Abstract
Abstract Background A recent large retrospective cohort study reported a higher risk of bile duct injury associated with robotic cholecystectomy when compared to the laparoscopic approach. Considering that most robotic training pathways, including the one followed in the UK, utilise robotic cholecystectomy as index training procedure, such findings mandate evaluation of the safety profile of robotic cholecystectomy in the UK to ensure its use as an alternative approach to laparoscopic cholecystectomy is not putting patients at risk. We aimed to conduct a multi-centre observational study to evaluate the safety profile of robotic cholecystectomy performed within the UK HPB Robotic training program. Method A retrospective analysis of prospectively collected data from eleven centres participating in the UK robotic HPB training program was conducted. All adult patients undergoing robotic cholecystectomy for symptomatic gallstone disease or gallbladder polyp were considered. Bile duct injury, conversion to open procedure, conversion to subtotal cholecystectomy, length of hospital stay, 30-day re-admission, and post-operative complications were the evaluated outcome parameters. Results A total of 600 patients were included. The median age was 53 (IQR 65 - 41) years and the majority (72.7%; 436/600) were female. The main indications for robotic cholecystectomy were biliary colic (55.5%, 333/600), cholecystitis (18.8%, 113/600), gallbladder polyps (7.7%, 46/600) and pancreatitis (6.2%, 37/600). The median length of stay was 0 (IQR: 0-1) days. Of the included patients, 88.5% (531/600) were discharged on the day of procedure with 30-day re-admission rate of 5.5% (33/600). There were no bile duct injuries and the rate of conversion to open was 0.8% (5/600) with subtotal cholecystectomy rate of 0.8% (5/600). Conclusion This current study confirms that robotic cholecystectomy can be safely implemented to routine practice with a low risk of bile duct injury, low conversion to open surgery and low need for subtotal cholecystectomy.
