Laparoscopic Management of Hepatocellular Carcinoma: A Critical Reappraisal
Abstract
Following the introduction of the first laparoscopic liver resection, after ∼25 years, a critical reappraisal seems to be warranted. Liver resection represents the first choice for curing early hepatocellular carcinoma (HCC) allowing a curative chance also in selected patients with intermediate stage tumors. The criteria for liver resectability by laparoscopy remains the same for open surgery, which is oncological criteria (absence of extrahepatic tumor location; completely resectable R0 resection), anatomic (resectability of involved segment with its own blood surely and biliary drainage; absence of vascular invasion of portal or hepatic veins) and technical (possibility to leave in place a residual volume ≥40%). Anatomic resections being more challenging than wedged resections, were initially performed mainly for lesions located in the left liver (segments 2, 3, and 4) and segments 5 and 6 of the right liver (anterior and lateral hepatic segments). Left lateral segmentectomy seemed most suited for laparoscopic resection because of the thinness of the liver, the possibility of resection without hilar dissection, ease of stapling the left hepatic vein and portal pedicles of segment II and III by mechanical stapling. Conversely,...Continue Reading
