Coloplasty for Neorectum Construction after Low Anterior Resection

Background: Low anterior resection is now considered the gold standard procedure for low and ultra low rectal cancer especially from oncological point of view. However straight colo-anal anastomosis is functionally cumbersome to the patients. The idea of colonic pouch hence was raised and proven to be effective in alleviating frequency and urgency associated with straight colo-anal anastomosis.Aim of Work: In this study our aim was to assess feasibility of coloplasty as a colonic pouch to replace the rectum.Patients and Method: Fifteen patients who had low anterior resection done were included in this study, transverse coloplasty pouch was done and functional outcomes were assessed by both clinical and manometric means.Results: Nine female and 6 males were included in this study, the mean operative time was 131min., and leakage rate was 6.66%. The mean number of motions per day was 3.17 and 1.67 at three and twelve months respectively. The grade of continence was 3.5 and 1.25 at three and twelve months. Manometric measures were 50.5mmHg for resting pressure, 126.993mmHg for squeeze pressure and 108.17ml for threshold volume.Conclusion: Coloplasty is a safe, feasible procedure and improves the functional outcomes of patients after low anterior resection.
