ABSTRACT
BACKGROUND: The aim of this study was to compare the outcomes of single-site robotic cholecystectomy with multi-port laparoscopic cholecystectomy within a high-volume tertiary health care center. METHODS: A retrospective analysis of prospectively maintained data was conducted on patients undergoing single-site robotic cholecystectomy or multi-port laparoscopic cholecystectomy between October 2011 and July 2014. A single surgeon performed all the surgeries included in the study. RESULTS: A total of 678 cholecystectomies were performed. Of these, 415 (61%) were single-site robotic cholecystectomies and 263 (39%) were multi-port laparoscopic cholecystectomies. Laparoscopic patients had a greater mean BMI (30.5 vs. 29.0 kg/m2; p = 0.008), were more likely to have undergone prior abdominal surgery (83.3 vs. 41.4%; p < 0.001) and had a higher incidence of preexisting comorbidities (76.1 vs. 67.2%; p = 0.014) as compared to the robotic group. There was no statistical difference in the total operative time, rate of conversion to open procedure and mean length of follow-up between the two groups. The mean length of hospital stay was shorter for patients within the robotic group (1.9 vs. 2.4 days; p = 0.012). Single-site robotic cholecystectomy was associated with a higher rate of wound infection (3.9 vs. 1.1%; p = 0.037) and incisional hernia (6.5 vs. 1.9%; p = 0.006). CONCLUSION: Multi-port laparoscopic cholecystectomy should remain the gold standard therapy for gallbladder disease. Single-site robotic cholecystectomy is an effective alternative procedure for uncomplicated benign gallbladder disease in properly selected patients. This must be carefully balanced against a high rate of surgical site infection and incisional hernia, and patients should be informed of these risks.

AIM: To investigate the learning curve and perioperative outcomes of single-site robotic cholecystectomy during the first 102 cases by a single surgeon. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database was performed on the first 102 cases of single-site robotic cholecystectomy. Patients were divided into five chronological groups based on the date of surgery, with 20 patients in each group except the 5th group which had 22 patients. The groups were compared by docking time, robotic dissection time, and overall surgery time. A P value of 0.05 was used as statistically significant. RESULTS: The female to male ratio was 2:1. The mean age was 51 years (18-87) and the mean BMI was 28.26 (18-41). Overall, 69 % of the patients underwent elective cholecystectomy and 31 % required urgent surgery. In all, 17 % of patients had previous abdominal surgeries. In total, 45 % of procedures were regarded as same day surgery. The total mean length of stay was 1.97 days (0-8). The mean operative time was 110 min (36-265), mean robotic console time 70 min (26-179), and mean docking time 9 min (1-26). The overall conversion rate was 3.9 % and the complication rate was 4 %. The docking time, robotic time, and average operative time were significantly different in the first group as compared to the remaining the five groups (P = 0.001). CONCLUSION: Single-site robotic cholecystectomy is safe in both elective and urgent conditions, and in patients with previous abdominal surgeries. It has a short learning curve.
