Core Tip
Core Tip: Stoma reversal is frequently perceived as a minor elective procedure, yet it carries a significant risk of postoperative morbidity. In this prospective study, advanced age and longer anastomosis time emerged as the strongest predictors of clinically significant (Clavien-Dindo grade ≥ II) complications, postoperative ileus, and prolonged hospital stay, whereas type of stoma and anastomotic technique were not independent risk factors. These findings emphasize that stoma reversal should be approached as a major abdominal operation, with careful patient selection, preoperative optimization, and operative strategies aimed at minimizing anastomosis time to improve outcomes.
