Summary
A rare case of biliary ascariasis in Korea involved a woman whose gallstones were formed from a dead roundworm (Ascaris lumbricoides). This finding highlights a unique cause of cholelithiasis and parasitic infection.
Area of Science:
- Hepatology
- Parasitology
- Gastroenterology
Background:
- Biliary ascariasis, a parasitic infection of the bile ducts by Ascaris lumbricoides, is uncommon, particularly in regions with improved sanitation.
- Cholelithiasis (gallstones) is a common condition, but its formation secondary to parasitic infestation is rare.
Observation:
- A 43-year-old Korean woman presented with abdominal pain, nausea, and vomiting, indicative of biliary tract issues.
- During cholecystectomy, biliary stones were retrieved from the left hepatic duct.
- These stones contained remnants of Ascaris lumbricoides, including cuticle and eggs.
Findings:
- The retrieved biliary stones were composed of degenerated Ascaris lumbricoides components, strongly suggesting they formed around a dead parasitic worm.
- This case represents a rare instance of biliary ascariasis associated with gallstone formation in Korea within the last five years.
Implications:
- This case underscores the importance of considering parasitic infections as a potential etiology for gallstone formation, even in endemic areas.
- It highlights the need for awareness among clinicians regarding biliary ascariasis as a cause of hepatobiliary symptoms.
- Further investigation into the prevalence and clinical significance of parasitic-induced cholelithiasis may be warranted.
