Biliary Stent Drainage (ERBD)

Biliary stent drainage (ERBD)

Biliary stent drainage (ERBD) can effectively alleviate the condition of patients with malignant biliary obstruction. For patients with malignant biliary obstruction who cannot be radically resectable by surgery, endoscopic placement of biliary stents is the best preferred method, which has less trauma and fewer complications.

Basic information

Specialty category: Digestive Examination category: Endoscopy

Applicable gender: Both men and women. Whether fasting: Fasting

Warm reminder: Fast for 4 to 6 hours before the examination.

Normal values of biliary stent drainage (ERBD) :

After the operation, golden-yellow bile was observed to be drained out of the body, which quickly relieved biliary obstruction, reduced biliary pressure and ensured smooth drainage. As a result, the patient's condition was rapidly alleviated and the infection was controlled.

Clinical significance of biliary stent drainage (ERBD) :

Abnormal result: No bile outflow.

The population to be examined: 

(1) The elderly or those with high surgical risks and who are not suitable for surgery; Those who are not suitable for EST or have failed endoscopic stone removal; It can be used as a preoperative preparation to prevent stone impaction or the onset of cholangitis. 

(2) Benign biliary stricture. It can be used after endoscopic biliary dilation and also for the treatment of sclerosing cholangitis. 

(3) Biliary fistula.

Precautions for biliary stent drainage (ERBD) :

Not suitable for: Patients with hilar bile duct tumors and those with extremely limited drainage range due to invasion of multiple branch bile ducts within the liver should use with caution.

Pre-examination contraindications: Fast for 4 to 6 hours before the examination.

During the examination: If you feel unwell, inform the doctor in time and cooperate actively with the doctor's requirements.

The examination process of biliary stent drainage (ERBD) :

First, perform ERCP (retrograde cholangiopancreatography) to determine the location of the obstruction and the length of the stenosis. Under the guidance of a guide wire, use a biliary probing strip to dilate the stenosis. Select an appropriate internal drainage stent and place the distal end in the intestinal tract outside the duodenal papillae. At the same time, to ensure the patency of the internal stent, it must be replaced approximately every three months.

Unsuitable population for biliary stent drainage (ERBD) :

Not suitable for: Patients with hilar bile duct tumors and those with extremely limited drainage range due to invasion of multiple branch bile ducts within the liver should use with caution.
