The Conservative Management of Choledocholithiasis With Ursodeoxycholic Acid

Choledocholithiasis has been defined as the presence of stones within the common bile duct (CBD) with up to one-half of the cases remaining asymptomatic. We report a case of an 84-year-old frail male admitted for the treatment of pneumonia, pleural effusion, and bacteraemia with co-incidental deranged liver function tests (LFTs). Ensuing magnetic resonance cholangiopancreatography (MRCP) noted three CBD stones; however, the patient remained asymptomatic. After discussing the benefits and risks of treatment options with the gastroenterology team, the patient refused endoscopic retrograde cholangiopancreatography (ERCP) and opted for close monitoring in the community whilst taking ursodeoxycholic acid (UDCA). In the months following, his LFTs normalised, and repeat MRCP no longer showed stones. This case demonstrates that UDCA with close monitoring may be considered a non-invasive alternative treatment of CBD stones, particularly in elderly or frail patients with multiple comorbidities.
