Abstract
An 81-year-old man was admitted with a diagnosis of esophageal cancer with left bronchial invasion. He was treated with combination chemotherapy (5-FU + CDDP) on March 14, 2012. Sudden onset abdominal pain and nausea appeared on June 13, 2012. Abdominal CT showed wall thickening of the descending colon with free air and ascites. He underwent emergency surgery under a diagnosis of panperitonitis due to descending colon perforation. Intraoperatively, a 25-mm-diameter perforation was found in the descending colon. The patient required a partial resection of the descending colon and a transverse colostomy. On pathology, spontaneous perforation without specific inflammation or metastasis was diagnosed. The postoperative course was uneventful, and he was discharged on day 23 after surgery.
