Early Closure Versus Conventional Closure in Postoperative Patients With Low Anteriresection for Rectal Cancer

Colonic Neoplasms, Colorectal Surgery, Ileostomy - Stoma

Colorectal cancer worldwide is the third most common in men and the second in female, although mortality is not as high as its incidence, there is less survival in developing countries. According to data from the World Health Organization, in 2012, there were an estimated 1.4 million cases and 693,900 deaths from this disease. Patients with rectal cancer are frequently taken to resection surgery as a curative management of their malignant pathology, according to the type of resection or reconstruction. In a high number of cases, they are management with colorectal anastomosis with a derivative ileostomy in the same procedure. The closure of this ileostomy is usually done after two to three months of the procedure, however in our environment it could take up to six or twelve months, during which time the patient is exposed to social difficulties, management problems and complications, derived from it. The early closure (7-12 days of its creation) of an ileostomy, despite the little evidence, seems to be a safe, feasible procedure that would save the patient having to live temporarily with an ileostomy.

General purpose: To compare the frequency of perioperative complications and quality of life between early closure of the derivative ileostomy versus conventional closure in postoperative patients with low anterior resection for rectal cancer. Materials and methods: Controlled clinical trial, randomized, to be carried out at the National Cancer Institute of Colombia E.S.E. Eligible candidates for the study will be patients older than 18 years who have undergone a previous resection of the rectum plus a derivative ileostomy for colorectal cancer. All patients eligible for inclusion will undergo computed axial tomography with rectal contrast medium on postoperative day 5. Those who meet the inclusion criteria and do not present any of the exclusion criteria will enter the study, prior willingness to participate by part of the patient and obtaining verbal and written informed consent. Through computer-generated randomization, patients will undergo early closure (between 7 and 12 days after the ileostomy) versus conventional closure (after 90 days or more time from the creation of the ileostomy). A sample size of 81 patients was calculated for each arm. The follow-up will be done in both groups at 3, 6, 9 and 12 months after the creation of the ileostomy, including complications using the Clavien-Dindo classification and quality of life using the FACIT-C format. The statistical analysis will be done by protocol and intention to treat. The perioperative complications associated with the closure of the ileostomy, the complications associated with the presence of ileostomy, hospital stay, and quality of life will be analyzed. Expected impact: The investigators hope to find that the early closure of ileostomy in patients during the immediate postoperative period of previous resection due to rectal cancer is safe in terms of morbidity and mortality, feasible and with benefits in quality of life during the immediate postoperative period compared with patients to whom they are closed late (after 3 months).
