Laparoscopic versus open liver resection for hepatocellular carcinoma in posterosuperior segments.

Background Traditional open liver resection remains the classic procedure for hepatocellular carcinoma (HCC) located in the posterosuperior segments of the liver (segments I, IVa, VII, and VIII). This study compared the perioperative and oncologic results for laparoscopic versus open liver resection of HCC located in the posterosuperior segments, especially in patients with cirrhosis.
