Technical tricks for radical but conservative liver resection. The ultrasound guidance

Rate of major resection is still high in most surgical institutions due to fear of incomplete tumor removal: this is in spite mortality and major morbidity of major hepatectomies, particularly in cirrhotic are still not negligible. Intraoperative ultrasonography (IOUS), when used not only for tumor staging but also for resection guidance, minimises the rate of major hepatectomies maintaining treatment radicality. Maintaining this policy, the rate of major resection in our experience is 15% if major hepatectomy is classified as removal of at least 1 sector or 2 adjacent segments, and 5% if we consider major resections only those which include at least 3 segments. This policy has allowed us a safe surgical approach with no mortality and minimal major morbidity and effective local treatment with no tumor relapses at the site of the resection after a mean follow-up of 18 months. Tricks for safe and radical IOUS-guided liver resections are here discussed.
