Parenchymal preserving liver resection for centrally located liver tumors: how I do it?

Central liver tumors often require extended hepatectomy or a central hepatectomy with complex biliary reconstructions. Extended resections are prone to higher chances of post-operative liver failure, while the resections mandating reconstructions run a risk of biliary leaks. Non-anatomical liver resections for these centrally located tumors provide a benefit of functional parenchymal preservation but a higher perceived risk of oncological inadequacy. This manuscript is an attempt to showcase author's technique of parenchymal sparing liver resection for central located liver tumor without the need for any biliary reconstruction while ensuring oncological adequacy during the conduct of the procedure.
