title: Adenocarcinoma in the jejunal pouch after proximal gastrectomy for early stage upper gastric cancer: report of a case.
abstract: An 84-year-old male was admitted to a local clinic suffering from general fatigue with associated anemia, and therefore was referred to our hospital. His medical history included a proximal gastrectomy with the formation of a jejunal pouch as a reconstructive treatment for early upper gastric cancer at 78 years of age (6 years prior). A type 2 tumor located in the jejunal pouch almost completely surrounded by small intestinal mucosa was demonstrated by gastrointestinal endoscopy. The biopsy specimens showed a moderately differentiated tubular adenocarcinoma. Computed tomography showed no lymphadenopathy or hepatic metastases. A resection of the residual stomach and jejunal pouch was performed. Based on the histological findings from the resected specimen, the tumor was considered to be primary adenocarcinoma in the jejunal pouch. The postoperative course was uneventful, and the patient has shown no evidence of any recurrence during the 6-year period after the most recent surgery.
