Iatrogenic biliary tract complications: radiologic features and clinical significance

Thirteen intrahepatic and 22 extrahepatic biliary tract complications were detected radiologically in 35 adult patients who had undergone cholecystectomy and bile duct exploration. Intraoperative usage of Fogarty balloon catheters to extract biliary calculi without fluoroscopic guidance resulted in focal ectasia or rupture of intrahepatic radicles in two and seven cases, respectively. Metallic surgical instruments such as Bakes dilators and biliary forceps or clamps accounted for most of the common duct injuries; these were manifested as submucosal dissection (two cases), transmural laceration (four cases), or localized trauma with subsequent stricture (three cases). Technical mishaps during T-tube placement led to common duct perforation (four cases) and extraluminal malposition of T tubes (three cases). The remaining complications included choledochoduodenal fistula (three cases), biliovenous fistula (two cases), biloma (three cases), and retained intraductal fragments of biliary drainage catheters (two cases). Knowledge about radiologic features and causal factors of such iatrogenic processes can play a crucial role in their prevention, correct diagnosis, and management.
