How is intestinal Ascaris infection to return a responsibility?

summary

Ascariasis is the most common intestinal parasitic disease. The source of infection is ascariasis patients and infected persons. A large number of eggs were excreted with the patient's feces, contaminating vegetables and soil. Under the appropriate temperature and humidity, after about 2 weeks, they developed into mature eggs. How is intestinal Ascaris infection to return a responsibility? Next, I'd like to share my views with you.

How is intestinal Ascaris infection to return a responsibility?

Ascaris lumbricoides adults parasitize the middle and lower segments of the small intestine and occasionally enter the upper digestive tract. Roundworms have a habit of drilling holes. Therefore, Ascaris lumbricoides entering the duodenum often enter the biliary tract through the common bile duct opening. Clinical observation has noticed that sometimes Ascaris can be vomited or crawled out through the mouth, and the patients are often accompanied by high fever, hunger, diarrhea or insufficient dosage due to the use of shandaonian. Therefore, the change of Ascaris lumbricoides living environment may be the inducement to promote the movement of Ascaris lumbricoides to the upper digestive tract.

In the process of Ascaris lumbricoides passing through the sphincter of Oddi, the sphincter spasms due to stimulation, causing severe pain. When Ascaris lumbricoides exited or completely entered biliary tract, the stimulation to sphincter disappeared and the severe pain caused by spasm was relieved. Ascaris lumbricoides can also cause paroxysmal pain in biliary tract. Because of the activity of Ascaris lumbricoides, the passage of bile is not blocked completely, so jaundice does not appear. When intestinal bacteria enter the biliary tract with the worm, they can cause biliary tract infection, acute inflammation of gallbladder and bile duct, leading to liver abscess, hemobilia, septic shock and septicemia.

On the other hand, we can clearly see that the Ascaris lumbricoides bodies in the biliary tract were gradually embedded by gallstone like precipitation, and finally formed stones in various stages. In addition, Ascaris lumbricoides remains or eggs can be found in the core of cholelithiasis in 40% - 84% of cases. It can be seen that after the abdominal pain symptoms of biliary ascariasis are relieved, some patients can remove the dead worms in the biliary tract without sequelae.

matters needing attention

In order to reduce the incidence of biliary ascariasis, we should strengthen the health propaganda, do a good job in the harmless management of feces, pay attention to diet hygiene, and do not eat raw, cold and unclean food, so as to cut off the source of infection and reduce the infection rate of intestinal ascariasis.
