Abstract
Bariatric surgery is the most effective obesity treatment. As a chronic and progressive disease, weight loss response to surgery will vary individually. Thus, insufficient weight loss or regain can happen after surgery, but they lack a standard definition. There are different mechanisms underlying weight regain and/or insufficient weight loss, such as genetics, maladaptive eating behaviors, and the inadequate choice of index operations, among others. Patients with weight regain or insufficient weight loss should be submitted to an individualized and comprehensive evaluation by a multidisciplinary team. This may help identify the causes and direct the appropriate treatment individually. Options for patients with insufficient weight loss and/or weight regain following bariatric surgery include repair of postoperative complications, conversion into another operation, endoscopic therapies with inconsistent outcomes, and dietary/behavioral counseling. Revision and conversion surgeries have higher complication rates than primary operations. Although there is no standard pharmacological regimen for that indication, the new agents seem efficient and safe to promote the loss of the regained weight and even be adjunctive to selected patients before they reach the plateau. This review aims to summarize the knowledge of the best approach for patients with weight regain/insufficient weight loss and suggests an algorithm to customize the approach and therapeutic options after bariatric surgery.

Resizing of the Gastric Pouch for Weight Regain after Laparoscopic Roux-en-Y Gastric Bypass and One-Anastomosis Gastric Bypass: Is It a Valid Option? J Clin Med 2022; 11:jcm11216238. [PMID: 36362466 PMCID: PMC9659038 DOI: 10.3390/jcm11216238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/17/2022] [Accepted: 10/19/2022] [Indexed: 11/06/2022] Open
Abstract
Introduction: The laparoscopic resizing of the gastric pouch (LPR) has recently been proposed as a revisional technique in the case of weight regain (WR) after gastric bypass procedures. The aim of this study was to report our experience with LPR for WR. Materials and Methods: All patients with WR ≥ 25% after gastric bypass and with a dilated gastric pouch and/or gastrojejunal anastomosis who underwent LPR between January 2017 and January 2022 were retrospectively reviewed. From a radiological point of view, a gastric pouch was considered dilated when its volume was calculated at >80 cm3 for LRYGB and >200 cm3 for OAGB upon a 3D-CT scan. The endoscopic criterion considered both the diameter of the gastrojejunal anastomosis and the gastric pouch volume. All anastomoses > 20 mm for LRYGB and >40 mm for OAGB were considered dilated, while a gastric pouch was considered endoscopically dilated when the retrovision maneuver with the gastroscope was easily performed. These selection criteria were arbitrarily established on the basis of both our personal experience and literature data. Results: Twenty-three patients had LPR after a Roux-en-Y gastric bypass or one-anastomosis gastric bypass. The mean BMI at LPR was 36.3 ± 4.7 kg/m2. All patients underwent LPR, while the resizing of the GJA was also performed in 3/23 (13%) cases, and hiatoplasty was associated with the resizing of the pouch in 6/23 cases (26.1%). The mean BMI at the last follow-up was 29.3 ± 5.8 kg/m2. The difference between the BMI before resizing and the BMI at the last follow-up visit was statistically significant (p = 0.00005). The mean %TWL at 24.2 ± 16.1 months was 19.6 ± 9%. Comorbidities had an overall resolution and/or improvement rate of 47%. The mean operative time was 71.7 ± 21.9 min. The conversion rate was nil. Postoperative complications occurred in two cases (8.7%). Conclusions: In our series, LPR for WR showed good results in weight loss and in improvement/resolution of comorbidities, with an acceptable complication rate and operative time. Only further studies with a greater cohort of patients and a longer postoperative follow-up will be able to highlight the long-term benefits of this technique.

Weight Recidivism and Dumping Syndrome after Roux-En-Y Gastric Bypass: Exploring the Therapeutic Role of Transoral Outlet Reduction. J Pers Med 2022; 12:jpm12101664.

Abstract
Obesity is a chronic, relapsing disease representing a global epidemic. To date, bariatric surgery is the most effective treatment for morbid obesity in the long-term. Roux-en-Y gastric bypass (RYGB) is one of the most performed bariatric interventions, with excellent long-term outcomes. However, about one-third of patients may experience weight regain over time, as well as dumping syndrome. Both these conditions are challenging to manage and require a multidisciplinary and personalized approach. The dilation of the gastro-jejunal anastomosis is a recognized etiological factor for both weight regain and dumping syndrome. Dietary modifications, behavioral interventions, and medications represent the first therapeutic step. Revisional surgery is the traditional approach when non-invasive treatments fail. However, re-interventions may be technically difficult and are associated with increased morbidity and mortality. Transoral outlet reduction (TORe) is an endoscopic procedure aimed at reducing the size of the anastomosis and is proposed as a minimally invasive treatment of weight regain and/or dumping syndrome refractory to conservative therapies. This review is aimed at providing a narrative overview of the role of TORe as part of the multidisciplinary therapeutic toolkit nowadays available to approach weight regain and dumping syndrome after RYGB.

