title: Comparison of standard and hand-assisted laparoscopic radical nephrectomy for renal cell carcinoma.
abstract: A laparoscopic radical nephrectomy (LRN) for renal cancer can be performed using two methods, hand-assisted laparoscopic surgery (HALS) and standard laparoscopic surgery (SLS). This institute initially used HALS to perform all radical nephrectomy, but gradually shifted to SLS. This study compared the two methods of radical nephrectomy: HALS vs. SLS, which were performed at a single institute. From March 1999 to November 2006, a total 129 patients with pathologically confirmed renal cell carcinoma underwent LRN, including 73 patients with the HALS and 56 patients with SLS. The median operative time was 264 minutes, and median estimated blood loss was 200 ml in the HALS group, respectively. The median operative time and median estimated blood loss in the SLS were 215 minutes and 100 ml, respectively. There was no significant difference in either the operative time or estimated blood loss between HALS and SLS. The median time to both postoperative oral intake and ambulation in the SLS were 1 day. Neither of these events after SLS was significantly shorter than that after HALS. The 4-year disease-free and overall survival rates in the HALS patients were 97.5% and 98.2%, respectively. Both the 4-year disease-free and overall survival rates in the SLS patients were 100%. Since no significant differences were observed between the two operative methods (SLS and HALS) regarding the operative data, postoperative course and oncological outcome, the surgical method for LRN can be selected according to characteristics of each surgical method.
