Biliary stent drainage (ERBD) can effectively alleviate the condition of patients with malignant biliary obstruction. For patients with malignant biliary obstruction who cannot undergo radical resection, endoscopic placement of biliary stent is the best choice. It has less trauma and less complications. . Hepatic hilar biliary tumors, intrahepatic multi-stage bile duct invasion and drainage are extremely limited, and should be used with caution.

Basic Information

Specialist classification: Digestive examination classification: endoscope

Applicable gender: whether men and women apply fasting: fasting

Tips: Fast for 4-6 hours before check. Normal value

After the operation, golden brown bile was taken out of the body, and the biliary obstruction was quickly relieved, the biliary pressure was lowered, and the drainage was smoothed, so that the patient's condition was quickly relieved and the infection was controlled.

Clinical significance

Abnormal results did not flow out of bile.

Need to check the crowd: (1) elderly or other surgery risk, should not be operated; not suitable for EST or endoscopic stone removal; prevention of stone incarceration or cholangitis, can be used as preoperative preparation; (2) benign biliary stricture. Can be used after endoscopic biliary dilatation, can also treat sclerosing cholangitis; (3) biliary fistula.

Precautions

Contraindications before examination: fasting for 4 to 6 hours before examination.

At the time of examination: If you have any discomfort, you should tell the doctor promptly and actively cooperate with the doctor's request.

Inspection process

First ERCP [retrograde cholangiopancreatography], to understand the location of the obstruction and the length of the stenosis, use the biliary tract to expand the stenosis under the guidance of the guide wire, select the appropriate internal drainage stent, and place the distal end in the duodenum In the outer ileum of the nipple, at the same time, in order to ensure the smoothness of the inner stent, it must be replaced in about three months.

Not suitable for the crowd

Unsuitable for the population: the hilar cholangiocarcinoma, the intrahepatic multi-stage bile duct invasion and drainage range is extremely limited, and should be used with caution.

Adverse reactions and risks

Nothing.
