Gastric stenosis (GS) is a potential adverse event post-laparoscopic sleeve gastrectomy (LSG). Endoscopic management is preferred; however, there is significant variation in therapeutic strategies with no defined algorithm. This study aims to describe the safety and efficacy of a predefined step-wise algorithm for endoscopic management of GS post-LSG.


Consecutive patients with symptomatic GS post-LSG, presenting between July 2015 and August 2016, were subjected to a predefined treatment algorithm of serial dilations using achalasia balloons, followed by a fully covered self-expanding metal stent (FCSEMS) if dilations were inadequate. Patients who did not respond or opted out of ongoing endoscopic therapy were offered revision Roux-en-Y gastric bypass (RYGB).


Total of 17 patients underwent a median of 2 (range 1–4) balloon dilations. Twelve patients (70.6%) reported clinical improvement with balloon dilation alone, while 3 (17.6%) required subsequent FCSEMS placement. One patient suffered a tear to the muscularis propria with balloon dilation, which was managed conservatively. Overall, 15 (88.2%) reported clinical improvement with endoscopic management. PAGI-SYM scores revealed that the strongest response to therapy, based on mean reduction of score ± SD, was in the following items: nausea (3 ± 1.9, P < 0.001), heartburn during day (2.8 ± 1.5, P = 0.003), heartburn on lying down (3.4 ± 1.4, P < 0.001), reflux during day (2.8 ± 1.9, P < 0.001), and reflux on lying down (3.0 ± 1.9, P < 0.001). Two (11.8%) patients failed endoscopic therapy and underwent RYGB.


Endoscopic management of GS using the described algorithmic approach is safe and effective post-LSG. Patients with severe stenosis or helical stenosis are likely to require revision RYGB.

Initial endoscope being advanced through the gastro-esophageal junction with healed staple line visible to the left leading to the site of stenosis (0:10). Endoscope passed through stenotic segment and into the fourth part of duodenum. Savary Guidewire (Cook Medical, Boomington, Indiana) being introduced through the scope into the fourth part of the duodenum (0:30). Inspecting the deflated achalasia balloon (0:50). Achalasia balloon (Rigiflex™ II Single-Use Achalasia Balloon Dilators, Boston Scientific, Natick, MA, USA) being inserted over the wire, situated with the middle of the balloon across the stenotic segment (1:06). Balloon inflated to 20 psi pneumatic pressure which is maintained for 1 min. There is visible relative tissue ischemia at the site of the stenosis (1:24). Balloon deflated and withdrawn followed by re-inspection of stenosis segment (2:00). (MP4 232,436 kb)
