Dr. Hung KaWai Ray Team 1 Hepatobiliary and Pancreatic Surgery Prince of Wales Hospital Classification and management of bile duct injury
Laparoscopic cholecystectomy • Standard treatment of symptomatic gallstone disease • > 750, 000 were performed annually in the United States • Less pain, fewer wound complication, quicker recovery • The only potential disadvantage is a higher incidence of major bile duct injury [1], 0.3% open vs 0.6% laparoscopic Introduction
Bile duct injury is a very serious complication that lead to mortality, significant morbidity and impaired quality of life • Causes: • Iatrogenic • Cholecysectomy (80-85%) [2] • Gastrectomy • Pancreatectomy • ERCP • Trauma • Duodenal ulcer Introduction
Intraoperative • Direct observation of a divided duct • Bile in the operative field • Abnormal intra-operative cholangiography • Postoperative • Bile leak • Bile in the drain • Biloma, biliary fistula, or bile ascites • Bile peritonitis in severe cases • Biliary obstruction • Obstructive jaundice • Cholangitis Presentation
Bismuth • Strasberg et al. • Stewart et al. • McMahon et al. • AMA • Neuhaus et al. • Csendes et al. • Hanover • Lau and Lai • Siewert et al. • Cannon et al. • Kapoor Sandha et al. • EAES Classification
Depend on the timing of recognition of the injury • Intraoperative vs postoperative recognition Management
Account for 25%–32.4% [3] • First consult an experienced hepatobiliary surgeon • Convert to laparotomy with cholangiography • Define the nature of the injury • If expertise a/v • Immediate repair can minimize the morbidity • Higher successful rate, fewer morbidty and mortality [4] • If expertise not a/v • Injudicious attempts at exploration may cause further biliary and vascular injury • Subhepatic drain to prevent collection • External biliary drainage • Refer to a specialized hepatobiliary unit Intraoperative recognition
Aim of management • Control sepsis and limit inflammation • Delineate the biliary anatomy and associated vascular injury • Re-establish the biliary enteric continuity Postoperative recognition
Fluid resuscitation • Broad spectrum antibiotic • Investigation • USG / CT to asses collection +/- drainage Control sepsis
Cholangiography • ERCP • PTC • MRCP Delineate the biliary anatomy
CTA / MRA • Incidence is around 16.7%-47%[6] • Most commonly involving the right hepatic artery • Does not usually lead to early significant complications • Impact on bile duct injury [7] • Associated with increased intraoperative bleeding during repair • Difficult reconstruction • Higher incidence of anastomotic stricture due to bile duct ischamemia • Delayed repair if VBI is present Associated vascular injury
According to the type of injury Surgery vs endoscopic treatment Re-establish the biliary enteric continuity
Stricture • Balloon dilatation and biliary stenting • Hepaticojejunostomy has higher successful rate • Secondary biliary cirrhosis • Liver transplantation Treatment of Complication
