Cholestatic pancreatitis is easy to recur when treated, and the recurrence rate will be greatly reduced when treatment should be carried out according to the cause of pancreatitis. For pancreatitis caused by stones, gallbladder stones, common bile duct stones and intrahepatic bile duct stones, the recurrence rate of pancreatitis will be greatly reduced after the patient has removed the stones. The recurrence rate of pancreatitis caused by stone pancreatitis or non-stone pancreatitis, or pancreatitis caused by biliopancreatic confluence disease, is relatively higher, that is, after removing the stones from the common bile duct and gallbladder, or removing the gallbladder, or removing all the stones from the common bile duct and intra- and extra-hepatic bile duct, the recurrence rate of patients is relatively higher, because the cause of pancreatitis is not really solved. Biliopancreatic confluence problems include constrictive papillitis, sclerosing papillitis, overgrown papilla, parapapapillary diverticulum and other diseases, as well as pancreatitis caused by low and high biliopancreatic confluence abnormalities, which should be treated with ERCP minimally invasive technology, i.e. duodenoscopic minimally invasive technology, to open the pancreatic outflow tract and the bile duct outflow tract, and overgrown papilla can be dissected to shorten the outflow tract and biliopancreatic shunt. After effective treatment of pancreatitis for the cause, the recurrence rate will be greatly reduced or even not recurred.
