Adenocarcinoma of Transposed Colon: First Case of Synchronous Tumor

The surgical and anatomical basis for using the colon as a substitute for the esophagus were established in 1911 by Kelling and Vuillet1 and for many years was the technique of choice for esophageal replacement2. Its use is helpful in benign diseases, such as caustic or peptic strictures, and malignancies1,3, especially when the stomach cannot be used, and also in children with congenital anomalies2,4. However, this procedure is subject to early complications, as ischemia of the colon and leakage5, or late problems as anastomosis stenosis, ischemic colitis, fistula due to diverticulitis and malignant lesions4. The transposed colon cancer is a rare complication. Since 2007, six new cases were reported and two reviews published. Hwang et al6 found 10 reported cases of adenocarcinoma in the transposed colon and Bando et al7 also reviewed 10 cases in the literature, encompassing adenomas and adenocarcinomas. The aim is to report an unique case of synchronous adenocarcinoma of the transposed colon.
