Symptoms of roundworm infection include abdominal pain, nausea and vomiting, loss of appetite, diarrhea or constipation, and teeth grinding in bed.

Ascaris lumbricoides is an invertebrate, Nematoda, Nematoda, Ascaris lumbricoides, Ascaridae. It is the largest parasitic nematode in the human intestinal tract, and the adult body is slightly pink or yellowish, with transverse stripes on the body surface, and the tail of the male worm is often curled. Ascaris lumbricoides is a worldwide distribution species, is the most common human parasite, the infection rate can reach more than 70%, rural than urban, children than adults.

Pediatric roundworm light can be no obvious symptoms, the heavy loss of appetite, or like to eat foreign objects, yellow face shape thin, umbilical abdominal pain, sometimes stopping, touch the soft abdomen, or can be touched to the insect mass scattered, and can be seen to vomit roundworm or roundworm, and dry and sparse stools irregular. Some children appear light-colored white spots, the sclera appear orchid-colored spots, the lower lip or the appearance of granular size of white spots, thin and greasy tongue or flower peeling, tongue tip red tip.

This disease occurs when a child swallows roundworm eggs, and the infection is mainly through contaminated hands or eating unclean food. If the child's spleen and stomach is weak, dietary disorders, the person is more prone to the occurrence of this disease.

When roundworms change their parasitic environment, such as overfeeding, cold, high fever, diarrhea, and improper use of roundworm medicines, it will take advantage of the common bile duct and sphincter due to inflammation, stones and other dysfunctions are in the relaxation of the "upstream", drilling the human body's bile duct. This will cause episodes of severe epigastric colic, and become one of the most common acute abdominal diseases in surgery.

The reason why biliary ascariasis is called acute abdominal disease is that it comes quickly, patients often in the absence of foreboding suddenly occur epigastric "drilling" kind of pain; secondly, the pain is severe, even as a cone stabbing knife strangulation, the patient is often hugging the abdomen and bending the knees, prone to the bed, tossing and turning, pale, and moaning, the patient is often in a state of shock and anxiety. The patient is often in a state of restlessness, pale, sweating, and moaning. Shortly after the abdominal pain, the patient will often appear nausea, vomiting, severe cases can even vomit bile and roundworms. In addition, this kind of abdominal pain is often on and off, although the pain is unbearable, but during the intervals of the patient and quiet as normal. When examined by a doctor, the abdomen is flat and soft, and the pressure pain is slight.

After suffering from this disease, patients and their families should neither panic nor paralyze. It is important to take the time to actively treat, early non-surgical treatment, generally can be cured. If the non-surgical treatment for more than a week still can not be relieved, consideration can be given to surgical treatment, but this treatment belongs to only a small number of people.

The fundamental measure to remove this disease is to prevent roundworms other than, such as usually pay attention to dietary hygiene, must wash hands before meals and after the toilet, in order to prevent the eggs of the worms into other parts of the body. Once found with intestinal roundworm disease, use of anthelmintic drugs must be used in sufficient quantity, so as not to provoke the worm body due to insufficient dosage, triggering the disease.

Common deworming: Commonly used deworming medicines include mebendazole (Amlex), albendazole (intestinal worms), levamisole (to expel roundworms), and piperazine citrate (to expel roundworms, six-one Pagoda Candy), see Commonly Used Deworming Medicines for more details. Because the parasitic survival time of roundworms in the human body is generally about one year, so if you can avoid re-infection, about one year roundworm disease can be "self-cured".

Treatment of biliary ascariasis: The principle of treatment is antispasmodic and pain relief, early deworming and infection control. Early deworming prevents recurrence and complications. Ascaris lumbricoides has acid aversion habit, can use vinegar once 2 ~ 4 two, three times a day, to achieve the purpose of worm. The patient can be treated with surgery for severe hepatobiliary infections if the internal medicine treatment is not effective.

Treatment of Ascaris lumbricoides intestinal obstruction: Most of the Ascaris lumbricoides intestinal obstruction is incomplete, it should be treated early, including fasting, gastrointestinal decompression, spasmodic and analgesic, intravenous rehydration, and deworming after the relief of abdominal pain. When the development of complete intestinal obstruction, complicated by intestinal necrosis, perforation, peritonitis should be timely surgical treatment.
