In particular, delayed bleeding that occurs after the seventh postoperative day is rare.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Case presentation<\/jats:title>\n<jats:p>A 54-year-old man underwent laparoscopic distal gastrectomy, D2 lymph node dissection, and Roux en-Y reconstruction for duodenal neuroendocrine tumors. Drainage was performed for a postoperative pancreatic fistula and abdominal abscess. On the 28th postoperative day, he passed a large amount of bloody stool; therefore, emergency esophagogastroduodenoscopy (EGD) and angiography were performed. However, neither examination demonstrated any bleeding foci or pseudoaneurysm. He was conservatively observed and discharged on the 50th postoperative day. Approximately 1 year after the surgery, he passed a bloody stool and experienced hemorrhagic shock. An EGD revealed exposed blood vessels at the duodenal blind end. His condition was diagnosed as a pseudoaneurysm arising from gastroduodenal artery, which ruptured into the duodenum, based on abdominal contrast-enhanced computed tomography findings. Emergency angiography was performed, and the pseudoaneurysm and artery were successfully embolized.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>This case illustrates that there is a possibility of delayed bleeding even 1 year after gastrectomy.
