Gallstones and biliary sludge, but the gallbladder wall is not clearly thickened, with no edema in the pericholecystic fat, thus not cholecystitis. Acute cholecystitis as seen on ultrasound. The closed arrow points to gallbladder wall thickening.
If gallstones are blocking other biliary tract areas causing pancreatic gallstones or choledocholithiasis, elevated liver panel, pancreatic enzymes, and bilirubin will be noted. [1] [2] Ultrasound is the diagnostic imaging of choice to examine for thickening of the gallbladder walls, polyps, pericholecystic fluid, and gallstones.
Biliary colic, also known as symptomatic cholelithiasis, a gallbladder attack or gallstone attack, is when a colic (sudden pain) occurs due to a gallstone temporarily blocking the cystic duct. [1] Typically, the pain is in the right upper part of the abdomen, and can be severe. [2] Pain usually lasts from 15 minutes to a few hours. [1]
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.
The gallbladder wall is composed of a number of layers. The innermost surface of the gallbladder wall is lined by a single layer of columnar cells with a brush border of microvilli, very similar to intestinal absorptive cells. [2] Underneath the epithelium is an underlying lamina propria, a muscular layer, an outer perimuscular layer and serosa.
Biliary microlithiasis refers to the creation of small gallstones less than 3 mm in diameter in the biliary duct or gallbladder. It has been suggested [1] as a cause of postcholecystectomy syndrome, or PCS, the symptoms of which include: Upset stomach, nausea, and vomiting. Gas, bloating, and diarrhea. Persistent pain in the upper right abdomen ...
The normal thickness of the small intestinal wall is 3–5 mm, [8] and 1–5 mm in the large intestine. [9] Focal, irregular and asymmetrical gastrointestinal wall thickening on CT scan suggests a malignancy. [9] Segmental or diffuse gastrointestinal wall thickening is most often due to ischemic, inflammatory or infectious disease. [9]
Courvoisier's sign occurs due to the gradual (chronic) nature of the obstruction caused by cancer (e.g. pancreatic, often located in pancreatic head, cholangiocarcinoma, etc.), which gradually causes biliary back-pressure and gradually distends the gallbladder over time, without causing acute damage, thus without causing pain. Conversely ...
