Study Shows Robotic-Assisted Prostate Surgery Reduces Hospital Readmission and Complication Rates Compared to Open Surgery
This retrospective study used the National Surgical Quality Improvement (NSQIP) database to analyze data on patients who received a prostatectomy in 2011. A total of 5,471 patients and more than 400 hospitals were included in the study. Of those patients, 1,097 (20 percent) had an open procedure and 4,374 (80 percent) had a minimally invasive robotic-assisted procedure. No patients had a laparoscopic procedure.
Overall, the robotic-assisted group experienced significantly lower overall complication rates, surgical complication rates, and unplanned readmission rates. Although the operative time was significantly longer for the robotic-assisted group than for the open group, this did not result in higher complications during or after surgery. A full comparison between the two procedures showed:1
|Robotic-assisted Prostatectomy (n=4374)||Open Prostatectomy (n=1097)|
|Overall Complication Rate (p<0.001)*||5.62%||23.25%|
|Surgical Complication Rate (p<0.001)*||0.91%||3.37%|
|Unplanned Readmission Rate (p=0.002)*||3.48%||5.47%|
|Operative Time (p=0.001)*||212.3 minutes||174.0 minutes|
|*p<0.05 denotes a statistically significant value.|
Because this was a retrospective study, the researchers could not factor in certain variables, such as patient selection bias and co-morbidities (other illnesses that could affect the outcomes of the patient's surgery). The only lifestyle variables included in the analysis were smoking and alcohol use.
Important Information for Patients
Potential risks of any prostatectomy procedure include urinary and/or sexual dysfunction due to nerve damage2, rectal or bowel injury3, blocked artery in the lung3, or blocked bowel.3
All surgery presents risk, including da

About the da Vinci Surgical System
The da Vinci Surgical System is a surgical platform designed to enable complex surgery using a minimally invasive approach. The da Vinci Surgical System consists of an ergonomic surgeon console or consoles, a patient-side cart with three or four interactive arms, a high-performance vision system and proprietary EndoWrist® instruments. Powered by state-of-the-art technology, the da Vinci Surgical System is designed to scale, filter and seamlessly translate the surgeon's hand movements into more precise movements of the EndoWrist instruments. The net result is an intuitive interface with improved surgical capabilities. By providing surgeons with superior visualization, enhanced dexterity, greater precision and ergonomic comfort, the da Vinci Surgical System makes it possible for skilled surgeons to perform more minimally invasive procedures involving complex dissection or reconstruction.
