A severe pain in the upper right quadrant of the abdomen that is usually caused by the gallbladder’s attempts to expel gallstones or by the movement of a stone in the bile ducts. The pain may be felt in the right shoulder (see referred pain) or may penetrate to the centre of the back. Episodes of biliary colic often last for several hours and may recur, particularly after meals.
Injections of an analgesic drug and an antispasmodic drug may be given to relieve the colic.
Tests such as cholecystography or ultrasound scanning can confirm the presence of gallstones, in which case cholecystectomy (surgical removal of the gallbladder) is possible.
Severe pain caused by the attempted (and sometimes successful) expulsion of a gall-stone from the gall-bladder via the BILE DUCT. The pain, which is felt in the upper right corner of the abdomen, may last for an hour or more. Strong ANALGESICS are required to subdue the pain and the patient may need hospital admission for examination and eventual surgery. Attacks may recur, and the pain is sometimes mistakenly diagnosed as signalling a heart attack.
See CHOLECYSTITIS, CHOLECYSTALGIA, etc.
severe abdominal pain resulting from obstruction of the cystic duct or common bile duct by (most commonly) a gallstone. The pain is felt in the right upper quadrant of the abdomen but may be poorly localized due to its visceral nature. It often occurs about an hour after a meal (particularly if fatty), may last several hours, and is usually constant in severity (unlike other forms of *colic). Vomiting often occurs.
