Robotic Intracorporeal Padua Ileal Bladder: Surgical Technique, Perioperative, Oncologic and Functional Outcomes

BACKGROUND: Robot-assisted radical cystectomy (RARC) with intracorporeal neobladder reconstruction is a challenging procedure. The need for surgical skills and the long operative times have led to concern about its reproducibility. OBJECTIVE: To illustrate our technique for RARC and totally intracorporeal orthotopic Padua ileal bladder. DESIGN, SETTING, AND PARTICIPANTS: From August 2012 to February 2014, 45 patients underwent this technique at a single tertiary referral centre. SURGICAL PROCEDURE: RARC, extended pelvic lymph node dissection, and intracorporeal partly stapled neobladder. Surgical steps are demonstrated in the accompanying video. MEASUREMENTS: Demographics, clinical, and pathological data were collected. Perioperative, 2-yr oncologic and 2-yr functional outcomes were reported. RESULTS AND LIMITATIONS: Intraoperative transfusion or conversion to open surgery was not necessary in any case and intracorporeal neobladder was successfully performed in all 45 patients. Median operative time was 305min (interquartile range [IQR]: 282-345). Median estimated blood loss was 210ml (IQR: 50-250). Median hospital stay was 9 d (IQR: 7-12). The overall incidence of perioperative, 30-d and 180-d complications were 44.4%, 57.8%, and 77.8%, respectively, while severe complications occurred in17.8%, 17.8%, and 35.5%, respectively. Two-yr daytime and night-time continence rates were 73.3% and 55.5%, respectively. Two-yr disease free survival, cancer specific survival, and overall survival rates were 72.5%, 82.3%, and 82.4%, respectively. The small sample size and high caseload of the centre might affect the reproducibility of these results. CONCLUSIONS: Our experience supports the feasibility of totally intracorporeal neobladder following RARC. Operative times and perioperative complication rates are likely to be reduced with increasing experience. PATIENT SUMMARY: We report the outcomes of our first 45 consecutive patients who underwent robot-assisted radical cystectomy with intracorporeal neobladders. Perioperative, oncologic, and functional outcomes support this technique as a feasible and safe surgical option in tertiary referral centres.
