Physiology Bile ducts Q Intrahepatic biliary tract Q Extrahepatic biliary tract Gallbladder Q Concentrates and stores hepatic bile during the fasting state and delivers bile into the duodenum in response to a meal o The gallbladder epithelial cell secretes at least two important products into the gallbladder lumen: glycoproteins and hydrogen ions Sphincter of oddi It creates a high-pressure zone between the bile duct and the duodenum o The sphincter regulates the flow of bile and pancreatic juice into the duodenum prevents the regurgitation of duodenal contents into the biliary tract
Physiology ➢Bile Ducts ◆ Intrahepatic biliary tract ◆ Extrahepatic biliary tract ➢Gallbladder ◆ Concentrates and stores hepatic bile during the fasting state and delivers bile into the duodenum in response to a meal ◆ The gallbladder epithelial cell secretes at least two important products into the gallbladder lumen: glycoproteins and hydrogen ions ➢Sphincter of Oddi ◆ It creates a high-pressure zone between the bile duct and the duodenum ◆ The sphincter regulates the flow of bile and pancreatic juice into the duodenum, prevents the regurgitation of duodenal contents into the biliary tract

➢An aggressive malignancy that occurs predominantly in elderly people. ➢Besides the exceptional cases detected incidentally at the time of cholecystectomy for gallstone disease, which are usually early stage, the prognosis for most patients is poor. ➢Reported 5-year survival rates:5% ~38%. Gallbladder Cancer
Gallbladder cancer >Incidence o Cancer of the gallbladder is two to three times more common in women than men, in part because of the higher incidence of gallstones in women More than 75% of patients with this malignancy are older than 65 years o The incidence of gallbladder cancer varies considerably with both ethnic background and geographic location
