Abstract
BACKGROUND: Blood loss is a major determinant of outcomes following hepatectomy. Robotic technology enables hepatobiliary surgeons to mimic open techniques for inflow control and parenchymal transection during major hepatectomy, increasing the ability to minimize blood loss and perform safe liver resections. METHODS: Initial experience of 20 consecutive major robotic hepatectomies from November 2018 to July 2020 at two co-located institutions was reviewed. All cases were performed with extrahepatic inflow control and parenchymal transection with the laparoscopic cavitron ultrasonic surgical aspirator (CUSA), and a technical description is illustrated. Clinical characteristics, operative data, and surgical outcomes were retrospectively analyzed. RESULTS: The median (range) patient age was 58 years (20-76) and the majority of 14 (70%) patients were ASA III-IV. There were 12 (60%) resections for malignancy and the median tumor size was 6.2 cm (1.2-14.6). Right or extended right hepatectomy was the most common procedure (12 or 60% of cases). There were 7 (35%) left or extended left hepatectomies and 1 (5%) central hepatectomy. The median operative time was 420 (177-622) minutes. Median estimated blood loss was 300 mL (25-800 mL). One (5%) case was converted to open. Two (10%) patients required blood transfusion. The median length of stay was 3 (1-6) days. Major complications included 1 (5%) Clavien-Dindo IIIa bile leak requiring percutaneous drainage placement. There was no 90-day mortality. CONCLUSION: Advanced techniques to reduce blood loss in robotic hepatectomy may optimize safety and minimize morbidity in these complex minimally invasive procedures.