Single Anastomosis Jejuno-ileal (SAJI): a New Model of Malabsorptive Revisional Procedure for Insufficient Weight Loss or Weight Regain After Roux-en-Y Gastric Bypass. Obes Surg 2022; 32:3194-3204. [PMID: 35763129 DOI: 10.1007/s11695-022-06174-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 03/13/2022] [Accepted: 03/18/2022] [Indexed: 01/19/2023]
Abstract
BACKGROUND In case of insufficient weight loss or weight regain or relapse of weight-related comorbidities after Roux-en-Y gastric bypass (RYGB), other procedures such as reduction of a large gastric pouch and stoma, lengthening of the Roux limb, conversion to sleeve gastrectomy and/or bilio-pancreatic diversion with duodenal switch have been advocated. Single anastomosis jejuno-ileal (SAJI) is a new revisional simple operation performed after RYGB failure which adds malabsorption to the previous gastric bypass. METHODS SAJI includes a single jejuno-ileal anastomosis specifically joining the ileum 250-300 cm proximal to the ileo-caecal valve and the jejunum 30 cm below the gastro-jejunal anastomosis on the Roux limb of the previous RYGB. Thirty-one patients underwent SAJI for insufficient weight loss and/or weight regain after RYGB. The percent total weight loss (%TWL) after RYGB and before SAJI was 21.8 ± 7.8. All SAJI operations were performed laparoscopically. The SAJI mean operating time was 145 min. RESULTS Regarding weight loss after SAJI, %TWL is 27.2 ± 7.4, 31.2 ± 6.4, 33.7 ± 5.9 and 32.9 ± 5.2 at 12, 24, 36 and 48 months, respectively. Our series recorded a low rate of peri-operative and medium-term complications with a low grade of severity (Clavien-Dindo classification grade). One patient required reoperation 36 days after SAJI for epigastrium incarcerated incisional hernia at the previous RYGB laparotomy site. Mortality was 0. Comorbidity reduction/resolution after SAJI is 83.2% for type 2 diabetes mellitus, 42.8% for arterial hypertension, 72.8% for dyslipidemia and 45.3% for OSA. CONCLUSIONS Treatment of failed RYGB is challenging. SAJI is a less complicated, purely low invasive malabsorptive operation that should reach satisfactory %TWL and comorbidity reduction/resolution.

Obes Surg 2021; 31:4295-4304.

Abstract
PURPOSE Although Roux-en-Y gastric bypass (RYGB) is one of the most common bariatric procedures, insufficient weight loss is described to be as high as 20-35%. To treat weight regain/inadequate weight loss, laparoscopic adjustable gastric banding (LAGB) could be a feasible revisional strategy. MATERIALS AND METHODS We report on a prospective study which included 35 patients who presented inadequate weight loss or significant weight regain after primary RYGB (percentage excess weight loss [%EWL] at revision < 50%). All patients underwent revisional LAGB with the placement of an Adhesix® Bioring® adjustable gastric band (Cousin Biotech, Wervicq-Sud, France). Patients' weight loss, complications, frequency of revisions and quality of life were evaluated. RESULTS Follow-up data at 24 months are available for 80% of the included patients. The mean BMI before RYGB was 43.6 ± 5.4 kg/m2 and before revisional LAGB was 38.8 ± 4.3kg/m2. The %EWL before revisional surgery was 23.3 ± 24.8%. The average time between both procedures was 6.7 (mean) ± 3.6 (SD) years. Twenty-four months after revisional LAGB, the average BMI calculated from the weight at RYGB dropped to 32.0 ± 4.5 kg/m2, with an additional %EWL of 49.9 ± 30.3% resulting in a total %EWL of 60.7 ± 28%. The reoperation rate for complications related to LAGB was 21.2%. No band erosions occurred, but two bands needed to be removed during the study. CONCLUSION Revisional LAGB may be considered a valid salvage procedure in patients with weight regain or inadequate weight loss after RYGB, though band- and port-related complications remain a notable concern.

Abstract
BACKGROUND Of patients undergoing Roux-en-Y gastric bypass (RYGB), 15-35% of patients fail to achieve "adequate" weight loss or regain significant weight. Multiple solutions have been proposed, but not well studied. We report our experience with limb distalization with lengthening the biliopancreatic (BP) limb and shortening the common channel (CC). METHODS We retrospectively reviewed data from patients undergoing laparoscopic limb distalization for excess weight loss (EWL) <50% or BMI >35 kg/m2 after RYGB from 2012 to 2017. The BP limb was lengthened and CC was shortened to 100-200 cm. Perioperative outcomes such as morbidity, weight loss, nutritional deficiencies, comorbidity remission, and operative details were analyzed. RESULTS Twenty-two patients were included. The mean BMI prior to RYGB was 54.1 ± 8.5 kg/m2 and 43.0 ± 5.5 kg/m2 prior to limb distalization. The mean follow-up was 18.3 ± 12.9 months with a mean BMI change, %EWL, and %TWL (total weight loss) of 11.8 ± 7.4 kg/m2, 62.3 ± 32.4%, and 25.4 ± 14.4%, respectively. The total mean BMI change, %EWL, and %TWL from RYGB was 22.2 ± 9.9 kg/m2, 77.8 ± 23.6%, and 40.2 ± 13.3%, respectively. Of patients with persistent comorbidities, remission rates of diabetes, hypertension, and gastroesophageal reflux disease were 100%, 17%, and 38%, respectively. The mean operative time was 132.6 ± 54.4 min and mean hospital stay was 2.2 ± 1.3 days. Overall morbidity was 27.3%. Three patients (13.6%) developed nutritional deficiencies requiring reversal surgery. CONCLUSION In patients with inadequate weight loss or weight regain after RYGB, limb distalization with lengthening of the BP limb is an effective procedure for additional weight loss and further improvement of comorbidities. Nutritional complications are a risk, but can be minimized with close follow-up and patient compliance.

