title: Robotic cholecystectomy with new port sites.
abstract: OBJECTIVE
  To introduce robotic cholecystectomy (RC) using new port sites on the low abdominal area.
  
  
  METHODS
  From June 2010 to June 2011, a total of 178 RCs were performed at Ajou University Medical Center. We prospectively collected the set-up time (working time and docking time) and console time in all robotic procedures.
  
  
  RESULTS
  Eighty-three patients were male and 95 female; the age ranged from 18 to 72 years of age (mean 54.6 ± 15.0 years). All robotic procedures were successfully completed. The mean operation time was 52.4 ± 17.1 min. The set-up time and console time were 11.9 ± 5.4 min (5-43 min) and 15.1 ± 8.0 min (4-50 min), respectively. The conversion rate to laparoscopic or open procedures was zero. The complication rate was 0.6% (n = 1, bleeding). There was no bile duct injury or mortality. The mean hospital stay was 1.4 ± 1.1 d. There was a significant correlation between the console time and white blood cell count (r = 0.033, P = 0.015). In addition, the higher the white blood cell count (more than 10000), the longer the console time.
  
  
  CONCLUSIONS
  Robotic cholecystectomy using new port sites on the low abdominal area can be safely and efficiently performed, with sufficient patient satisfaction.
