Abstract
Background Weight regain following primary bariatric surgery is attributed to anatomical, behavioural and hormonal factors. Dilation of the gastrojejunal anastomosis is a possible cause of weight regain after roux-en-Y gastric bypass (RYGB). However, surgical revision has significant risks with limited benefits. Endoluminal procedures have been suggested to manage weight regain post-surgery. This systematic review aims to assess efficacy of endoluminal procedures. Methods Studies where endoluminal procedures were performed following primary bariatric surgery were identified. Main outcome measures were mean weight loss pre- and post-procedure, excess weight loss, recurrence rates, success rates and post-procedure complications. Results Twenty-six studies were included in this review. Procedures identified were (i) endoluminal plication devices (ii) other techniques e.g. sclerotherapy, mucosal ablation, and Argon Plasma Coagulation (APC) and (iii) combination therapy involving sclerotherapy/mucosal ablation/APC and endoscopic OverStitch device. Endoluminal plication devices show greatest initial weight loss within 12 months post-procedure, but not sustained at 18 months. Only one study utilising sclerotherapy showed greater sustained weight loss with peak EWL (19.9%) at 18 months follow-up. Combination therapy showed the greatest sustained EWL (36.4%) at 18 months. Endoluminal plication devices were more successfully performed in 91.8% of patients and had lower recurrence rates (5.02%) compared to sclerotherapy and APC, with 46.8% success and 21.5% recurrence rates. Both procedures demonstrate no major complications and low rates of moderate complications. Only mild complications were noted for combination therapy. Conclusions The paucity of good quality data limits our ability to demonstrate and support the long-term efficacy of endoluminal techniques in the management of weight regain following primary bariatric surgery. Future work is necessary to not only clarify the role of endoluminal plication devices, but also combination therapy in the management of weight regain following primary bariatric surgery.

Abstract
INTRODUCTION With the cumulative increase in the number of patients undergoing bariatric surgery, postoperative weight regain has become a considerable challenge. Mechanisms for weight regain are not fully understood and the process is likely multifactorial in many cases. Endoluminal revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective and less invasive management strategy for this population. AREAS COVERED We critically review data from case series, retrospective and prospective studies, and meta-analyses pertaining to weight regain after gastric bypass. A variety of endoscopic revision approaches are reviewed, including technique details, procedural safety and efficacy, and post-procedure care. EXPERT COMMENTARY Given the proliferation of endoluminal therapies with evidence showing safety and efficacy in the treatment of weight regain, it is likely that endoscopic revision will be the gold standard to treat weight regain in patients with gastric bypass.

Abstract
During the last years we have been witnessing a significant increase in the number and type of bariatric endoscopic techniques: we have different types of balloons, suture systems, injection of substances and malabsorptive prosthesis, etc. Also, some endoscopic revisional procedures for patients with weight regain after bariatric surgery have been incorporated. This makes it necessary to protocolize, position and regularize all these techniques, through a consensus that allows their clinical application with the maximum medical rigor and scientific evidence available.

Abstract
Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric procedure. Despite its high efficacy, some patients regain part of their lost weight. Several endoscopic therapies have been introduced as alternatives to treat weight regain, but most of the articles are relatively small with unclear long-term data. To systematically assess the efficacy of endoscopic therapies for weight regain after RYGB. We searched MEDLINE, EMBASE, Scopus, Web of Science, Cochrane, OVID, CINAHL/EBSCo, LILACS/Bireme, and gray literature. Primary outcomes were absolute weight loss (AWL), excess weight loss (EWL), and total body weight loss (TBWL). Thirty-two studies were included in qualitative analysis. Twenty-six described full-thickness (FT) endoscopic suturing and pooled AWL, EWL, and TBWL at 3 months were 8.5 ± 2.9 kg, 21.6 ± 9.3%, and 7.3 ± 2.6%, respectively. At 6 months, they were 8.6 ± 3.5 kg, 23.7 ± 12.3%, and 8.0 ± 3.9%, respectively. At 12 months, they were 7.63 ± 4.3 kg, 16.9 ± 11.1%, and 6.6 ± 5.0%, respectively. Subgroup analysis showed that all outcomes were significantly higher in the group with FT suturing combined with argon plasma coagulation (APC) (p < 0.0001). Meta-analysis included 15 FT studies and showed greater results. Three studies described superficial-thickness suturing with pooled AWL of 3.0 ± 3.8, 4.4 ± 0.07, and 3.7 ± 7.4 kg at 3, 6, and 12 months, respectively. Two articles described APC alone with mean AWL of 15.4 ± 2.0 and 15.4 ± 9.1 kg at 3 and 6 months, respectively. Full-thickness suturing is effective at treating weight regain after RYGB. Performing APC prior to suturing seems to result in greater weight loss. Head-to-head studies are needed to confirm our results. Few studies adequately assess effectiveness of other endoscopic techniques.

