A 24-year-old man presented to our hospital with rectal bleeding. Vital signs were stable and bloodwork revealed mild anemia. There was no contrast extravasation on computed tomography angiography of the abdomen and pelvis. Colonoscopy revealed blood pooling at the cecum with oozing from the appendiceal orifice. Using a transparent hood and suction, the appendix was everted as far as possible but the bleeding source could not be visualized. An emergent laparoscopic appendectomy was performed. Examination of the resected specimen revealed an ulcer with a visible vessel at the distal end of the appendix. The patient was discharged three days after the operation.
There are various etiologies of appendiceal bleeding and endoscopic hemostasis is often very challenging. In addition, there is high risk of subsequent appendicitis. As a result, all reported cases of appendiceal bleeding have received appendectomies either as the primary treatment or prophylactically after endoscopic hemostasis.
