Background
Acute cholecystitis is a common disease and frequently encountered disease in China, and cholelithiasis is a main cause of cholelithiasis. The abdominal cholecystectomy is the traditional treatment scheme for acute cholecystitis, and the laparoscopic cholecystectomy becomes the main scheme for gallstones accompanied with the acute cholecystitis along with the development of endoscopic equipment and minimally invasive technology. With the rapid development of the 21 st century Chinese economic society, the aging of population gradually becomes one of the hot problems of the contemporary Chinese society, and the elderly patients often have basic diseases such as hypertension, diabetes, coronary heart disease and the like, and have poor tolerance to general anesthesia operation and long-time operation, on the basis, local anesthesia cholecystostomy, percutaneous transhepatobiliary puncture drainage (PTCD), endoscopic rhino-cholecystectomy (ENGD) and endoscopic retrograde cholecystectomy (ERGD) are derived, wherein the ENGD and the ERGD have small trauma, obvious curative effect and quick recovery, and are more suitable for the patients with ascites, hepatocirrhosis and acute cholecystitis. Compared with ENGD, ERGD travelling comfort is stronger, can not lead to the loss of bile, is more suitable for carrying out gall bladder and bile duct bile drainage person for a long time.
The ERGD is a conventional technology in the operation of the ERCP, not only can be applied to the treatment of acute cholecystitis, but also can be directly applied to the treatment of obstructive jaundice, acute suppurative cholangitis, biliary leakage and other diseases; the postoperative indwelling gallbladder internal drainage tube can fully drain bile of a gallbladder and a bile duct, reduce the pressure of the gallbladder and the bile duct, and reduce the probability of postoperative cholecystitis, pancreatitis and cholangitis.
At present, no commercialized gallbladder internal drainage tube is applied to clinic, and the gallbladder bile drainage is carried out by adopting a bile duct internal drainage tube clinically, the commonly used biliary tract internal drainage tube comprises a linear type, a single-pigtail type and a double-pigtail type, wherein the single-pigtail type bile duct internal drainage tube is most commonly used, and the bile duct internal drainage tube is applied to carry out the gallbladder bile drainage, so that the following problems exist: 1. the two ends of the drainage tube are provided with side holes, the tube body has no side holes, and after the head end of the drainage tube is placed in a gall bladder, the biliary tract internal drainage tube has no drainage effect on bile of a hepatobiliary duct, so that the effect of the biliary duct internal drainage tube is lost; 2. the intrahepatic bile can not enter the gallbladder through the cystic duct or the drainage tube, and the intrahepatic bile can not dilute inflammatory media in the gallbladder, which is not beneficial to the recovery of cholecystitis; 2. the cystic duct is arc-shaped and meets the common hepatic duct at an acute angle, the duct body of the biliary tract internal drainage tube is linear and is not matched with the physiological result of the biliary tract, the cystic duct is easy to be pressed after the biliary tract internal drainage tube is placed into the gall bladder, and the cystic wall is also easy to be pulled, so that the abdominal pain symptom is induced or the drainage tube is shifted; 3. the head end of the linear or single-pig tail biliary tract internal drainage tube is linear, and the head end easily presses the gallbladder mucosa, so that local hyperplasia and even gallbladder perforation are caused; 4. the end of the linear type and single-pig tail biliary tract internal drainage tube is provided with an agnail to prevent the drainage tube from shifting, the agnail is found to be easy to close by itself in clinic, and the morphological structure of the agnail is not matched with the biliary tract structure, so that the biliary tract internal drainage tube is easy to take off the biliary main tube through the gall bladder, and then the drainage effect on the gall bladder gall is lost.
