Background
The current management of acute cholangitis consists of antibiotic therapy in combination with biliary drainage. However, the optimal duration of antibiotic therapy after the resolution of clinical symptoms by biliary drainage is unclear. We aimed to evaluate whether discontinuing antibiotic therapy for acute cholangitis immediately after the resolution of clinical symptoms, achieved by endoscopic biliary drainage, was safe and effective.
Methods
This prospective study included patients with moderate and severe acute cholangitis. Cefmetazole sodium and meropenem hydrate were used as initial antibiotic therapy for patients with moderate and severe acute cholangitis, respectively. All patients underwent endoscopic biliary drainage within 24 h of diagnosis. When the body temperature of <37°C was maintained for 24 h, administration of antibiotics was stopped. The primary endpoint was the recurrence of acute cholangitis within 3 days after the withdrawal of antibiotic therapy.
Results
Eighteen patients were subjected to the final analysis. The causes of cholangitis were bile duct stone (n = 17) and bile duct cancer (n = 1). The severity of acute cholangitis was moderate in 14 patients and severe in 4. Body temperature of <37°C was achieved in all patients after a median of 2 days (range 1–6) following endoscopic biliary drainage. Antibiotic therapy was administered for a median duration of 3 days (range 2–7). None of the patients developed recurrent cholangitis within 3 days after the withdrawal of antibiotics.
Conclusions
Fever-based antibiotic therapy for acute cholangitis is safe and effective when resolution of fever is achieved following endoscopic biliary drainage.
