Abstract

AIM: 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.

CONCLUSION: Robotic cholecystectomy using new port sites on the low abdominal area can be safely and efficiently performed, with sufficient patient satisfaction.

Keywords: Robotic cholecystectomy, Port sites, Operation time, Abdominal area, Gallbladder disease

Core tip: The robotic procedure is safe; however, it is not acceptable as a standard operation for gallbladder disease because of its lack of benefits for patients as a result of the high cost and prolonged operating time. In the previous studies, port sites of robotic cholecystectomy were located on the supraumbilical area, similar to laparoscopic surgery. In this study, we changed the port placements from the upper abdominal area to the lower abdominal area.
