## Abstract

Hemobezoar is a rare cause of intestinal obstruction after mini gastric bypass/one anastomosis gastric bypass. Clot formation is often caused by bleeding in the anastomotic staple line. Symptoms include abdominal pain, vomiting, and abdominal distension. Surgical treatment should be performed promptly to prevent serious complications, such as anastomotic leaks, intestinal perforation, and death. Intraoperative endoscopy is useful for examining intraluminal mucosa and identifying the cause of the obstruction. This report describes a case of hemobezoar in a male patient. Few cases of hemobezoar have been reported in the literature.