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 Despite initial successful weight loss, some patients may experience weight regain following Roux-en-Y gastric bypass (RYGB). OBJECTIVE To assess the impact of weight regain on bariatric patients' quality of life (QoL). METHODS This was a prospective cross-sectional study. Fifty-six consecutive RYGB patients were recruited and divided into weight-regain and weight-stable cohorts. QoL was assessed using the Bariatric Quality of Life (BQL) questionnaire. The BQL Index scores of the weight-regain and weight-stable groups were compared using Student's t-test. Additionally, the BQL Index score of the weight-regain group was compared with that of historical prebariatric patients. Predictors of BQL were assessed using univariate and multivariate linear regression analyses. RESULTS Of 56 RYGB patients, 41 (73%) had weight regain. On average, patients had body mass index (BMI) of 37 ±7.5 kg/m2 and gained 34 ±26% of maximal weight initially lost. Weight-regain patients had lower BQL Index scores than weight-stable patients (44.8±6 vs 53±7, p<0.001). Patients with weight regain had similar BQL Index scores as the prebariatric patients despite lower BMI (BMI of 39.7±6.8 vs 47.2±7.6, p<0.05; BQL Index of 44.8±6 vs 41.6±10.4, p=0.144, respectively). Years from RYGB, BMI and amount of weight regain were associated with BQL Index on a univariate analysis (β=-0.55,-0.52, -0.7; p<0.0001). Only weight regain was a significant predictor of BQL on a multivariate analysis (β =-0.56; p=0.001). CONCLUSION Weight regain had a negative impact on bariatric patients' QoL. Patients who regained at least 15% of maximal weight lost appeared to have as low QoL as those who had not undergone bariatric surgery despite a lower BMI.

Abstract
As lifestyle and diet patterns have become westernized in East Asia, the prevalence of obesity has rapidly increased. Bariatric surgeries, such as Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric banding (LAGB), are considered the first-line treatment option in patients with severe obesity. However, postoperative complications have increased and the proper management of these complications, including the use of endoscopic procedures, has become important. The most serious complications, such as leaks and fistulas, can be treated with endoscopic stent placement and injection of fibrin glue, and a novel full-thickness closure over-the-scope clip (OTSC) has been used for treatment of postoperative leaks. Stricture at the gastrojejunal (GJ) anastomosis site after RYGB or incisura angularis in SG can be managed using stents or endoscopic balloon dilation. Dilation of the GJ anastomosis or gastric pouch may lead to failure of weight loss, and the use of endoscopic sclerotherapy, novel endoscopic suturing devices, and OTSCs have been attempted. Intragastric migration of the gastric band can be successfully treated using various endoscopic tools. Endoscopy plays a pivotal role in the management of post-bariatric complications, and close cooperation between endoscopists and bariatric surgeons may further increase the success rate of endoscopic procedures.

Abstract
Obesity and its comorbidities - including diabetes and obstructive sleep apnea - have taken a large and increasing toll on the United States and the rest of the world. The availability of commercial, clinical, and operative therapies for weight management have not been effective at a societal level. Endoscopic bariatric therapy is gaining acceptance as more effective than diet and lifestyle measures, and less invasive than bariatric surgery. Various endoscopic therapies are analogues of the restrictive or bypass components of bariatric surgery, utilizing gastric remodeling or intestinal anastomosis to achieve proven weight loss and metabolic benefits. Others, such as aspiration therapy, employ novel mechanisms of action. Intragastric balloons have recently been approved by the United States Food and Drug Administration, and a number of other technologies have completed large multicenter trials (such as AspireAssist aspiration therapy and Primary Obesity Surgery Endolumenal). Endoscopic sleeve gastroplasty and transoral outlet reduction for endoscopic revision of gastric bypass have proven safe and effective in a number of studies. As devices are approved for use, data will continue to accumulate for safety, effectiveness, and cost effectiveness. Bariatric endoscopists should be prepared to appropriately target and apply various endoscopic bariatric therapies in the context of a comprehensive long-term weight management program.

