Totally intracorporeal 3D laparoscopic orthotopic neobladder reconstruction following radical cystectomy for infiltrative bladder tumors: the experience of modified Studer and modified Y-shaped ileal reconstruction techniques.

Purpose: We report our experience with 23 cases in utilizing ileum to perform totally intracorporeal 3D laparoscopic neobladder reconstruction using two different surgical techniques.
Methods: Patients candidates for reconstructive surgery were in a good biological status with a body mass index (BMI) in the range of 18.5-25 and presented a muscle-infiltrative bladder tumor with negative nodal frozen sections performed during the operation. Twenty-one modified Studer neobladder and 2 modified Y-shaped neobladder techniques for totally intracorporeal 3D laparoscopic ileal neobladder cases were performed using drawings and intra-operative images. An emphasis was made on different tips and tricks that can be applied when using ileum for the neobladder reconstruction, to avoid surgical complications and obtain optimal functional results.
Results: The operations were performed in a mean time of 5 h, with a mean blood loss of 350 ml and grade II postoperative Clavien Dindo complications. The 23 patients were discharged after a mean hospital stay of 21 days and had a functional ileal neobladder after a mean of 30 days. The results were monitored also on the long-term, taking into account functional results and possible complications from utilizing ileum as a urinary reservoir.
Conclusion: Resecting a digestive segment and using it as a urinary reservoir may lead to multiple complications. Therefore, laparoscopic technical adaptations and highly skilled surgical teams are required for performing a totally intracorporeal 3D laparoscopic orthotopic ileal neobladder reconstruction.
