Cholecystitis alone does not usually cause pancreatitis; it is when a person with cholecystitis combines it with gallbladder stones or cholangitis that pancreatitis may occur. Bile and pancreatic juices travel down the common bile duct and pancreatic duct before emptying into the duodenum, passing through a common channel formed by the confluence of the pancreatic and common bile ducts. In patients with gallbladder stones and cholecystitis, the stones will move along with the bile down the common bile duct, blocking the end of the pancreatic duct and preventing the pancreatic juices from being discharged or entering the pancreas through the pancreatic duct, leading to digestion in the pancreas itself and causing cholestatic pancreatitis. Cholecystitis can cause pancreatitis, so cholecystitis patients timely medical treatment, standardized treatment under the guidance of the physician, further improve the examination to clarify the presence of gallbladder and bile duct stones, biliary tract infection, etc., and actively early treatment, so as to avoid triggering acute cholangiogenic pancreatitis.
