Abstract

Background: Laparoscopic Roux-Y gastric bypass (LRYGBP) is the gold-standard procedure for the treatment of morbid obesity. It has been reported to be somewhat more efficient and durable than laparoscopic sleeve gastrectomy (LSG). However, it is considered more invasive and, therefore, more hazardous. There is a lack of unity in complication reporting following bariatric surgery. Thus, there is a possible misconception regarding the relative safety of the two major bariatric procedures performed worldwide. This may have contributed to a shift in practice with LSG gaining momentum “at the expense” of LRYGBP. The aim of this study was to evaluate the relative safety of primary LSG and LRYGBP according to the Clavien–Dindo complication grading system. Methods: A total of 2651 and 554 patients underwent primary LSG and LRYGBP, respectively at three high-volume centers. Thirty-day perioperative complications were recorded and graded. Length of hospital stays (LOS) and readmission rates were collected as well. Results: Complications occurred in 110 (3.7 %) and 24 (4.3 %) patients following LSG and LRYGBP, respectively (p = 0.9). No significant difference was found between the groups regarding overall and complication-grade-specific rates. Individual complication types were unevenly distributed, but not significantly so. Patients with complications were older than those without (47 and 43 years, respectively; p = 0.01). Gender was not a risk factor for complication. Median LOS and readmission rates were not significantly different. Conclusions: LSG and LRYGBP are equally safe, at least in the perioperative period. Acknowledging and conveying this finding to surgeons and patients alike is important and might cause a pendulum shift in the distribution of bariatric procedures performed.
