Abstract:
Background: Omega loop gastric bypass (OLGB) has been viewed with skepticism after the failure of the Bold 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.
