Robotic central hepatectomy for hepatocarcinoma by glissonean approach (with video)

Central bisegmentectomy of the liver implies excising Couinaud's segments IV, V and VIII (Couinaud and Le Foie, 1957) [1]. In a recent classification of laparoscopic liver resections, it belongs to the highly advanced level procedure group (Kawaguchi and et al., 2018 Jan) [2]. Improvement in laparoscopic devices should lead to a wider accessibility of such indications that are currently expert prerogatives. In order to illustrate the assets of robotic-assistance in the management of highly difficult mini-invasive hepatic resections, we present the case of a robotic central hepatectomy.

This video illustrates robotic central hepatectomy in a 70-year-old male. A liver tumor involving segments IV, V and VIII was incidentally detected during abdominal ultrasonography. CT scan and MRI suggested the diagnosis of a seventy-millimeter centrally located hepatocellular carcinoma and surgical resection was decided.

The patient was placed supine in anti-Trendelenburg position. Four robotic trocars were placed and the da Vinci X robotic system was docked. Two laparoscopic ports were placed for the second surgeon (ultrasonic dissector and suction/irrigation set). Central hepatectomy was performed with a glissonean approach. Robotic irrigated bipolar coagulation and laparoscopic ultrasonic dissector was used for parenchymal transection. Postoperative course was uneventful. The patient was discharged on postoperative day eight.

The recent publication of an International consensus statement demonstrates the growing involvement of robotics in liver surgery (Liu and et al., 2019 March 28) [3]. Robotic advantages (flexibility, absence of fulcrum effect and visual field stability) could improve accessibility to minimal invasive approach for difficult liver resection.
