Abstract
BACKGROUND: Ascariasis in humans is one of the most significant neglected tropical diseases. Usually, the manifestation of ascariasis may vary in each case. In severe cases, ascariasis may lead to intestinal obstruction or perforation of the intestine due to the large number of worms. Here, we report a case of intestinal obstruction due to A. lumbricoides in a 3-year-old boy. CASE PRESENTATION: A 3-year-old Maduranese boy was admitted to the pediatric division with constipation and an enlarged abdomen. During a day of in-hospital observation, the patient vomited worms, which were then identified, and he was diagnosed with ascariasis. The abdominal X-ray showed meteorism with suspected intestinal obstruction. The laboratory test showed anemia and leukocytosis. The exploration laparotomy and ileostomy were performed to extract the worms. The patient was given pyrantel pamoate and albendazole as antiparasitic treatment. CONCLUSION: Intestinal obstruction is a rare manifestation of ascariasis but still should be considered, especially in an endemic area. Detailed anamnesis and comprehensive therapy, including surgery and parasitic treatment, may be beneficial for the patient. Increasing hygiene and taking antihelminthic drugs every 6 months may reduce the infection and complications.
