robotic technology leads to a lower positive surgical margin rate, the researchers said. The Jefferson urologists reviewed the cases of 247 men with clinically localized prostate cancer treated at Thomas Jefferson University Hospital with either LRP or robotic assisted laparoscopic prostatectomy (RALP) from March 2000 to August 2006. Of the 247 cases, 197 patients underwent LRP and 50 patients underwent robotic assisted laparoscopic prostatectomy.

The overall positive surgical margin rate for patients who had LRP was 18 percent, as compared to six percent for those who had RALP.

The Jefferson researchers said they believed the results were so positive here because of the way they approach each case.

We individualize each case and consider the patient, as well as his particular anatomy and preoperative cancer-related characteristics to plan his procedure, said Dr. Lallas. In addition, the majority of our patients are evaluated in a multidisciplinary genitourinary cancer clinic, emphasizing our focus on the oncologic aspect of this operation.

Laparoscopic surgery has proven to offer potential advantages to patients including less trauma through smaller incisions, faster recovery and less overall blood loss during surgery, allowing most patients to leave the hospital in one to two days.

The robotic system further refines laparoscopic prostatectomy by allowing a surgeons hand movements to be scaled, filtered and translated into precise movements of micro-instruments within the operative field. The magnified, three-dimensional view the surgeon experiences enables him to perform precise surgery in complex procedures, such as radical prostatectomy, through small surgical incisions.
