Endoscopic hemorrhoidal band ligation is a well-established nonoperative method for treatment of bleeding internal hemorrhoids (grade 1 to 3). It is a safe and effective technique with a high success rate. Complications with this procedure are uncommon. Although rectal ulceration due to band ligation is a rare complication, it can cause life-threatening hemorrhage especially when patients are on medications which impair hemostasis like aspirin or non steroidal anti-inflammatory drugs. We present 2 cases of massive lower gastro-intestinal bleeding in patients who had a band ligation procedure performed 2 wk prior to the presentation and were on aspirin at home. Both the patients were hemodynamically unstable requiring resuscitation. They required platelet and blood transfusions and were found to have rectal ulcers on colonoscopy done subsequently. The rectal ulcers corresponded to the site of band ligation. The use of aspirin by these patients would have caused defects in the hemostasis and may have predisposed them to massive bleeding in the presence of rectal ulcers occurring after the band ligation procedure. Managing aspirin before and after the ligation may be difficult especially since adequate guidelines are unavailable. Stopping aspirin in all the cases might not be safe and the decision should be individualized.
Core tip: Rubber band ligation is known to be a relatively safe procedure. Massive bleeding and rectal ulceration is a very rare complication of this procedure. We came across two cases of severe, life-threatening lower gastrointestinal hemorrhage following endoscopic hemorrhoidal band ligation in patients on aspirin. The use of aspirin and other non-steroidal anti-inflammatory drugs can predispose to massive hemorrhage. The case report aims at creating awareness about these complications and that it may be advisable to avoid aspirin and non steroidal anti-inflammatory drugs immediately after band ligation.
