Nasobiliary Drainage (ENBD)

Endoscopic nasobiliary drainage (ENBD) is performed by duodenal endoscopy, which is placed in the appropriate part of the bile duct, and finally extracted from the nasal cavity of the patient to achieve bile drainage to the outside of the bile duct obstruction or lesion. Microscopic treatment. Hepatic hilar biliary tumors, intrahepatic multi-stage bile duct invasion and drainage are extremely limited, and should be used with caution. Basic Information Specialist Category: Otolaryngology Examination Category: Endoscope Applicable gender: whether men and women apply fasting: fasting Tips: Fast for 4-6 hours before check. Normal value Three minutes after the operation, the golden 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: no bile outflow. Need to check the crowd: 1, obstructive jaundice patients before surgery to reduce yellow drainage. 2. Emergency decompression drainage of severe cholangitis and severe pancreatitis. 3. Flushing and drainage of patients with bile duct stones. Precautions Contraindications before examination: fasting for 4 to 6 hours before examination.

Operation method: After inserting the duodenoscope into the descending part and finding the sphincter nipple, the endoscopic cholangiography is performed first. After the obstruction site is determined, the guide wire is inserted into the bile duct above the obstruction, and the bile duct with the widest drainage range is selected. An elongated polyethylene nasal bile duct with an outer diameter of 6~8Fr is inserted into the guide wire, and the guide wire is taken out after reaching the predetermined part. The nasal bile duct is first taken out from the mouth, and finally a nasal catheter is taken out from the nostril and properly fixed. At the cheek, a sterile drainage bag is attached.
