Identifies risk factors for delayed perforation in patients undergoing endoscopic submucosal dissection, suggesting improvements in procedural training.

Key Points

The study aims to determine the incidence and risk factors of delayed perforation after endoscopic submucosal dissection for GISTs.
Retrospective identification of 57 cases with delayed perforation and 57 matched controls.
Collected baseline characteristics and timing of perforation.
Conducted univariate analysis and multivariate conditional logistic regression to identify risk factors.
57 patients experienced delayed perforation at a median of 2 days post-procedure.
Larger tumor size and operator inexperience were significant independent risk factors for delayed perforation.
Management strategies included endoscopic closure (31.6%), surgical repair (35.1%), and conservative treatment (33.3%), with a mean hospital stay of 7.5 days.
