were identified, with a mean age of 42 years (range 18-60). The mean weight and body mass index was 166 kg and 55.5 kg/m2, respectively. The mean percentage of excess weight loss was 40% (range 17-83), with a mean follow-up time of 32 weeks (range 8-92). All patients had a pre- and postoperative upper gastrointestinal radiographic swallow study as a part of their routine care. Of these
*** patients, 18% were noted to have new-onset GERD on their postoperative upper gastrointestinal swallow test after their LSG procedure.
Using the GERD score questionnaire, all patients were interviewed to evaluate their reflux symptoms. We had a 64% response rate, with
*** 22% of patients indicating new-onset GERD symptoms despite receiving daily antireflux therapy.
*** LSG might increase the prevalence of GERD despite satisfactory weight loss.
Additional studies evaluating esophageal manometry and ambulatory 24-hours pH-metry are needed to better evaluate the effect of LSG on gastroesophageal reflux symptoms.

Third International Summit: Current status of sleeve gastrectomy.
Deitel M, Gagner M, Erickson AL, Crosby RD.
Laparoscopic sleeve gastrectomy (LSG) has been performed for morbid obesity in the past 10 years. LSG was originally intended as a first-stage procedure in high-risk patients but has become a stand-alone operation for many bariatric surgeons. Ongoing review is necessary regarding the durability of the weight loss, complications, and need for second-stage operations.
The first International Summit for LSG was held in October 2007, the second in March 2009, and this third in December 2010. There were presentations by experts, and, to provide a consensus, a questionnaire was completed by 88 attendees who had >1 year (mean 3.6 ± 1.5, range 1-8) of experience with LSG.
The results of the questionnaire were based on 19,605 LSGs performed within 3.6 ± 1.5 years (228.8 ± 275.0 LSGs/surgeon). LSG had been intended as the sole operation in 86.4% of the cases; in these, a second-second stage became necessary in 2.2%. LSG was completed laparoscopically in 99.7% of the cases. The mean percentage of excess weight loss at 1, 2, 3, 4, and 5 years was 62.7%, 64.7%, 64.0%, 57.3%, and 60.0%, respectively. The bougie size was 28-60F (mean 36F, 70% blunt tip). Resection began 1.5-7.0 cm (mean 4.8) proximal to the pylorus. Of the surgeons, 67.1% reinforced the staple line, 57% with buttress material and 43% with oversewing. The respondents excised an estimated 92.9% ± 8.0% (median 95.0%) of fundus (i.e., a tiny portion is maintained lateral to the angle of His). A drain is left by 57.6%, usually closed suction. High leaks occurred in 1.3% of cases (range 0-10%); lower leaks occurred in .5%. Intraluminal bleeding occurred in 2.0% of cases. The mortality rate was .1% ± .3%.
According to the questionnaire, presentations, and debates, the weight loss and improvement in diabetes appear to be better than with laparoscopic adjustable gastric banding and on par with Roux-en-Y gastric bypass. High leaks are infrequent but problematic.

Gastroesophageal reflux disease (GERD) is a common co-morbidity identified in obese patients. It is well established that patients with GERD and morbid obesity experience a marked improvement in their GERD symptoms after Roux-en-Y gastric bypass. Conflicting data exist for adjustable laparoscopic gastric banding and GERD. Laparoscopic sleeve gastrectomy (LSG) has become a popular adjunct to bariatric surgery in recent years. However, very little data exist concerning LSG and its effect on GERD.
A retrospective chart review was performed of 176 LSG patients from January 2006 to August of 2009. The preoperative and postoperative GERD symptoms were evaluated using follow-up surveys and chart review.
Of the 176 patients, 85.7% of patients were women, with an average age of 45 years (range 22-65). The average preoperative body mass index was 46.6 kg/m(2) (range 33.2-79.6). The average excess body weight lost at approximately 6, 12, 24 months was calculated as 54.2%, 60.7%, and 60.3%, respectively.
Of the LSG patients, 34.6% had preoperative GERD complaints.
*** Postoperatively, 49% complained of immediate (within 30 d) GERD symptoms,
*** 47.2% had persistent GERD symptoms that lasted >1 month after LSG, and
*** 33.8% of patients were taking medication specifically for GERD after LSG.
*** The most common symptoms were heartburn (46%),
*** followed by heartburn associated with regurgitation (29.2%).
In the present study,
*** LSG correlated with the persistence of GERD symptoms in patients with GERD preoperatively. Also,
*** patients who did not have GERD preoperatively had an increased risk of postoperative GERD symptoms.

