Endoscopic bile duct metal stent drainage

EMBE is only suitable for patients with malignant biliary obstruction who cannot be radically resected. It is best to have a drainage drainage biliary system that is ideal for estimating drainage and has no other important organ dysfunction and is expected to survive at least 3 months. Treatment of diseases: acute obstructive suppurative cholangitis Indication EMBE is only suitable for patients with malignant biliary obstruction who cannot be radically resected. It is best to have a drainage drainage biliary system that is ideal for estimating drainage and has no other important organ dysfunction and is expected to survive at least 3 months. Contraindications ERCP contraindications, benign biliary diseases. Preoperative preparation 1. The instrument preparation is the same as ERBD. In addition, various specifications of metal biliary stents are prepared. Read the product manual carefully before operation to understand the performance characteristics of the stent, preparation and release methods before operation, and prepare according to the requirements. 2. The patient is prepared to drain with the nasal bile duct. Surgical procedure 1. First, biliary catheterization, to understand the nature, location, and extent of the lesion, and determine the length of the metal stent. 2. Feed the guide wire through the narrow section and select the bile duct to be drained. 3. The guidewire is inserted into the dilator to expand the stenosis. 4. The stent-equipped conveyor is fed into the biliary tract to reach the obstruction site, and finally the stent is slowly released under continuous fluoroscopy and endoscopic control. complication 1. Cholangitis and sepsis are mainly seen in patients with inadequate drainage, or intraoperative injection of excessive contrast agent in the biliary tract, excessive biliary pressure, and generally effective anti-inflammatory treatment. 2. Pancreatitis is generally mild, in addition to fasting, appropriate amount of anti-pancreatic enzyme or drugs that inhibit pancreatic secretion. 3. The cause of stent occlusion failure is mainly caused by tumor growth in the mesh of the stent or growth of the stent at both ends of the stent. A metal or plastic stent can be placed in the center of the stent, or the nasal bile duct can be drained, and the biliary obstruction can still be effectively relieved. .
