The dangers of bile duct drainage

Biliary drainage is a common treatment method. It has a good therapeutic effect on bile duct obstruction and can clear the obstruction caused by bile stasis. Of course, during bile duct drainage, if the treatment is improper or the patient does not recover well, it may cause some hazards, such as bile duct infection, bile duct bleeding, or bile fistula. Therefore, when undergoing this treatment, you must go to a professional hospital and do a good preliminary examination.

The dangers of bile duct drainage

1. Biliary fistula; 2. Biliary tract infection; 3. Biliary tract bleeding.

Surgical steps 1. Left intrahepatic bile duct drainage surgical steps: ① Cut the round ligament and falciform ligament of the liver. ② Expose the left intrahepatic bile duct. ③Explore the intrahepatic bile duct. ④Suture. 2. The general steps of simple U-shaped tube hepatobiliary drainage are as follows: high incision of the common bile duct, gradual dilation of the hepatobiliary stenosis under direct vision, and insertion of a U-shaped tube.

3. Hepatobiliary jejunal anastomosis and U-shaped tube support drainage. The general steps of the operation: Although the hepatobiliary stenosis is incised, the hepatic duct above the stenosis is not obviously dilated or the stenosis is not fully incised, or the wall of the hepatobiliary duct is thick. Although the hepatobiliary jejunal anastomosis is performed, it cannot ensure that the anastomosis and the hepatobiliary will not be strictured after the operation. For such cases, U-shaped tube support drainage should be placed at the same time to maintain the patency of the hepatobiliary jejunal Roux-en-Y anastomosis, which has a good effect on maintaining the patency of the hepatobiliary jejunal Roux-en-Y anastomosis. 4. The general steps of bilateral hepatobiliary duct anastomosis and double U-shaped tube support drainage surgery: For patients with bilateral hepatobiliary duct stenosis, thick bile duct wall and portal hypertension caused by biliary cirrhosis, appropriate dilation of bilateral hepatobiliary duct stenosis, placement of U-shaped tube support drainage in both hepatic ducts, or opening of bilateral hepatobiliary duct stenosis as much as possible, performing Roux-en-Y anastomosis of hepatobiliary duct jejunal mucosal flap and placing double U-shaped tube support drainage.

Postoperative care 1. Keep the U-tube open and reduce bile sediment. 2. Dilatation of hepatobiliary stenosis with balloon U-shaped tube: 2 to 3 weeks after surgery, 25% meglumine is injected into the U-shaped tube, the balloon catheter is inflated, and the balloon is corrected and fixed in the same position as the hepatobiliary stenosis under television monitoring. Slowly inflate the hepatobiliary strictures once or twice a week. 3. Replace the U-tube regularly and replace it with a thicker one if necessary based on the results of cholangiography. 4. The U-tube or U-tube with balloon is placed for 1 year or longer.
