Abstract
BackgroundThe need for the left ureter to pass through the subsigmoid during ileal conduit diversion surgery has not been investigated in any studies. A modified technique is simply used in the ileal conduit with the left ureter straight over the sigmoid colon due to the possible damage and lack of scientifically validated advantages of this procedure. Our study aimed to investigate the feasibility of the suggested surgical technique, as well as to evaluate perioperative outcomes and postoperative complications with a focus on the prevalence of small bowel obstruction (SBO) and ureteroileal anastomotic stricture (UAS).MethodsA prospective single-center cohort of 84 consecutive patients undergoing laparoscopic radical cystectomy (LRC) and ileal conduit urinary diversion was conducted between January 2018 and April 2020. The incidence of SBO and UAS, perioperative outcomes, and postoperative complications were compared between a trial group of 30 patients receiving the modified procedure and a control group of 54 patients receiving the conventional Bricker ileal conduit.ResultsThe two groups were comparable concerning patient characteristics and clinicopathologic features. No differences were observed in terms of the operation time, perioperative outcomes, and short-term (< 90 days) postoperative complications between the two groups. There were no occurrences of UAS in the modified group, while there were two cases (3.70%) in the patients who received Bricker's ureteroileal anastomosis (p = 0.535).ConclusionIn the present study, a simple and feasible modified technique of ileal conduit is proposed. Compared with traditional techniques, our method has several advantages, including the ability to avoid compression of the left ureter from the mesentery without establishing a retrosigmoid tunnel, a low rate of UAS, and the ability to perform a secondary operation at long-term follow-up.
