[Repair of the large hepatobiliary duct defect with pedicle flap graft of the gallbladder or jejunum].

Sixteen patients suffering from complicated hepatolithiasis and ductal stricture were treated with a special U-shaped double balloon drainage catheter designed by the authors, and pedicle flap graft of gallbladder or jejunum for repair of large hepatobiliary duct defect were introduced. The follow-up study for 9-25 months (average 13.6 months) showed that the short-term results were excellent in all cases. The material structure of the drainage, the clinical diagnostic criteria of the disorder, the procedure of the operation and the clinical observation were also discussed.
