Background
When the bile duct is blocked due to reasons such as calculus obstruction, scar stenosis and tumor, a surgeon usually connects the bile duct near the blocked part with the intestine directly, so that the bile can directly flow into the intestine through the interface, and the operation becomes choleintestinal anastomosis just like opening another passage in the road after one end of the road is blocked and blocked. The specific methods of choleenteroanastomosis are various, and the most commonly performed choledochoduodenostomy, choledochoduodenostomy and addison's enlarged myotomy are choledochostomy at ordinary times. The common bile duct jejunostomy is to perform Y-shaped anastomosis on the common bile duct and the jejunum, the operation is complex and time-consuming, but the operation causes a longer section of jejunum under the common bile duct to be specially used for conveying bile, and chyme flows back to the common bile duct and needs to pass through a longer distance, so the chance of causing biliary tract infection is smaller, and the operation has the greatest advantage. Common bile duct jejunostomy is mainly suitable for patients with common bile duct stenosis (traumatic or inflammatory) and patients with intrahepatic bile duct stones. Patients whose cancer at the lower end of the common bile duct cannot be removed by surgery may sometimes have such a surgery.
The incidence of the narrow anastomotic stoma of the biliary and intestinal tracts is high, the common treatment method comprises the steps of puncturing the percutaneous intrahepatic bile duct, performing sacculus expansion at the narrow anastomotic stoma, placing the drainage tube inside and outside the biliary tract, needing repeated expansion, replacing the drainage tube which is gradually thickened, and the restenosis possibly occurs after several months or years after the sacculus expansion treatment, so that the large economic burden and the body pain are brought to the patient, and the drainage tube which can be repeatedly expanded and is placed once is clinically needed.
