The common point of the liver cyst is that it is the blister in the liver. Most of the hepatic cysts are congenital, which causes the formation of hepatic cysts due to some abnormalities of the congenital development. The liver cyst has abdominal pain, vomiting and jaundice. So how does the liver cyst form? What are the clinical manifestations of hepatic cysts?
Multiple hepatic cyst is a dominant genetic disease, father or mother have multiple cysts, the child may develop, but mostly after the age of 40, will be sent. Multiple hepatic cyst size, a small cm below, large there are more than 15 centimeters. The number number is not clear. It is worth noting that 50% of the patients with multiple hepatic cysts also have multiple renal cysts, which eventually lead to complications such as hematuria, hypertension, renal failure, uremia and so on.
Multiple cysts may increase with age, showing a growing trend of more and more days. When big and long because of cyst, hepatomegaly, and abdominal distention, abdominal pain, nausea, vomiting and other symptoms.
What are the common causes of liver cyst disease?
1, single hepatic cyst
Different sizes, from several millimeters to more than 20 centimeters in diameter, can occupy the whole liver. The cysts were round, oval, mostly single, with multiple or pedicled cysts. The capsule is intact, its surface is milky white or gray, the thickness of the cyst wall is 0.5~5 millimeter, the liquid in the capsule is transparent, it has brown color when bleeding or bile, and contains a small amount of albumin, mucin, cholesterol, red blood cells, bilirubin and so on.
2, multiple hepatic cysts and liver
The size of the cyst is different, the maximum capacity of the cyst is more than 1000 milliliters, such as the size of sesame and mung bean, the cyst is scattered all over the liver or a certain liver leaf, and the right lobe is more common. The general section is honeycomb, and the cavity contains clear clear liquid and no bile. When hepatic cyst is very large, it can oppress liver cells and cause atrophy. It can cause bile duct stricture, cause cholecystitis, cause liver function damage, and finally appear ascites, jaundice or even esophageal varices.
What are the symptoms of liver cysts?
1, gastrointestinal symptoms of early asymptomatic congenital liver cysts, clinical diagnosis is difficult, in recent years by ultrasound examination showed that the cyst growth, usually 40~50 years after the onset of symptoms, the cyst grows to a certain extent compression of adjacent organs, can appear abdominal discomfort, pain and symptoms of digestive tract.
2, fever a few cysts rupture, intracapsular hemorrhage, with pedicle cyst torsion can appear acute abdomen. Capsule infection have chills, fever, leukocytosis, physical examination can have liver or abdominal mass. The growth of hepatic cysts is slow, and most of the patients have no obvious symptoms.
3, abdominal pain when the cyst grows up to a certain extent, can oppress adjacent organs, such as the stomach, duodenum and colon, common bloating after eating, poor appetite, nausea, vomiting, abdominal discomfort and vague pain and other symptoms.
What are the hazards of liver cysts to patients?
The liver cyst is a more common benign disease of the liver, which can be divided into parasitic, non parasitic and Congenital heredity, experts say. Most of the pathogenesis of hepatic cysts is the development of small bile ducts in the liver, and the occurrence of single hepatic cysts is caused by ectopic bile duct. The growth of hepatic cysts is slow, so it may be asymptomatic for a long or lifetime. Its clinical manifestations vary with the location, size and number of cysts, and whether the adjacent organs are involved or not.
In addition, hepatic cyst is a benign mass, often associated with cysts of other organs, such as polycystic kidney. Most patients with liver cysts have no obvious symptoms. Generally speaking, patients with liver cysts that have no obvious symptoms or normal liver function can not be treated. But if the symptoms are intolerant, or the liver function has been affected, the consequences are very serious.
Experts remind that about 50% of patients with liver cysts combined with polycystic kidney can have symptoms of hypertension, hematuria, kidney pain and renal dysfunction. The risk of hepatic cyst is complicated by cyst infection, bleeding, rupture and torsion. It is characterized by sudden abdominal pain, hyperthermia or symptoms and signs of peritonitis.
At the same time, liver cyst can appear liver pain, abdominal distention, sometimes cyst sudden enlargement or secondary infection, can suddenly increase abdominal pain, or fever. Sometimes the upper abdomen can touch the masses, and some patients have abdominal pain, vomiting, and jaundice.
