Clonorchiasis

Last edited: 4/15/2026

Overview

Clonorchiasis is an infectious disease caused by the liver fluke Clonorchis sinensis, typically leading to chronic symptoms involving the biliary tract. It can also present acutely, manifesting with gastrointestinal disturbances, liver abscesses, or severe complications like esophageal varices in endemic regions or among immigrants 12.

Diagnosis

  • Clinical Presentation: Chronic gastrointestinal symptoms, cholangiocarcinoma, acute presentations with diarrhea and liver abscesses 1.
  • Imaging: Ultrasound or CT scan may reveal biliary abnormalities or liver abscesses 1.
  • Serological Tests: Antibody detection for Clonorchis sinensis 2.
  • Stool Examination: Ova detection for definitive diagnosis 2.
  • Endoscopic Findings: Esophageal varices in severe cases 2.
  • Management

  • First-Line Treatment:
  • - Antibiotics: Triclabendazole (10 mg/kg/day for 1 day) is recommended for eradication of the parasite 2.
  • Adjunctive Treatments:
  • - Symptomatic Care: Management of complications such as liver abscesses or esophageal varices 12. - Monitoring: Regular follow-up to assess for recurrence and complications 2.

    Special Populations

  • Pediatrics: Acute presentations can occur, requiring prompt diagnosis and treatment 1.
  • Immigrants: Increased vigilance for imported diseases; consider clonorchiasis in patients with relevant symptoms 2.
  • Key Recommendations

  • Consider clonorchiasis in the differential diagnosis for immigrants presenting with gastrointestinal symptoms or complications like esophageal varices (Evidence: Moderate 2).
  • Use triclabendazole as the first-line treatment for confirmed clonorchiasis cases (Evidence: Expert opinion 2).
  • Perform serological testing and stool examination for definitive diagnosis (Evidence: Moderate 2).
