PURPOSE: To describe the technique of laparoscopy-assisted undiversion of an ileal conduit into a continent orthotopic ileal neobladder performed on a patient with a previous radical cystoprostatectomy and ileal conduit.
CASE REPORT: A 57-year-old man presented with a prolapsed stoma and a history of a right radical nephroureterectomy for grade 3 ureteral transitional-cell carcinoma and a radical cystoprostatectomy and ileal conduit urinary diversion for in-situ bladder carcinoma, performed 12 and 8 years ago, respectively. After the ileal stoma was resected, five trocars were placed transperitoneally. Partial resection of the distal ileal conduit was performed, leaving in place the proximal segment with its left ureteroileal anastomosis. Flexible urethroscopy revealed a contracting external sphincter, and random urethral frozen-section biopsies ruled out tumor. A 45-cm segment of ileum was isolated and exteriorized through the stoma site, and an ileal neobladder was created extracorporeally, suturing the proximal ileal-conduit segment, with its ureteroileal anastomosis, to it. The ileal neobladder was reintroduced into the abdomen and anastomosed laparoscopically to the urethral stump with six 2-0 polyglactin sutures. The total operative time was 7 hours with a blood loss of 100 mL. There were no intraoperative complications. The hospital stay was 7 days. At a follow-up of 24 months, the patient had total daytime continence and normal renal function, and intravenous urography revealed an unobstructed urinary tract.
CONCLUSION: Laparoscopy-assisted ileal-conduit undiversion into an orthotopic ileal neobladder is technically feasible. It can be considered an alternative to open surgery for patients who have undergone urinary diversion.
