The appearance of white worms in the buttocks is a typical symptom of ascariasis, which should be promptly treated with intestinal wormer for laxatives. The appearance of ascariasis is mainly caused by the usual unhygienic diet and the lack of attention to personal hygiene, resulting in fecal-oral transmission. First of all, for simple intestinal roundworm disease and no obvious complications, you can take oral albendazole, mebendazole and other drugs for treatment, these drugs have very good deworming efficacy. Secondly, if the patient has other complications caused by ascariasis or combined with the appearance of other infectious diseases, intestinal obstruction caused by ascariasis is the main representative. Patients often show symptoms of abdominal pain, diarrhea, as well as nausea and vomiting, and in serious cases, the anus will not be able to defecate or ventilate normally, and the intestinal canal needs to be cut open for worm extraction, and if the intestinal canal becomes necrotic, it needs to be removed.
