Purpose: Delayed hemorrhage rarely happens after a colonoscopic polypectomy, ranging from 0.2 to 1.8% in frequency. Although its occurrence is unpredictable and it may be serious in some cases, scanty data on its causes, characteristics, and effective management exist in Korea. This study was conducted to provide such data, especially data on the characteristics of delayed hemorrhage and its effective management.

Methods: From 1997 to 1999, one endoscopist at Song-Do Colorectal Hospital performed 5236 polypectomies on 2511 patients. Delayed hemorrhage occurred after 9 of those polypectomies, for a bleeding incidence rate of 0.17% (9/5236). The authors reviewed those 9 incidence of delayed hemorrhage, which involved 9 patients and 9 lesions, with emphasis on the characteristics of the bleeding and the treatment.

Results: The mean age of the 9 patients was 50 years, and the male-to-female ratio was 8:1. The sigmoid colon was involved in 4 of those patients (44.4%), and the right-sided colon was involved in another 4 of those patients. Lesions smaller than 11 mm were either sessile or flat-elevated and accounted for 6 of the 9 lesions (66.7%). The remaning lesions, which were larger than 10 mm, were either pedunculated or semipedunculated. Three (3) of the 9 patients (33.3%) experienced bleeding on day 1, the most common bleeding day. Another 5 patients (55.6%) experienced bleeding during the next 4 days (days 2 to 5). The last patient experienced bleeding on day 9, the latest bleeding day. A snare polypectomy had been performed on 7 of the 9 patients (77.8%), and a hot biopsy had been performed on the other 2 (22.2%). All delayed bleeding was treated by using hemoclips; additional epinephrine injection was used in 55.6% of the cases and an additional detachable snare in 22.2%. Rebleeding was noticed the day following the initial treatment of bleeding in one case and was managed by using hemoclips.

Conclusion: The first 5 days after a colonoscopic polypectomy are crucial, and caution is required during the next 5 days. Thorough knowledge about preventing and managing bleeding is essential.