Abstract
OBJECTIVES To compare the short-term safety and effectiveness of long biliopancreatic limb Roux-en-Y gastric bypass (RYGB) to that of regular RYGB. SETTING Academic hospital, United States. METHODS A retrospective chart review was performed on 89 consecutive patients who underwent RYGB between February 4, 2014 and March 12, 2015. Of these, 43 underwent long biliopancreatic limb RYGB (150 versus 60 cm, with 100-cm Roux limb). RESULTS Baseline characteristics including sex, preoperative body mass index, and co-morbidities were similar between the long- and regular-limb RYGB patients. Long-limb patients were older than regular-limb patients. The median length of hospital stay was similar (2 d for both groups). In the long-limb RYGB group, the mean percentage of excess body mass index loss was 50.3%, 71.4%, 75.8%, and 80.5% at 6, 12, 24, and 36 months after the procedure, respectively. In the regular-limb RYGB group, the mean excess body mass index loss was 51.8%, 71.7%, 69.3%, and 68.5% during the same follow-up period. No significant difference in weight loss was observed between the 2 groups at any time point. Two patients in each group required 30-day readmission (4.7% and 4.3%). Two patients in each group required 30-day reoperation. One death occurred in the regular limb group due to a cerebrovascular accident after discharge. CONCLUSIONS Short-term results show that long biliopancreatic limb RYGB was not associated with a more significant weight loss after RYGB. The 2 procedures were similar in 30-day complications.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is a well-established surgical method for morbid obesity; however, weight regain (WR) after initially good results may be considered an issue, the treatment of which has found no consensus yet. OBJECTIVES The aim of this study was to compare the different surgical methods treating WR after RYGB that are used at the Vienna Medical University in a larger number of patients, concerning further weight loss, complications, and reoperations. SETTING University hospital, Austria. METHODS This study includes all patients with RYGB who were reoperated due to WR at the Vienna Medical University by December 2016 (n = 84). The follow-up rate was 93%. The following 4 approaches to treating WR after RYGB were taken: (1) pouch resizing, (2) pouch banding, (3) pouch resizing plus pouch banding, and (4) common limb shortening (i.e., distalization). RESULTS The mean maximum excess weight loss referring to the WR procedure in the 4 groups was as follows: group 1: 69.0% ± 35.2%, group 2: 62.8% ± 39.5%, group 3: 83.1% ± 30.9%, and group 4: 81.5% ± 41.6%. Reoperations occurred in the following different groups: group 1 had 2 balloon dilations (20%), groups 2 (n = 13) and 3 (n = 29) had 5 (38% and 17%) band removals each, and group 4 had 9 reversal procedures due to malnutrition (30%). CONCLUSIONS There are nonsignificant differences in terms of additional weight loss between the different methods. However, differences lay in the areas of adverse symptoms and further reoperations. While there was no risk of malnutrition with pouch resizing, there was with distalization. Pouch banding (with or without resizing) poses a higher risk of dysphagia.

Abstract
BACKGROUND Many surgeons prefer a narrow gastrojejunostomy in gastric bypass believing that this provides greater weight loss. The question is whether the anastomosis remains at its initial diameter, whether it narrows or widens over time. This study tests the hypothesis that the initial diameter of the anastomosis varies over time. MATERIALS AND METHODS One hundred obese had undergone surgery. Group A with anastomosis 1.5 cm wide and group B with anastomosis 3 cm wide. One-year follow-up was done for 83 patients. The size of the anastomosis diameter was evaluated using a balloon for cardia dilation. RESULTS Comparing the results of surgery with the values presented 1 year after the procedure, (i) BMI decreased from 43.3 ± 6.6 to 28.7 ± 7.0 kg/m2 for group A and 44.6 ± 5.9 to 29.1 ± 6.3 kg/m2 for group B, (ii) the total weight loss was 30.6 ± 4.7% for group A and 31.9 ± 5.2% for group B, and (iii) the initial 1.5-cm anastomosis in group A measured 2.3 ± 1.0 cm while the initial 3-cm anastomosis in group B measured 2.7 ± 1.0 cm 1 year after surgery. No statistically significant difference was found for any of the variables evaluated before and after the surgical procedure. CONCLUSION Calibrated anastomosis has no utility in increasing weight loss in gastric bypass.

