Abstract
Background and Purpose: The Pfannenstiel incision provides good access to the bladder and bladder neck for major reconstructive surgery in the thin patient, whereas a midline incision is often necessary to get adequate exposure in the obese patient. We describe our experience using laparoscopic-assisted continent urinary diversion in conjunction with other bladder and bladder neck surgery in obese patients. Patients and Methods: Three female patients (mean age 18; mean weight 175 pounds) with neurogenic bladder underwent Mitrofanoff appendicovesicostomy continent urinary diversion to the umbilicus and pubovaginal sling. An umbilical port for the telescope and two lateral ports were used. Once the appendix and right hemicolon had been completely mobilized up to the hepatic flexure, reconstruction was completed through a low Pfannenstiel incision. Results: There were no laparoscopic complications. None of the laparoscopic port sites was visible postoperatively, as one was in the base of the umbilicus, and the other two had been incorporated into the Pfannenstiel incision. With a mean follow-up of 1 year, all patients were continent and catheterizing their umbilicus easily. Pfannenstiel incisions were well healed, and the patients were quite satisfied with their cosmesis. Conclusion: Laparoscopic-assisted Mitrofanoff appendicovesicostomy continent urinary diversion to the umbilicus can be performed in conjunction with a Pfannenstiel incision to complete major bladder and bladder neck surgery in the obese patient with good postoperative cosmesis. This procedure represents a nice compromise between a very lengthy bladder reconstructive procedure done purely laparoscopically and a midline incision with good exposure but suboptimal cosmesis.
