Study identified risk factors for intraoperative and delayed perforations in gastric endoscopic submucosal dissection for early gastric cancer. Intraoperative perforation occurred in 2.2% of patients, necessitating emergency surgery in 0.04% of cases, while delayed perforation occurred in 0.4% of patients, with emergency surgery required in 0.12% of cases. Factors like location in upper or middle third of the stomach, remnant stomach or gastric tube, procedure time ≥100 min, tumor size >35 mm, and BMI <18.5 kg/m were significantly correlated with intraoperative perforation.
