Percutaneous Transhepatic Cholangioscopy and Stone Extraction in a Patient with Recurrent Cholangitis Following Liver Trauma

Percutaneous transhepatic cholangioscopy (PTCS) is a safe and effective treatment for obstructive biliary stones, when endoscopic retrograde cholangiopancreatography (ERCP) is unsuccessful or unavailable. Once percutaneous access is gained into the biliary tree by an interventional radiologist, the biliary ducts can be directly visualized and any biliary stones can be managed with lithotripsy, mechanical fragmentation, and/or percutaneous extraction. We report a case of a 45-year-old man who sustained a traumatic liver laceration and associated bile duct injury, complicated by bile duct ectasia and intrahepatic biliary stone formation. Despite undergoing a cholecystectomy, multiple ERCPs, and percutaneous transhepatic cholangiogram with drain placement, the underlying problem was not corrected leading to recurrent bouts of gallstone pancreatitis and cholangitis. He was ultimately referred to an interventional radiologist who extracted the impacted intrahepatic biliary stones that were thought to be causing his recurrent infections through cholangioscopy. This is the first case of PTCS with biliary stone extraction in the setting of recurrent biliary obstruction and cholangitis due to traumatic bile duct injury.