Abstract
Obesity is a global epidemic with significant morbidity and mortality. Weight loss results in reduction of health risks and improvement in quality of life, thus representing a goal of paramount importance. Bariatric surgery is the most efficacious choice compared to conservative alternatives including diet, exercise, drugs and behavioral modification to treat obese patients. Following bariatric operations, patients may present with upper gastrointestinal tract complaints that warrant endoscopic evaluation and the various bariatric surgery types are often linked to complications. A subset of these complications necessitates endoscopic interventions for accurate diagnosis and effective, minimal invasive treatment. This review aims to highlight the role of upper gastrointestinal endoscopy in patients who have undergone bariatric surgery to evaluate and potentially treat surgery-related complications and upper gastrointestinal symptoms.

Abstract
BACKGROUND Approximately 20-30 % of patients who undergo Roux-en-Y gastric bypass (RYGB) will not meet the goals of weight loss surgery. Revisional surgery is associated with higher morbidity compared to initial operative management, and results in terms of weight loss have been inconsistent. Endoscopic plication has been seen as a less invasive option, with encouraging initial results. The objective was to analyze the outcomes after Restorative Obesity Surgery, Endolumenal (ROSE) procedure. METHODS We retrospectively analyzed patients who underwent ROSE between 5/2008 and 11/2013. All patients had failure of weight loss or regain weight after RYGB. Demographics, operative data, and follow-up were recorded. RESULTS Twenty-seven patients underwent ROSE. One patient was excluded due to lack of follow-up. Twenty-five (96 %) patients were female. Mean time since initial RYGB was 11.9 ± 4.3 years. Mean initial weight and BMI were 236 ± 47 lb and 40.6 ± 8.1 kg/m(2), respectively. Mean OR time was 77 ± 30 min. Preoperative average pouch length and stoma diameter were 6.8 ± 2.3 and 2.1 ± 0.7 cm, respectively. On average, 4 ± 1.6 stitches were placed. Final pouch length and stoma diameter were 3.4 ± 1.6 (50 % reduction) and 0.86 ± 0.4 cm (61 % reduction). A total of 12 (46 %) and seven (28 %) patients underwent EGD at 3 and 12 months postoperatively. The mean pouch length and stoma diameter were 5 ± 1.9 (26.5 % reduction) and 1.2 ± 0.7 cm (42.9 % reduction) at 3 months and 6.14 ± 1.6 (10 % reduction) and 2.2 ± 1.2 cm (4.7 % increase) at 12 months, respectively. The %EWL was 8.9, 9.3, 8, 6.7, -10.7, -13.5, -5.8, -4.5 at 3, 6, 12, 24, 36, 48, 60, and 72 months, respectively. CONCLUSION Although endoscopic plication achieved the intended reduction in the pouch and stoma diameter at 3 months, these tend toward the preoperative diameter at 12 months. This anatomical failure and the lack of follow-up may explain why most patients failed to achieve sustainable weight loss.

Abstract
A new paradigm in the treatment of obesity and metabolic disease is developing. The global obesity epidemic continues to expand despite the availability of diet and lifestyle counseling, pharmacologic therapy, and weight loss surgery. Endoscopic procedures have the potential to bridge the gap between medical therapy and surgery. Current primary endoscopic bariatric therapies can be classified as restrictive, bypass, space-occupying, or aspiration therapy. Restrictive procedures include the USGI Primary Obesity Surgery Endolumenal procedure, endoscopic sleeve gastroplasty using Apollo OverStitch, TransOral GAstroplasty, gastric volume reduction using the ACE stapler, and insertion of the TERIS restrictive device. Intestinal bypass has been reported using the EndoBarrier duodenal-jejunal bypass liner. A number of space-occupying devices have been studied or are in use, including intragastric balloons (Orbera, Reshape Duo, Heliosphere BAG, Obalon), Transpyloric Shuttle, and SatiSphere. The AspireAssist aspiration system has demonstrated efficacy. Finally, endoscopic revision of gastric bypass to address weight regain has been studied using Apollo OverStitch, the USGI Incisionless Operating Platform Revision Obesity Surgery Endolumenal procedure, Stomaphyx, and endoscopic sclerotherapy. Endoscopic therapies for weight loss are potentially reversible, repeatable, less invasive, and lower cost than various medical and surgical alternatives. Given the variety of devices under development, in clinical trials, and currently in use, patients will have multiple endoscopic options with greater efficacy than medical therapy, and with lower invasiveness and greater accessibility than surgery.

