Summary

This trial will help researchers understand if giving antibiotics to people before they undergo the ERCP procedure can help prevent cholangitis, a condition where the bile ducts become inflamed.

Who is the study for?
This trial is for adults aged 18 to 90 undergoing therapeutic ERCP for bile duct stones or obstructions, among other indications. Excluded are those with renal insufficiency, mandatory need for antibiotics, certain conditions like primary sclerosing cholangitis or neutropenia, active infections requiring antibiotics, recent ERCP within 30 days, pregnant women, incarcerated individuals and those allergic to the study drugs.
What is being tested?
The trial tests if prophylactic antibiotics (Ceftriaxone or Levofloxacin) can reduce post-ERCP cholangitis rates. It's designed to settle debates on antibiotic use in standard-risk ERCP procedures by comparing outcomes with and without these preventive medications.
What are the potential side effects?
Possible side effects of Ceftriaxone and Levofloxacin may include allergic reactions, gastrointestinal issues like nausea or diarrhea, headache, dizziness and potential risk of tendon damage or inflammation.
