Abstract

Background

Omega loop gastric bypass (OLGB) has been viewed with skepticism after the failure of the “old Mason loop.” During the past 15 years, a growing number of authors worldwide approved that OLGB is a safe and effective procedure, which appears clearly from the operative outcome and long-term follow-up of consecutive cohort studies of patients who underwent OLGB. The aim of this study is to evaluate the outcomes of OLGB at the bariatric center of our university hospital between 2009 and 2015.

Methods

The data of 1520 patients who underwent OLGB from November 2009 to December 2015 at our center were reviewed. Mean age was 37.15 years, mean preoperative BMI was 46.8 ± 6.6 kg/m2, mean preoperative weight was 127.4 ± 25.3 kg, and 62.7% were women. Diabetes mellitus (DM) affected 683 (44.9%) of the 1520 patients, whereas 773 of the 1520 patients (50.9%) presented with hypertension. The mean operative time was 35 min.

Results

The 1-year postoperative BMI mean decreased to 29.6 ± 3.1 kg/m2, and at the 3-year follow-up, it was 27.5 ± 3.4 kg/m2. The mean of weight decreased to 81.3 ± 16.7 kg and to 78.9 ± 16.9 kg at the 1-year and the 3-year follow-up, respectively. Mortality rate was 0.1%. Overall complications were 9.3%; 0.8% required reoperations. Early complications were encountered in 50 patients (3.3%), and the late complications rate was (6.1%).

Conclusions

In this study, greater excess weight loss was observed with OLGB which appeared to be a short, simple, low-risk, effective, and durable bariatric procedure.
