Laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy for the treatment of morbid obesity

Abstract

Background: bariatric surgery is the most effective treatment against morbid obesity. Among a variety of surgeries, Roux-en-Y gastric bypass (RYGBP) and sleeve gastrectomy (SG) are two of the mostfrequently performed. 
Objective: describe morbidity and effectiveness of RYGBP and SG in patients with body mass index (BMI) between 40 and 50 kg/m2.
Material and method: 782 SG and362 RYGBP with BMI between 40 and 50 kg/m2were included. Demographics, morbidity, mortality, need for reoperation, weight loss and resolution of comorbidities were evaluated.
Results: major morbidity was 1.67% for SG and 6.12% for RYGBP; early and late reinterventionsrate were 0.76% for SG and 3.6% for RYGBP. There was no mortality. Percentage of excess weight loss was (for SG and RYGBP respectively) 61.1% and 63.8 at 6 months, 67.9 and 76.9 at 1 year, 65.4 and 68.7 at 2 years and 63.2 and 71.2 at 3 years. Resolution of comorbidities was similar for both surgeries.
Conclusion: both SG and RYGBP were effective and safe for the treatment of morbid obesity and re- lated diseases.
