BACKGROUND : Radius Surgical System(Radius)is a two-hand-guided manipulator and has a de?ectable and rotatable tip of additional freedom of two-degrees comparing to conventional laparoscopic instruments. There have been few reports regarding clinical experiences of Radius for laparoscopic surgery including Laparoendoscpic Single-site(LESS)surgery. PATIENTS AND METHODS : From August 2008 to February 2010, 140 conventional laparoscopic surgical procedures were performed using Radius in our hospital; 30 cholecystectomies, 10 choledochotomies, 69 reconstruction for gastric cancer, and the other 25 procedures. Six LESS surgeries were also done using Radius: one cholecystectomy, two choledochotomy, one gastro-jejunal anastomosis for gastric bypass, and the other two local resections of the stomach. RESULTS : Radius enabled us to achieve the optimal penetration angle and was useful for both intracorporeal suturing and ligation such as the closure of the opening of the common bile duct and esophago-jejunostomy. Radius also was of value to overcome in-line viewing and hand/instruments collisions, which are common problems in LESS surgery. It also enabled us to perform complex procedures including Gambee's suture even in LESS surgery.

CONCLUSIONS : This is the largest clinical series of Radius presented to date. Radius facilitated advanced laparoscopic surgery and may have advantages in LESS surgery.
