Abstract
Aim: There is no standard technique for transection of the hepatic parenchyma during robotic liver resection. The
aim of this study was to describe the outcomes of robotic liver resections using the Vessel Sealer for parenchymal
transection.

Methods: This is a post hoc analysis of a prospective database. All consecutive patients who underwent robotic
liver resection in the Regional Academic Cancer Centre, Utrecht, Netherlands, between August 2015 and January
2019 were included.

Results: A total of 70 robotic liver resections were performed, including 60 minor resections (86%) and ten
hemihepatectomies (14%). Five procedures (7%) were converted. Mean parenchymal transection time was 43
± 26 min. Median blood loss was 150 mL (interquartile range 40-300). Ten patients (14%) suffered from a major
complication, and three patients (4%) had bile leakage postoperatively. One patient died from post-hepatectomy
liver failure.

Conclusion: Based on the results of this series, consisting of 60 minor liver resections and 10 hemihepatectomies,
we conclude that the use of the Vessel Sealer during the parenchymal transection in liver resection is feasible and
safe.
