Endoscopic Dilation of Bariatric RNY Anastomotic Strictures: a Systematic Review and Meta-analysis
Obesity Surgery, 2018
Gastrojejunostomy anastomotic strictures are a complication of Roux-en-Y gastric bypass surgery without an established treatment guideline. A systematic review and meta-analysis were performed to determine the safety and efficacy of endoscopic dilation in their management. PubMed, Web of Science, and Cochrane Central (1994-2017) were searched. Data was analyzed with random effects meta-analysis and mixed effects meta-regression. Twenty-one observational studies (896 patients) were included. The stricture rate for laparoscopic patients was 6% (95% CI, 5-9%). Only 38% (95% CI, 30-47%) required greater than one dilation. Symptom improvement occurred in 97% (95% CI, 94-98%). The complication rate was 4% (95% CI, 3-6%). Endoscopic dilation of GJA strictures is safe, effective, and sustaining. This study can guide endoscopists in the treatment of a common bariatric surgical complication.

Background The optimal operative technique in gastric bypass (RYGB) is still under debate. We have studied patient-reported gastrointestinal symptoms and weight loss 5 years after RYGB performed with three different stapling techniques for the gastrojejunal anastomosis (GJ). Methods Out of 593 patients operated with RYGB, 489 patients [80.2 % women, body mass index (BMI) 44.9 (33-68) kg/m 2 ] answered our 5-year follow-up questionnaire concerning gastrointestinal symptoms (vomiting, reflux, dumping, abdominal pain or diarrhea), weight loss, need for postoperative endoscopic interventions and overall satisfaction with the procedure. We compared the results for three different GJ techniques: linear stapler (LS, n = 103), 21-mm circular stapler (C21, n = 88) and 25-mm circular stapler (C25, n = 298). Results Dumping was the most commonly reported symptom (14.1 % of all patients on a weekly to daily basis), however, less frequently reported in the C25 group (p \ 0.05). Vomiting, prevalent in 2.9 % of all patients, was more frequently reported in the C21 group (p \ 0.01). No group consistently showed greater weight loss compared to the other two groups. A higher incidence of endoscopic dilatations due to strictures was reported in the C21 group (12.5 % compared to 4.5 % of all patients, p \ 0.05). Overall patient satisfaction was high (88 %). Conclusion Our data suggest that the technique for the construction of the GJ in RYGB affects gastrointestinal symptoms 5 years postoperatively. The difference is moderate but indicates that a narrow GJ results in increased frequency of vomiting and need for endoscopic interventions without improving the weight result.
The cooperation between endoscopists and surgeons in treating complications of bariatric surgery
Best Practice & Research in Clinical Gastroenterology, 2014
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 comorbidities. 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.

