Golding, MD,t Peter L Cooperberg, MD Echogenic bile or biliary sludge is a well-recog nized sonographic finding in the gallbladder. Complete evaluation of the liver requires extensive examination of all aspects of the liver and may also necessitate both standard transabdominal and intercostal (between the ribs within the intercostal space) approaches. 1. 2009 Oct;70(4):786-92. doi: 10.1016/j.gie.2009.04.049. Abstract Background: Possible mass lesions identified on ultrasound (US) of the gallbladder may prompt an aggressive surgical intervention due to the possibility of a malignant neoplasm. In response to the detection of ingested fat, gallbladder contraction is signaled by way of a neurohormonal pathway that results in prompt excretion of the biliary payload. Das R, Zeh H, Zureikat A, Slivka A, Papachristou GI. In general, most pathological processes affecting the gallbladder will cause thickening, either due to inflammation or due to precipitation of bile contents due to prolonged stasis. Abdominal ultrasound is the obvious study of choice to evaluate acute gallbladder disease. Abscesses associated with dropped gallstones are usually treated by surgery rather than percutaneous drainage to remove all gallstones, which can act as a nidus for recurrent infections . Gray's Anatomy. Gallbladder carcinoma may appear at any of these imaging modalities as (Fig.1): 1. Gastrointest Endosc Clin N Am. 6. We present two cases of persistent gallbladder fossa fluid collections which were refractory to bile duct decompression but which were successfully drained by endoscopic ultrasound-guided endoprosthesis placement. Gallbladder sludge forms when bile remains in the gallbladder for too long. This site needs JavaScript to work properly. There are extensive capillaries and small venules, but absent lymphatics 4. The gallbladder communicates with the rest of the biliary system by way of the cystic duct, with bidirectional drainage of bile to and from the common hepatic duct. It shows increased echogenicity and coarsened echotexture. 2018 Dec 19;5:e100. 9. "there is a 2.9 x 1.9 cm multiobulated t2 hyperintense hepatic lesion just above the gallbladder fossa.

The gallbladder was not visualized, but strong echoes with acoustic shadowing were seen, suggesting a contracted gallbladder. Imaging modalities used in evaluating gallbladder diseases include ultrasonography, endoscopic ultrasonography, computer tomography, and MRI (26). Talley NJ, Lindor KD, Vargas HE. (1918) ISBN:1587341026. Unlike other foregut-derived organs, the lamina propria and muscular layers are directly apposed because there are no submucosal or muscularis mucosae layers 4,6. For descriptive purposes, it may be divided into the following segments 6: The gallbladder is closely apposed to the liver within the fossa. The diagnosis is made on imaging studies. The gallbladder concentrates bile using mechanism of active transport of sodium and chloride, effectively removing water and slightly increasing acidity of bile. The anatomy of general surgical operations. Fig. Ultrasonography (US) is the method of choice for detection of gallstones.

The gallbladder fossa was considered expanded if there was an enlargement of the pericholecystic space, and the space was bounded laterally by the edge of the right hepatic lobe, Evidence of a cholecystectomy is often seen on imaging procedures with surgical clips in the gallbladder fossa and radiologists should be aware of possible complications. There is no single cystic vein, but rather the gallbladder drains directly into the venous system of the liver through the gallbladder fossa (cystic veins) and by a number of veins into the right branch of the portal vein 2.
