Single‐Site Robotic Cholecystectomy: The Timeline of Progress

Abstract

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.
