Abstract
Background/Aim: Ascariasis is endemic in the tropics especially amongst those living in poor sanitary conditions. Although most commonly it infests the small intestine, it can sometimes migrate to the biliary tract. We herein aimed to study the clinical manifestations, complications, diagnostic modalities and the most appropriate treatment modality for this condition.
Materials and Methods: Fifteen cases of hepatobiliary ascariasis presenting over a period of 1.5 years were studied. All the patients were adults and presented to the emergency with acute biliary symptoms.
Results: In this study, biliary ascariasis was found to be more common in middle aged females. The common presentations included upper abdominal pain and jaundice. Complications observed included acute pancreatitis and cholangitis. Ultrasonography could establish the diagnosis in 86.67% cases. Medical management could successfully treat 86.67 % patients with ERCP being required in the remainder.
Conclusion: In endemic countries, ascariasis should be considered as a differential diagnosis in patients presenting with acute biliary symptoms. Ultrasonography is a useful non invasive test to diagnose the condition and medical management remains a reasonable first line treatment option.
