Bienzobas JR, et al. - Researchers undertook descriptive, observational, prospective study of patients undergoing gastroileal bypass with single anastomosis to demonstrate that this procedure is a safe and feasible procedure and results in outcomes comparable to the classic derivation, but with reduced surgical time with no decreased efficacy. They identified 1512 patients who underwent gastroileal bypass. The procedure was performed in a mean time of 32 min; the average stay was 2.2 days. Outcomes support that the procedure is safe and fast and provided results similar to biliopancreatic diversion with respect to weight loss.
