- Abstract
Endoscopic submucosal dissection (ESD) technique has facilitated en bloc removal of widely spread lesions from the stomach. This retrospective study aimed to determine factors associated with serious complications of ESD. Between December 2001 and March 2007, we have performed ESD for 478 lesions in 436 patients. We experienced 39 patients with post-operative bleeding and 17 patients with perforation. Risk factors of patients who received ESD in gastric mucosal tumors for complications were evaluated, focusing on resected size, location, scar lesions, operation time, and experience of endoscopists. We evaluated the patients’ background characteristics including sex, age, body mass index (kg/m2), drug history of anticoagulant, and underlying diseases including cerebrovascular disorder, ischemic heart disease, liver dysfunction, renal dysfunction, hyperuricemia, hypertension and diabetes mellitus. Multivariate analysis indicated a risk factor for perforation was long operation time. Multivariate analysis indicated a significant risk factor for post-operative bleeding was size of the resected tumor. This study indicated risk factors for serious complications of ESD. Large resected tumor size was a risk factor for post-operative bleeding, while long operation time was a risk factor for perforation. Information regarding operation risk factors should be useful for planning strategies for ESD.
