Abstract

The objective was to retrospectively analyze the dependence of long-term results of laparoscopic Roux-en-Y gastric bypass surgery according to the size of the formed gastric stumpMethods and materials. We retrospectively analyzed the long-term results of 207 morbidly obese patients who underwent laparoscopic Roux-en-Y gastric bypass surgery by two different techniques. The median follow-up was 36 months. Two groups of patients were identified according to the method of formation of the gastric stump: using 2 (1st group) or 3 (2nd group) stapler cassettes and performing of computed tomography volumetry to determine thevolume of the created gastric stump.Results. Statistically significant differences in the volume of the formed gastric stump, depending on the method of operation, were as follows: 23.8 ml (8.9–37.3 ml) in the 1st group and 47.7 ml (31.9–72.8 ml) in the 2nd group (p<0.0001). Significant differences were observed in the following indicators: relapse of weight gain or ...
