Liver: lobectomy

Synonym(s): Hepatic lobectomy and biopsy

Contributor(s): Andrew Gardiner, Kathryn Pratschke

Introduction

  • Liver lobectomy involves surgical removal of a liver lobe. The term massive hepatectomy is used where two or more lobes are resected in one procedure.
  • Partial lobectomy implies removal of part of the lobe, sometimes referred to as subtotal lobectomy.
  • Liver biopsy involves obtaining one or more samples for laboratory analysis including histology, copper analysis, and microbiology. Biopsy may be single or multiple.

Uses

Advantages

  • Direct visualization and palpation of the entire liver is possible.
  • Biopsy or resection of clinically relevant areas in focal hepatic disease can be assured.
  • If hemorrhage occurs at a biopsy site it can be readily managed.
  • If neoplastic disease is present the abdomen can be examined and additional samples obtained if necessary for complete surgical staging.

Disadvantages

  • Animals suffering from hepatic disease may be poor anesthetic and surgical risks.
The risk of hemorrhage always exists with hepatic surgery; thorough patient evaluation pre-operatively is mandatory.
  • Intensive care facilities and staffing are required for major hepatic surgery.

Prognosis

  • The prognosis depends on the underlying problem and whether this is amenable to medical treatment. Where there is diffuse progressive disease, unfortunately clinical signs are often manifested late in the course of disease, so the prognosis for many of these patients will be guarded.
  • The most common liver tumor is hepatocellular carcinoma Liver: hepatocellular carcinoma; the prognosis is good for the focal type, but poor for nodular and diffuse.
  • Outlook for traumatic lesions requiring partial or complete lobectomy is influenced by other injuries present and patient status.
