If you have a habit of eating fish, please do an ultrasound scan
Although the raw fish made from fatty catfish is refreshing and sweet, numerous white liver fluke eggs may be hidden in the white fish fillets. Once these eggs enter the body, their adult parasites will develop and reproduce in the bile ducts of humans.And constantly excrete metabolites and secrete toxic substances, damage the liver.
Experts from the Guangdong Provincial Center for Disease Control and Prevention remind that freshwater fish in the Pearl River Basin of Guangdong Province are generally infected with liver flukes, so do n’t be lucky. You should stop eating all fish made from freshwater fish.
The highest infection rate among fishermen and merchants is that liver fluke disease is currently one of the most serious food-borne parasitic diseases. The human parasite epidemic survey released by the Ministry of Health in May 2005 showed that there were about 12 million people infected with liver fluke.That’s a 75% increase from 15 years ago.
Among them, Guangdong, Guangxi, and Jilin provinces (regions) increased by 182%, 164%, and 630%, respectively.
The survey also showed that the infection rate of all kinds of people increased as the chance of eating “fish raw” increased.
Cantonese people are highly susceptible to liver flukes due to their hobby.
The Guangdong Provincial Center for Disease Control and Prevention has conducted a sample survey of 9 counties (cities) in the province. Among 13,876 people, the average infection of liver fluke disease was 16.
42%, especially the majority of adult males.
The survey also found that fishermen and businessmen were most affected, with an infection rate as high as 32.
Fang Yueyi, a department of endemic disease prevention and control of the Guangdong Provincial Center for Disease Control and Prevention, pointed out that freshwater fish in the Pearl River Basin were generally infected by liver fluke cysts.
Therefore, when the fish is grilled, grilled, scalded or steamed, if the temperature is insufficient, the time is insufficient, or the fish is too thick, it may not kill all the cysts.
The liver fluke cysts in fish can even cross-infect with baffles, kitchen knives, dishes, dishes, and chopsticks, and then enter the population to infect people with liver flukes.
Liver fluke disease is easily misdiagnosed. Adult parasites missed from liver fluke are found in the bile ducts of humans, with a life span of 20-30 years. Complications continue to grow and reproduce, and release a large number of metabolites and toxic substances, harming the human body.
Infected patients will repeatedly experience fatigue, poor appetite, yellow urine, fever, accompanied by right upper quadrant pain, liver discomfort, and dull pain.
Due to the slight involvement of the hepatobiliary system, as well as systemic symptoms and signs, it is easy to cause misdiagnosis and missed diagnosis.
The Department of Liver Diseases of the Eighth People’s Hospital of Guangzhou City has investigated the 102 cases of liver fluke patients they saw and found that too many of these patients have been misdiagnosed as hepatitis, infectious disease, and obstructive jaundice, and their misdiagnosis rates were 50%, 13.
76%, 83 were misdiagnosed.
”There are no obvious symptoms of liver fluke infection early, and after a few years, most patients will develop liver damage.
“Zhang Chunlan, director of the First Division of Liver Diseases, also said,” Liver fibrosis exists at different levels at different stages of liver fluke disease. Some patients have improved liver fibrosis after deworming treatment, but there are also no changes.
To prevent “worms”, the development of freshwater fish and shrimp liver fluke larvae needs to pass through two intermediate hosts. The first intermediate host is snails (Snails, snails, etc.); the second intermediate host is various freshwater fish and shrimp.
Among them, catfish is often the host with the highest infection with liver fluke.
In areas with a high incidence of liver fluke disease, the following dietary habits are the most likely to give worm eggs the opportunity to invade the human body: ① raw or undercooked: For example, residents of the Pearl River Delta region like “fish raw” or “raw roll fish porridge”; ChaoshanPeople like drunk shrimp drunk crabs (marinated with vinegar or wine); Northeast Korean residents are accustomed to using raw fish to serve wine; residents of Jiangsu and Zhejiang like live shrimp and live fish.
② Improper handling of raw and cooked food: raw and cooked food is not distinguished when handling food, and bursa contaminates food through cutting boards, kitchen knives, tableware, etc., thereby causing infection.
Humans eat live liver fluke cysts, and after 1 month, the cysts develop into adults and parasitize in the human liver and bile ducts.
Therefore, in order to prevent liver fluke disease, the habit of eating raw fish should be actively changed.
Experiments have shown that cysts in fish fillets with a thickness of about 1 mm can die in 1 second in hot water at 90 ° C, and die within 3 seconds at 75 ° C.
Tip: Have a fish eating habit, do a B-ultrasound. If you have a fish eating habit before, it is recommended to have a liver function test and liver B-ultrasound.
For patients with liver fluke, anti-infective treatment and deworming treatment are needed.
At present, pyrrolidone is the drug of choice for treating liver fluke. After deworming treatment, liver function returns to normal within 3-4 days.
Severely infected persons with malnutrition or cirrhosis should strengthen nutrition, protect the liver, and then consider special treatment.
Patients with acute surgical complications such as cholecystitis and common bile duct intervention require surgical treatment.
