Laparoscopic Roux-en-Y Gastric Bypass Versus Laparoscopic Mini Gastric Bypass

NCT02601092 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 80

No results posted yet for this study

Summary

Several retrospective studies have shown same efficiency in regard to weight loss, with a lower rate of complications for the laparoscopic mini gastric bypass (LMGB) compared to Roux-en-Y gastric bypass (LRYGB). The aim of this double-blinded randomized controlled trial is to compare the two procedures in respect of excess weight loss, complications, operation time, length of stay and the metabolic impact on the hormonal brain-gut-axis.

PROCEDURE

Mini Gastric Bypass

The mini gastric bypass procedure was first developed by Dr Robert Rutledge from the USA in 1997, as a modification of the standard Billroth II procedure. A mini gastric bypass creates a long narrow tube of the stomach along its right border (the lesser curvature). A loop of the small gut is brought up and hooked to this tube at about 180 cm from the start of the intestine. No drugs or devices will be used.

PROCEDURE

Roux-en-Y Gastric Bypass

This variant is the most commonly employed gastric bypass technique, and is by far the most commonly performed bariatric procedure in the United States. The small intestine is divided approximately 45 cm (18 in) below the lower stomach outlet and is re-arranged into a Y-configuration, enabling outflow of food from the small upper stomach pouch via a "Roux limb". In the proximal version, the Y-intersection is formed near the upper (proximal) end of the small intestine. The Roux limb is constructed using 80-150 cm (31-59 in) of the small intestine, preserving the rest (and the majority) of it for absorbing nutrients. No drugs or devices will be used.
