RESUMEN
Objective To investigate the value of interventional therapy in bile duct injury (BDI) due to laparoscopie cholecystectomy (LC). Methods Data of 24 BDI patients, who received interventional treatment after LC from June 1997 to May 2007, were retrospectively analyzed. Results According to Liu Yunyi criteria of BDI classification, there were 5 cases of type Ⅰ , 11 cases type Ⅱ , 2 type Ⅲ and 6 type Ⅳ. BDI was found during LC in 2 patients and the operation was switched to open cholecysteetomy, but bile duct infection was experienced 10 months and 2 years after the operation, respectively. BDI was diagnosed postoperatively in 22 patients, in which 13 eases occurred 3-12 days after LC, 7 cases 20-60 days after LC, and 2 cases 2 years after LC. Complete remission was achieved by interventional therapy in 5 patients, the other 19 patients received curative operation after control of cholangitis and jaundice. Among 13 patients who were diagnosed BDI 3-12 days after LC, 6 underwent emergency operation and failed. Of the 7 other patients who received interventional therapy, 3 were cured and the others underwent curative operation after cholangi-tis and jaundice were controlled. Conclusion Application of interventional therapy in BDI after LC can a-chieve successful bile duct support and drainage, and can obtain complete image of bile duct system, which is effective not only in control of cholangitis and jaundice for the safety of the following surgery, but also in cure of BDI.