Abstract
Endoscopic suturing had previously been considered an experimental procedure only performed in a few centers and often by surgeons. Now, however, endoscopic suturing has evolved sufficiently to be easily implemented during procedures and is more commonly used by gastroenterologists. We have employed the Apollo OverStitch suturing device in a variety of ways including closure of perforations, closure of full thickness defects in the gastrointestinal wall created during endoscopic full thickness resection, closure of mucosotomies during peroral endoscopic myotomy, stent fixation, fistula closure, post endoscopic submucosal dissection, endoscopic mucosal resection and Natural Orifice Transluminal Endoscopic Surgery defect closures, post-bariatric surgery gastrojejunal anastomosis revision and primary sleeve gastroplasty.

Abstract
The results of lifestyle interventions and pharmacotherapy are disappointing in severe obesity which is characterised by premature death and many obesity-associated co-morbidities. Only surgery may achieve significant and durable weight losses associated with increased life expectancy and improvement of co-morbidities. Bariatric surgery involves the gastrointestinal tract and may therefore increase gastrointestinal complaints. Bariatric surgery may also result in complications which in many cases can be solved by endoscopic interventions. This requires a close cooperation between surgeons and endoscopists. This chapter will concentrate on the most commonly performed operations such as the Roux-en-Y gastric bypass, the adjustable gastric banding and the sleeve gastrectomy, in the majority of cases performed by laparoscopy. Operations such as the vertical banded gastroplasty and the biliopancreatic diversion with or without duodenal switch will not be discussed at length as patients with these operations will not be encountered frequently and their management can be found under the headings of the other operations.

Abstract
BACKGROUND We report our initial experience and 6-month outcomes in a single center using the per-oral Incisionless Operating Platform™ (IOP) (USGI Medical) to place transmural plications in the gastric fundus and distal body using specialized suture anchors (the Primary Obesity Surgery Endolumenal [POSE] procedure). METHODS A prospective observational study was undertaken with institutional Ethics Board approval in a private hospital in Barcelona, Spain. Indicated patients were WHO obesity class I-II, or III, where patients refused a surgical approach. RESULTS Between February 28, 2011 and March 23, 2012, the POSE procedure was successfully performed in 45 patients: 75.6 % female; mean age 43.4 ± 9.2 SD (range 21.0-64.0). At baseline: mean absolute weight (AW, kg), 100.8 ± 12.9 (75.5-132.5); body mass index (BMI, kg/m(2)), 36.7 ± 3.8 (28.1-46.6). A mean 8.2 suture-anchor plications were placed in the fundus, 3.0 along the distal body wall. Mean operative time, 69.2 ± 26.6 min (32.0-126.0); patients were discharged in <24 h. Six-month mean AW was 87.0 ± 10.3 (68.0-111.5); BMI decreased 5.8 to 31.3 ± 3.3 (25.1-38.6) (p < 0.001); EWL was 49.4 %; TBWL, 15.5 %. No mortality or operative morbidity. Minor postoperative side effects resolved with treatment by discharge. Patients reported less hunger and earlier satiety post procedure. Liquid intake began 12 h post procedure with full solids by 6 weeks. CONCLUSIONS At 6-month follow-up of a prospective case series, the POSE procedure appeared to provide safe and effective weight loss without the scarring, pain, and recovery issues of open and laparoscopic bariatric surgery. Long-term follow-up and further study are required.

