nonparasitic liver cyst
Introduction
Introduction to non-parasitic hepatic cysts The majority of non-parasitic hepatic cysts are benign diseases of the liver, of which congenital cysts are the most common. The disease can be single or multiple. Multiple hepatic cysts are often associated with polycystic lesions of the kidney, pancreas, ovaries, lungs, etc. Non-parasitic hepatic cysts can be classified according to the cause: congenital cysts (isolated or single, diffuse or multiple) Sexual cysts; inflammatory cysts; retention cysts; neoplastic cysts (dermoid cysts, cystadenomas, cysts formed by malignant tumor degeneration). basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: abdominal pain
Cause
Causes of non-parasitic hepatic cysts
Hepatic cysts are mostly congenital and are caused by intrahepatic bile duct or lymphatic developmental disorders. During embryonic development, excess bile ducts degenerate without connecting with distal bile ducts; if excess bile ducts in the liver are not degraded and absorbed, gradually It is divided into segments and cysts to form cysts. Polycystic liver is often accompanied by polycystic kidney, pancreatic cysts, lung or spleen cysts and other malformations. It can also be used as evidence for congenital dysplasia. Polycystic liver can occur in the same Different members of the family, and thus the occurrence of polycystic liver disease may be related to chromosomal recessive inheritance. The occurrence of a single hepatic cyst is attributed to the ectopic bile duct, which is thought to originate from the bile duct or congenital liver in the vagus distortion of the liver. The biliary epithelial hyperplasia is occluded, resulting in the stagnation of the contents of the lumen.
Prevention

Efficacy evaluation
1. Cure: Symptoms disappear, B-review cyst disappeared.
2. Better: The symptoms are alleviated, and the B-review cyst is reduced.
3. No change: the symptoms are still there, B-ultrasound shows that the cyst does not shrink.
Expert tips
This disease is a congenital benign lesion, there is no effective drug treatment at present, so patients should not be convinced that the travel doctor has a "secret recipe" can be cured, the general cyst <5cm, and no symptoms, can not be treated, such as > 5cm, and have symptoms, Should go to the hospital for treatment, after all, the disease has a certain rate of malignant transformation, even if not treated, regular follow-up B-review.
Complication
Non-parasitic hepatic cyst complications Complications, abdominal pain
1. Intracapsular hemorrhage.
2. Cyst rupture or infection.
3. The cyst is twisted and causes severe abdominal pain.
Symptom
Symptoms of non-parasitic hepatic cysts Common symptoms Internal bleeding, abdominal discomfort, cysts, swelling of the liver
Clinical manifestations:
Small cysts have no obvious symptoms, and it is difficult to make a diagnosis. It is often found in physical examinations and abdominal surgery. When the cysts are large, there may be discomfort in the right upper quadrant, dull pain, feeling of fullness after meals, liver enlargement and mass in the right upper abdomen. The capsule is sexy and has no obvious tenderness. The liver surface of the multiple hepatic cyst can touch the scattered cystic nodules, such as intracapsular hemorrhage, combined infection or pedicle cyst torsion, may have acute abdominal performance.
Examine
Non-parasitic liver cyst examination
1. The Casson test is positive.
2. B-mode ultrasound can determine the size, location and number of cysts.
3. Liver nucleus scanning liver area can show space-occupying lesions (cell diameter > 2 ~ 3cm).
4. X-ray examination often shows signs of increased liver shadow, increased diaphragm and pressure shift of the gastrointestinal tract.
5. CT examination is helpful for diagnosis and differential diagnosis.
Diagnosis
Diagnosis and identification of non-parasitic hepatic cysts
diagnosis
It can be diagnosed based on medical history, clinical symptoms and laboratory tests.
Differential diagnosis
1 Hepatic hydatid cyst: There is often a positive history of the worm skin test in the infected area.
2 liver abscess: there is inflammation, often history of purulent disease or dysentery, ultrasound imaging showed no clear thin wall, there is inflammation around the liquid occupying place.
3 large tumor central liquefaction: ultrasound can be seen in the lesion at the same time liquid and substantial occupying.
