Robot-assisted intracorporeal ileal conduit: Marionette technique and initial experience at Roswell Park Cancer Institute.
OBJECTIVE
To present our technique and initial experience with patients who underwent robot-assisted intracorporeal creation of ileal conduit and to compare them with patients who underwent extracorporeal ileal diversion after robot-assisted radical cystectomy.


METHODS
Twenty-six patients diagnosed with invasive transitional cell carcinoma of the bladder underwent a robot-assisted radical cystectomy with bilateral extended pelvic lymphadenectomy with ileal conduit diversion. Total intracorporeal ileal conduit creation was performed in the last 13 patients. Operative data and short-term outcomes between the 2 groups were assessed. The novel surgical technique for intracorporeal ileal conduit will be presented.


RESULTS
The intracorporeal group (IC) included 2 female and 11 male patients (mean age 71 years). The extracorporeal group (EC) included 4 female and 9 male patients (mean age 66 years). No significant differences were noted between the groups in terms of patient age, BMI, sex, prior surgery, or pathologic stage. Overall operative time and intraoperative complications were similar. No significant differences were noted between the 2 groups in terms of diversion time or estimated blood loss. There were 4 complications recorded in IC patients, including nonspecific colitis, small bowel obstruction requiring exploratory laparotomy with lysis of adhesions, a urine leak that eventually resolved but required a temporary nephrostomy tube, and a fever of unknown origin that resolved without intervention.


CONCLUSIONS
Robot-assisted intracorporeal ileal conduit can be accomplished safely with acceptable operative times even during early experience. Larger series with favorable results will be required to add this new paradigm to minimally invasive surgery for bladder cancer.
