Most people with gallstones (about 80%) are asymptomatic. [2] [3] However, when a gallstone obstructs the bile duct and causes acute cholestasis, a reflexive smooth muscle spasm often occurs, resulting in an intense cramp-like visceral pain in the right upper part of the abdomen known as a biliary colic (or "gallbladder attack"). [4]
It is a diagnosis of exclusion which means other possible urinary diseases which could cause bladder inflammation (e.g. feline urinary tract infections or urolithiasis) are ruled out. [5] Research is still being pursued regarding the causes of cystitis in cats, though the following principal risk factors have been identified: [14]
With these direct connections, gallstones can pass from the gallbladder to the intestines. Gallstones can get trapped in the gastrointestinal tract, most commonly at the connection between the small and large intestines (ileocecal valve).
Common bile duct stone, also known as choledocholithiasis, is the presence of gallstones in the common bile duct (CBD) (thus choledocho-+ lithiasis). This condition can cause jaundice and liver cell damage. Treatments include choledocholithotomy and endoscopic retrograde cholangiopancreatography (ERCP).
As with mild pancreatitis, it will be necessary to treat the underlying cause—gallstones, discontinuing medications, cessation of alcohol, etc. If the cause is gallstones, it is likely that an ERCP procedure or removal of the gallbladder will be recommended. There is also evidence that, even for patients without gallstones, surgical removal ...
Bile duct obstruction, which is usually present in acute cholangitis, is generally due to gallstones. 10–30% of cases, however, are due to other causes such as benign stricturing (narrowing of the bile duct without an underlying tumor), postoperative damage or an altered structure of the bile ducts such as narrowing at the site of an anastomosis (surgical connection), various tumors (cancer ...
The exact cause of lentigo in cats is not well understood, but it is believed to be linked to genetics. As a result, the condition is more prevalent in certain cat colors or patterns.
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.
