“…The adverse events most significantly related to patients' morbidity and mortality are bleeding and perforation. Reports have revealed the incidence of post-ESD bleeding to be 0% to 12% [3][4][5]. Although most cases can be managed endoscopically, post-ESD bleeding may result in surgery or the requirement for intensive care.…”

Background/Aims: Although second-look endoscopy (SLE) is frequently performed after gastric endoscopic submucosal dissection (ESD) to prevent bleeding, no studies have reported SLE findings after colorectal ESD. This study aimed to investigate SLE findings and their role in preventing delayed bleeding after colorectal ESD. Methods: Post-ESD ulcer appearances were divided into coagulation (with or without remnant minor vessels) and clip closure groups. SLE findings were categorized according to the Forrest classification (high-risk ulcer stigma [type I and IIa] and low-risk ulcer stigma [type IIb, IIc, III, or clip closure]), and risk factors for high-risk ulcer stigma were analyzed. Results: Among the 375 cases investigated, SLEs were performed in 171 (45.6%) patients. The incidences of high-risk ulcer stigma and low-risk stigma were 5.3% (9/171) and 94.7% (162/171), respectively. During SLE, endoscopic hemostasis was performed more frequently in the high-risk ulcer stigma group than in the lowrisk ulcer stigma group (44.4% [4/9] vs. 1.9% [3/162], respectively; p < 0.001), but most of the endoscopic hemostasis in the high-risk ulcer stigma group (3/4, 75.0%) were prophylactic hemostasis. Post-ESD delayed bleeding occurred in three (0.8%) patients belonging to the SLE group, of which, one patient was from the high-risk stigma group and two were from the low-risk stigma group. Conclusions: The incidence of high-risk ulcer stigma during SLE was low, and delayed bleeding occurred in, both, high-risk and low-risk groups of SLE. SLEs performed after colorectal ESD may not be effective in preventing delayed bleeding, and further prospective studies are needed to evaluate the efficacy of SLE in post-colorectal ESD.
