Abstract:
Biliary obstructions can lead to infections of the biliary system, particularly in patients with occluded biliary stents. Fungal organisms are frequently found in biliary aspirates of patients who have been on antibiotics and have stents; however, fungal masses, or "balls", that fully obstruct the biliary system are uncommon and exceedingly difficult to eradicate. We present 4 cases of obstructing fungal cholangitis in patients who had metal biliary stents placed for pancreatic malignancies, and subsequently required aggressive antifungal administration along with endoscopic and radiologic interventions. This report also reviews approaches previously undertaken to manage severe obstructing fungal cholangitis.
Insights
Obstructing fungal cholangitis, a rare complication of biliary stents, requires aggressive antifungal treatment and interventions. This study details four challenging cases and reviews management strategies for this difficult-to-eradicate condition.
Area of Science:
- Gastroenterology and Hepatology
- Infectious Diseases
Background:
- Biliary obstructions, often managed with stents, can lead to biliary system infections.
- Fungal organisms are common in biliary aspirates of patients with stents and antibiotic use.
- Fully obstructing fungal masses in the biliary system are rare and challenging to treat.
Observation:
- This report details four cases of obstructing fungal cholangitis in patients with metal biliary stents for pancreatic malignancies.
- These patients required intensive antifungal therapy combined with endoscopic and radiologic interventions.
Findings:
- Aggressive antifungal administration and multidisciplinary interventions are crucial for managing obstructing fungal cholangitis.
- Successful eradication of fungal balls causing biliary obstruction necessitates a combination of medical and procedural approaches.
Implications:
- This case series highlights the complexity of treating fungal biliary obstruction in patients with pancreatic cancer.
- Understanding effective management strategies is vital for improving outcomes in these critically ill patients.
- Further research into novel therapeutic approaches for fungal cholangitis is warranted.
