Jaundice and/or clay-colored stool may raise suspicion of choledocholithiasis or even gallstone pancreatitis. [1] If the above symptoms coincide with fever and chills, the diagnosis of ascending cholangitis may also be considered. More than 70% of people with gallstones are asymptomatic and are diagnosed incidentally during ultrasound.
A Sonographic Murphy sign is a finding when performing diagnostic medical sonography.It is different from the Murphy sign found on physical examination, but both signs are associated with cholecystitis [1] When the sonographer presses directly over the gallbladder, and the patient expresses pain, more than when the sonographer presses anywhere else, this is said to be a positive sonographic ...
It shows a gallbladder wall that is almost pathologically thickened, at 3 mm. However, there is no apparent edema in the pericholecystic fat. The gallbladder contains biliary sludge, as well as gallstones, which create acoustic shadowing. There is thus gallstones without current cholecystitis.
A gallstone is a stone formed within the gallbladder from precipitated bile components. [2] The term cholelithiasis may refer to the presence of gallstones or to any disease caused by gallstones, [5] and choledocholithiasis refers to the presence of migrated gallstones within bile ducts.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
The presence of gallstones, usually visualized by ultrasound, generally necessitates a surgical treatment (removal of the gall bladder, typically via laparoscopy). [ 27 ] Removal of the gallbladder with surgery, known as a cholecystectomy , is the definitive surgical treatment for biliary colic.
Murphy's sign has a high sensitivity and negative predictive value, although the specificity is not high. [2] However, in the elderly the sensitivity is markedly lower; a negative Murphy's sign in an elderly person is not useful for ruling out cholecystitis if other tests and the clinical history suggest the diagnosis.
The pancreatic duct requires visualisation in cases of pancreatitis. Ultrasound is frequently the first investigation performed on admission; although it has little value in the diagnosis of pancreatitis or its complications. contrast-enhanced computed tomography (MD-CECT) is the most used imaging technique.
