Modified transverse coloplasty pouch: new reconstruction techniques after total mesorectal excision. Our experience.

Abstract

The incidence of rectal cancer continues to rise. The functional results after complete Total Mesorectal Excision (TME) depend on the segment of colon used for reconstruction of colonic continuity and the form, the volume and the functional proprieties of the "neorectum". The aim of our study is evaluate the efficacy of our Modified Transverse Coloplasty Pouch (MTCP) after the treatment of low rectal cancer in terms of functional outcomes and quality of life. The study included 136 patients, underwent TME from January 2007 to December 2016 with diagnosis of extraperitoneal carcinoma of the rectum. The average distance of the tumor from the dentate line was 5.6 cm. Our follow-up protocol included functional outcome evaluation at 7th post-operative day (POD), 2nd month, and 6th month after the surgery. All patients (M/F 84/52) underwent anterior rectal resection (TME) with MTCP. Frequency of bowel movements per 24 hours in the studied patients compared at 7th POD, 2 months, and 6 months. Since the first post-operative weeks there is an encouraging reduction of the frequency of bowel movements. Modified Transverse Coloplasty Pouch (MTCP) had better functional results and quality of life compared to patients with a Colonic J Pouch (CJP) and traditional Transverse Coloplasty Pouch (TCP).
