Background :
Ascaris lumbricoides is a common intestinal parasite, and biliary ascariasis is the most common extra-intestinal manifestation of roundworm infection. This study aimed to review the predisposing factors, clinical presentation, and role of endoscopic management in biliary ascariasis.
Method :
A retrospective analysis was performed on 182 patients diagnosed and admitted with biliary ascariasis in the Department of General Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, from April 2016 to April 2021.
Ultrasonographic findings of the abdomen were the mainstay of diagnosis.
Results :
Biliary ascariasis was more common in females (78%). The most common presentation was pain (100%). Endoscopic retrograde cholangiopancreatography (ERCP) was successfully performed in 90.7% of cases. All patients were treated with anthelmintic therapy. No complications were reported.
Conclusion :
Ultrasound is a reliable screening tool for diagnosis, and ERCP provides confirmation. Once diagnosed, endoscopic extraction of the worm is often successful and provides prompt relief. Anthelmintics should be administered to eradicate intestinal worms and prevent recurrence in the biliary tree.
