Abstract:
Carbohydrate antigen 19-9 (CA19-9) has been used as a tumor marker in the diagnosis and differentiation of pancreatic cancers. However, significantly high levels of CA 19-9 in the absence of pancreatic malignancy have also been reported. We present a 50-year-old woman with a common bile duct stone and cholangitis, whose CA 19-9 level of 1.500 U/ml returned to normal after definitive treatment of choledocholithiasis.

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
