    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.
