Poop pills could stop deadly bile duct infections
NCT ID NCT07509346
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether transplanting gut bacteria from healthy donors can prevent repeat episodes of a serious bile duct infection called cholangitis. About 44 adults who have had at least two infections in the past year will receive either fecal transplants or standard care. The goal is to see if this approach can reduce future infections, hospital stays, and the need for antibiotics.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria - Patients ≥18 years of age who have had ≥2 episodes of acute cholangitis in the past year. Exclusion criteria * Oral intolerance or inability to swallow capsules. * Pregnancy or breastfeeding. * Any clinically significant disease (other than RAC) such as disseminated malignancy or organ failure resulting in relevant cardiac, hepatic, pulmonary, or neurodegenerative disease with an expected survival of less than one year. Inability to understand the study, sign the informed consent, and/or collect stool samples. \- RAC due to the presence of choledocholithiasis (any number of stones in the biliary tract) or extrahepatic bile duct stricture that cannot be resolved by surgical or endoscopic treatment. Lack of resolution of extrahepatic biliary obstruction is defined as failure to remove all stones, or a residual diameter in stricture cases of less than 75% of the bile duct diameter above and below the stricture, even after balloon dilation and/or biliary stent placement
