Aim: To investigate the risk factors for delayed bleeding following endoscopic submucosal dissection (ESD) for colorectal neoplasms. Methods: We retrospectively reviewed the medical records of 991 consecutive patients who underwent ESD for colorectal neoplasms at our hospital from January 2007 to November 2016. Delayed post-ESD bleeding was defined as bleeding within 6 h to 30 days after ESD that resulted in either of the three situations: overt hematochezia, bleeding spots confirmed by repeat colonoscopy, or the requirement of a blood transfusion. Delayed bleeding was furtherly separated into early and late delayed bleeding by the end of post-ESD day 2. We analyzed the relationship between delayed bleeding and candidate factors including patient-, lesion-, and treatment-related details. Results: Delayed post-ESD bleeding was found in 47 patients (4.7%), of which 18 cases were late delayed bleeding. Among all patients, 14 patients required a second colonoscopy, and 2 other patients were transferred to surgery. Univariate analysis revealed that patients with hypertension (p = 0.017) and using hot biopsy forceps for wound management (p = 0.028) were significantly associated with late delayed bleeding. Both risk factors remained significant after multivariate analysis: hypertension (OR 2.829, 95% CI 1.101–7.265, p = 0.031), hot biopsy forceps (OR 2.873, 95% CI 1.013–8.147, p = 0.047). Using hot biopsy forceps was also the significant risk factor for late delayed bleeding compared with early delayed bleeding. Conclusion: Patient with hypertension and using hot biopsy forceps for wound management during procedure call for attention on high risk of delayed post-ESD bleeding. Therefore, additional perioperative treatment is recommended in patients with these risk factors. [ABSTRACT FROM AUTHOR]
