Acute biliary pancreatitis accounts for more than half of the annual incidence of pancreatitis in China. The pathogenesis is generally believed to be due to inflammation, edema, obstruction and stenosis of the sphincter of Oddi in the jugular abdomen of the duodenum caused by stones, roundworms, tumors and diverticula in the common bile duct, which causes bile to flow back into the pancreas, or due to biliary tract infection and inflammatory exudate spreading to the pancreas through the traffic branches of the biliopancreatic interstitial lymphatics. Congenital anomalies of pancreaticobiliary merging, especially common bile duct converging into pancreatic duct type (CP type) APBDU is considered to be an important factor in the occurrence of ABP. In the past hundred years, with the gradual improvement in the understanding of the pathogenesis and pathophysiology of acute pancreatitis, the current treatment mode of acute pancreatitis, especially the early onset of severe acute pancreatitis, is usually based on conservative treatment such as fluid resuscitation and organ function support. However, as a special type of acute pancreatitis, ABP, especially when complete biliary obstruction is complicated by acute cholangitis, must be treated with emergency biliary decompression and drainage in order to relieve the condition. In recent years, the development of endoscopic interventional techniques has provided a new and effective means of diagnosis and treatment for ABP, and it has been more and more widely used in clinical practice. It can be seen that biliary pancreatitis involves many diseases such as cholecystitis, gallbladder stones, common bile duct stones, intra- and extra-hepatic bile duct stones, congenital cystic dilatation of the common bile duct, bile duct cysts, and pancreatic cysts. All of them require in-depth understanding for better diagnosis and treatment. Treatment involves endoscopy, duodenoscopy, ultrasound endoscopy, laparoscopy, imaging, clinical nutrition therapy, rapid rehabilitation surgery theory and other multidisciplinary and multitechnical support in order to obtain immediate treatment results. Pancreatitis is divided into 3 phases: 1-2 weeks is the period of systemic inflammatory response: this phase requires fluid resuscitation, nutritional support (requires the foundation of clinical nutritionist, ignored by surgeons, I like this discipline) to stabilize circulation. Interspersed acute biliary obstruction requires prompt biliary drainage. This time, the patient’s condition was severe, duodenoscopic treatment was preferred, and open surgery was traumatic and aggravated pancreatitis. Our center has endoscopic techniques, which I master. The most important thing in this period is the principle of TCM treatment as Tongli attack: apply laxative herbs to make the stool expel as soon as possible (pancreatitis patients are bloated and do not defecate), reduce abdominal pressure, relieve pain and prevent intestinal bacteria from migrating around the pancreas and causing infection. (Purely Western doctors do not have the knowledge of TCM theory, I am proficient in TCM theory and use the combination of Chinese herbal medicine prescription and Western medicine single product to promote the patient’s intestinal flux, the advantages complement each other and the effect is good) After 2 weeks – 1 month into the infection period: Most of them are patients who are not improved after treatment in other hospitals and are transferred to our department. The common feature is that they missed the effective treatment in the first stage, which led to intestinal inaccessibility and bacterial translocation to turn the aseptic pancreatitis in the first stage into bacterial infectious pancreatitis, peripancreatic suppuration and high fever of infection. He was referred to me for endoscopic and gastroscopic administration of enteral nutrition tube, and was given enteral and parenteral nutrition treatment, and after intestinal passage, enteral nutrition (economical) was the mainstay to maintain positive nitrogen balance and prepare for cleanup surgery. CT is detected to place a drainage tube and flush against the mouth. Currently, most of the options are puncture and drainage under color ultrasound because of the economy and savings to the patient. Choledochoscopy may be applied. When an abscess is formed, laparoscopic removal of the abscess and abdominal drainage are performed. The recovery period can be entered after 1-3 procedures. In the second stage, the evil is strong and the positive is weak, so Chinese medicine should support the positive and dispel the evil, and reuse raw astragalus to support the poison to go out. Recovery period: This period is prone to complications such as biliary fistula and intestinal fistula. I can solve it with the help of endoscopic technology, no need to open surgery. Chinese medicine for the late stage of febrile disease, both qi and fluid, should be given orally with bamboo leaf and gypsum soup to benefit qi and nourish yin. To promote recovery. Pseudocysts of the pancreas may remain in the later stage. I have individualized the treatment of pancreatic pseudocysts, a distant complication of pancreatitis.
