It is connected to the liver (which produces the bile) by the hepatic duct.

This condition should be corrected by surgery before the liver is damaged or problems with infection ensue. When a gallstone travels through or obstructs a bile duct it can cause colic" >biliary colic, with severe pain. The pain is located in the upper right quadrant of the abdomen and radiates as far as the scapula. morphine is usually not given to relieve the pain because it increases spasm of the biliary sphincters. meperidine, which does not have this side effect, is the preferred medication for pain. Treatment may also include insertion of a nasogastric tube for the purpose of gastric suction to relieve distention in the upper gastrointestinal tract. ursodiol is a drug that can dissolve gallstones and reduce the need for surgery. Laparoscopic surgery is the usual method of treatment and is performed as soon as the patient is able to withstand it. In most cases the gallbladder is removed and a tube is inserted to establish drainage of bile that has been dammed up by the stone. (See also discussion of surgery at gallbladder.) For those patients unable to withstand cholecystectomy (gallbladder removal) but who still require drainage, cholecystostomy is indicated. ![]() gall·stone(gawl'stōn),gallstone(gôl′stōn′)gallstoneGastroenterology A concrement in the gallbladder or the cystic duct Epidemiology 10% of adults have gallstones–GS; ↑ with age; ♀:♂ = 2:1; highest in Scandinavia, Chile, Native Americans; ↑ risk with childbearing, ERT, OCs, obesity, rapid weight loss Types Cholesterol, bilirubin, calcium salts; cholesterol GSs constitute 75% of total in Western nations; up to 80% of the volume is cholesterol; non-cholesterol GSs are either black or brown GSs Clinical Biliary colic, recurrent upper-quadrant pain; fatty food intolerance, while suggestive, is nonspecific; GSs may be associated with acute cholecystitis which causes severe abdominal pain, N&V, fever, leukocytosis Diagnosis Ultrasonography, cholescintigraphy, cholecystography Management Laparoscopic cholecystectomy, percutaneous dissolution of gallstones by MTBE–methyl- tert-butyl ether, via a percutaneous transcutaneous catheter, shock-wave lithotripsy.

The symptoms may occur after a fatty meal and may be associated with nausea or vomiting or fever. Jaundice may be present on physical examination. TreatmentAsymptomatic gallstones are neither removed nor treated. Symptomatic gallstone disease is treated primarily in the U.S. by laparoscopic cholecystectomy which, when successful, avoids prolonged hospitalization. Drug therapy for gallstones may include the use of ursodiol. Stones found in the extrahepatic bile ducts are treated surgically according to the presentation. Cholecystotomy is reserved for patients who are judged to be too ill to tolerate cholecystectomy, usually as a temporizing procedure. Gallstone lithotripsy is infrequently used because it is technically more complex than laparoscopic cholecystectomy (and relatively equipment and labor is intensive, and less universally effective). CAUTION!Ursodiol (ursodeoxycholic acid), taken orally, is sometimes effective in treating cholesterol gallstones. Treatment may need to be continued for 1 year. A similar agent, chenodiol, is no longer available as it caused unacceptable incidence of hepatotoxicity.Patient discussion about gallstoneQ.
