Although gastroesophageal reflux disease is sometimes associated with esophageal ulcer and/or mucosal erosion, acute upper gastrointestinal bleeding from an esophageal ulcer is uncommon. We report a case of acute gastrointestinal bleeding from one of multiple esophageal ulcers in extensive Barrett's esophagus in the postoperative period after low anterior resection performed for descending colon carcinoma. A 74-year-old Japanese woman had undergone sigmoid colon resection 6 years earlier. The patient had a history of repeated reflux esophagitis. She was referred to a local hospital for a simple health screening 5 years after surgery. The patient had noticed bloody stool and felt mild difficulty at defecation 2 weeks before admission. Lower gastrointestinal endoscopy performed at a local hospital revealed a type 2 tumor located approximately 15 cm from the anal verge, which was obviously the cause of the bloody stool and constipation. The patient was admitted to our hospital for surgical treatment. Ten days after the low anterior resection, upper gastrointestinal bleeding occurred. Upper gastrointestinal endoscopy revealed multiple ulcers in the lower esophagus, which had caused the bleeding. Endoscopic biopsy revealed that esophageal ulcer occurred in the Barrett's esophagus, extending 15 cm from the functional esophagogastric junction. This case highlights acute upper gastrointestinal bleeding from multiple Barrett's ulcers in extensive Barrett's epithelium occurring in the postoperative period of colorectal carcinoma, and indicates an association of Barrett's esophagus with metachronous multiple colon carcinoma.
