Espessamento parietal da vesícula biliar no exame ultrassonográfico: como interpretar?

Abstract

The present review was aimed at providing help for correct interpretation of gallbladder wall thickening and differential diagnosis at ultrasonography. Gallbladder wall thickening is a frequent sonographic finding and has been subject of great interest for being considered as a hallmark feature of acute cholecystitis, despite the fact that such a finding is observed in a number of other medical conditions. An appropriate characterization and interpretation of this finding is of great importance, considering that the correct diagnosis has a direct impact on the treatment that in some cases includes surgery. In the present article, the authors describe a set of sonographic signs that, in association with clinical and laboratory findings can reduce the number of diagnostic hypotheses allowing a more accurate establishment of the cause for gallbladder wall thickening through a rational data evaluation. Keywords: Gallbladder; Ultrasonography; Inflammation; Neoplasm.O objetivo desta revisão é fornecer auxílio na interpretação correta do espessamento das paredes da vesícula biliar e seus possíveis diagnósticos diferenciais. O espessamento da vesícula biliar é um achado frequente em exame de ultrassonografia e um tema de grande interesse, por ter sido considerado durante muito tempo como sinal específico de colecistite aguda, apesar de se reconhecer que ocorre em uma série de outras situações clínicas. A adequada caracterização e interpretação desse achado é de grande importância, pois o diagnóstico correto tem impacto direto no tratamento, que em alguns casos inclui intervenção cirúrgica. Neste artigo procuramos apresentar um conjunto de sinais ultrassonográficos que, associados ao quadro clínico e laboratorial do paciente, permitem restringir as alternativas diagnósticas e estabelecer, com maior precisão, a causa do espessamento parietal da vesícula biliar, através de uma avaliação racional dos dados obtidos. Unitermos: Vesícula biliar; Ultrassonografia; Inflamação; Neoplasia. Abstract Resumo* Study developed at the

A Whole-Food-Based Health Product (A-F Betafood®) Improves Gallbladder Function in Humans at Risk of Gallbladder Insufficiency: A Randomized, Placebo-Controlled Clinical Trial

“…Gallbladder wall thickness influences motility of the gallbladder, with a reduction in wall thickness leading to improved functionality [16]. Participants enrolled in this study had a gallbladder wall thickness of less than 3 mm, as wall thickness greater than 3 mm is associated with impaired gallbladder function [16]. In this study, consumption of A-F Betafood ® for 12 weeks resulted in a significant reduction in gallbladder wall thickness compared to placebo.…”

“…Given the significant economic burden associated with gallbladder function, the discovery of a preventative approach is in high demand [15]. Gallbladder wall thickness influences motility of the gallbladder, with a reduction in wall thickness leading to improved functionality [16]. Participants enrolled in this study had a gallbladder wall thickness of less than 3 mm, as wall thickness greater than 3 mm is associated with impaired gallbladder function [16].…”

Estudo ultrassonográfico morfométrico do fígado e trato biliar de suínos submetidos a obstrução biliar experimental

“…The imaging evaluation, particularly by ultrasonography (US) of the liver and biliary tract has been the object of a number of recent articles in the Brazilian radiological literature (12)(13)(14)(15)(16)(17)(18) . US represents the most utilized imaging method in the primary evaluation of patients with suspected biliary obstruction (4,8,9) .…”

Por que parte da especialidade está sendo relegada a segundo plano dentro do diagnóstico por imagem?

“…One is very gratified and happy to see that very interesting studies on those imaging methods are being developed and published. Here are some of them: Abdominal gossypiboma (1) , four beautiful case reports (2)(3)(4)(5) , gallbladder wall thickening (6) , correlation between PSA and prostate cancer (7) , study of cerebral ventricles (8) , BI-RADS US (9) , abnormal uterine bleeding (10) , intima-media complex in atherosclerosis (11) , comparison between US and MRI in the portal flow assessment (12) , endoleaks in the endovascular management of aortic aneurysms (13) , abnormalities in the first trimester of pregnancy (14) , radiographic findings in the treatment of pulmonary paracoccidioidomycosis (15) , neurofibromatosis (16) , study of the spine after cervical traction (17) , and finally, three articles about medical physics (18)(19)(20) .…”
