Overview
Antimicrobial therapy is indicated for acute cholangitis. Patients with community- acquired mild to moderate disease are treated with Cephalosporins. All other patients are treated with a combination of Metronidazole and either Imipenem-Cilastatin, Meropenem, Doripenem, Piperacillin-Tazobactam, Ciprofloxacin, Levofloxacin, or Cefepime.
Medical Therapy
- Approximately 80% of patients with acute cholangitis will respond to conservative therapy and elective drainage.
- In 15-20%, the cholangitis will progress requiring emergent drainage. Markers for these people are persistent abdominal pain, hypotensive, fever >102, and confusion.
- Patients should be kept NPO, given intravenous fluids, broad spectrum antibiotics, Vitamin K and be drained.
- Choices for drainage are ERCP with stone removal and sphincterotomy/stent placement, surgical drainage or percutaneous drainage.
- Intrahepatic stones cannot be removed via ERCP and should be drained percutaneously.
- Randomized trials comparing ERCP and surgery showed morbidity and mortality benefit for ERCP (4.7-10% versus 10-50%).
- A nasobiliary catheter can be placed if ERCP is impossible (<5%), either because of coagulopathy, precluding sphincterotomy, or too large a stone (>2cm) etc. Next step should be percutaneous drainage as a bridge to elective surgery since emergent surgery may have up to 40% mortality.
