Abstract
A dramatic spread of laparoscopic liver surgery has been experienced over the last years. The approach to paracaval liver segments 1 and 9 is still poorly described in literature, mainly due to its technical demands. The aim of this article was to introduce a safe and effective approach to paracaval liver segments through laparoscopy. A minimally invasive approach to resection of Segments 1 and 9 is presented, and an operative set-up is depicted. A step-by-step technique describing the inferior vena cava (IVC) with left and right hepatic venous junction exposure, segmental pedicle isolation, and parenchymal transection is shown through a video document. Postoperative courses were uneventful, and patients were discharged on postoperative day3. The approach to paracaval liver segments requires accurate preoperative case selection, technical, surgical, and anesthesiological expertise in laparoscopic liver surgery, and adequate instrumentary. Paracaval segments of the liver can be approached safely through laparoscopy by teams with extensive expertise in the field of laparoscopic liver surgery; however, suspected malignant infiltration of the IVC or unclear preoperative anatomy still contraindicate this approach.