Obesity and GERD: pathophysiology and effect of bariatric surgery.
Division of Gastroenterology, University Clinics of Visceral Surgery and Medicine, Bern University Hospital, Inselspital Bern, Bern, Switzerland. email@example.com
Epidemiologic, endoscopic, and pathophysiologic studies document the relationship between obesity and gastroesophageal reflux disease (GERD).
Increased body mass index and accumulation of visceral fat are associated with a two- to threefold increased risk of developing reflux symptoms and esophageal lesions. Given this association, many studies were designed to evaluate the outcome of reflux symptoms following conventional and surgical treatment of obesity.
*** Among bariatric procedures, gastric sleeve and banded gastroplasty were shown to have no effect or even worsen reflux symptoms in the postoperative setting.
Gastric banding improves reflux symptoms and findings (endoscopic and pH-measured distal esophageal acid exposure) in many patients, but is associated with de novo reflux symptoms or lesions in a considerable proportion of patients. To date,
Roux-en-Y gastric bypass is the most effective bariatric procedure that consistently leads to weight reduction and improvement of GERD symptoms in patients undergoing direct gastric bypass and among those converted from restrictive bariatric procedures to gastric bypass.

Laparoscopic sleeve gastrectomy (LSG) is frequently performed as a definitive bariatric procedure today. Quantitative data on the detailed anatomy of the stomach after LSG are yet sparse.
Thirty-two multislice computed tomography (MSCT) data sets acquired in 27 LSG patients (22 female, 5 male) with a dedicated examination protocol and post-processing were evaluated for gastric volume, stomach length, sleeve length, antrum length, staple line length, and maximum cross-sectional sleeve area. Obtained parameters were compared to time after surgery, weight loss, and the occurrence of postsurgical regurgitation.
Mean gastric volume was 186.5±88.4 ml. Gastric volume correlated significantly with the time interval after surgery. Sleeve sizes of 105.3±30.2 ml during early follow-up confirmed correct primary sizing of the sleeve,
*** whereas marked dilation to 196.8±84.3 ml was found in patients with a follow-up of 6 months and longer (p=0.038).
*** Sleeve area and staple line length were also positively correlated with time after surgery.
*** No correlation was found between gastric volume and excess weight loss.
*** In ten patients an intrathoracic migration of the staple line could be noted, with
*** four of these patients developing persistent regurgitation after LSG.
Regurgitation was present in only 2 of 17 patients without sleeve herniation.
Multislice computed tomography allows for a comprehensive and quantitative evaluation of the anatomy after LSG and thus provides new insights in the process of sleeve dilation. Intrathoracic migration of the staple line could be identified as a possible cause of persistent regurgitation.

Obesity is associated with gastroesophageal reflux disease. Roux-en-Y gastric bypass is the most performed bariatric procedure in the world, whereas sleeve gastrectomy is an emerging procedure. Both can be combined with the use of a Silastic® ring. The aim of this study was to compare the evolution of erosive esophagitis (EE) in patients who underwent Silastic® ring gastric bypass (SRGB) and Silastic® ring sleeve gastrectomy (SRSG) after a 1-year postoperative period.
We carried out a non-randomized, prospective, controlled clinical study. Sixty-five patients were enrolled based on the following inclusion criteria: female gender, age 20-60 years old, BMI 40-45 and written informed consent. The exclusion criteria were secondary obesity, alcohol or drug use, severe psychiatric disorder, binge-eating of sweets, and previous stomach or bowel surgery. The patients were divided into two groups-33 (51%) underwent SRSG and 32 (49%) patients underwent SRGB. All patients underwent an esophago-gastro-duodenoscopy during the preoperative period and at 12-14 months after the surgery.
Preoperatively, 15 patients (23.8%) were found to have erosive esophagitis, six (19.4%) in the SRSG group and nine patients (28.1%) in the SRGB group (p = 0.7795).
** Postoperatively, there was an increase in the number of patients with erosive esophagitis in the SRSG group to 14 (45.2%)
and a decrease in the SRGB group to two (6.3%), giving a total of 16 patients with EE (25.4%; p = 0.0007).
After 1 year of follow-up, we observed a worsening evolution of EE in the SRSG group, but improvement in the SRGB group.

