摘　　要：BACKGROUND Acute lower gastrointestinal bleeding(LGIB)is a common occurrence in clinical practice.However,appendiceal bleeding is an extremely rare condition that can easily be overlooked and misdiagnosed.The preoperative detection of appen-diceal bleeding often poses challenges due to the lack of related guidelines and consensus,resulting in controversial treatment approaches.CASE SUMMARY We presented a case of a 33-year-old female who complained of hematochezia that had lasted for 1 d.Colonoscopy revealed continuous bleeding in the appen-diceal orifice.A laparoscopic appendectomy was performed immediately,and a pulsating blood vessel was observed in the mesangium of the appendix,accor-dingly,active bleeding into the appendicular lumen was considered.Pathological examination revealed numerous hyperplastic vessels in the appendiceal mucosa and dilated capillary vessels.CONCLUSION The preoperative detection of appendiceal bleeding is often challenging,colo-noscopy is extremely important,bowel preparation is not routinely recommend-ed for patients with acute LGIB or only low-dose bowel preparation is recom-mended.Laparoscopic appendectomy is the most appropriate treatment for appendiceal bleeding.
