[사진=뉴욕포스트 보도 캡처]A ‘monstrous creature’ reminiscent of the movie ‘Alien’ was discovered in the abdomen of a 70-year-old man. It looks like a parasite wriggling like a worm inside an apple.
According to reports such as the Daily Mail in the UK and the New York Post in the US, a 70-year-old man was admitted to a hospital in China and underwent a cholecystoscopy. Medical staff inserted a camera through the mouth and skin to examine problems in the upper abdomen.
Doctors found a tumor in the intestines of the man, who had a history of colon cancer, but that was not all. During the examination, five broad, leaf-shaped worms were found writhing in his bile duct. The biliary tract is an organ that transports digestive juices from the liver to the small intestine.
The digestive parasite was identified as clonorchis sinensis, a type of liver fluke found in uncooked fish and shrimp, according to the U.S. Centers for Disease Control and Prevention.
This liver fluke, which is 10 to 25 mm long and 35 mm wide, can usually live in the human body for about 3 to 4 years, and can survive for up to 20 to 30 years. It is commonly found in regions such as Korea, China, Vietnam, Cambodia, and Laos, where raw fish and seafood are commonly consumed.
When a person eats contaminated fish, the larvae move into the bile ducts and grow into adults. Liver flukes that enter the human body grow in the duodenum connected to the stomach, then move upward along the bile duct connected to the duodenum and become adults in the middle part of the bile duct. It takes 3 to 4 weeks after infection for the worms to become adults, and the eggs laid by the adult worms are excreted through the feces along with bile, and this cycle is repeated.
Even if infected with liver fluke, there are no symptoms in most cases, so patients often do not know that they have parasites. If left untreated, it can cause complications ranging from bacterial infections to pancreatitis and liver abscesses.
After removing parasites from the man’s biliary tract, medical staff prescribed medication for the infection. He is receiving chemotherapy to fight cancer. The story was recently reported in the New England Journal of Medicine.
