Biliary dyskinesia is a digestive disorder in which bile physically can not move through the digestive tract normally. It involves abnormal tonus of the sphincter of Oddi (usually increased pressure), disturbance in the coordination of contraction of the biliary ducts, and/or reduction in the speed of emptying of the biliary tree. The gallbladder stores the bile which is released by the liver. The bile reaches the small intestine where it digests the fat from aliments. In order to reach the small intestine, the bile must pass through the common bile duct and when the bile can not be secreted by the gallbladder or can not flow through the common bile duct, then it will return to the gallbladder, leading to biliary dyskinesia. Biliary dyskinesia is often a disease symptom rather than a disease itself. It might signal the existence of gallbladder stones, acute or chronic pancreatitis, chronic inflammation, or other digestive disorders. However, symptoms can be induced by the consumption of certain types of food. Failure of the biliary sphincter can be distinguished from failure of the pancreatic sphincter. ==Treatment== Laparoscopic cholecystectomy has been used to treat the condition. Symptoms may persist after cholecystectomy, and have been linked to the use of proton pump inhibitors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Biliary dyskinesia」の詳細全文を読む スポンサード リンク
