Abstract

Abstract: Objective: Endoscopic submucosal dissection (ESD) is now commonly performed as a treatment for not only gastric tumor but also colorectal tumor. However, colorectal ESD has a substantial risk of complications, including post-ESD electrocoagulation syndrome, bowel perforation and bleeding. This study aimed to investigate whether prophylactic endoscopic closure can reduce the occurrence of complications after colorectal ESD. Materials and methods: Patients who underwent colorectal ESD in our unit were randomly assigned to either of two groups. Prophylactic endoscopic closure for an artificial ulceration after ESD was performed in group I but not in group II. After the procedure, the incidence of complications, visual analog scale (VAS) score for abdominal pain, and laboratory findings were investigated. Results: Of the 220 patients (110 per group) enrolled in this study, 137 were men. No significant differences were found in age, sex, comorbidity, medication history, tumor location, size of resected specimen, and pathologic result between the two groups. No significant difference was found in ESD outcomes, including hospitalization period, laboratory findings, VAS score for abdominal pain, incidence of surgical operation, and incidence of post-ESD complications, between the two groups. Conclusions: Contrary to popular belief, prophylactic endoscopic closure after colorectal ESD does not decrease the incidence of complications, and it does not ameliorate inflammatory response and abdominal pain.