The laparoscopic Roux Y gastric bypass (LRYGB) and the laparoscopic gastric sleeve resection are frequently used methods for the treatment of morbid obesity. Quality of life, weight loss and improvement of the co-morbidities were examined. Match pair analysis of the prospectively collected database of the 47 gastric bypass and 47 gastric sleeve resection patients operated on in our hospital was performed. The quality of life parameters were measured with two standard questionnaires (SF 36 and Moorehead-Ardelt II). The mean preoperative and postoperative BMI was in gastric bypass group 46.1 and 28.1 kg/m(2) (mean follow-up: 15.7 months) and in gastric sleeve group 50.3 and 33.5 kg/m(2) (mean follow-up: 38.3 months). The SF 36 questionnaire yielded a mean total score of 671 for the bypass and 611 for the sleeve resection patients (p = 0.06). The Moorehead-Ardelt II test signed a total score of 2.09 for gastric bypass versus 1.70 for gastricsleeve patients (p = 0.13). Ninety percent of the diabetes was resolved in the bypass and 55% in the sleeveresection group. Seventy-three percent of the hypertension patients needed no more antihypertensive treatment after gastric bypass and 30% after sleeve resection.
*** Ninety-two percent of the gastro-oesophagealreflux were resolved in the bypass group and
*** 25% in the sleeve (*** with 33% progression) group.
Ninety-four percent of the patients were satisfied with the result after gastric bypass and 90% after sleeve resection. The patients have scored a high level of satisfaction in both study groups. The gastric bypass is associated with a trend toward a better quality of life without reaching statistical significance, pronounced loss of weight and more remarkable positive effects on the co-morbidities comparing with the gastric sleeve resection.

To determine the mid- and long-term efficacy and possible side effects of laparoscopic sleevegastrectomy as treatment for morbid obesity.
SUMMARY BACKGROUND DATA:
Laparoscopic sleeve gastrectomy is still controversial as single and final treatment for morbid obesity. Some favorable short-term results have been published, however long-term results are still lacking.
In the period between November 2001 and October 2002, 53 consecutive morbidly obese patients who, according to our personal algorithm, were qualified for restrictive surgery were selected for laparoscopicsleeve gastrectomy. Of the 53 patients, 11 received an additional malabsorptive procedure at a later stage because of weight regain. The percentage of excess weight loss (EWL) was assessed at 3 and 6 years postoperatively. A retrospective review of a prospectively collected database was performed for evaluation after 3 years. Recently, after the sixth postoperative year, patients were again contacted and invited to fill out a questionnaire.
Full cooperation was obtained in 41 patients, a response rate of 78%. Although after 3 years a mean EWL of 72.8% was documented, after 6 years EWL had dropped to 57.3%, which according to the Reinhold criteria is still satisfactory. These results included 11 patients who had benefited from an additional malabsorptive procedure (duodenal switch) and 2 patients who underwent a “resleeve” between the third and sixth postoperative year. Analyzing the results of the subgroup of 30 patients receiving only sleeve gastrectomy, we found a 3-year %EWL of 77.5% and 6+ year %EWL of 53.3%. The differences between the third and sixth postoperative year were statistically significant in both groups. Concerning long-term quality of life patient acceptance stayed good after 6 + years despite the fact that late,
*** new gastro-esophageal reflux complaints appeared in 21% of patients.
In this long-term report of laparoscopic sleeve gastrectomy, it appears that after 6+ years the mean excess weight loss exceeds 50%.
*** However, weight regain and
*** de novo gastroesophageal reflux symptoms appear between the third and the sixth postoperative year.
This unfavorable evolution might have been prevented in some patients by continued follow-up office visits beyond the third year. Patient acceptance remains good after 6+ years.

