Abstract
Purpose
To analyze the feasibility and perioperative results of patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis.
Methods
This is a mono-centric analysis of perioperative data from 48 consecutive patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. Data include the preoperative variables, operative and postoperative course and complication rates related to bowel anastomosis. End points were time spent for anastomosis and intra- and postoperative complication rates.
Results
Median operating time was 23.0 (13–60) min for the ileoileal anastomosis. Median overall operating time was 295 (200–780) min, with a median of 282 (200–418) min and 414.0 (225–780) min for the ileum conduit (N = 35) and ileal neobladder (N = 13). Two patients developed paralytic ileus; in another patient acute peritonitis occurred, but was caused by urinary leakage and therefore unrelated to the bowel anastomosis. No anastomotic leakage was noticed. Costs for the robot-sewn anastomosis was 8€ compared to 1250€ for a stapled anastomosis which was performed in previous cases. Limitations are the non-comparative nature of the analysis and the limited number of patients.
Conclusions
Robot-sewn ileoileal anastomosis is feasible with low complication rates. Compared to the stapled anastomosis, a robot-sewn ileoileal anastomosis may serve as an alternative and cost-saving approach.
