Abstract
PURPOSE: The use of laparoscopic sleeve gastrectomy (LSG) is increasing worldwide. Although post-LSG gastric stenosis (GS) is less frequent, it has not been well defined and lacks standardized management procedures. The objective of the present study was to describe a series of patients with GS symptoms after LSG and to develop a standardized management procedure for this complication. METHODS: We performed a retrospective analysis of a prospective database of patients presenting with GS after LSG procedures performed between January 2008 and March 2014. The primary efficacy criterion was the frequency of post-LSG GS. GS was classified as functional (i.e. a gastric twist) or organic. The secondary efficacy criteria included the time interval between LSG and diagnosis of GS, the type of stenosis, the type of management, and the follow-up data. RESULTS: During the study period, 1210 patients underwent primary or secondary LSG. Seventeen patients had post-operative symptoms of GS (1.4%); one patient had achalasia that had not been diagnosed preoperatively and thus was excluded from our analysis. The median time interval between LSG and diagnosis of GS was 47.2 days (1-114). Eleven patients had organic GS and six had functional GS. Seven patients required nutritional support. Endoscopic treatment was successful in 15 patients (88.2%) after balloon dilatation (n = 13) or insertion of a covered stent (n = 2). Two of the 15 patients required conversion to Roux-en-Y gastric bypass (11.8%). CONCLUSION: GS after LSG is a rare complication but requires standardized management. Most cases can be treated successfully with endoscopic balloon dilatation.