Revisional vs. primary Roux-en-Y gastric bypass–a case-matched analysis: less weight loss in revisions.
Zingg U, McQuinn A, DiValentino D, Kinsey-Trotman S, Game P, Watson D.
Discipline of Surgery, University of Adelaide, Royal Adelaide Hospital, Adelaide, SA, Australia. email@example.com
With the increase in bariatric procedures performed, revisional surgery is now required more frequently. Roux-en-Y gastric bypass (RYGB) is considered to be the gold standard revision procedure. However, data comparing revisional vs. primary RYGB is scarce, and no study has compared non-resectional primary and revisional RYGB in a matched control setting. Analysis of 61 revisional RYGB that were matched one to one with 61 primary RYGB was done. Matching criteria were preoperative body mass index, age, gender, comorbidities and choice of technique (laparoscopic vs. open). After matching, the groups did not differ significantly. Previous bariatric procedures were 13 gastric bands, 36 vertical banded gastroplasties, 10 RYGB and two sleeve gastrectomies. The indication for revisional surgery was insufficient weight loss in 55 and refluxin 6. Intraoperative and surgical morbidity was not different, but medical morbidity was significantly higher in revisional procedures (9.8% vs. 0%, p = 0.031). Patients undergoing revisional RYGB lost less weight in the first two postoperative years compared with patients with primary RYGB (1 month, 14.9% vs. 29.7%, p = 0.004; 3 months, 27.4% vs. 51.9%, p = 0.002; 6 months, 39.4 vs. 70.4%, p < 0.001; 12 months, 58.5% vs. 85.9%, p < 0.001; 24 months, 60.7% vs. 90.0%, p = 0.003). Although revisional RYGB is safe and effective, excess weight loss after revisional RYGB is significantly less than following primary RYGB surgery. Weight loss plateaus after 12 months follow-up.

Due to excellent weight loss success in the short-time follow-up, sleeve gastrectomy (SG) has gained popularity as sole and definitive bariatric procedure. In the long-term follow-up, weight loss failure and intractable severe reflux can necessitate further surgical intervention.
A retrospective analysis of laparoscopic conversions from SG to Roux-en-Y gastric bypass (RYGB) was performed to assess the efficacy for reflux relief and weight loss success.
*** A total of eight out of 73 patients (11%) underwent conversion to RYGB for severe reflux (n=3) or weight regain (n=5) after a median interval of 33 months following laparoscopic sleeve gastrectomy.
In one of the patients, a banded gastric bypass was performed. In both groups, conversion to RYGB was successful, as proton pump inhibitor medication could be discontinued in all patients presenting with severe reflux, and a significant weight loss could be achieved in the patients with weight regain within a median follow-up of 33 months. Postoperative complications were observed in only one patient as leakage at the gastrojejunostomy was successfully treated by temporary stent placement.
Conversion to RYGB is an effective treatment for weight regain or intractable reflux symptoms following SG. Thus, SG can be performed, intended as sole and definitive bariatric intervention, with conversion from SG to RYGB as an exit strategy for these complications.

Due to excellent efficacy for weight loss in the short-term follow-up, sleeve gastrectomy (SG) has gained enormous popularity as bariatric procedure, not only as first step in high-risk or super-obese patients but mainly as a sole and definitive operation in morbidly obese. In contrast to a large number of short and intermediate-term results, no series of SG with a follow-up of 5 years or more has been published so far.
We report on the weight loss results of our first consecutive 26 patients with a complete follow-up of 5 years. Furthermore in a subgroup of 12 patients, plasma ghrelin levels were measured preoperatively, and up to 5 years following SG.
Weight loss defined as mean percent excess weight loss (%EWL) was found as 57.5 +/- 4.5, 60.3 +/- 5.0, 60.0 +/- 5.7, 58.4 +/- 5.4, and 55.0 +/- 6.8 (not converted, n = 21) for the first 5 years. Weight regain of more than 10 kg from nadir was observed in five (19.2%) of the 26 patients.
** Four of the patients (15.4%) were converted to gastric bypass due to severe reflux (n = 1, 3.8%) and weight loss failure (n = 3, 11.5%).
** A total of eight patients (30.8%) were at chronic need for proton pump inhibitor medication due to severe reflux.
Plasma ghrelin levels were reduced from 593 +/- 52 to 219 +/- 23 pg/ml 12 months postoperatively, with a slightly, non-significant increase toward the 5-years values of mean 257 +/- 23 pg/ml.
At 5-year follow-up, a mean EWL of 55.0 +/- 6.8% was achieved, indicating that SG leads to stable weight loss.
** Beside significant weight regain, severe reflux might necessitate conversion to gastric bypass or duodenal switch.
After an immediate reduction postoperatively, plasma ghrelin levels remained low for the first 5 years postoperatively.

