Conformational technique for non-anatomic resection of liver lesions

Safe margin-negative hepatic resection with maximal preservation of normal liver parenchyma is the primary operative objective in treating patients with metastatic or primary liver malignancies. A technique to perform non-anatomic liver resection(s) for large lesions that may involve major hepatic vascular structures is herein described. This technique employs linear cutting stapler technology and specific mobilization of the liver to perform single or multiple large spherical resections of liver lesions.
