Background And Purpose:
Body mass index (BMI) has been shown to influence perioperative outcomes for patients undergoing open radical cystectomy and urinary diversion. The impact of BMI on robot-assisted intracorporeal ileal conduit has not been studied.
Patients And Methods:
All patients undergoing robot-assisted radical cystectomy (RARC) with ileal conduit at our institution were offered intracorporeal ileal conduit beginning May 2009. Fifty-six consecutive patients underwent robot-assisted radical cystectomy with intracorporeal ileal conduit from May of 2009 to July 2010. Patients were categorized into three groups based on BMI: Normal (BMI < 25 kg/m(2)), overweight (BMI=25-29 kg/m(2)), and obese (BMI ≥ 30 kg/m(2)). The effect of BMI on intraoperative and postoperative outcomes was assessed by retrospective review of a comprehensive RARC quality assurance database.
Results:
Median age at cystectomy was 72 (range 42-87 y), and 75% of patients were male. Median follow-up for the entire cohort was 5 months (range 12 d-16 mos). Median BMI was 27 kg/m(2) (range 19-47 kg/m(2)), and 75% of patients were overweight or obese. Age, ASA score, and overall operative time were not significantly different among the normal, overweight, and obese patients. Median urinary diversion times were 95, 151, and 124 minutes for normal, overweight, and obese patients, respectively (P=0.13).
Conclusions:
Robot-assisted intracorporeal ileal conduit can be safely performed in all body mass indices. Further studies are needed to assess long-term conduit function and stomal complications.