Abstract
BACKGROUND Weight regain has led to an increase in revision of Roux-en-Y gastric bypass (RYGB) surgeries. There is no standardized approach to revisional surgery after failed RYGB. We performed an exhaustive literature search to elucidate surgical revision options. Our objective was to evaluate outcomes and complications of various methods of revision after RYGB to identify the option with the best outcomes for failed primary RYGB. METHOD A systematic literature search was conducted using the following search tools and databases: PubMed, Google Scholar, Cochrane Clinical Trials Database, Cochrane Review Database, EMBASE, and Allied and Complementary Medicine to identify all relevant studies describing revision after failed RYGB. Inclusion criteria comprised of revisional surgery for weight gain after RYGB. RESULTS Of the 1200 articles found, only 799 were selected for our study. Of the 799, 24 studies, with a total of 866 patients, were included for a systematic review. Of the 24 studies, 5 were conversion to Distal Roux-en-y gastric bypass (DRYGB), 5 were revision of gastric pouch and anastomosis, 6 were revision with gastric band, 2 were revision to biliopancreatic diversion/duodenal switch (BPD/DS), and 6 were revision to endoluminal procedures (i.e., stomaphyx). Mean percent excess body mass index loss (%EBMIL) after revision up to 1 and 3-year follow-up for BPD/DS was 63.7 and 76 %, DRYGB was 54 and 52.2 %, gastric banding revision 47.6 and 47.3 %, gastric pouch/anastomosis revision 43.3 and 14 %, and endoluminal procedures at 32.1 %, respectively. Gastric pouch/anastomosis revision resulted in the lowest major complication rate at 3.5 % and DRYGB with the highest at 11.9 % when compared to the other revisional procedures. The mortality rate was 0.6 % which only occurred in the DRYGB group. CONCLUSION All 866 patients in the 24 studies reported significant early initial weight loss after revision for failed RYGB. However, of the five surgical revision options considered, BPD/DS, DRYGB, and gastric banding resulted in sustained weight loss, with acceptable complication rate.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is associated with approximately 25 % weight loss failure, resulting in insufficient weight loss or weight regain. Strategies of revisional surgery focus on alteration of limb length, pouch or stoma size. Altering pouch size and outlet by adding laparoscopic adjustable gastric band (LAGB) might initiate further weight loss. The goal of this study is to review the safety and efficacy of LAGB after failed RYGB in a retrospective cohort of patients in our institute. METHODS Patients with secondary LAGB (n = 44) were studied between May 2012 and January 2015. Demographics, effects on weight loss and complications were analysed. RESULTS Mean age and body mass index (BMI) at time of LAGB was 45.8 ± 8.2 years and 37.2 ± 5.4 kg/m2, respectively. Mean interval between RYGB and LAGB was 2.6 ± 1.3 years. Mean follow-up was 14 ± 7.9 months, with 25 % loss to follow-up at 12 months. Due to LAGB, patients lost an additional 17.6 % ± 28.3 % excess weight. Patients with weight regain after initial weight loss success showed more excess weight loss (EWL) compared to patients whom never reached 50% EWL after RYGB. Overall complication and reoperation rates were 30 and 21 %, respectively, with 16 % band removal. One fatality due to septic shock following band erosion was observed. CONCLUSION In this largest published cohort, secondary banding of failed RYGB provides only limited additional weight loss. Furthermore, this technique is associated with high morbidity and reoperation rates. A significant difference in effect was found between patients with weight loss failure and weight regain. Larger prospective series are necessary to evaluate if the modest benefits are worth the risks of secondary LAGB.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (RYGB) is an effective treatment modality for severe obesity. Failure of weight loss and/or weight regain due to lack of restriction has been reported in long-term follow-up studies. The aim of this study is to determine the safety and effectiveness of reestablishing the restrictive component of the operation by trimming the pouch and/or anastomosis for pouch and/or anastomotic enlargement using a laparoscopic approach. METHODS We retrospectively reviewed our prospectively collected database for all patients that underwent revisional surgery of RYGB for weight regain or failure of weight loss. Percent excess weight loss (%EWL) and BMI loss (BMIL) were characterized into the following three time periods: (1) primary operation to pre-revision, (2) pre-revision to post-revision, and (3) primary operation to post-revision. Post-operative follow-up was at 6, 12, 18, 24, 36, and 48 months. RESULTS Between 2005 and 2011, a total of 121 patients in the database underwent revision of RYGB. Forty-four patients were identified that fulfilled the aforementioned parameters. In this group, 30 patients underwent trimming of the pouch and/or redo anastomosis (TPA), 8 TPA and conversion from retrocolic to antecolic Roux limb, and 6 TPA with remnant gastrectomy. Mean follow-up period was 26.1 ± 22.7 months. The post-revision mean %EWL was 38%, and the BMI loss was 7 kg/m(2). In the pre-revision to 48 months post-revision time period, mean %EWL and BMIL were 28.6% and 4.9 kg/m(2) in the TPA-only group, 52% and 8.8 kg/m(2) in the TPA with conversion to antecolic, antegastric group, and 33.4% and 5.9 kg/m(2) in the TPA with gastrectomy group, respectively (%EWL, p = 0.096; BMIL, p = 0.227). One patient (2.3%) developed a left upper quadrant hematoma. There was no mortality in this series. CONCLUSIONS Trimming of the pouch and/or anastomosis appears to be a safe and effective revisional modality for patients with insufficient weight loss or weight regain after gastric bypass in the hands of experienced surgeons.

Abstract
In the literature, weight regain or failure of weight loss has been reported in up to 35% of patients after Roux-en-Y gastric bypass (RYGB). Several revisional procedures have been suggested to reinitiate further weight loss in this group of patients, and placing a silastic ring around the pouch proximal to the gastrojejunostomy is one among those procedures. The aim of our study is to evaluate and compare the safety and efficacy of salvage banding using a pericardial patch after RYGB for further weight loss. Between December 2009 and April 2013, a total of 46 patients underwent revision with pericardial patch ring after RYGB for weight regain/failure of weight loss. A retrospective review of a prospectively collected database was performed, noting the outcomes and complications of the procedure. The mean body mass index at the time of revision was 40.1 ± 6.8 kg/m2. Mean percentage of excess weight loss was 23.4 ± 15.7%, 39.0 ± 27.4%, and 18.9 ± 20.5% at 6, 12 and 24 months after revision, respectively. Eight (17.4%) patients required a total of 11 readmissions due to nausea, vomiting, dysphagia and abdominal pain. Six (13.0%) patients underwent a total of six reoperations, including four patients with laparoscopic removal of the pericardial patch and another revision of RYGB, and two patients with repair of perforated ulcers. Revision with pericardial patch ring after gastric bypass for weight regain or failure of weight loss may not be feasible, safe and effective.

Abstract
BACKGROUND Placement of an adjustable gastric band (AGB) over the gastric pouch after RYGB failure has had varied results. The aim of this study was to evaluate safety and outcomes of AGB after RYGB failure. METHODS Twenty-eight patients who underwent laparoscopic placement of an AGB around the gastric pouch as a revisional procedure for inadequate weight loss or recidivism after RYGB between 2008-2011 were identified. RESULTS Twenty-four (86%) patients had a dilated gastric pouch and/or stoma. The mean operative and adhesiolysis times were 137.9±52.3 minutes and 83±51 minutes, respectively. History of a previous open RYGB was associated with a longer adhesiolysis time (P = .03). Three (11%) major intraoperative and 5 (18%) early postoperative complications occurred. Late complications (all requiring band removal) were observed in 6 (21%) patients and included ineffectiveness (n = 2), dysphagia/esophageal dilation (n = 2), band erosion (n = 1), and peritonitis (n = 1). In all 4 patients with a normal-sized pouch and stoma at the time of band placement, the band was removed. After a mean follow-up of 38.3±14.8 months, the mean body mass index (BMI) change and median excess weight loss (EWL) after salvage banding were -3.6±4.5 kg/m(2) and 12.7%, respectively. In the subset of patients with a dilated pouch/stoma, BMI less than 42 kg/m(2) at the time of band placement was associated with a significantly higher EWL (41.4%±37.0%) compared with a baseline BMI>42 kg/m(2) (12.1%±7.2%, P = .03). CONCLUSIONS Salvage banding is technically challenging due to dense adhesions, carries significant morbidity, and is associated with only 13% additional EWL. However, this approach may still be an option in carefully selected patients, such as those with previous laparoscopic RYGB who have a dilated pouch and/or stoma and lower BMI.

