Acute lower gastrointestinal hemorrhage associated with the appendix is rare. We report on a 42-year-old male patient who presented with hematochezia from solitary appendiceal bleeding. The patient was admitted to our hospital with rectal bleeding, and abdominal computed tomography identified active contrast leakage in the distal portion of the appendix. During a subsequent urgent colonoscopy, active bleeding in the appendiceal orifice was identified. The patient was successfully treated with a laparoscopic appendectomy and hematochezia did not recur postoperatively. Microscopic examination revealed an eroded appendiceal mucosa, focal inflammatory infiltrates, and a normal submucosal vessel without evidence of vascular malformation.
与阑尾相关的急性下消化道出血很罕见。我们报告一例42岁男性患者，因阑尾孤立性出血出现便血。该患者因直肠出血入院，腹部计算机断层扫描发现阑尾远端有造影剂外渗。在随后的紧急结肠镜检查中，发现阑尾开口处有活动性出血。患者通过腹腔镜阑尾切除术成功治愈，术后便血未复发。显微镜检查显示阑尾黏膜糜烂、局灶性炎症浸润，黏膜下血管正常，无血管畸形证据。
