Introduction : The robotic platform might offer superior ergonomics over other minimally invasive approaches. Instruments are wristed with a wide range of motion and the view is 3-dimensional and magnified. With instruments with a greater range of motion than in laparoscopic surgery, the use of a robotic system potentially broadens indications for minimally invasive surgery in HBP field. However, the increased time required for instrument set-up, operations, and surgical training are perceived as major drawbacks. We report our experience at Chonbuk national medical center in HBP field.

Methods : From September 2017 to November 2019, all consecutive patients(n=112) who underwent robotic surgery were retrospectively analyzed. Variables of interest for this study were patient demographics, operative times for the procedure and morbidities.

Results : Among 112 patients, 98 from cholecystectomy, 7 from hepatectomy, 6 from pancreatectomy and 1 from bile duct resection. The mean age of recipients was 45.2 years with range of 15-68 years.. The Hepatectomy was performed in 2 HCC cases and 5 benign disease cases, The pancreatectomy(distal 3, pancreaticoduodenectomy 3) and bile duct resection were performed in benign diseases. The mean docking and operating times were 8.7(83) mins in cholecystectomy, 14(289)mins in hepatectomy , 28(368)mins in distal pancreatectomy, and 25 (590)min in pancreticoduodenectomy Total numbers of open and laparoscopic conversion are 2 cases cause of sever adhesion. Postoperative complications were bile leak(1 case in bile duct resection) and cholangitis (1case in cholecystectomy)

Conclusions : In our results, robotic assisted laparoscopic surgery in HBP filed is feasible and safe for a variety of procedures.
