A Case of Laparoscopic Radical Resection after Neoadjuvant Chemotherapy for Sigmoid Colon Carcinoma with a Bladder Fistula

Abstract

A 68-year-old man was diagnosed as having advanced sigmoid colon cancer with a bladder fistula. Preoperative neoadjuvant chemotherapy was performed to avoid anterior pelvic evisceration. Since the tumor shrank, totally laparoscopic radical resection was performed. The bladder fistula was resected full-thickness, using bilateral observation with a laparoscope and a cystoscope, which resulted in negative margins. The pathological findings were adenocarcinoma, T4b, N0, M0, yStage IIc ; all surgical margins were negative. Preoperative chemotherapy made it possible to preserve bladder function, reduce operative stress, and achieve a complete resection. A successful case of conversion laparoscopic surgery for advanced sigmoid colon carcinoma with a bladder fistula is reported.
