Abstract

This chapter discusses the various hepatic diseases that may be encountered as surgical emergencies and provides a detailed description of their preoperative evaluation, surgical techniques, postoperative care, and prognosis. It reviews the basic physiology and hepatic anatomy. By thoroughly understanding the anatomy and physiology, the outcome associated with the majority of pathological processes encountered at surgery can be maximized. Physiologic alteration in the contributions of the portal vein and hepatic artery to total hepatic afferent blood flow is largely a reflection of the hepatic arterial buffer response (HABR), which is discussed in more detail in the chapter. The diagnostic utility of preoperative liver cytology is debatable in the emergency setting. The postoperative management of dogs and cats undergoing emergency surgery of the liver is similar to that of other abdominal procedures. The chapter also discusses specific liver diseases such as hepatic neoplasia, hepatic trauma, liver lobe torsion, and hepatic abscess.
