Outcomes of same-day discharge sleeve gastrectomy and Roux-en-Y gastric bypass: a systematic review and meta-analysis.

Abstract

Length of stay after bariatric surgery has progressively shortened. Same-day discharge (SDD) has been reported for the 2 most common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). The aim of this study is to evaluate the safety and success of SDD following SG and RYGB. Systematic literature search on SDD after bariatric surgery was conducted in Medline, Cochrane library, Google Scholar, and Embase. SDD was defined as discharging the patient during the day of the bariatric operation, without an overnight stay. The primary outcomes of interest were successful SDD, readmission, and morbidity rates. The secondary endpoints included reoperation and mortality rates. A proportion meta-analysis was performed to assess the outcomes of interest. A total of 14 studies with 33,403 patients who underwent SDD SG (32,165) or RYGB (1238) were included in the qualitative synthesis. Seven studies with 5000 patients who underwent SDD SG were included in the quantitative analysis, and pooled proportions (PPs) were calculated for the outcomes of interest. The SDD success rate was 63%-100% (PP: 99%) after SG and 88%-98.1% after RYGB. The readmission rate ranged from .6% to 20.8% (PP: 4%) after SDD SG and 2.4%-4% after SDD RYGB. Overall morbidity, reoperation, and mortality were 1.1%-10% (PP:4%), .3%-2.1% (PP: 1%), and 0%-.1% (PP: 0%), respectively, for SDD SG, and 2.5%-4%,1.9%-2.5%, and 0%-.9%, respectively, for SDD RYGB. SDD after SG seems feasible and safe. The outcomes of SDDRYGB seem promising, but the evidenceis stilllimitedto draw definitive conclusions. Selection criteria and perioperative protocolsmust be standardized to adequately introduce this practice.