Laparoscopic sleeve gastrectomy has been accepted as an option for surgical treatment of obesity. After surgery, some patients present reflux symptoms associated with endoscopic esophagitis, therefore PPI’s treatment must be indicated.
This study aims to evaluate the
** manometric characteristic of the lower esophageal sphincter (LES) before and after sleeve gastrectomy
MATERIAL AND METHOD:
This prospective study includes 20 patients submitted to esophageal manometry in order to determine the resting pressure, and total and abdominal LES length before and after the sleeve gastrectomy. Statistical variations on the LESP were validated according to Student’s “t” test.
Seventeen female and three male patients were included, with a mean age of 37.6 +/- 12.6 years. All patients reduced their body weight, from an initial BMI of 38.3 kg/m(2) to 28.2 kg/m(2) 6 months after surgery. No postoperative complications were observed in these patients. Preoperative mean LESP was 14.2 +/- 5.8 mmHg.
** Postoperative manometry decreased in 17/20 (85%), with a mean value of 11.2 +/- 5.7 mmHg (p = 0.01). Seven of them presented LESP <12 mmHg and ten patients <6 mmHg after the operation. Furthermore, the abdominal length and total length of the high pressure zone at the esophagogastric junction were affected.
** A sleeve gastrectomy produces an important decrease in LES pressure,
** which can in turn cause the appearance of reflux symptoms and esophagitis after the operation due to a partial resection of the sling fibers during the gastrectomy.

Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric procedure, and it can be done as an isolated LSG or in conjunction with biliopancreatic diversion bypass/duodenal switch (laparoscopic duodenal switch; LDS). Gastroesophageal reflux after LSG has been described, but the mechanism is unknown and the treatment in the severest cases has not been discussed. We describe a cohort of patients who have underwent an LSG or LDS, and have suffered from a severe postoperative gastroesophagealmotility disorder and/or reflux, report on their treatment, and discuss possible underlying mechanisms.
Seven hundred and six patients underwent an LSG by two of the authors (AK, AB). Sixty nine patients underwent laparoscopic sleeve gastrectomy in Hadassah Medical Center, Jerusalem, Israel (January, 2006 and December 2008; 55 isolated LSG, 14 with LDS), and 637 (212 isolated LSG, 425 LDS) in Clinica San Jorge and Alcoy Hospital in Alcoy, Spain, (January 2002 and November 2008).
Of them, eight patients who has suffered from a gastroesophageal dysmotility and reflux disease postoperatively and needed a specific treatment besides regular proton pump inhibitors (PPIs) were identified (1.1%).
A combination of
dilated upper part of the sleeve with a relative narrowing of the midstomach, without complete obstruction, was common to all eight patients who suffered from a severe gastroesophageal dysmotility and reflux.
The sleeve volume, the bougie size, and the starting point of the antral resection do not seem to have an effect in this complication.
Operative treatment was needed in only one case out of eight; in the rest of the patients, medical modalities were successful. More knowledge is required to understand the underlying mechanisms.

Laparoscopic sleeve gastrectomy (LSG) is gaining popularity as a procedure for the treatment of morbid obesity. Its indications and long-term results are currently under evaluation. Initially started as a first-stage procedure for superobese patients, it is now emerging as a standalone procedure in Asia and other parts of the world. Early results suggest that, at the end of 1 year, weight loss and resolution of comorbidities with LSG is comparable to laparoscopic Roux-en-Y gastric bypass (LRYGB). Whether LSG alone can replace LRYGB as a standard bariatric procedure is questionable. The aim of this study is to compare the results, resolution of comorbidities, and complications between LSG and LRYGB.
A retrospective comparative analysis was done of 50 patients in each arm who underwent LSG and LRYGB from October 2007 to March 2008. Both groups were matched for age, sex, and body mass index. The resolution of comorbidities, percentage of excess weight loss (EWL), and complications were studied at 6 months and 1 year in our study.
It was seen that resolution of most comorbidities such as type 2 diabetes, hypertension, dyslipidemia, sleep apnea, joint pains, and percentage of EWL in both groups was comparable at the end of 6 months and 1 year. Though early resolution of type 2 diabetes was seen to be better in the LRYGB group, the results matched up at 1 year.
** There was increased incidence of gastroesophageal reflux disease in LSG patients.
On comparison, it was also observed that the Asian studies have shown better results with LSG when compared to studies done in a largely Caucasian population.
Long-term studies are needed to evaluate the efficacy of LSG alone as a procedure for the treatment of morbid obesity and its comorbidities.

