Abstract
Introduction: The ileal reservoir with anal-reservoir anastomosis (IRARA) is a procedure of intestinal transit reconstruction that is performed after a proctectomy and tries to simulate the functionality of the rectal ampulla to reduce episodes of incontinence. The aim of the present study was to describe the perioperative complications of the procedure and the functional results at 1 year.
Methods: The present observational study is a review of IRARA patient records, between July 2014 and September 2016, in the Surgery service of the “Clínica-Guayaquil”. The sample was non-probabilistic for convenience. All patients underwent a coloproctectomy. Early complications were measured using the Clavien-Dindo scale. Functional results one year after surgery were assessed with the Öresland test. Descriptive statistics is used.
Results: 45 cases were included (35 men and 10 women), average age was 55 years, who underwent coloproctectomy, 8 cases for Familial Adenomatose Polyposis, 3 for Ulcerative Colitis and 34 for colorectal cancer. Complications occurred in 18 patients (40%), 12 cases (26.7%) with Hydro-electrolyte disorders, 3 pelvic collections 1 requiring reoperation and 1 with prolonged drainage. Complications of Level II 83.33%. The average of evacuations was 5 in 24 hours in the first three months. Öresland score from 0 to 3 points, in 34 patients (80%) per year.
Conclusions: The results of this series show good functional results at one year of the IRARA procedure, morbidity of level III acceptable and without mortality in this report. Long-term follow-up is necessary to identify late complications.
