Low or Ultralow Anterior Resection of Rectal Cancer Without Diverting Stoma: Experience with 28 Patients

Abstract

A diverting temporary stoma is frequently used to decrease the chance of anastomosis leakage in the middle and lower rectum cancer surgeries, but its role in preventing the leakage is still doubtful. This study has been designed to evaluate any possible anastomosis complications after a rectum resection and a low or ultralow anastomosis when no diverting stoma is applied in patients with rectal cancer. Twenty-eight patients suffering from rectal cancer were treated by a low anterior resection between the years 2005 and 2008 in Imam Reza University Hospital, Mashhad, Iran. Out of the 28 patients, 6 patients had already undergone a course of neoadjuvant radiotherapy. Anastomosis was performed manually in 23 patients, using a stapler in 5 of them. None of the patients had a diverting stoma. Then, the outcome was evaluated. Fecal incontinence occurred in one of the patients (6.7 %) who had already undergone a course of radiotherapy preoperatively and had a stapler used for anastomosis. No leakage was detected in any of them. The very low incidence of complications in this study, such as those not preventable by a diverting stoma, suggest a very low chance of leakage in low or ultralow anastomosis in patients with rectal cancer and in those who were treated with neoadjuvant radiotherapy.
