The use of cholescintigraphy to diagnose acute cholecystitis, biliary obstruction, and biliary leakage dates back to the late 1970s. Today, despite the many advances in imaging instrumentation, radiopharmaceuticals, and methodology over these years, cholescintigraphy still plays an important role in confirming or excluding these diagnoses in acutely ill patients. Acute calculous and acalculous ...

OBJECTIVE The purpose of this study was to investigate the postprandial gallbladder motility of cirrhotic patients using cholescintigraphy by technetium-99m-ethylhydroiminodiacetic acid ((99m)Tc-EHIDA). SUBJECTS AND METHODS Sixty two cirrhotic patients (Child-Pugh A: 28 patients; Child-Pugh B: 21 and Child-Pugh C: 13 patients) and 24 normal subjects were included in this study. All patients u...

Cholescintigraphy has traditionally been used as a tool to select patients with biliary pain for elective cholecystectomy. However, atypical biliary pain presents a clinical challenge and there is no literature evaluating the factors of the gallbladder (GB) wall related to abnormal ejection fraction of cholescintigraphy in such patients. Therefore, we aimed to evaluate characteristics of the GB...

Objective. Contractility of gallbladder is known to be decreased in fatty gallbladder diseases. However, clinical estimation data about this relationship is still lacking. The aim of this study was to investigate the association between steatocholecystitis and contractility of gallbladder. Methods. Patients with cholecystitis (steatocholecystitis versus nonsteatocholecystitis) who underwent cho...

UNLABELLED The purpose of this investigation was to evaluate the use of a commercially available lactose-free fatty-meal food supplement, as an alternative to sincalide cholescintigraphy, to develop a standard methodology, and to determine normal gallbladder ejection fractions (GBEFs) for this supplement. METHODS Twenty healthy volunteers all had negative medical histories for hepatobiliary a...

Chronic acalculous gallbladder and chronic acalculous biliary disease are considered functional hepatobiliary diseases. Cholescintigraphy provides physiologic imaging of biliary drainage, making it ideally suited for their noninvasive diagnosis. For chronic acalculous gallbladder disease, calculation of a gallbladder ejection fraction during sincalide cholescintigraphy can confirm the clinical ...

Chronic acalculous cholecystits typically presents with biliary symptoms, normal blood tests and unremarkable ultrasound, computerized tomography and magnetic resonance cholangiopancreatography. However, cholescintigraphy may show reduced gallbladder ejection fraction (GBEF). There are no reports on using ultrasound to measure GBEF in adults. Twenty-eight patients with the above presentation un...

PURPOSE To update previously summarized estimates of diagnostic accuracy for acute cholecystitis and to obtain summary estimates for more recently introduced modalities. MATERIALS AND METHODS A systematic search was performed in MEDLINE, EMBASE, Cochrane Library, and CINAHL databases up to March 2011 to identify studies about evaluation of imaging modalities in patients who were suspected of ...
