The 1.9 centimeters under the sword of the liver should generally be taken to mean that the liver extends 1.9 centimeters beyond the lower edge of the xiphoid process. In normal adults, most of the body of the liver is located under the right side of the costal arch, and a small portion of the liver crosses the epigastric raphe and is located under the left side of the costal arch. Usually, the inferior border of the liver is not palpable, but in a few people, the inferior border of the liver may be palpable under the costal margin with deep inhalation, mostly no more than 1 cm. In a few cases, the subhepatic border can be touched under the rib cage with deep inspiration, but not more than 1 centimeter. The rib arches on both sides and the sternum form the angle of the rib arches, and the lowermost tip of the median sternum is called the raphe, which is about 2 centimeters in length, and if we add 1.9 centimeters under the raphe, it equals to 3.9 centimeters under the root of the raphe, which is basically within the normal range. There are many reasons for hepatomegaly, mainly infectious and non-infectious. When you find enlarged liver or related symptoms, you need to consult a doctor in time.
