Cecorectal (CRA) versus ileorectal (IRA) anastomosis after colectomy for slow transit constipation (STC): a meta-analysis

Abstract

Introduction: We conducted this meta-analysis, to compare cecorectal (CRA) and ileorectal anastomosis (IRA), regarding perioperative safety and efficacy, in patients submitted to colectomy for refractory slow transit constipation (STC). Methods: This study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. To identify all eligible records, a systematic literature search in the electronic scholar databases (Medline, Scopus, Web of Science) was performed. Results: Overall, 5 trials and 291 patients were included in this meta-analysis. Pooled comparisons confirmed the comparability of the two techniques regarding perioperative complications (p = 0.55). CRA was associated with a shorter operation (p = 0.0004) and hospitalization duration (p = 0.001). Although there was no difference in terms of gastrointestinal symptoms, functional outcomes, and patient satisfaction, CRA resulted in lower long-term Wexner scores (p < 0.0001). Conclusion: Due to several study limitations, further large-scale RCTs are required to verify the findings of the present meta-analysis. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