Abstract
BACKGROUND Weight recidivism after Roux-en-Y gastric bypass (RYGB) is a challenging problem for patients and bariatric surgeons alike. Traditional operative strategies to combat weight regain are technically challenging and associated with a high morbidity rate. Endoluminal interventions are thus an attractive alternative that may offer a good combination of results coupled with lower periprocedure risk that might one day provide a solution to this increasingly prevalent problem. The purpose of this article is to systematically review the available literature on endoluminal procedures used to address weight regain after RYGB, with specific attention to the safety profile, efficacy, cost, and current availability. This review focuses only on endoluminal procedures that are performed for weight regain after RYGB, as opposed to primary endoluminal obesity procedures. METHODS This study was a retrospective review. RESULTS Several methods of endoluminal intervention for weight regain are reviewed, ranging from injection of inert substances to suturing and clipping devices. The literature review shows the procedures on the whole to be well tolerated with limited efficacy. The majority of the literature is limited to small case series. Most of the reviewed devices are no longer commercially available. CONCLUSIONS Endoluminal therapy represents an intriguing strategy for weight regain after RYGB. However, the current and future technologies must be rigorously studied and improved such that they offer durable, repeatable, cost-effective solutions.

Abstract
Obesity affects more than one third of adults in the United States and is associated with increased morbidity, mortality, and health care costs compared with normal weight adults. Current therapies include medical management consisting of therapeutic lifestyle change and pharmacotherapy, which has limited effectiveness, and bariatric surgery, which is currently the most effective therapy, but is limited by complications, long-term weight regain, and limited access. Endoscopic therapies are currently under investigation to treat weight regain after bariatric surgery and as a primary treatment for obesity, addressing the current gap in the treatment of obesity.

Abstract
The maintenance of the restrictive component of the Fobi pouch gastric bypass is essential for permanent weight control. Dilatation of the pouch-outlet and of the pouch itself is responsible for substantial weight gain by an increased volume per meal and binge-eating due to the rapid emptying. An endoscopic over-the-scope clip (OTSC®; Ovesco AG, Tübingen, Germany) was applied in 94 patients following gastric bypass and unintended weight gain by dilated gastro-jejunostomy to narrow the pouch-outlet. The OTSC®-clip application was safe and efficient to reduce the pouch-outlet in all cases. Best clinical results were obtained by narrowing the gastro-jejunostomy by placing two clips at opposite sites, hence reducing the outlet of more than 80%. Preferably, the clip approximated the whole thickness of the wall to avoid further dilatation of the anastomosis. Between surgery and OTSC®-clip application the mean BMI dropped from 45.8 (±3.6) to 32.8 (±1.9). At the first follow-up about 3 months (mean 118 days, ±46 days) after OTSC®-clip application the mean BMI was 29.7 (±1.8). At the second follow-up about 1 year (mean 352 days, ±66 days) after OTSC®-clip application the mean BMI was 27.4 (±3.8). The OTSC®-clip for revisional endoscopy after gastric bypass is reliable and effective in treating weight gain due to a dilated pouch-outlet with favorable short- and midterm results.

Abstract
Obesity and its associated conditions, including type 2 diabetes and cardiovascular disease, have reached epidemic proportions. Gastrointestinal weight loss surgery (GIWLS) shows the most promise in achieving significant and sustained weight loss and diabetes resolution. However, a large mismatch exists between the magnitude of the obesity epidemic and the number of surgical procedures performed to produce a significant shift in the distribution of obesity on a population level. This mismatch is fueled by high surgical costs, morbidity and mortality associated with surgical interventions, and the fact that the greatest public health burden of obesity comes from those around the center of the population body mass index distribution with mild to moderate obesity, rather than those at the distribution tail with severe obesity that GIWLS targets. New endoscopic methods, capitalizing on advances in our understanding of the physiological mechanisms by which GIWLS works, are developing to provide viable alternatives in the treatment of bariatric surgical complications, and for the primary treatment of obesity. These methods may have the added advantage of reduced invasiveness, reversibility, cost-effectiveness, and applicability to a larger segment of the population with moderate obesity.

