Completely intracorporeal robotic-assisted laparoscopic augmentation enterocystoplasty with continent catheterizable channel

Objective To report our results from series of robotic-assisted laparoscopic augmentation enterocystoplasty (RALAE) performed in a completely intracorporeal fashion. Methods Patients who underwent RALAE with or without the creation of a catheterizable channel between 2006 and 2011 at the University of Texas, Houston and Northwestern Memorial Hospital were identified. Perioperative and follow-up data were analyzed. Preoperative and postoperative urodynamic data were analyzed when available. Results Twenty-two patients with neurogenic bladder underwent RALAE with or without the creation of a catheterizable channel. Fifteen patients underwent robotic augmentation enterocystoplasty alone, and 7 patients had creation of a catheterizable channel (4 Monti and 3 Mitrofanoff). There was 1 conversion to an open procedure in a patient undergoing concomitant creation of an appendicovesicostomy. Mean follow-up was 38.9 months (range, 6.2-72.1 months). Mean operative time was 365 minutes (range, 220-788 minutes); mean estimated blood loss was 110 mL (range, 30-250 mL). Median time to return of bowel function was 5 days (range, 2-17 days). Preoperative and postoperative urodynamic data were available for 13 patients. Mean cystometric capacity increased by 52%, and mean maximal bladder pressures decreased by 40. There were 5 minor complications (Clavien grade 1-2) and 4 major complications (Clavien grade 3-4). No patient experienced a wound infection. Conclusion RALAE is a feasible approach that provides potential benefits over open bladder reconstruction in the neurogenic voiding dysfunction population.