Laparoscopic sleeve gastrectomy (LSG) has been used as a first step of a two-stage approach in bariatric surgery for high-risk patients. Recently, LSG is being utilized as a primary and final procedure for morbid obesity with acceptable short-term results. The aim of this study is to investigate the effectiveness of LSG as a revisional procedure for patients with unsatisfactory outcomes after laparoscopic adjustable gastric band (LAGB). A retrospective review of a prospectively maintained database was performed. Data were reviewed for all patients undergoing revision from LAGB to LSG during the period May 2005 and May 2009. Data collected included demographics, indication for revision, operative time, length of stay, postoperative complications, and degree of weight reduction. Fifteen patients (three males and 12 females) had revisional surgery converting a LAGB to a LSG. The indication in four patients (26.66%) was weight regains and in five patients (33.33%) was poor weight loss;
four patients (26.66%) had a band slippage and symptoms of gastroesophageal reflux, and one patient (6.66%) had poor weight loss, band slippage, and reflux.
In one patient (6.66%), the indication was slippage and duodenal fistula. One-step revision procedure was done in 13 patients (86.66%), while two-step procedure was done in two patients (13.33%). Mean preoperative weight and BMI were 233.02 (181.4-300) lb and 38.66 (29.7-49.3) kg/m2, respectively. Mean weight loss at 2, 6, 12, 18, and 24 months postoperatively was 20.7, 48.3, 57.2, 60.1, and 13.5 lb, respectively. Mean % excess BMI loss was 28.9%, 64.2%, 65.3%, 65.7%, and 22.25% at 2, 6, 12, 18, and 24 months, respectively. There was one major complication (staple line leak) and one postoperative acute gastric outlet obstruction. We had no mortality. Thirteen patients were followed up postoperatively. The number decreased as follow-up time progressed. LSG could provide short-term weight loss after previously failed LABG, but prone to more complications compared to an initial LSG without a prior bariatric procedure.

Sleeve gastrectomy (SG) is a rapid and comparatively simple bariatric operation, which thus far shows good resolution of co-morbidities and good weight loss. The potential peri-operative complications must be recognized and treated promptly. Like other bariatric operations, there are variations in technique. Laparoscopic SG was initially performed for high-risk patients to increase the safety of a second operation. However, indications for SG have been increasing. Interaction among those performing this procedure is necessary, and the Second International Consensus Summit for SG (ICSSG) was held to evaluate techniques and results.
A questionnaire was filled out by attendees at the Second ICSSG, held March 19-22, 2009, in Miami Beach, and rapid responses were recorded during the consensus part.
Findings are based on 106 questionnaires representing a total of 14,776 SGs. In 86.3%, SG was intended as the sole operation. A total of 81.9% of the surgeons reported no conversions from a laparoscopic to an open SG. Mean +/- SD percent excess weight loss was as follows: 1 year, 60.7 +/- 15.6; 2 years, 64.7 +/- 12.9; 3 years, 61.7 +/- 11.4; 4 years 64.6 +/- 10.5; >4 years, 48.5 +/- 8.7. Bougie size was 35.6F +/- 4.9F (median 34.0F, range 16F-60F). The dissection commenced 5.0 +/- 1.4 cm (median 5.0 cm, range 1-10 cm) proximal to the pylorus. Staple-line was reinforced by 65.1% of the responders; of these, 50.9% over-sew, 42.1% buttress, and 7% do both. Estimated percent of fundus removed was 95.8 +/- 12%; many expressed caution to avoid involving the esophagus. Post-operatively, a high leak occurred in 1.5%, a lower leak in 0.5%, hemorrhage in 1.1%, splenic injury in 0.1%, and later stenosis in 0.9%.
*** Post-operative gastroesophageal reflux ( approximately 3 mo) was reported in 6.5% (range 0-83%).
Mortality was 0.2 +/- 0.9% (total 30 deaths in 14,776 patients). During the consensus part, the audience responded that there was enough evidence published to support the use of SG as a primary procedure to treat morbid obesity and indicated that it is on par with adjustable gastric banding and Roux-en-Y gastric bypass, with a yes vote at 77%.
SG for morbid obesity is very promising as a primary operation.

