Abstract

Background:

Ascaris lumbricoides is common intestinal parasite and biliary ascaris is the
commonest extra intestinal manifestation of round worm. This study was aimed to review the
predisposing factors, presentation and the role of endoscopic management of biliary ascaris.

Method:

We performed retrospective analysis of 182 patients diagnosed and admitted as
biliary ascaris in the department of General Surgery, Bangabandhu Sheikh Mujib Medical
University, Dhaka from April 2016 and April 2021. Ultrasonographic findings of abdomen
were the mainstay of diagnosis.

Results:

Biliary ascariasis was more common in female (78%). The most common presentation
was pain (100%). ERCP was done successfully in 90.7%. All patients were given
anthelminthic. There was no complication.

Conclusion:

Ultrasound is a reliable screening test for diagnosis and ERC provides
confirmation. Once diagnosed, endoscopic extraction of the worm is often successful and
provides prompt relief to the patient. Antihelminthics should be administered for eradication
of worms from the intestine and to prevent their reentry into the biliary tree.
