Abstract
We report a rare case of a 77-year-old woman with adenocarcinoma in a colonic interposition following esophagectomy. She underwent esophagectomy and extra fistula of the remnant esophagus for corrosive esophagitis in 1982 and reconstruction by the left colon through subcutaneous route in 1985. In 2010 she presented with passage disturbance and endoscopy detected a type 1 tumor about 12 cm from the front teeth. The biopsy from this area yielded a diagnosis of adenocarcinoma. No lymph nodes or distant metastases were detected on CT and US. Based on a diagnosis of adenocarcinoma in a colonic interposition we performed partial resection of the colonic interposition. The postoperative course was good. Pathological findings were well differentiated adenocarcinoma (tub1) pMP (INFb) ly1 v0 pPM0 pDM0 pRM0.
