The gall bladder is a hollow organ that serves as a reservoir for bile. The gallbladder is a thin pear-shaped bag with a capacity of 40 - 70 ml of bile. It is adjacent to the lower surface of the liver (Fig. 1); the bottom it is facing toward the front, the neck - back, at the angle passing into the cystic duct. The gallbladder is supplied by the blood of two branches artery gallbladder, running along the top and bottom surfaces. Vienna him fall into the veins of the liver and the right branch of the portal vein. The lymphatic vessels of the gallbladder to join in the lymph nodes of the neck of the gallbladder and the gate of the liver. They are innervated by the gallbladder and bile ducts wandering, celiac and right phrenic nerves.
The bile ducts - biliary pathways through which bile comes from the liver to the intestine. Both the left and right lobes goes right and left hepatic ducts, uniting in common hepatic duct; the latter is connected with the cystic duct to form the common bile duct. The common bile duct empties into the duodenum together with duct pancreas.
The mucous membrane of the biliary tract and gall bladder covered cylindrical epithelium and forms folds. In the cystic duct mucous membrane forms a spiral valve. The muscular layer of the bladder at the junction of the cervix in cystic duct increases and creates a sort of cervical sphincter. Another muscle pulp is located at the confluence of the common bile duct into the duodenum - sphincter-liver-pancreas ampoule (the sphincter of Oddi).
Research methods of the gallbladder and bile ducts. During the examination of right rib unchanged the gall bladder is not palpated. Is palpated gallbladder when the obstruction of the common bile duct is a sign Courvoisier - Terre. The research function of the gallbladder is performed by means of intelligent sensors - see Duodenal intubation.
X-ray examination of the gallbladder and bile duct see Cholangiography, Holografia, Cholecystography. Cm. also Radioisotope diagnostics.
