Circulation in the liver is unique because of a dual afferent blood supply, derived from the hepatic artery (HA) and the portal vein (PV; see Chapter 2 ). The oxygen-rich arterial blood and the nutrient-rich PV blood merge in the…
The limits of hepatic resectability are constantly expanding with our increased understanding of hepatic anatomy and refinements in surgical technique (see Chapters 2 , 102 , and 118B ). In past years, partial hepatectomy was limited to anatomic resection and…
The pancreas is a complex retroperitoneal gland with both endocrine (e.g., glucose homeostasis) and exocrine (e.g., nutrient digestion) functions. An adult human pancreas measures approximately 15 cm in length and weighs between 60 to 100 g; however, its size can…
Anatomy overview Precise knowledge of the architecture of the liver, biliary tract, and pancreas and the related blood vessels and lymphatic drainage is essential for the successful performance of hepatopancreaticobiliary surgical operations. Liver The liver lies protected under the lower…
Introduction The liver’s essential structure is one of layers of metabolically active hepatocytes arrayed along and around a vascular network carrying nutrient-rich blood derived from the products of intestinal absorption, otherwise semi-isolated from the systemic circulation. The biliary ducts are…
