Laparoscopic Roux-en-Y gastric bypass in patients with body mass index >70 kg/m2

LRYGB is a technically feasible and safe surgical approach in the megaobese. The intraoperative blood loss was less with LRYGB than with ORYGB. The overall mortality and complications were not different, with the exception of hernia frequency, which was significantly greater after ORYGB. The percentage of excess body weight loss at 3 and 6 months was better for the LRYGB group. In both groups of patients, the 12- and 24-month excess body weight loss were similar.
