A novel antireflux technique using an intussuscepted ileal segment.
A novel surgical technique of antireflux with an ileal conduit for urinary diversion is presented with our early results. The mid 8-cm portion of an isolated terminal ileum is intussuscepted. After skeletonization of the mesenterial vasculature, 3 rows of 4 mattress seromuscular silk sutures are placed on the ileum. By tying the sutures successively, the ileum is intussuscepted and the resultant nipple is secured simultaneously between its outer and inner layers. The outer nipple layer and the recipient ileal layer are further fixed as a whole by placing 3 rows of metal staples. The nipple base is secured by interrupted silk sutures and the mesenterial defect is closed. This technique was applied to 30 patients undergoing rectosigmoidal bladder procedure, a modified ileocecal rectal bladder, in which the antireflux conduit was interposed between the ureters and the rectosigmoidal pouch. Ureteral reflux was observed in none of the patients during a mean follow-up period of 29.9 months. Of the 60 renal units, 53 (88.3%) had normal pyelography and 7 (12.7%) showed mild hydronephrosis at 3-6 months postoperatively. This antireflux technique is simple and reliable, and can be applied to other urinary diversion/reconstruction surgeries, such as the continent reservoir, orthotopic neobladder, and/or bladder augmentation.