Abstract
BACKGROUND Significant weight regain occurs for 10% to 20% of patients after Roux-en-Y gastric bypass (RYGB). Potential causative factors include anatomic abnormalities such as enlargement of the gastric pouch and gastrojejunostomy (GJ). This report describes endoscopic findings for patients referred for investigation of weight regain and presents the outcomes of revisional therapy for patients with abnormal anatomy. METHODS To evaluate gastric pouch and stoma size, RYGB patients referred for weight regain underwent upper endoscopy. A GJ was defined as enlarged if it had a diameter greater than 2 cm in any dimension, and a pouch was defined as enlarged if its length exceeded 6 cm long or its width exceeded 5 cm. Patients with abnormal anatomy who subsequently underwent revisional procedures were arbitrarily categorized into three groups based on the interval from RYGB to endoscopic evaluation: less than 5 years (group 1), 5 to 10 years (group 2), longer than 10 years (group 3). The percentage of regained weight lost (%RWL) after revision was compared between the groups. RESULTS In this study, 205 RYGB patients (176 women with a mean age of 47 ± 10 years and a current body mass index [BMI] of 43.4 ± 8.4 kg/m(2)) were evaluated. The mean time from primary RYGB was 6.9 ± 3.7 years, and the increase in BMI from its nadir was 9.78 ± 5.80 kg/m(2). Abnormal endoscopic findings (n = 146, 71.2%) included large GJ (n = 86, 58.9%), large pouch (n = 42, 28.8%), or both (n = 18, 12.3%). Of the 205 patients, 51 (24.9%) underwent a revisional surgical or endoluminal procedure. At a mean follow-up assessment 13 months after revision, group 1 (n = 12) had a mean %RWL of 103% ± 89.3%, and 62% of these patients lost all their regained weight. The mean %RWL was 45% ± 12.6% in group 2 (n = 30) and 40% ± 13.6% in group 3 (n = 9). CONCLUSION Endoscopy is a valuable tool for evaluating weight regain after bariatric surgery that can identify abnormal post-RYGB anatomy in a majority of patients. Revisional procedures to restore normal RYGB anatomy appear to be most successful if performed within 5 years after the primary procedure.

Stoma size critical to 12-month outcomes in endoscopic suturing for gastric bypass repair. Surg Obes Relat Dis 2011; 8:282-7.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is the most frequently performed bariatric procedure. However, weight regain after RYGB is common and often associated with pouch and stoma dilation. Historically, revision surgery has a greater risk of morbidity and mortality than the primary procedure. Endoscopic repair appears to be a safer option; however, current knowledge is limited regarding the longer term outcomes. Our objective was to prospectively collect the 12-month post-RYGB outcomes data after repair of dilated gastric tissue with an incisionless tissue approximation system in an open-label, single-group study at 9 U.S. sites. METHODS Adults ≥ 2 years after RYGB, with weight regain and pouch and/or stoma dilation underwent tissue plication with an endolumenal anchoring system to tighten dilated gastric tissue. The outcomes were captured, with statistical modeling used to identify the predictors of success. RESULTS Of the 116 subjects, 112 (97%) had anchors successfully placed (mean 5.9 anchors/subject). The mean stoma diameter and pouch length after the procedure was 11.5 mm (50% reduction) and 3.3 cm (44% reduction), respectively. At 12 months after repair (n = 73), the mean weight loss and percentage of excess weight loss was 5.9 ± 1.1 kg and 14.5% ± 3.1%, respectively. Anchor presence was confirmed endoscopically in 61 (92%) of 66 patients at 1 year. Those with a dilated stoma (>12 mm) who had a postrepair diameter of <10 mm (n = 22, 30% of 66) had more than double the excess weight loss compared with the rest of the cohort (24% versus 10%, P = .03). No serious adverse events occurred. CONCLUSION The 12-month outcomes have demonstrated the safety and durability of this method of gastric bypass repair. Aggressive reduction of stoma dilation was associated with superior weight loss.

Abstract
The primary role of endoscopic intervention in the care of bariatric surgery patients is in the management of late bariatric surgical complications and non-operative revision of the surgical anatomy. In the future, indications for therapeutic endoscopy will involve the gastroenterologist in primary weight loss interventions as cutting edge technology is currently undergoing rigorous scientific evaluation. Endoscopists caring for these patients should become familiar with post-bariatric surgical anatomy, potential complications, common presenting symptoms, anticipated luminal/extra-luminal findings, and endoscopic management of common bariatric complications; this review addresses these issues. This review will discuss common presenting symptoms, luminal as well as extra-luminal findings and endoscopic management of common bariatric complications.

Abstract
Endoscopic bariatric procedures are gaining traction as possible minimally invasive treatment modalities for obesity. This article focuses on the various endoscopic devices and procedures that pertain to primary and revisional treatments. Additionally, the article discusses the potential for applying these various devices and procedures to other points of intervention, including early intervention, bridge to surgery, and primary metabolic treatment (eg, diabetes management). Devices that are currently in human use are preferentially discussed, followed by references to devices that may see clinical use in the near future.

