description Background Dumping syndrome (DS) is a common complication of bariatric surgery. Treatments include dietary and behavioral changes, as well as pharmacotherapy and revision surgery. All can be costly or hard to adhere to. In recent years, evidence accumulates in favor of endoscopic trans-oral outlet reduction (TORe) as an effective treatment for DS, targeting the pathophysiology of rapid gastric clearance. The objective of this study is to assess the safety and efficacy of TORe for DS in a single referral center. Methods Patients after bariatric surgery suffering DS were followed, and data were retrospectively analyzed. Diagnosis and post-procedural assessment of DS were made clinically using Sigstad score. During the procedure, the anastomotic rim was cauterized. Afterwards, 2 non-interrupted “8-figure” sutures were placed, resulting in imbrication of additional gastric tissue on top of the anastomosis and narrowing to

During the procedure, the anastomotic rim was cauterized. Afterwards, 2 non-interrupted “8-figure” sutures were placed, resulting in imbrication of additional gastric tissue on top of the anastomosis and narrowing to &lt;1 cm at the end of the procedure. Patients were instructed to keep a liquid diet for 14 days and follow-up continued for 6 months. Results Between 8/2018 and 9/2019 TORe was carried out in 13 patients (M:F = 3:10) with mean age of 45.1 (range 25–56) and BMI of 33.5 (range 28.1–40.3). Average time since recent surgery was 5.5 years (range 1–9). Mean pre-procedure anastomosis diameter was 25.2 mm (range 15–30) and was reduced to a mean of 5.6 mm (range 5–10). Three patients (23%) were admitted overnight due to inability to drink which resolved spontaneously. No major complications were reported. At 6 months, the Sigstad score was significantly reduced (19.4 ± 3.6 vs 5.2 ± 5.5, P  &lt; 0.001), and 11/13 (85%) of patients had a complete resolution of their dumping symptoms. In addition, BMI decreased by a mean of 2.3 kg/m 2 (−1 to 7.5, p  = 0.002). Conclusion TORe is a safe and effective treatment for patients suffering dumping syndrome and should be considered early in the treatment of DS.</description><identifier>ISSN: 0930-2794</identifier><identifier>EISSN: 1432-2218</identifier><identifier>DOI: 10.1007/s00464-020-08190-3</identifier><identifier>PMID: 33398583</identifier><language>eng</language><publisher>New York: Springer US</publisher><subject>Abdominal Surgery ; Bariatric Surgery - adverse effects ; Dumping syndrome ; Dumping Syndrome - etiology ; Endoscopy ; Gastric Bypass - adverse effects ; Gastroenterology ; Gastrointestinal surgery ; Gynecology ; Hepatology ; Humans ; Medicine ; Medicine &amp; Public Health ; Middle Aged ; Obesity, Morbid ; Proctology ; Retrospective Studies ; Surgery</subject><ispartof>Surgical endoscopy, 2021-12, Vol.35 (12), p.6846-6852</ispartof><rights>Springer Science+Business Media, LLC, part of Springer Nature 2021</rights><rights>2021.