Abstract
BACKGROUND There are growing numbers of patients who require revisional bariatric surgery due to the undesirable results of their primary procedures. The aim of this study was to review our experience with bariatric patients undergoing revisional surgery. METHODS We conducted a retrospective analysis to review the indications for revisional bariatric procedures and assess their postoperative outcomes. RESULTS From 04/04 to 01/11, 2,918 patients underwent bariatric surgery at our institution. A total of 154 patients (5.3%) of these cases were coded as revisional procedures. The mean age at revision was 49.1 ± 11.3 and the mean BMI was 44.0 ± 13.7 kg/m2. Revisional surgery was performed laparoscopically in 121 patients (78.6%). Laparoscopic revisions had less blood loss, shorter length of hospital stay, and fewer complications compared to open revisions. Two groups (A and B) were defined by the indication for revision: patients with unsuccessful weight loss (group A, n = 106) and patients with complications of their primary procedures (group B, n = 48). In group A, 74.5% of the patients were revised to a bypass procedure and 25.5% to a restrictive procedure. Mean excess weight loss was 53.7 ± 29.3% after revision of primary restrictive procedures and 37.6 ± 35.1% after revision of bypass procedures at >1-year follow-up (p < 0.05). In group B, the complications prompting revision were effectively treated by revisional surgery. CONCLUSIONS Revisional bariatric surgery effectively treated the undesirable results from primary bariatric surgery. Laparoscopic revisional surgery can be performed after both failed open and laparoscopic bariatric procedures without a prohibitive complication rate. Carefully selected patients undergoing revision for weight regain have satisfactory additional weight loss.

Abstract
Bariatric surgery is the most effective therapy to treat obesity and its sequelae. With the increasing incidence of obesity, the number of bariatric procedures has dramatically increased in recent years. The perioperative morbidity reached a very low level, and nearly all revisional bariatric procedures are primarily minimally invasive today. About 10-25% of the patients undergoing bariatric surgery require a revision at some point after their initial operation. Consequently, revisional bariatric surgery has emerged as a distinct practice, performed mainly at tertiary centers, to resolve complications caused by the primary operation and to provide satisfactory weight loss. In this review, our personal experience with revisional bariatric surgery is discussed against the background of the available literature. We further attempt to define major indications for revisional bariatric surgery and balance them with perioperative and long-term morbidity as well as the surgical outcome.

Abstract
Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has emerged as the gold standard for the management of morbid obesity. Accordingly, patients who fail to lose weight after LRYGB present a difficult problem for the bariatric surgeons. A literature review was performed to evaluate the management options for this select bariatric population. Methods: A literature search was conducted in the EMBASE and MEDLINE databases using the most comprehensive timeline. All relevant articles were identified and full texts were obtained and reviewed. Results: Thirteen articles were retrieved based on key word searches. Management for weight failure following LRYGB included revision using the following options: laparoscopic adjustable gastric banding, pouch/anastomotic revision with or without endoluminal techniques, laparoscopic distal Roux-en-Y gastric bypass, and laparoscopic biliopancreatic diversion with duodenal switch. Laparoscopic sleeve gastrectomy may be considered in patients who fail LRYGB with nutritional deficiencies. Conclusion: Failed LRYGB should be managed based on the patient presentation and diagnostic evaluation. Patients may present with significant nutritional deficiencies/complications, failure to lose weight, or weight recidivism. A treatment algorithm is proposed based on the literature to guide bariatric surgeons with respect to management options. However, given the paucity of research with respect to this problem, additional studies are needed to provide more insight on the optimal surgical management.

Abstract
Recently obesity has been defined as a disease and has turned bariatric surgery into a part of a chronic illness management. Obesity induces several comorbidities leading to cardiovascular disease and mortality. The effects of bariatric surgery on these comorbidities used to be classified as weight-loss induced. However bariatric surgery has recently been termed metabolic surgery because of the suspected direct, weight loss independent effect of bariatric procedures on the physiopathological mechanisms causing excess fat storage and insulin resistance. This review describes the standard procedures commonly performed and their specific outcomes on metabolic diseases in order to work towards more patient tailored treatment of obesity and to reduce side effects. Furthermore this review focuses on gaps in understanding the pathogenesis of obesity and its treatment with bariatric surgery. Surgery failures as well as new techniques are discussed and evaluated.

Abstract
BACKGROUND Weight regain (WR) occurs in some patients after laparoscopic Roux-en-Y gastric bypass (LRYGBP). Loss of restriction due to dilation of the gastrojejunostomy (GJS) or the gastric pouch might be the main cause for WR. With different techniques available for the establishment of the GJS, the surgical technique might influence long-term success. METHODS We present a 5-year follow-up for weight loss and WR of a matched-pair study comparing circular stapled (CSA) to linear stapled (LSA) GJS in a series of 150 patients who underwent primary antecolic antegastric LRYGBP. Complete 5-year follow-up was obtained for 79 % of the patients. RESULTS Excess BMI loss (EBL) at 3 months was better with the CSA (p = 0.02) and comparable thereafter. The 5-year %EBL was 67.3 ± 23.2 vs. 73.3 ± 24.3 % (CSA vs. LSA, p = 0.19) WR of > 10 kg from nadir was found in 24 patients (16 %) with higher incidence in CSA than in LSA patients (20 % vs. 12 %). The %WR was comparable for both groups, 16 ± 13 vs. 15 ± 19 % (CSA vs. LSA, p = 0.345). Eleven patients underwent surgical re-intervention for WR by placement of a non-adjustable band (n = 2), adjustable band (n = 7) and conversion to distal gastric bypass (n = 2). CONCLUSIONS CSA and LSA lead to comparable weight loss in this 5-year follow-up. More patients in the CSA group had WR. Weight regain of more than 10 kg was found in one out of seven patients within 5 years postoperatively.

