Abstract: Various bile duct injuries caused bile lea kage or biliary obstruction and severe secondary longterm complications which threaten patients′ survival. At present, confir mative surgeries to reconstruct bile flow into gastrointestinal tract remains as a major resort to treat bile duct injury. Successful reconstruction mainly depends on experienced surgeons armed with precisely biliary surgical technology. Surgical repair should be based on cautious preoperative assessment and identification of bile duct injury. The basic principle of reconstruction includes that anastomosis is performed on the healthy bile duct with sufficient blood supply and without inflammation, ischemia and scar. The core of reconstruction includes the exposure of proximal and distal bile ducts and preparation of materials for repair and anastomosis. The definite goal of this surgery is to build up an unobstructed biliary drainage, tensionfree mucosa with sufficient blood supply for mucosa anastomosis.
