Is laparoscopic sleeve gastrectomy a lower risk bariatric procedure compared with laparoscopic Roux-en-Y gastric bypass? A meta-analysis

摘要

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the current "gold standard" bariatric procedure in the United States. Laparoscopic sleeve gastrectomy (LSG) has recently become a commonly performed procedure for many reasons, including patients' perception that LSG has less complexity and invasiveness, and lower risk. Our objective was to review the literature and compare the leak rates, morbidity, and mortality for LRYGB versus LSG.
