One of the most important organs of the human body is the liver. It receives about one and a half liters of blood per minute and is a participant in three vital functions of the organism: purification, synthesis and storage.
Solid hepatic lesions
In the liver can occur different types of tumors, benign or malignant. However, in order to study liver tumors it is key to determine if the liver tissue is healthy or damaged.The most frequent solid liver lesions are:- Adenoma: is a benign tumor that usually appears in young women, being a risk factor the use of oral contraceptives for a long period of time. When they are big, they must be intervened for the risk of bleeding.- Hemangioma: is the most frequent liver tumor and is benign. They are usually detected by CT or ultrasound and are asymptomatic.- Metastasis: they are implants tumor originating of a cancer originated in another part of the body. It is the most frequent malignant liver tumor, and they emphasize the digestive ones, like the colon, the pancreas or the stomach. Depending on where it is located, liver metastases associated with colon cancer can be operated.- Hepatocarcinoma: this is the most frequent cancer associated with the liver, and usually appears on cirrhotic livers.Liver surgery involves the excision of the affected part, sometimes requiring resection of a complete hepatic lobe. Currently, this procedure is performed by laparoscopy by a specialist in General Surgery.
Types of cysts in the liver
- Simple hepatic cyst: these are imperceptible, fluid-filled structures that are not communicated with the bile duct. Their size is variable, and may be either single or multiple, and appear more frequently in women. They are usually asymptomatic, and do not require treatment, although if they complicate (hemorrhage, rupture ...) it indicates surgery, usually laparoscopic surgery.
- Hydatid cyst: are cysts that are produced by the larval forms of a parasite that inhabits dogs and that expels its cystic larvae through feces. It is the parasitic disease that affects most people. They can affect other organs and can be either single or multiple. The treatment consists of the complete removal of the cyst.
