Colorectal adenocarcinoma of the interposed colon after esophagectomy in infancy: a case report.

Colorectal carcinomas are a rare but possible complication in an interposed colonic segment used for reconstruction after esophagectomy. We report the case of a patient who underwent colonic interposition surgery in childhood due to esophageal atresia and was diagnosed with colorectal adenocarcinoma of the interposed colon ~57 years later. The patient underwent gastric pull-up after thoraco-abdominal resection of the colonic interposition en bloc with the adjacent remaining esophagus.
