Delayed post-polypectomy hemorrhage is a rare but serious complication.
Professor Jae Kwang Kim and colleagues from Korea identified risk factors for the development of delayed post-polypectomy hemorrhage.
The research team performed a retrospective case-control study of patients who developed delayed hematochezia after receiving colonoscopic polypectomy.
The control patients underwent uneventful polypectomy and were selected at a 4:1 ratio.

Of the 7447 lesions examined from the 3253 patients who received colonoscopic polypectomy, the team found that 53 lesions of 42 patients developed delayed hemorrhage, and 168 patients were selected as controls.
On further analysis, the researchers found that a polyp larger than 10 mm, a pedunculated polyp, and a polyp located in the right hemi-colon were significant risk factors for delayed post-polypectomy hemorrhage.
The team observed that the presence of comorbidities did not increase the risk of delayed hemorrhage.
Professor Kim's team commented, "Polyp size (large), shape (pedunculated), and location (right hemi-colon) represented substantial risk factors for the development of delayed hemorrhage after colonoscopic polypectomy."