Abstract
BACKGROUND The Roux-en-Y gastric bypass (RYGB) performed laparoscopically (LRYGB) is the most frequently performed bariatric procedure in Belgium. However, late results in terms of weight loss or weight regain are inconsistent and may warrant a second procedure. This retrospective study analyzes the laparoscopic options for revisional surgery after LRYGB. METHODS Between January 1, 2001 and December 31, 2009, 70 patients underwent a new laparoscopic procedure for poor weight loss or weight regain after LRYGB. The revisional procedure was performed a median of 2.6 years after the initial bypass operation. Fifty-eight patients were available for follow-up (82.9 %); 19 underwent distalization; and 39 a new restrictive procedure. RESULTS The mean mass index (BMI) before the revisional procedure was 39.1 + 11.3 kg/m(2) (30.8-51.8), down from 42.7 + 19.7 kg/m(2) (33.0-56.6) initially, which corresponded to a percentage of excess weight loss (EWL) of 12.4 + 9.3 % (-1.0-29.1). After the corrective procedure, with a follow-up of approximately 4 years, mean BMI was 29.6 + 12.4 kg/m(2) (18.0-45.5), for a significant additional percentage of EWL of 53.7 + 9.8 % (2.0-65.8). The overall complication rate was 20.7 %, and the reoperation rate was 7.3 %. The overall leak rate was 12.1 %. Patients suffering from leaks could consistently be treated conservatively or by stent placement. Two patients needed reconversion after distal bypass. The satisfaction index was good in just over 50 % of the patients. CONCLUSION Revisional laparoscopic surgery after RYGB performed for weight issues provides good additional weight loss but carries significant morbidity. Leaks can usually be handled non-surgically. Patient satisfaction is only fair.

Abstract
BACKGROUND Single incision laparoscopic bariatric surgery has developed over the last few years, with single incision laparoscopic adjustable gastric banding (SILS-AGB) being performed most commonly. However, there are no randomised controlled trials and few matched studies comparing SILS-AGB to conventional laparoscopic multi-port multiport adjustable gastric banding (LAGB). Our aim was to study any differences in outcome and analgesic requirements between two matched groups of gastric band patients (SILS-AGB and LAGB). METHODS Between June 2009 and September 2010, 111 patients underwent SILS-AGB and 99 patients underwent LAGB performed by a single surgeon (AGP). Patients were matched for age, sex, weight, BMI and co-morbidities. Forty six SILS-AGB and LAGB patients were included for analysis. Their outcomes were compared for operating times, conversions, analgesia requirements, morbidity and mortality. RESULTS Patients characteristics between the SILS-AGB and LAGB groups were similar with no differences in their median age (44 vs 47 years), sex (m:f; 7:39 vs 4:42), body mass index (43.1 vs 44.4 kg/m(2)) or co morbidities respectively. In the SILS-AGB group the median operating time (70 min) was not significantly longer than in LAGB group (61.5 min, p = 0.07). However, SILS-AGB patients used less opiates (p < 0.01) than the LAGB patients. There was no difference in morbidity, mortality or readmission rates. CONCLUSION SILS-AGB is a safe and feasible option and is comparable with LAGB. Post operative demand for analgesia was significantly less in the SILS-AGB group. Further comparisons of post operative pain and long term outcomes are required; however preliminary results are promising.

Abstract
BACKGROUND Laparoscopic adjustable gastric banding is a popular and effective restrictive bariatric procedure. However, with longer follow-up, it has become clear that a considerable number of patients require revisional surgery, of which Roux-en-Y gastric bypass (RYGB) is the most commonly performed procedure. Studies that compared the outcomes of primary RYGB and revisional RYGB have not been conclusive. Our objective was to determine whether significant differences exist in the 1-year outcomes between primary RYGB (prim-RYGB) and revisional RYGB after laparoscopic adjustable gastric banding (rev-RYGB) at a major training hospital in The Netherlands. METHODS All prim-RYGB and rev-RYGB procedures performed from 2007 to 2009 were analyzed. Data were collected regarding weight loss, hospitalization, operative time, postoperative complications, and co-morbidities. RESULTS A total of 292 RYGB procedures were performed: 66 rev-RYGB and 226 prim-RYGB procedures. The operative time was significantly shorter in the prim-RYGB group (136.6±37.5 versus 167.5±40.6 min; P<.0001). No significant differences were found in hospitalization time (4.4±1.7 versus 4.9±2.4 d; P= .063) or complication rate (14.7% versus 15.2%; P=.962). No deaths occurred in either group. The number of patients with resolved diabetes and hypertension did not differ between the 2 groups (50.1% versus 23.1%; P=.116; and 40.7% versus 25.0%; P=.384, respectively). Weight loss was significantly greater in the prim-RYGB group in terms of excess weight loss (71.6%±20.8% versus 48.4%±26.8%; P<.0001), body mass index reduction (13.0±3.8 versus 10.2±5.6 kg/m(2); P<.0001), absolute weight loss (37.4±11.5 versus 29.3±17.2 kg; P=.001), and percentage of weight loss (29.7%±8% versus 21.7%±11.5%; P<.0001). CONCLUSION rev-RYGB is a safe procedure with outcomes similar to those of prim-RYGB in terms of complication rate, hospitalization time, and effect on co-morbidity. Weight loss, however, was significantly less after rev-RYGB than after prim-RYGB.