Abstract
BACKGROUND & AIMS Weight regain after Roux-en-Y gastric bypass (RYGB) is associated with reductions in health status and quality of life. We evaluated whether gastrojejunal stoma diameter is a risk factor for weight regain after RYGB. METHODS We examined data collected over 4 years from consecutive patients referred to a tertiary care bariatric center for upper endoscopy after RYGB. We used linear regression analysis to determine the association between the gastrojejunal stoma diameter and weight regain. We applied a logistic regression model using clinical and endoscopic parameters to develop a prediction rule for weight gain after RYGB. RESULTS Among 165 patients included in our study, 59% had significant weight regain (≥ 20% of maximum weight lost after the RYGB) and 41% did not. The mean percentage of maximal weight lost after RYGB that was regained in the entire cohort was 30% ± 22%. Gastrojejunal stoma diameter was associated significantly with weight regain after RYGB surgery in univariate analysis (β = .31, P < .0001). This association remained significant after adjusting for several known or purported risk factors for weight regain (β = .19, P = .003). We developed a simple prediction rule for weight regain after RYGB using a 7-point scoring system that includes the gastrojejunal stoma diameter, race, and percentage of maximal body weight lost after RYGB; a cut-off score of 4 or more points had an area under receiver operating characteristic curve of 0.76 and a positive predictive value of 75%. CONCLUSIONS Increased gastrojejunal stoma diameter is a risk factor for weight regain after RYGB and can be incorporated in a novel prediction rule.

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
In patients with severe gastroesophageal reflux disease post gastric bypass surgery, endoscopic plication with revision of the gastric pouch may be beneficial. Objective: A new technique for endoscopic plication and revision of the gastric pouch (EPRGP) for patients who underwent gastric bypass (RGB) surgery was evaluated in patients with severe GERD, dumping syndrome, failure of weight loss, or all of these. Patients and Methods: Patients underwent EPRGP over a 12-month period. The StomaphyX device (Endogastric Solutions, Redmond, WA) was utilized over a standard flexible gastroscope. Patients were kept on a liquid diet for 1 week. Results: The study included 64 patients with a mean age of 48 years who underwent 67 procedures. EPRGP was performed an average of 5 years after RGB. The mean preoperative BMI was 39.5 kg/m2. The primary indications for the procedure were inadequate weight loss, dumping syndrome (42), and GERD (15). The mean follow-up period was 5.8 months (range, 3 to 12). The average operative time was 50 minutes, with a significant reduction with increased operator experience. There were only 2 (3%) intraoperative complications during the early period (equipment failure), which did not result in any morbidity. All symptoms from dumping syndrome or reflux improved, with no further operative-related complications. The mean weight loss was 7.3kg. Conclusions: This study demonstrates the technical feasibility, safety, and efficacy of EPRGP.

Abstract
Laparoscopic gastric plication appears to add security to gastric band application and reduce the incidence of slippage after this procedure. Background: Laparoscopic insertion of a gastric band for weight reduction is increasingly performed in obese and morbidly obese patients. Complication rates after gastric band insertion are reduced by using certain techniques. Patients and Methods: This was a prospective study of all patients who underwent laparoscopic adjustable gastric band (LAGB) insertion at our unit. This procedure is performed through the classical 4-port technique and the use of a liver retractor. The pars flaccida method is performed in all patients, and the gold finger, a malleable instrument, is used to guide the band through the retroesophageal window in patients with difficult anatomy. Band slippage is avoided by using 2 types of gastric plication, depending on the anatomical characteristics of the stomach. Outcomes and morbidity are recorded, and patients are followed up in outpatient clinics. Results: Laparoscopic adjustable gastric band (LAGB) insertion was performed in 464 patients. A single consultant surgeon performed all procedures over a 2-year period. From August 2005 through August 2007, 380 (81.89%) women and 84 (18.10%) men were included in this study. The mean age was 41 years (range, 21 to 62). The mean body mass index was 43 (range, 35 to 62). Morbidity included dysphagia, epigastric pain, port displacement, port infection, erosion, and acute respiratory distress. Only one (0.21%) case of band slippage was reported. The mean follow-up was 26 months (range, 18 to 42). Conclusion: Laparoscopic gastric plication adds greater security and provides optimum gastric band placement. It is an effective method to reduce slippage after gastric band insertion.

