Parasitic liver cysts clinically refer to liverworm disease, which is clinically contagious and occurs mainly in the western regions of our country where animal husbandry is more developed. How are the parasites of liver cysts transmitted? Clinically, parasitic liver cysts mainly include two types of liver cystic encystasis caused by Echinococcus granulosus and hepatic vesicular encystasis caused by Echinococcus multilocularis infection. Clinically, Echinococcus granulosus is most common. Echinococcus granulosus is parasitic in the intestinal tract of dogs, and the parasite’s eggs can be found in grasslands and water sources with the dog’s fecal pastures. If a person is unfortunately infected by the eggs, the eggs can hatch into larvae in the human gastrointestinal tract and flow into the portal vein with the small vein confluence, which can make the eggs of the worm, stay in the liver for a long time. Most patients with parasitic liver cysts have no obvious clinical symptoms in the early stage, but when the bile ducts are blocked at a later stage, the patient may develop obstructive jaundice. At this time, patients go to the hospital, the effect of treatment at this time is poor. The liver cyst caused in the package can be divided into internal and external cysts, and the cystic fluid appears colorless and transparent, some patients if the cystic wall rupture can cause the cystic contents to spill, causing serious allergic reactions. It can also cause the spread of parasites in the abdominal cavity, so it is necessary to maintain the integrity of the cyst wall when surgically removing parasitic liver cysts to avoid serious complications caused by cyst wall rupture. Most patients with parasitic liver cysts are mainly treated surgically and often achieve better results.
