Abstract

Introduction: The Deloyers procedure was first described in 1963. It aims to rotate the right colon 180 degrees while maintaining the ileocolic blood flow, allowing for tension-free anastomosis following substantial left colon resections. This technique prevents permanent ostomy and maintains colonic absorptive function. This systematic review aimed to evaluate the surgical and functional outcomes of the Deloyers procedure. Methods: A systematic review was conducted following PRISMA-P guidelines and registered with PROSPERO (CRD420251039108). PubMed, Embase, and Web of Science were searched from inception through April 2025 for studies reporting outcomes of the Deloyers procedure. Eligible studies included original human research with extractable clinical data. Three reviewers independently screened the exported studies, extracted data, and assessed the quality of the included studies using Joanna Briggs Institute tools. Results: The inclusion criteria were met by 18 studies (n = 283 patients). The majority (50%) were case series with origins in Europe (44%) and Asia (33%). The most frequent indications were diverticular disease (13%), colorectal cancer (39%), and Hartmann reversal (9%). Laparoscopic and robotic procedures were less common than open surgery, which accounted for 82% of all procedures. In 55% of instances, a diverting ileostomy was employed. Ischemia and transfusions were among the reported intraoperative problems; anastomotic leak (3.5%) and ileus (4.6%) were among the late complications that occurred in 34% of patients. Bowel frequency was the main functional outcome, and follow-up ranged from 0 to 120 months. Conclusion: With good functional results and manageable complication rates, the Deloyers procedure is an effective choice for reestablishing bowel continuity following significant left-sided colon resections. This first systematic review of 283 patients highlights its role as an alternative to permanent ostomy or other reconstructive techniques. Larger, standardized studies are needed to define its clinical value better.