Swain JM, Scott P, Nesset E, Sarr MG. All strictures are not alike: laparoscopic removal of nonadjustable Silastic bands after banded Roux-en-Y gastric bypass. Surg Obes Relat Dis 2010; 8:190-3. [PMID: 21130048 DOI: 10.1016/j.soard.2010.09.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2010] [Revised: 08/30/2010] [Accepted: 09/06/2010] [Indexed: 10/19/2022]
Abstract
BACKGROUND The concept of a nonadjustable Silastic band (NASB) has been used to promote surgically induced weight loss for >30 years. Vertical banded Roux-en-Y gastric bypass is an example. Some patients develop serious, band-related complications requiring treatment. Narrowing at the NASB will lead to refractory nausea, vomiting, regurgitation, and, even, malnutrition, requiring revision of their bariatric operation. We report on the evaluation, diagnosis, and laparoscopic treatment of proximal obstructive symptoms secondary to a NASB. METHODS From February 2005 to January 2009, we retrospectively reviewed the preoperative and perioperative data for 6 patients who had presented with proximal obstructive symptoms after undergoing banded Roux-en-Y gastric bypass. RESULTS The mean interval from primary NASB placement to surgery was 58 months (range 25-110). The mean duration of symptoms was 29 months (range 8-70). All patients presented with multiple symptoms, but all had nausea, vomiting, regurgitation, and dysphagia to liquids and solids. The patients had undergone multiple upper endoscopies (mean 4, range 3-6) and dilations (mean 1.3, range 1-2) without relief of their symptoms. All patients underwent successful laparoscopic removal of the NASB. Their mean hospital stay was 1 day (range 0-2). No operative or postoperative complications occurred. The reflux and obstructive symptoms had resolved immediately postoperatively in all patients. CONCLUSION Patients with a NASB in place can experience proximal obstructive symptoms. Endoscopy is deceptive in judging the stomal size, because the endoscope can be pushed through the band area. Moreover, endoscopic dilation will offer no benefit in most patients with symptomatic banded Roux-en-Y gastric bypass. Laparoscopic removal of the NASB is safe, relieves the symptoms immediately, and can be applied to patients who have undergone both open and laparoscopic Silastic banded bariatric procedures.

Incisionless revision of post-Roux-en-Y bypass stomal and pouch dilation: multicenter registry results. Surg Obes Relat Dis 2010; 6:290-5. [PMID: 20510293 DOI: 10.1016/j.soard.2009.12.011] [Citation(s) in RCA: 72] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2009] [Revised: 10/26/2009] [Accepted: 12/16/2009] [Indexed: 12/20/2022]
Abstract
BACKGROUND Surgical revision for weight regain after Roux-en-Y gastric bypass (RYGB) has been tempered by the high complication rates associated with standard approaches. Endoluminal revision of stoma and pouch dilation should intuitively confer a better risk profile. However, questions of clinical safety, durability, and weight loss need to be answered. We report our multicenter intraoperative experience and postoperative follow-up to date using the Incisionless Operating Platform for this patient subset. METHODS The patients who had regained significant weight >or=2 years after RYGB after losing >or=50% of excess body weight after RYGB were endoscopically screened for stomal and/or pouch dilation. Qualified patients underwent incisionless revision using the Incisionless Operating Platform to reduce the stoma and pouch size by placing anchors to create tissue plications. Data on the safety, intraoperative performance, postoperative weight loss, and anchor durability were recorded to date as a part of 2 years of postoperative follow-up. RESULTS A total of 116 consecutive patients were prospectively studied. Anchors were successfully placed in 112 (97%) of 116 patients, with an average intraoperative stoma diameter and pouch length reduction of 50% and 44%, respectively. The operating room time averaged 87 minutes. No significant complications occurred. At 6 months after the procedure (n = 96), an average of 32% of weight regain that had occurred after RYGB had been lost. The percentage of excess weight loss averaged 18%. The 12-month esophagogastroduodenoscopy results confirmed the presence of the anchors and durable tissue folds. CONCLUSIONS Incisionless revision of stoma and pouch dilation using the Incisionless Operating Platform can be performed safely. The data to date have demonstrated mild-to-moderate weight loss, and the early 12-month endoscopic images have confirmed anchor durability. Patients were actively followed up to document the long-term durability of this intervention in the entire patient subset.
