Article Title: Open Versus Robotic Radical Prostatectomy in Obese Men
Abstract: OBJECTIVES: Robotic-assisted radical prostatectomy (RARP) has been shown to reduce blood loss, peri-operative complications and length of stay when compared to open radical prostatectomy (ORP). We sought to determine whether the reported benefits of RARP over ORP translate to obese patients. PATIENTS AND METHODS: We utilized the 2009-2010 Nationwide Inpatient Sample to identify all obese men with prostate cancer who underwent ORP and RARP. Our primary outcome was the presence of a peri-operative adverse event (i.e. blood transfusion, complication, prolonged length of stay). We fit multivariable logistic regression models to examine whether RARP in obese patients was independently associated with decreased odds of all three outcomes. RESULTS: We identified 9,108 obese patients who underwent radical prostatectomy. On multivariable analysis, the use of RARP in the obese population was not independently associated with decreased odds of developing a peri-operative complication (OR = 0.81, CI: 0.58-1.13, p = 0.209). RARP was, however, associated with decreased odds of blood transfusion (OR = 0.17, CI: 0.10-0.30, p 0.001) and prolonged length of stay (OR = 0.28, CI: 0.20-0.40, p 0.001). CONCLUSION: Our findings suggest that in obese patients, the use of RARP may reduce length of stay and blood transfusions compared to ORP. Both approaches, however, are associated with similar odds of developing a complication.