Background Both weight regain and dumping syndrome (DS) after Roux-en-Y gastric bypass (RYGB) have been related to the dilation of gastro-jejunal anastomosis. The aim of this study is to assess the safety and long-term efficacy of endoscopic transoral outlet reduction (TORe) for DS and/or weight regain after RYBG. Materials and Methods A retrospective analysis was performed on a prospective database. Sigstad’s score, early and late Arts Dumping Score (ADS) questionnaires, absolute weight loss (AWL), percentage of total body weight loss (%TBWL), and percentage of excess weight loss (%EWL) were assessed at baseline and at 6, 12, and 24 months after TORe. Results Eighty-seven patients (median age 46 years, 79% female) underwent TORe. The median baseline BMI was 36.2 kg/m2. Out of 87 patients, 58 were classified as “dumpers” due to Sigstad’s score ≥ 7. The resolution rate of DS (Sigstad’s score < 7) was 68.9%, 66.7%, and 57.2% at 6, 12, and 24 months after TORe, respectively. A signi...
Gastrojejunal strictures following laparoscopic Roux-en-Y gastric bypass for morbid obesity
Surgical Endoscopy, 2005
Background: Gastrojejunal strictures following laparoscopic Roux-en-Y gastric bypass (LRYGBP) present with dysphagia, nausea, and vomiting. Diagnosis is made by endoscopy and/or radiographic studies. Therapeutic options include endoscopic dilation and surgical revision. Methods: Of 369 LRYGBP performed, 19 patients developed anastomotic stricture (5.1%). One additional patient was referred from another facility. Pneumatic balloons were used for initial dilation in all patients. Savary-Gilliard bougies were used for some of the subsequent dilations. Results: Flexible endoscopy was diagnostic in all 20 patients allowing dilation in 18 (90%). Two patients did not undergo endoscopic dilation because of anastomotic obstruction and ulcer. The median time to stricture development was 32 days (range: 17-85). Most patients (78%) required more than two dilations. The complication rate was 1.6% (one case of microperforation). At a mean follow-up of 21 months, all patients were symptom-free. Conclusions: Gastrojejunostomy stricture following LRYGBP is associated with substantial morbidity and patient dissatisfaction. Based on our experience, we propose a clinical grading system and present our strategy for managing gastrojejunal strictures.
Size really does matter-role of gastrojejunostomy in postoperative weight loss
Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery
Although the published data have clearly related the size of the gastrojejunostomy anastomosis to the subsequent likelihood of a stricture, a correlation between the anastomosis size and postoperative weight loss has not previously been described. A retrospective comparison was made of 124 anastomoses accomplished with the 21-mm circular stapler followed by 100 anastomoses created with the 45-mm linear stapler technique at 6 community hospitals in Southern California. Age, gender, and preoperative weights were not significantly different between the 2 groups. The precise size of the anastomosis created using the linear stapler technique could not be determined, but it was calculated to be slightly larger than a 25-mm circular stapled anastomosis. Both weight loss trends were fit with a 1-phase exponential nonlinear regression analysis. The resulting curves were compared using an F test. A 1-tailed t test was also used to compare the weight loss at 12 months. An F test comparison of ...
Incidence and outcome of anastomotic stricture after laparoscopic gastric bypass
Journal of Gastrointestinal Surgery, 2003
Anastomotic stricture is a frequent complication after Roux-en-Y gastric bypass (GBP). We evaluated the frequency of anastomotic stricture following laparoscopic GBP using a 21 mm. vs. a 25 mm circular stapler for construction of the gastrojejunostomy and the safety and efficacy of endoscopic balloon dilation in the management of anastomotic stricture. We reviewed data on 29 patients in whom anastomotic strictures developed after laparoscopic GBP. All strictures were managed with endoscopic balloon dilation using an 18 mm balloon catheter under fluoroscopic guidance. Main outcome measures were the number of anastomotic strictures in patients in whom the 21 mm (vs. 25 mm) circular stapler was used to create the gastrojejunostomy, time interval between the primary operation and symptoms, complications of endoscopic balloon dilation, the number of patients with resolution of obstructive symptoms, and body weight loss. There were 28 females with a mean age of 39 years and a mean body mass index of 48 kg/ m2. Anastomotic stricture occurred significantly more frequently with the use of the 21 mm compared to the 25 mm circular stapler (26.8% vs. 8.8%, respectively; P<0.01). The median time interval between the primary operation and presentation of stricture was 46 days. After the initial dilation, recurrent stricture developed in 5 (17.2%) of 29 patients. These five patients underwent a second endoscopic dilation, and only one of these five patients required a third endoscopic dilation. None of the 29 patients required more than three endoscopic dilations. The mean percentage of excess body weight loss at 1 year for patients in whom the 21 mm circular stapler was used for creation of the gastrojejunostomy was similar to that for patients in whom the 25 mm circular stapler was used (68.2% vs. 70.2%, P = 0.8). In this series the rate of anastomotic stricture significantly decreased with the use of the 2 5 mm circular stapler for construction of the gastrojejunostomy without compromising weight loss. Endoscopic balloon dilation is a safe and effective option in the management of anastomotic stricture following laparoscopic GBP.

Background The duodenal-jejunal bypass sleeve (DJBS) has been shown to achieve a completely endoscopic duodenal exclusion without the need for stapling. This report is the first randomized controlled trial for weight loss. Methods In a 12-week, prospective, randomized study, subjects received either a low fat diet and the DJBS or a low fat diet control (no device). Twenty-five patients were implanted with the device and 14 received the control. The groups were demographically similar. Both groups received counseling at baseline only, which consisted of a low calorie diet, and exercise/behavior modification advice. No additional counseling occurred in either group. Measurements included starting and monthly body weight and serum blood tests. The device group also had a plain abdominal film post implant, a monthly KUB and a 4-week post explant EGD. Results Twenty device (80%) subjects maintained the DJBS without a significant adverse event for the 12-week duration. At 12 weeks, the mean excess weight loss was 22% and 5% for the device and control groups, respectively (p \ 0.001). Five subjects (20%) were endoscopically explanted early secondary to upper GI (UGI) bleeding (n = 3), anchor migration (n = 1) and sleeve obstruction (n = 1). The UGI bleeding occurred at a mean of 13.8 days post implant. EGD was performed in each of these cases with no distinct bleeding source identified. No blood transfusion was required. The migration occurred on day 47 and manifested as abdominal pain. The subject with the sleeve obstruction presented with abdominal pain and vomiting on day 30. Eight subjects (40%) underwent the 4 week post explant EGD at which time mild degrees of residual duodenal inflammation was noted. Conclusion The DJBS achieves noninvasive duodenal exclusion and short term weight loss efficacy. Longer term randomized controlled sham trials for weight loss and treatment of T2DM are underway.

One of the roles of the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) is to provide guidance on the management of patients seeking surgery for adiposity-based chronic diseases. The role of endoscopy around the time of endoscopy is an area of clinical controversy. In 2018, IFSO commissioned a task force to determine the role of endoscopy before and after surgery for the management of adiposity and adiposity-based chronic diseases. The following position statement is issued by the IFSO Endoscopy in Bariatric/Metabolic Surgery Taskforce. It has been approved by the IFSO Scientific Committee and Executive Board. This statement is based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence. It will be reviewed regularly.
