Obstruction of gastroenteroanastomiosis after laparoscopic gastr bypass in bariatric patients

Introduction. Obstruction of the gastroenteroanastomosis (GEA) is a complication specific to bariatric surgery, the tactics of combating which are not currently standardized, and the problem itself continues to be relevant and debatable.

The aim of the study was to study the features of the diagnosis and treatment of GEA obstruction after laparoscopic gastric bypass.

Materials and methods. A retrospective analysis of the results of 360 laparoscopic gastric bypasses performed at the FSCC FMBA of Russia for the period from 2019 to 2023 was carried out.

Results. In the early postoperative period, GEA obstruction developed in 6 patients (1.7%). In all cases, the complication was resolved conservatively within 3 to 6 days. In the long-term period, GEA obstruction was diagnosed in 9 patients (2.5%) within 28 to 74 days. In all cases, the complication was resolved by endoscopic bougienage and dilatation of the GEA. No one required surgical treatment.

Conclusions. GEA obstruction is a relatively rare complication of laparoscopic gastric bypass surgery, which can be effectively dealt with in a specialized center. If obstruction occurs in the immediate postoperative period, as a rule, conservative therapy is sufficient. With the development of GEA stricture in the long-term period, it is possible to achieve a satisfactory result using endoscopic techniques.
