title: Robotic single port cholecystectomy (R-LESS-C): experience in 36 patients.
abstract: BACKGROUND
  Laparoendoscopic single-site surgery (LESS) has emerged as a result of a search for "pain-less" and "scar-less" surgery. Laparoendoscopic single-site cholecystectomy (LESS-C) is probably the most common application in general surgery, although it harbors certain limitations. It was proposed that the da Vinci Single-Site (Si) robotic system may overcome some of the difficulties experienced during LESS, providing three dimensional views and the ability to work in a right-handed fashion. Thirty-six robotic single port cholecystectomies (R-LESS-C) performed with the da Vinci Si robotic system are evaluated in this paper
  
  
  METHODS
  R-LESS-C performed in 36 patients were reviewed. The data related to the perioperative period (i.e., anesthesia time, operation time, docking time, and console time) was recorded prospectively, whereas the hospitalization period, postoperative visual analogue scale (VAS) pain scores were collected retrospectively.
  
  
  RESULTS
  A total number of 36 patients, with a mean age of 40.1 years (21-64 years), underwent R-LESS-C. There were five men and 31 women. The mean anesthesia and operation times were 79.3 minutes (45-130 minutes) and 61.8 minutes (34-110 minutes), respectively. The mean docking time was 9.8 minutes (4-30 minutes) and the mean console time was 24.9 minutes (7-60 minutes). The mean hospital stay was 1.05 days (1-2 days) and the mean pain score (VAS) was 3.6 (2-8) in the first 24 hours. Incisional hernia was recorded in one patient.
  
  
  CONCLUSIONS
  R-LESS-C can be performed reliably with acceptable operative times and safety. The da Vinci Si robotic system may ease LESS-C. Two issues should be considered for routine use: expensive resources are needed and the incidence of incisional hernia may increase.
