{Abstract}: <B>OBJECTIVE: </B>Delayed bleeding (DB) is a major adverse event associated with colorectal endoscopic submucosal dissection (ESD) that sometimes causes difficulties in making decisions regarding endoscopic hemostasis. This study identified the factors that contribute to follow-up without endoscopic hemostasis when DB is suspected after colorectal ESD.<BR><B>METHODS: </B>In total, 583 patients (603 tumors) who underwent ESD or hybrid ESD for colorectal tumors at Chiba University Hospital between June 2009 and January 2022 were retrospectively registered. Of these, 141 cases (141 tumors) with DB; with hematochezia or hemoglobin decrease ≥2 g/dL after colorectal ESD were analyzed. The DB group was divided into the Hemostasis group (H group; endoscopic hemostasis performed) and no-Hemostasis group (no-H group; no endoscopy performed, or endoscopy performed but no hemostasis performed after hematochezia or hemoglobin decrease). Univariate and multivariate logistic regression analyses were performed to assess the factors contributing to follow-up.<BR><B>RESULTS: </B>Thirty-one patients with 31 tumors were categorized into the H group, while 110 patients with 110 tumors were in the no-H group. Multivariate regression analysis revealed that date from ESD to first hematochezia ≤Day 3 (odds ratio [OR] 4.55, 95% confidence interval [CI] 1.44-14.33; p = 0.010) and bleeding duration ≤1 day (OR 3.35, 95% CI 1.35-8.34; p = 0.009) contributed to follow-up.<BR><B>CONCLUSIONS: </B>In cases of DB after colorectal ESD, a bleeding duration ≤1 day or date from ESD to first hematochezia ≤Day 3 may contribute to follow-up observation without endoscopic hemostasis.