Morbid obesity is associated with gastroesophageal reflux (GERD). The aim of this prospective study was to determine esophageal motility in asymptomatic morbidly obese patients and compare it to non-obese individuals.
Forty-seven morbidly obese patients without GERD symptoms and 15 normal weight individuals were divided into four groups according to their body mass index (BMI; group I, <30 kg/m2; group II, 35-39.9 kg/m2; group III, 40-49.9 kg/m2; group IV, >or=50 kg/m2). Standard stationary water-perfused manometry was performed for the assessment of anatomy and function of the lower esophageal sphincter (LES). Twenty-four-hour ambulatory pH-metry and measurement of esophageal motility were performed with a microtransducer sleeve catheter. Data are given as mean+/-SD, and the results of groups II-IV were compared to the non-obese individuals from group I.
Patients with morbid obesity had significantly lower LES pressures than non-obese individuals (I, 15.1+/-4.9; II-IV, 10.5+/-5.4, mmHg, p<0.05 vs. I) and showed an altered esophageal motility with respect to contraction frequency (I, 1.8+/-0.7/min; II-IV, 3.6+/-2.5/min; p<0.05 vs. I) and contraction amplitude (I, 38+/-12 mmHg; II-IV, 33+/-17 mmHg; p<0.05 vs. I). Furthermore, these patients had significantly higher DeMeester scores than non-obese individuals. Length and relaxation of the LES as well as propulsion velocity of the tubular esophagus did not differ.
*** Patients with morbid obesity (=BMI>40 kg/m2) have a dysfunction of the LES and an altered esophageal motility, even when they are asymptomatic for GERD symptoms.

In previous publications, we demonstrated the safety and short-term efficacy of laparoscopicsleeve gastrectomy (LSG) as a final step in the treatment of morbid obesity (MO). This study aimed to assess the mid-term efficacy of LSG.
We performed a retrospective review of a prospectively collected database. Between November 2004 and January 2007, 130 consecutive patients underwent LSG as a final procedure to MO. Data including patient demographics, operative time, length of hospital stay, complications, preoperative body mass index (BMI), complications, and weight loss at 3, 6, 12, 18, and 24 months were recorded and analyzed.
The mean age was 45.6 (range: 12-79) years while the mean BMI was 43.2 (range: 30.2-75.4) kg/m(2). The mean operative time was 97 (range, 58-180) min and all operations were completed laparoscopically. The mean hospital stay was 3.2 (range, 1-19) days with zero mortality in this series. One patient (0.7%) had leakage at the stapler line, while four patients (2.8%) developed trocar site infection.
*** Three patients (2.1%) complained of symptoms of gastroesophageal reflux disease (GERD),
three patients (2.1 %) developed symptomatic gallstones, and trocar site hernia was present in one (0.7%) patient. The mean weight loss was 21, 31.2, 37.4, 39.5, and 41.7 kg at 3, 6, 12, 18, and 24 months, respectively, while the mean BMI decreased to 36.9, 32.8, 29.5, 28, and 27.1 at 3, 6, 12 18, and 24 months, respectively. Percent of excess weight loss (%EWL) was 33.1, 50.8, 62.2, 64.4, and 67.9 at 3, 6, 12, 18, and 24 months, respectively.
LSG is a safe and effective surgical procedure for the morbidly obese up to 2 years. Excess body weight loss seems to be acceptable at 2 years postoperatively.

Some institutions perform sleeve gastrectomy (SG) as the initial operation for high-risk, high body mass index patients planning a definitive weight loss operation in 12-18 months. Other institutions consider SG a viable alternative to other bariatric operations. SG is frequently debated among the bariatric surgeons. Many questions remain about the current state of SG. Should it be performed as a definitive weight loss procedure or as a bridge for another bariatric procedure? Is there a specific BMI at which point SG should be encouraged? Is the weight loss comparable to other bariatric procedures? Is there a higher risk of gastric leak? What is the appropriate sleeve size? What are the hormonal benefits?
*** Does SG predispose to gastroesophageal reflux disease?
What is the mechanism of weight loss? Are long-term results available? And what are the complications? We conducted an extensive literature review aiming to resolve these commonly asked questions.

