Ascaris Lumbricoides Infestation as an Unexpected Cause of Acute Pancreatitis

Ascariasis is the most common helminthic infection. It is most common in children of tropical and developing countries where the transmission is by contamination of soil by human feces or use of untreated feces as fertilizer. Transmission in most endemic areas is via person to person contact. We hereby present a case report of acute pancreatitis due to ascariasis. Twenty-five-year-old male patient presented to us with chief complaint of acute epigastric pain radiating to back and associated with vomiting. Initial lab investigations revealed increased serum amylase and lipase. Probable diagnosis of acute pancreatitis was made. CT scan was done and report revealed bulky pancreas, and significant peri-pancreatic fat stranding. He was managed symptomatically with intravenous fluids, analgesics, anti-emetics and enteral nutrition. However, the cause remained undetermined as we ruled out the possible etiologies of acute pancreatitis until one day the patient vomited a 15-cm round worm. Thereafter, his condition improved dramatically. This is one of the first few case reports of ascariasis-induced pancreatitis from Pakistan and the first one from Baluchistan province of Pakistan. Thus it highlights ascariasis as possible etiology of acute pancreatitis in regions where ascariasis is geographically endemic.
