Technique of robotic right donor hepatectomy

Although minimally invasive right donor hepatectomy (RDH) has been reported, this innovation is yet to be widely accepted by transplant community. Bleeding during transection, division of right hepatic duct (RHD), suturing of donor duct as well as retrieval with minimal warm ischemia are the primary concerns of most donor surgeons. We describe our simplified technique of robotic RDH evolved over 144 cases.Right lobe mobilization is performed in a clockwise manner from right triangular ligament over inferior vena cavae up to hepatocaval ligament. Transection is initiated using a combination of bipolar diathermy and monopolar shears controlled by console surgeon working in tandem with lap CUSA operated by assistant surgeon. With the guidance of indocyanine green cholangiography, RHD is divided with robotic endowrist scissors (Potts), and remnant duct is sutured with 6-0 PDS. Final posterior liver transection is completed caudocranial without hanging manoeuvre. Right lobe with intact vascular pedicle is placed in a bag, vascular structures then divided, and retrieved through Pfannenstiel incision.Our technique may be easy to adapt with the available robotic instruments. Further innovation of robotic platform with liver friendly devices could make robotic RDH the standard of care in future.
