Ascariasis, a common worldwide helminthic infection, is endemic in areas with poor sanitation. This case highlights biliary ascariasis as an unusual cause of obstructive jaundice.
Area of Science:
- Parasitology
- Hepatology
- Gastroenterology
Background:
- Ascariasis, caused by Ascaris lumbricoides, is the most prevalent helminthic infection globally.
- It is endemic in regions with inadequate sanitation and low educational standards.
- Biliary ascariasis, a rare complication, can lead to obstructive jaundice.
Observation:
- A young laborer presented with acute abdominal pain.
- The patient's symptoms were indicative of biliary obstruction.
Findings:
- The diagnosis of biliary ascariasis was confirmed.
- Ascaris lumbricoides was identified as the causative agent of the obstructive jaundice.
Implications:
- This case underscores the importance of considering parasitic infections in the differential diagnosis of obstructive jaundice.
- Public health initiatives focusing on sanitation and education are crucial for controlling ascariasis.
- Awareness among clinicians regarding uncommon presentations of ascariasis is vital for timely diagnosis and treatment.
