Objective To investigate the diagnosis and treatment of acute lower gastrointestinal bleeding. Methods The diagnosis and treatment of 21 cases of acute lower gastrointestinal bleeding were analyzed. Results In this group of 21 cases, 6 cases of hemostasis were successfully treated with drug, with a success rate of 2 8.6%. The positive rate of mesenteric artery angiography was 92.8%, and the success rate of interventional therapy was 84.6%. No recurrence was observed from 1 month to 4 years follow-up. Conclusions Acute upper gastrointestinal bleeding is the first choice of medication. Bleeding can not control the selection of selective mesenteric artery angiography. Angiography confirmed bleeding arteries involved in embolization at the same time. Negative contrast and hemorrhage can not control the surgical exploration
