Preoperative Preparation For Biliary Tract Disease

Due to cholestasis, patients with biliary calculi or tumors may have poor liver function, jaundice, low plasma protein, poor coagulation and immune function, even cholangitis, pancreatitis and other manifestations, which may delay the time of surgery and affect the outcome of surgery.

PTCD and other preoperative bile drainage methods can relieve cholestasis, improve liver function, regulate coagulation and immune function, and reduce the time of preoperative preparation.

The fibrous sinus tract formed by PTCD tube can be treated by percutaneous transhepatic choledochoscopy (PTCS) for patients with inoperable intrahepatic and intrahepatic bile duct calculi. It usually takes 4 to 6 weeks to form mature fibrous sinus tract after catheterization.
