Antiperistaltic Side-to-Side Ileorectal Anastomosis Is Associated with a Better Short-Term Fecal Continence and Quality of Life in Slow Transit Constipation Patients

Abstract

Background: Surgical treatment of refractory slow transit constipation (STC) is traditionally performed using end-to-side ileorectal anastomosis (SE-IRA) with total abdominal colectomy (TAC). Antiperistaltic side-to-side (SS) IRA is suggested to be a superior approach. Employing a well-characterized cohort of STC patients, we compared the postoperative outcomes of the 2 surgical approaches. Methods: A total of 42 patients underwent TAC for refractory idiopathic STC. Twenty patients were treated using traditional SE-IRA whereas 22 patients were treated using SS-IRA. Patients were evaluated at 3 and 6 months as well as at 1 and 2 years after surgery. Both groups were compared for patient characteristics, perioperative data and quality of life. Cleveland Clinic Incontinence Score (CCIS) and Gastrointestinal Quality of Life Index (GQILI) were adopted for evaluating postoperative recovery. Results: Both study groups were comparable with respect to general patient characteristics, disease severity and post-operative complications. Fewer than 30% of all patients reported substantial dissatisfaction with surgical outcomes in both the groups. The SS-IRA group was associated with a lower postoperative CCIS (p < 0.05) and a better GQILI (p < 0.05) than that of the SE-IRA group during early follow-up examinations. Conclusion: In this study, SS-IRA was superior to traditional SE-IRA for the treatment of STC with respect to post-operative outcomes, and especially during early follow-up.
