Abstract
BACKGROUND: 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. OBJECTIVE: The aim of this article was to introduce a safe and effective approach to paracaval liver segments through laparoscopy. METHODS: 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. RESULTS: Postoperative courses were uneventful, and patients were discharged on postoperative day 3. DISCUSSION: The approach to paracaval liver segments requires accurate preoperative case selection, technical, surgical, and anesthesiological expertise in laparoscopic liver surgery, and adequate instrumentary. CONCLUSION: 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.
