NCT04357119

Brief Summary

Evaluation of the effect of the common limb length on the outcome of laparoscopic single anastomosis gastric bypass in morbidly obese patients. Two groups of patients: one group with a common limb length of about 200 cm distal to the ligament of Treitz and the second group with a common limb length of 300 cm proximal to the ileocecal valve. Groups are evaluated regarding percentage of excess weight loss, resolution of comorbidities, and long term complications.

Study Arms (2)

CL measured from Treitz ligament

ACTIVE COMPARATOR

A 14-16 cm long gastric tube is created using a 60 mm stapler starting on the lesser curvature at the crow's foot level. It is tailored following the edge of a 38F calibrating orogastric tube up to the angle of His. A loop gastroenterostomy is then created with the small bowel about 200 cm distal to the ligament of Treitz with the same stapler using a 60 mm blue cartridge

Procedure: One-anastomosis gastric bypass

CL measured from ileocecal valve

Interventions

Laparoscopic single anastomosis gastric bypass is reported to be a safe alternative to LRYGB, showing comparable efficacy in weight reduction and resolution of metabolic complications with reduced surgical complications. The advantages with this technique as claimed by those speaking in favor of it are many: fewer sites for leakage and internal hernia, easier and faster to learn and perform, easy to reverse and revise, and with results at least comparable with the result following standard Roux-en-Y gastric bypass (RYGB). The length of the biliopancreatic limb in single anastomosis gastric bypass as reported by Rutledge is fixed 200 cm starting at the duodenojejunal junction, neglecting the length of the common limb. Because of deficient data regarding the effect of common limb length on the outcome of LSAGB, so a clinical trial shall add new knowledge regarding sufficient weight loss, rate of complications and the need for revision.