Abstract
With the increase in bariatric surgical procedures, an increase in revision operations is expected. A thorough preoperative work-up is essential to formulate an appropriate revision strategy. Outcomes vary according to the primary operation and chosen approach to revision. Recent studies have shown acceptably low complication rates and good weight loss with the associated health benefits. Although there is no direct evidence in the form of randomized studies indicating which patients with inadequate weight loss or weight regain will benefit most from revision, or to support one particular revision approach rather than another, it is possible to develop general, effective strategies.

Abstract
BACKGROUND Enlargement of the gastric pouch and/or gastrojejunostomy after Roux-en-Y gastric bypass (RYGB) is postulated to be the antecedent to suboptimal weight loss or weight regain. The present study evaluated the gastric pouch and stoma dimensions in RYGB patients and correlated them with the weight loss outcomes. METHODS Patients who underwent upper endoscopy for investigation of gastrointestinal symptoms or weight regain after RYGB were identified. The stoma was considered enlarged if >2 cm in diameter and the pouch was considered enlarged if >6 cm long or >5 cm wide. Successful weight loss was defined as excess weight loss >50% or a body mass index decrease to ≤ 30 kg/m(2). RESULTS A total of 380 patients had nondiagnostic upper endoscopy findings at a mean post-RYGB interval of 5.9 ± 4.0 years. Among these were 175 patients (group A; 87% women) who had successful weight loss and 205 patients (group B; 86% women) who were referred for investigation of weight regain. The pouch and stoma size were normal in most of the patients in group A (63.4%) compared with 28.8% of the patients in group B (P <.001). The most common abnormality was an enlarged stoma. The pouch length, pouch volume, and stoma diameter correlated inversely with excess weight loss. Multivariate analysis identified that the stoma diameter was independently associated with weight regain after RYGB. CONCLUSION The current definition of a "normal" size pouch/stoma is associated with optimal weight loss after RYGB, although this might need to be reviewed. Patients who regain weight are likely to have abnormal anatomy, in particular, stoma enlargement. The surgical RYGB technique and methods of evaluating the gastric anatomy in RYGB patients need to be standardized, intraoperatively and postoperatively.

Abstract
BACKGROUND The objective of this study was to study the long-term outcome of adjustable gastric banding in the treatment of morbid obesity. In Europe, the preference for gastric band has declined in favor of Roux-Y-gastric bypass. METHODS This is a follow-up of a prospective study on a large cohort of patients after laparoscopic gastric banding (LAGB) for morbid obesity. RESULTS Complete data were collected on 656 patients (88%) from a cohort of 745 patients. After a median follow-up of 95 months (range 60-155), the mean BMI dropped from 41.0 ± 7.3 to 33.2 ± 7.1 kg/m², with a 46.2 ± 36.5% excess weight loss (EWL). A more than 50% EWL was achieved in 44% of patients. The band was still in place in 77.1% of patients; conversion to gastric bypass after band removal was carried out in 98 (14.9%) patients, while a simple removal was done in only 52 (7.9%) patients. Band removal was more likely in women and patients with a higher BMI. CONCLUSIONS After LAGB, band removal was necessary for complications or insufficient weight loss in 24% of patients. Nearly half of the patients achieved a more than 50% EWL, but in 88%, a more than 10% EWL was observed. LAGB can achieve an acceptable weight loss in some patients, but the failure in one out of four patients does not allow proposing it as a first-line option for the treatment of obesity.

Abstract
BACKGROUND Weight regain after Roux-en-Y gastric bypass (RYGB) is one of the possible complications bariatric surgeons are confronted with. An option for enhancing weight loss is the conversion of RYGB into distal RYGB (DRYGB), which is a malabsorptive procedure. We report the technical strategy and the preliminary outcomes of conversion of RYGB to DRYGB by laparoscopy. PATIENTS AND METHODS Between April 2005 and November 2009, 7 patients benefited from laparoscopic conversion of RYGB to DRYGB for weight regain mainly due to a new dietary behavior, namely, polyphagia (eating too frequent meals). At the time of RYGB, the mean weight and BMI was 120.5 ± 26.4 kg and 43.2 ± 6.7 kg/m(2), respectively. Five patients suffered of obesity-related comorbidities. Mean interval time between RYGB and conversion was 41 ± 15.9 months. At the time of conversion, the mean weight, BMI, % excess weight loss were 100.7 ± 19.8 kg, 36.1 ± 4.8 kg/m(2), and 33.7% ± 12.1%, respectively. Obesity-related comorbidities at that time affected 4 patients. RESULTS Mean operative time was 122.1 ± 34 minutes. There were no conversions to open surgery and no mortality. Postoperatively, 1 patient suffered of a bleeding. Mean hospital stay was 4.7 ± 2.5 days. After a mean follow-up of 19 ± 23.7 months, the mean weight, BMI, and % excess weight loss was 82.5 ± 19.7 kg, 29.5 ± 5.3 kg/m(2), and 57.6% ± 8.1%, respectively. Obesity-related comorbidities remained unchanged after the conversion in the 4 patients. One patient required a surgical reoperation for internal hernia. CONCLUSION Conversion of RYGB to DRYGB for weight regain can safely be performed by laparoscopy, with satisfactory early results.

