Abstract
Aim
The aim of this study is to evaluate the clinical outcomes and cost-effectiveness of elective, robot-assisted choledochotomy and common bile duct exploration (RCD/CBDE) compared to open surgery for ERCP refractory choledocholithiasis.
Method
A prospective database of all RCD/CBDE has been maintained since our first procedure in April 2007 though April 2016. With ethics approval, this database was compared with all contemporaneous elective open procedures (OCD/CBDE) performed since March 2005. Emergency procedures were excluded from analysis. Cost analysis was calculated using a micro-costing approach. Outcomes were analyzed on the basis of intent-to-treat. A p value of 0.05 denoted statistical significance.
Results
A total of 80 cases were performed since 2005 compromising 50 consecutive, unselected RCD/CBDE and 30 OCD/CBDE. Comparing RCD/CBDE to OCD/CBDE there were no significant differences between groups with respect to age (65 ± 20 vs. 67 ± 18 years, p = 0.09), gender (14/30 vs. 16/25 male/female, p = 0.52), ASA class or co-morbidities. The mean duration of surgery for RCD/CBDE trended longer compared to OCD/CBDE (205 ± 70 min vs. 174 ± 73 min, p = 0.08). However, there was significant reduction in postoperative complications with RCD/CBDE versus OCD/CBDE (22% vs. 56%, p = 0.002). Median hospital stay was also significantly reduced (6 vs 12 days, p = 0.01). The net overall hospital cost for RCD/CBDE was lower ($8449.88 CAD vs. $11671.2 CAD).
Conclusion
In this single-centre, cohort study, robotic-assisted CD/CBDE for ERCP refractory common bile duct stones provides the dominating strategy of improved patient outcomes with a reduction of overall cost.
