Summary
Urgent endoscopic biliary drainage is highly effective for acute calculous cholangitis unresponsive to conservative care. Prompt drainage, especially before 72 hours in shock patients, significantly improves survival rates.
Area of Science:
- Gastroenterology
- Hepatology
- Surgical Endoscopy
Background:
- Acute calculous cholangitis is a serious biliary infection often requiring intervention.
- Conservative management alone may be insufficient for severe cases.
- Prompt biliary decompression is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and safety of urgent endoscopic biliary drainage.
- To assess the impact of drainage timing on mortality in patients with acute calculous cholangitis.
- To identify factors influencing outcomes in this patient population.
Main Methods:
- Retrospective analysis of 105 patients with acute calculous cholangitis.
- Urgent endoscopic biliary drainage performed for non-responders to conservative management.
- Analysis of treatment success, mortality, and timing of drainage relative to shock status.
Main Results:
- Endoscopic drainage achieved a 97% success rate.
- Overall mortality was 4.7%.
- In patients with shock, drainage after 72 hours had a higher mortality (2/4) compared to drainage before 72 hours (3/38); no deaths occurred in non-shock patients regardless of drainage timing.
Conclusions:
- Urgent endoscopic biliary drainage is a safe and effective treatment for acute calculous cholangitis.
- Timely drainage, particularly within 72 hours for patients in shock, is associated with improved survival.
- Early intervention is critical for reducing mortality in severe cholangitis.