Abstract
BACKGROUND As the number of weight loss operations has increased, the number of patients who have failed to maintain sufficient weight loss has also increased, providing a management challenge to the bariatric surgeon. Conversion to a duodenal switch with omentopexy and feeding jejunostomy was performed for these patients. METHODS Between September 2006 and January 2010, 41 revisional operations were performed at 1 institution and by 1 operating surgeon. The data were prospectively collected and reviewed for several parameters, including excess weight loss, mortality, and morbidity. These results are reported. RESULTS A total of 41 patients underwent conversion of their original bariatric operation to a duodenal switch with omentopexy and feeding jejunostomy. The initial operations had been gastric bypass in 32 patients, vertical banded gastroplasty in 5, and laparoscopic adjustable gastric banding in 4. The average excess weight loss was 54% in 31 patients at 6 months, 66% in 22 patients at 1 year, and 75% in 9 patients at 2 years. No patients died. The average hospital stay was 6.4 days. A total of 9 proven or suspected leaks (22%) developed. One was at the enverted staple line of a jejunojejunostomy that was diagnosed and treated the next day with little subsequent morbidity. The others were at the gastrogastrostomy or lateral gastric staple line and all occurred in conversions from gastric bypass. They were all ischemic type leaks and presented 5-11 days after surgery and closed relatively uneventfully with J-tube feedings and antibiotic/antifungal treatment. Other major complications included 1 pulmonary embolism (2%), 1 small bowel obstruction at the site of the feeding jejunostomy (2%), 2 stenoses (4%)-1 at the duodenoenterostomy and 1 in the body of the vertical gastrectomy. This gives a total major complication rate of 30%. A total of 3 patients required reoperation because of a jejunojejunostomy leak, small bowel obstruction, and stenosis at the vertical gastrectomy. No gastrogastrostomy leaks required surgical or radiologic intervention. One required revision for malnutrition, but otherwise the nutrition remained good. CONCLUSION Revisional surgery to a duodenal switch is a complex operation and carries a high potential for major complications. Nonetheless, it can be accomplished safely with good long-term results. Omentopexy, drainage, and feeding jejunostomy should be considered at surgery to treat the high potential for delayed ischemic leaks.

Abstract
BACKGROUND Studies reporting the revisionary options for weight loss failure after Roux-en-Y gastric bypass (RYGB) have been complex, underpowered, and lacking long-term data. We have previously shown that short-term (12-month) weight loss is achievable with laparoscopic adjustable gastric banding (LAGB) for failed RYGB. To report the midterm outcomes of LAGB after RYGB failure. METHODS A retrospective review of prospectively collected data before and after RYGB, when available, and before and after LAGB was performed at the New York Langone University Hospital (New York, NY). The data collected included weight, height, body mass index (BMI), gender, race, age, operative time, length of stay, postoperative complications, and the percentage of excess weight loss. RESULTS A total of 43 patients (9 men and 34 women) underwent LAGB after weight loss failure with RYGB. Of the 43 patients, 27 patients had undergone RYGB at other institutions, and preoperative RYGB data were available for 23 total patients. The average interval to LAGB was 6.6 years. The mean BMI before RYGB was 50.4 kg/m(2) and before LAGB was 43.3 kg/m(2) (%EWL was 17% after RYGB). At follow-up after LAGB, the average BMI was 35.2 kg/m(2), with a %EWL of 38% (calculated from LAGB only) at 26 months (range 6-66). At the 1- and 2-year follow-up visit, the BMI had decreased by 8.7 kg/m(2). The reoperation rate for complications related to LAGB was 10% and included 2 band erosions, 1 band slip, and 1 port flip. CONCLUSION The results of our study have shown that LAGB had good midterm data as a revisionary procedure for weight loss failure after RYGB.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGBP) is presently one of the most popular surgical procedures for obesity. One of the possible long-term problems is weight regain, usually after a period of successful weight loss. Weight regain after RYGBP can be due to new eating habits, like sweet-eating or grazing, or volume eating because of impaired restriction. This paper reports our experience in patients who presented weight regain after laparoscopic RYGBP, because of new appearance of volume eating or hyperphagia, treated by the laparoscopic placement of a non-adjustable silicone ring around the gastric pouch. METHODS From July 2004 to November 2007, six patients affected by weight regain due to hyperphagic behavior, benefited from revision of RYGBP consisting of the placement of a non-adjustable silicone ring loosely encircling the stomach part. Mean weight and body mass index (BMI) at the time of RYGBP were 105.0 kg +/- 12.3 and 36.3 +/- 3.0 kg/m(2), respectively, and all patients suffered from obesity-related co-morbidities. After a mean time from RYGBP of 26.0 +/- 14.2 months, patients presented a weight regain of 4.7 +/- 3.4 kg compared with their minimal weight, with a final mean weight, BMI, and percentage of excess weight loss (%EWL) at the time of the silicone ring of 86.0 +/- 13.1 kg, 29.5 +/- 3.9 kg/m(2), and 47.0 +/- 24.7%, respectively. Preoperative evaluation for each patient included history and physical examination, nutritional and psychiatric evaluation, laboratory tests, and barium swallow check. Outcome measures included evaluation of the Roux-en-Y construction, operative time, postoperative morbidity and mortality, and weight loss in terms of absolute weight loss, BMI, and %EWL. RESULTS Any modification of the digestive circuit was evidenced. Mean operative time was 82.5 +/- 18.3 min. No operative mortality and no conversion to open surgery were achieved. No postoperative complications were achieved. Mean hospital stay was 2.6 +/- 1.5 days. After a mean follow-up of 14.0 +/- 9.2 months, the six patients presented a mean weight loss of 9.1 +/- 2.4 kg, with a final mean weight, BMI, and %EWL of 76.8 +/- 13.7 kg, 26.4 +/- 4.2 kg/m(2), and 70.4 +/- 30.4%, respectively. Difference in term of %EWL before and after revision (23.4 +/- 5.7) is statistically significant (p < 0.05). There have been no erosions or slippage of the ring during this follow-up. CONCLUSION One of the possible causes of weight regain after RYGBP is the new eating behavior of the patient, one of which is hyperphagia. Treatment of this condition can be the placement of a non-adjustable silicone ring loosely fitted around the gastric pouch which contributes to improved weight loss.
