Laparoscopic sleeve gastrectomy versus Roux-en-Y gastric bypass for quality of life: a systematic review and meta-analysis.

Abstract

Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are the mainstays of bariatric surgery in recent years. In addition, there has been an increased interest in the quality of life (QoL) of obese patients after surgery. This study examined the QoL of patients who had undergone either LSG or LRYGB. We retrieved the literature from PubMed, Web of Science, Embase, and the Cochrane Library database before November 2019. A total of 10 articles and 2327 obese patients were included in our meta-analysis. The QoL scoring tools included in the statistical analysis are the following: the gastrointestinal quality of life index, 36-items short-form health survey, bariatric analysis and reporting outcome system, and the Moorehead-Ardelt quality of life questionnaire II. Although the QoL score of the LRYGB group was higher than that of the LSG group in the bariatric analysis and reporting outcome system subgroup, statistical analysis showed no difference in the postoperative QoL of LSG and LRYGB. In our study, no difference was found in the QoL between LSG and LRYGB. Therefore, in terms of postoperative QoL, surgical methods should be selected on the basis of the patients' condition and level of understanding of the surgeries.
