Comparison of the results of laparoscopic mini-gastric bypass with various the gastric pouch size: randomized clinical trial

The aim of this study was to compare the results of mini-gastric bypass surgery with different lengths and widths of the gastric pouch. Methods. The author conducted a prospective clinical study with a random distribution of patients into comparison groups. The study included 500 patients who underwent laparoscopic mini-gastric bypass surgery - one anastomosis gastric bypass (MGB-OAGB). The first group included 248 patients, where the standard Carbajo MGB-OAGB technique with a long and wide gastric pouch was used. And in the second group there were 252 patients, where a shortened and narrower small stomach was created. Results. The second group showed a more pronounced bariatric effect compared to the first group. After surgery, the change in body mass index in the second group was 16.1±5.7 kg / m2 compared to 12.4±3.08 kg / m2 in the first group (p
