Aim:
Given the growing adoption of robot-assisted hepatobiliary-pancreatic (HBP) surgery and the limited availability of robotic systems, high-volume centers must optimize operating room time management. However, data on multiple robot-assisted HBP surgeries performed on a single workday are limited. This study investigated the outcomes of sequential robot-assisted HBP performed in a single operating room.
Methods:
This single-center retrospective study included 122 robot-assisted HBP surgeries performed sequentially in a single operating room between September 2020 and September 2025. The outcomes and operating room timelines of the sequential procedures were analyzed, including the incidence of "day-shift completion (defined as patient wheel-out by 5:30 PM)".
Results:
The procedures performed included robot-assisted distal pancreatectomy (n = 33), liver resection (n = 85), and congenital biliary dilatation (n = 4). The overall operative time was 171 min (interquartile range [IQR], 129-203 min), and the median blood loss was 8 mL (IQR, 0-100 mL). The outcomes and operating room timelines were comparable between the first and second cases. The median turnover time was 49 min (IQR, 43-56 min). The success rate of day shift completion was 34.4%.
Conclusions:
This study demonstrated the safety and feasibility of sequential robot-assisted HBP surgery in a single operating room. Appropriate case selection may help successfully implement sequential robot-assisted HBP surgeries.
