Colonic transit before and after resection rectopexy for full-thickness rectal prolapse

Background: The objective of this study was to measure the change in colonic transit time after resection rectopexy for complete rectal prolapse. Methods: We prospectively carried out isotope colonic transit studies before resection rectopexy in 38 patients with full-thickness complete rectal prolapse and invited them to attend for a postoperative transit study at least 1 year after resection rectopexy. Results: Preoperatively, 27 (70 %) patients had abnormally prolonged colonic transit times, while 11 had normal colonic transit. Twenty-two (61 %) patients agreed to attend for a three-day colonic transit study. Resection rectopexy failed to correct delayed colonic transit in all patients with abnormal preoperative tests, while 4 patients developed new delayed transit and 2 with normal transit were unchanged. Conclusions: The study suggests that most prolapse patients have a pan-colonic motility disorder that is not corrected by rectopexy and resection of most of the left colon. If resection rectopexy fails to correct abnormal transit, this study questions the rationale for continuing to offer resection and supports less invasive surgical procedures such as ventral rectopexy. © 2013 Springer-Verlag Italia.
