Enhanced recovery after surgery (ERAS) in stoma reversal surgery: a systematic review and meta-analysis

Stoma reversal surgery is known for relatively high complication rates. While Enhanced Recovery After Surgery (ERAS) protocols are extensively validated for colorectal surgery, their use in stoma reversal remains underexplored. This systematic review and meta-analysis evaluates clinical outcomes of stoma reversal surgery under ERAS protocols compared to standard care (SC) practices. Medline, EMBASE, and Cochrane Central databases were searched for studies that compared clinical outcomes of stoma reversal surgery under ERAS protocols versus SC practices. The endpoints of interest were length of stay (LOS), ileus, wound infection, anastomotic leak, time to first stool, overall, minor, and major postoperative complications, readmission rates, and reoperation rates. Mean difference (MD) was calculated for continuous variables and Odds Ratio (OR) for dichotomous variables. Statistical analysis was performed with R version 4.4.0. We included eight studies comprising 1322 patients. Among these, 603 (45.6%) followed an ERAS protocol, while 719 (54.4%) received SC practices. ERAS was associated with a significant decrease in LOS (MD -1.83; 95% CI -2.55 to -1.12; p < 0.01), wound infection (OR 0.47; 95% CI 0.23 to 0.97; p = 0.041), and time to first stool (MD -1.02; 95% CI -1.22 to -0.81; p < 0.01). No statistically significant difference was observed regarding ileus, anastomotic leak, overall, minor, and major postoperative complications, readmission rates, or reoperation rates. The implementation of ERAS protocols in stoma reversal procedures should be considered, as it was associated with a shorter length of hospital stay without increasing morbidity, and may even reduce complications such as wound infections.
