Colon interposition is a surgical procedure used for maintenance of luminal conduit after esophagectomy. Although epithelial neoplasia, such as adenoma and adenocarcinoma, may develop in the interposed colon, there are only few case reports on the condition. Due to the rarity of this condition, there is no definite consensus on recommending screening endoscopy for the early detection of neoplasia in the interposed colons. Here, we report a case of intramucosal adenocarcinoma in an interposed colon. Initial endoscopic resection for this tumor failed to accomplish complete resection. A subsequent endoscopic resection was performed 1 month later and complete resection was achieved. Based on our experience and recommendation on screening endoscopy for gastric cancer in Korea, we suggest that regular screening esophagogastroduodenoscopies should be performed following esophagectomy to detect early neoplasia in the stomach and interposed colon and avoid adverse results induced by delayed detection.
