Abstract

BACKGROUND:

The aim of this study was to perform an evidence-based analysis of the literature on open and laparoscopic surgery for morbid obesity.

METHODS:

Human studies on surgery for morbid obesity were conducted. Multiple publications of the same studies, abstracts, and case reports were reviewed. Current Contents, MEDLINE, EMBASE, and Cochrane Library databases were investigated.

RESULTS:

Open Roux-en-Y gastric by pass (RYGB) for morbidly obese patients and long-limb RYGB for superobese patients are highly effective procedures. Randomized controlled trials comparing malabsorptive procedures with other bariatric operations are needed. The long-term efficacy of adjustable silicone gastric banding (ASGB) still is undetermined because of poor evidence. Laparoscopic RYGB is as safe as its open counterpart, although its long-term results are lacking. Laparoscopic ASGB is less invasive than open ASGB, although its efficacy cannot be determined because of poor evidence. Laparoscopic vertical banded gastroplasty (VBG) is becoming unpopular since the decreasing trend of open VBG. Laparoscopic biliopancreatic diversion with duodenal switch is feasible, but needs further studies.

CONCLUSIONS:

Randomized controlled trials comparing the various laparoscopic operations are strongly needed.
