Failure of gallbladder visualisation during oral cholecystography when abnormal liver function returns to normal, or there is mild to moderate liver disease, maybe due to extrahepatic (outside the liver) causes. [4] Oral cholecystography can have better sensitivity and specificity in diagnosing acute and chronic gallbladder disease than ultrasound.
The investigation is usually conducted after an ultrasonographic examination of the abdominal right upper quadrant for a patient presenting with abdominal pain.If the noninvasive ultrasound examination fails to demonstrate gallstones, or other obstruction to the gallbladder or biliary tree, in an attempt to establish a cause of right upper quadrant pain, a cholescintigraphic scan can be ...
The gallbladder has a capacity of about 50 millilitres (1.8 imperial fluid ounces). [2] The gallbladder is shaped like a pear, with its tip opening into the cystic duct. [4] The gallbladder is divided into three sections: the fundus, body, and neck. The fundus is the rounded base, angled so that it faces the abdominal wall.
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 ...
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.
Before the procedure, bedside ultrasound is done to confirm the position of the dilated bile ducts in the liver. The puncture site is then marked. Bile ducts of the right liver is located in the intercostal spaces between anterior and mid axillary lines.
The gallbladder can also be removed in order to treat biliary dyskinesia or gallbladder cancer. [7] Gallstones are very common but 50–80% of people with gallstones are asymptomatic and do not need surgery; their stones are noticed incidentally on imaging tests of the abdomen (such as ultrasound or CT) done for some other reason. [8]
Most polyps are benign and do not need to be removed. Surgical removal of the gallbladder (cholecystectomy) is recommended when a gallbladder polyp larger than 1 cm is found, even if the person has no symptoms clearly related to the polyp. Laparoscopic surgery is an option for small or solitary polyps. [citation needed]
