When bile duct dilatation is associated with clinical symptoms or cholestasis, the aetiology must continue to be sought using MRCP combined with MRI exploration in slices without and after gadolinium injection [11] and/or endoscopic ultrasonography, the latter being very effective in this context [12...
High bile duct obstruction is best approached percutaneously, as using ultrasound andfluoroscopyguidance a specific duct can be targeted to optimize the amount of functional parenchyma that is drained. Conversely, dilated ducts in atrophic segments or segments with high tumor burden can be purposefully...
The most common cause of an obstruction in the biliary tree is abile duct stone(choledocholithiasis). This includes a stone or stones lodged in the common hepatic, cystic or common bile ducts. The causes, symptoms and treatment is discussed further underBile Duct Stones. Ask a Doctor Online ...
should choose their patients, and the ideal timing of cholecystectomy, putting in mind the possible risks that would be encountered; for instance, performing a cholecystectomy for a patient with acute cholecystitis should be within 48 h and no more than 10 days after the onset of symptoms [9]...
Unchanged size of a dilated common bile duct after a fatty meal: results and significance. Sonographic measurement of common bile duct caliber alone is insufficient to ascertain the presence of obstruction. Fatty meal stimulation significantly improves diagnostic accuracy. An increase in caliber of a ...
A 62-year-old man with a 20-year history of chronic ulcerative colitis and a 9-year history of primary sclerosing cholangitis (PSC) underwent orthotopic liver transplantation because of symptoms related to PSC and cholangiographic features compatible with a biliary neoplasm. Study of the excised ...
Congenital cysts of the common bile duct (CBD) are rare. Mostly they are found in children and do not typically lead to the formation of common bile duct stones. It is uncertain whether primary CBD stones and acquired choledochal cysts exist. We present an 80-year-old woman presented with ...
bile duct stone passage based on stone disappearance 6 weeks after diagnosis, as determined in one study by cholangiograms using an in situ cholangiogram catheter[25]. Given the potential serious complications of bile duct stones, specific therapy generally is indicated regardless of symptoms. ...
Ultrasound (US) is the initial screening modality of choice and has been shown to be accurate in demonstrating the presence of dilated bile ducts, as well as the level and cause of obstruction. For adequate radiological communication to the clinician, degree of bile duct dilatation,......
Animals are fed control and bile acid-supplemented diets and monitored daily for weight loss and weekly for serum indicators of liver function to detect symptoms of cholestasis such as elevated liver enzymes in blood, as well as elevated bile salts and/or bilirubin (Table 1). Bile duct ...
