What procedure involves the excision of a hepatocellular tumor?

Liver resection is the surgical procedure specifically designed for the excision of a hepatocellular tumor. This procedure involves the partial removal of the liver, which is necessary when a tumor is confined to a section of the liver that can be safely removed without compromising liver function.

The liver's unique regenerative ability allows it to regain its volume and function after a segment is removed, making liver resection a viable option for patients with localized liver tumors, such as hepatocellular carcinoma. During this operation, careful assessment of the tumor's size, location, and the liver's overall health is essential to ensure that the remaining liver can adequately support the patient's metabolic needs post-surgery.

In contrast, cholecystectomy involves the removal of the gallbladder, which does not relate to liver tumors specifically. Pancreatectomy pertains to the removal of the pancreas and would not address tumors located in the liver. Abdominal exploration does not describe a specific surgical excision but rather a diagnostic procedure to investigate abdominal organs, which would not focus on the excision of liver tumors. Thus, liver resection stands out as the correct procedure related specifically to the excision of a hepatocellular tumor.
