Introduction: Early diagnosis of biliary atresia is very important for better outcome of treatment. Ultrasonography is one of the diagnostic tools for early differentiation of  biliary atresia from other causes of neonatal cholestasis. It has been reported that triangular cord sign  (TACS) in sonography is a reliable sign for diagnosis of biliary atresia. The aim of this study was to re-assess ...

biliary papillomatosis is a disorder characterized by numerous adenomatous polyps of variable distribution and extent in intrahepatic bile ducts. it should be considered as a premalignant condition because a high proportion of the lesions undergo malignant transformation. in this report, we present a patient with abdominal pain and jaundice. according to his presenting signs and symptoms, ercp ...

In humans, N-acetyl-5-methoxytryptamine (melatonin), a neurohormone widely found in plants and animal sources, is synthesized from serotonin primarily by the pineal gland. However, it it is also produced in a number of other areas, e.g. the gastrointestinal tract. Melatonin regulates various biological and physiologic body functions and its role in the regulation of circadian rhythms, particula...

OBJECTIVES To investigate the value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis between gallbladder adenomas and gallbladder adenomas canceration. METHODS CEUS data from 34 patients (25 patients with gallbladder adenomas and 9 patients with gallbladder adenomas canceration) were retrospectively analyzed, including the characteristics of contrast arrival time, time to ...

background: there are two kinds of ascites, cirrhotic and malignant. the conventional diagnostic method to differentiate them is paracentesis. this is an invasive and time consuming method. however, ultrasonography is an easy and available method to provide valuable results in a short period of time. the aim of this study was to evaluate gallbladder wall thickness in differentiating cirrhotic a...

The pathophysiology of canine gallbladder diseases, including biliary sludge, gallbladder mucoceles and gallstones, is poorly understood. This study aimed to evaluate the component of gallbladder contents and bacterial infection of the gallbladder in order to elucidate the pathophysiology of biliary sludge and gallbladder mucoceles. A total of 43 samples of canine gallbladder contents (biliary ...

Gallbladder polyps are frequently found on abdominal ultrasonography. Most gallbladder benign. However, the risk of malignancy increases when polyp size exceeds 10 mm. The fifth edition World Health Organization Classification tumors proposed three types preinvasive neoplasms gallbladder: adenoma, intracholecystic papillary neoplasm (ICPN), and biliary intraepithelial neoplasia (BilIN). Herein,...

Calcification of the gallbladder wall (porcelain gallbladder) is an intense structure and uncommon manifestation seen in chronic cholecystitis and resulting from chronic inflammation of the gallbladder wall. Patients with porcelain gallbladder are usually considered not at risk of acute cholecystitis. However, sporadic cases of cholecystitis on porcelain gallbladder have been described in liter...
