Liver cyst cut inside is some viscous fluid or jelly-like stuff. The fluid inside the liver cyst is viscous, usually colorless, yellowish, containing a small amount of protein, red blood cells and bilirubin, etc. Jelly-like stuff is usually caused by inflammation of the hepatic ducts. Liver cysts are a benign disease. If the cysts are small, no special treatment is needed and regular checkups are sufficient. If the cysts are large and present a series of symptoms, such as pain, jaundice, etc., early surgical treatment can be taken. Patients with liver cysts should follow the doctor’s instructions and choose the appropriate treatment method.
