To evaluate the impact of obesity on patients developing wound complications within 30 days of open and robotic radical prostatectomy using the National Surgical Quality Improvement Program (NSQIP).


Patients undergoing radical prostatectomy in 2011 to 2012 were identified from NSQIP, which is a multi-institutional database of comprehensive 30-day postoperative outcomes. Wound complication included superficial surgical site infections (SSIs), deep SSI, organ space infections, and dehiscence. Descriptive statistics and multiple logistic regression examined the relationship between obesity and wound complications in open and robotic radical prostatectomy.


Of the 12,454 radical prostatectomy cases reported in the study period, 9248 were robotic (74%), 2244 (18%) patients were normal weight (body mass index [BMI] <25), 5836 (47%) were overweight (BMI 25-30), and 4374 (35%) were obese (BMI >30). Wound complications occurred in 134 (4%) of open and 114 (1%) of robotic radical prostatectomies. After adjusting for age, history of smoking, history of diabetes, history of chronic steroid use, and operative time, it was determined that obese patients were at 71% increased odds of developing a wound complication after open prostatectomy (pā€‰=ā€‰0.034), while there was no difference in the odds of a wound complication after robotic radical prostatectomy (odds ratio 1.14, pā€‰=ā€‰0.665).


Obese patients are at increased risk of developing wound complications when undergoing open vs robotic radical prostatectomy. Obese patients likely benefit from robotic radical prostatectomy whenever feasible.