Is preoperative manometry in restrictive bariatric procedures necessary?
Klaus A, Weiss H.
Department of General and Transplant Surgery, Medical University Innsbruck, Anichstrasse 35, Innsbruck, Austria. firstname.lastname@example.org
Restrictive bariatric procedures are frequently considered for patients with morbid obesity, because the weight loss and reduction of comorbidities are good.
*** An impact on gastroesophageal refluxdisease (GERD), which is common in this population, may be anticipated.
Converse results of GERD symptoms are reported for patients after adjustable gastric banding (AGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGBP).
A literature search was performed and, with our personal experience, are summarized.
Esophageal manometry is a practical tool to identify functional disorders of the esophageal body and the lower esophageal sphincter (LES).
*** For patients with weak esophageal body motility, AGB should not be considered as a therapeutic option because esophageal dilation, esophageal stasis, and consequent esophagitis often occur during long-term follow-up, and band deflation is inevitable.
Stable body weight can therefore not be achieved in these patients.
*** Low resting pressure of the LES may be a contraindication for SG, because taking away the angle of His further impairs the antireflux mechanism at the cardia.
So far, RYGBP is an option for all morbidly obese patients regardless of the results of esophageal manometry.
*** Preoperative esophageal manometry is advised for restrictive procedures such as AGB and SG.

Good results obtained after laparoscopic sleeve gastrectomy (LSG), in terms of weight loss and morbidity, have been reported in few recent studies. Our team has designed a multicenter prospective study for the evaluation of the effectiveness and feasibility of this operation as a restrictive procedure.
From January 2003 to September 2006, 163 patients (68% women) with an average age of 41.57 years, were operated on with a LSG. Indications for this procedure were morbid obese [body mass index (BMI)>40 kg/m2] or severe obese patients (BMI>35 kg/m2) with severe comorbidities (diabetes, sleep apnea, hypertension…) with high-volume eating disorders and superobese patients (BMI>50 kg/m2).
The average BMI was 45.9 kg/m2. Forty-four patients (26.99%) were superobese, 84 (51.53%) presented with morbid obesity, and 35 (21.47%) were severe obese patients. Prospective evaluations of excess weight loss, mortality, and morbidity have been analyzed. Laparoscopy was performed in 162 cases (99.39%). No conversion to laparotomy had to be performed. There was no operative mortality. Perioperative complications occurred in 12 cases (7.36%). The reoperation rate was 4.90% and the postoperative morbidity was 6.74% due to six gastric fistulas (3.66%), in which four patients (2.44%) had a previous laparoscopic adjustable gastric banding.
*** Long-term morbidity was caused by esophageal reflux symptoms (11.80%).
The percentage of loss in excessive body weight was 48.97% at 6 months, 59.45% at 1 year (120 patients), 62.02% at 18 months, and 61.52% at 2 years (98 patients). No statistical difference was noticed in weight loss between obese and extreme obese patients.
The sleeve gastrectomy seems to be a safe and effective restrictive bariatric procedure to treat morbid obesity in selected patients. LSG may be proposed for volume-eater patients or to prepare superobese patients for laparoscopic gastric bypass or laparoscopic duodenal switch. However, weight regained, quality of life, and evolution ofmorbidities due to obesity need to be evaluated in a long-term follow up.

Gastric distention: a mechanism for postprandial gastroesophageal reflux.
Holloway RH, Hongo M, Berger K, McCallum RW.
The occurrence of gastroesophageal reflux after meals may be related to an increase in the rate of transient lower esophageal sphincter (LES) relaxations, the mechanisms of which are not understood. We investigated the effects of gastric distention on LES pressure in 16 normal subjects and 17 patients with gastroesophageal reflux disease. Intraluminal pressure was measured in the gastric fundus, LES, and esophageal body with a manometric catheter incorporating a sleeve device. Gastric distention was performed by injecting 0, 250, 500, or 750 ml of air in randomized order into a balloon and maintaining each stimulus for 15 min. Gastric distention did not significantly alter resting LES pressure in either group. During the basal period the rate of transient LES relaxation in the reflux patients (1.1 +/- 0.4 per 15 min) was greater than that in the normal subjects (0.6 +/- 0.1 per 15 min). Gastric distention resulted in a significant threefold to fourfold increase in the rate of transient LES relaxations in both groups. The reflux patients had a significantly greater proportion of complete relaxations (87%) than did the normal subjects (73%). We conclude that gastric distention, by significantly increasing the rate of transient LES relaxations in both normal subjects and patients with gastroesophageal reflux disease, may contribute to the postprandial increase in gastroesophageal reflux.
