Presentation of Ascariasis as a Cause of Acute Intestinal Obstruction.

Ascariasis infection is prevalent in tropical and subtropical locations worldwide. The occurrence of ascariasis is associated with poverty, inadequate hygiene, and inadequate fecal sanitation. This helminth often resides innocuously in the small intestine, but it may sometimes lead to intestinal blockage or perforation, resulting in peritonitis, a condition frequently seen in children. Ascariasis may also migrate via the ampulla of Vater, leading to the development of cholangitis, pancreatitis, cholecystitis, and, in rare cases, hepatic abscesses. Occasionally, an Ascaris-induced hepatic abscess may manifest as an acute abdomen, resembling an acute pyogenic abscess. We report the case of a four-and-a-half-year-old male child from Khedi Sikarpur, Haridwar, India, who was admitted to the pediatric department. The patient presented with acute colicky abdominal pain localized to the abdomen, accompanied by vomiting and constipation for three days. Additionally, the patient experienced abdominal distension for one day. There was no history of bleeding manifestations or decreased urine output.
