The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly..

It is formed by the union of the right hepatic duct (which drains bile from the right functional lobe of the liver) and the left hepatic duct (which drains bile from the left functional lobe of the liver). [3] The duct is about 3 cm long. [4] The common hepatic duct is about 6 mm in diameter in adults, with some variation. [5]
On abdominal ultrasonography, the liver can be measured by the maximum dimension on a sagittal plane view through the midclavicular line, which is normally up to 18 cm in adults. [2] It is also possible to measure the cranio-caudal dimension , which is normally up to 15 cm in adults. [ 2 ]
The liver scratch test is a type of auscultatory percussion that uses the difference in sound transmission between solid and hollow organs in the abdominal cavity in order to locate the inferior edge of the liver. [3] [4] [1] The test is most commonly performed by placing the stethoscope below the xiphoid process and lightly scratching the skin ...

At birth, the liver comprises roughly 4% of body weight and weighs on average about 120 g (4 oz). Over the course of further development, it will increase to 1.4–1.6 kg (3.1–3.5 lb) but will only take up 2.5–3.5% of body weight. [40] Hepatosomatic index (HSI) is the ratio of liver weight to body weight. [41]
