Surgical Outcomes of Sequential Robot‐Assisted Hepatobiliary–Pancreatic Surgery in a Single Operating Room: A Single‐Center Retrospective Analysis of a High‐Volume Center in Japan ( <scp>TAKUMI</scp> ‐6)

ABSTRACT 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.
