Fecal microbiota transplantation as a preventive treatment for recurrent acute cholangitis.

Background: Recurrent acute cholangitis (RAC) is a relatively uncommon entity that presents significant management difficulties. We present the case of a patient with RAC in whom the number of episodes was reduced after a novel therapeutic procedure. Case report: A 93-year-old male who in June 2019 was admitted for chills without fever, shivering, epigastric abdominal pain and moderate jaundice. Both abdominal ultrasound and CT scan showed intrahepatic and extrahepatic duct dilatation up to the papilla with no evidence of mass at that level. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and abundant biliary sludge was removed. E. coli was identified as the cause of several of the episodes. Some isolates were shown to produce extended spectrum beta-lactamase (ESBL). Papillotomy was performed and plastic prosthesis and later a metallic prosthesis were implanted. Several months later a surgical bypass of the biliary tract was performed due to persistent episodes of cholangitis. When the chronic suppressive antibiotic treatment subsequently instituted to prevent new episodes of cholangitis failed, it was decided to perform a fecal microbiota transplant from a healthy donor and to suspend the chronic suppressive treatment. Since then, she has not presented new episodes of RAC for more than 10 months of clinical follow-up. BLEE-producing E. coli in the gastrointestinal tract could not be eradicated. Comment: Chronic colonization of the biliary tract by certain enterobacteria such as E. coli has been identified as a relevant pathogenic factor in cases of RAC. FMT may be a promising tool to improve the clinical course of patients with RAC.
