Endoscopic treatment of rectovesical fistula after colorectal anastomosis: tube-in-tube endoscopic vacuum therapy method.

Abstract

A 56-year-old man underwent rectosigmoidectomy, partial cystectomy, and derivative colostomy for locally advanced distal rectal adenocarcinoma, persistent after chemoradiation. On the 25th postoperative day, he presented clinical worsening and increased abdominal drain output, and was submitted to tomography with intravesical contrast infusion, which showed a rectovesical fistula communicating with the surgical drain ([Fig. 1]).
