Prevalência ultra-sonográfica de litíase biliar em pacientes ambulatoriais

Abstract: INTRODUÇÃOA doença calculosa da vesícula biliar continua sendo um problema de saúde de proporções variadas em todo o mundo. Sua prevalência varia de acordo com as populações estudadas, tanto retrospectivamente em necropsias, quanto prospectivamente através do exame ultra-sonográfico. Estima-se que 25 milhões de pessoas nos Estados Unidos sejam portadoras de litíase biliar, onde são diagnosticados um milhão de casos novos por ano, o que resulta em 600 mil operações nesse período. Por outro lado, a prevalência d… Show more

“…In this context, the histopathological examination of gallbladder specimens is an important step to confirm the diagnosis 1 . Evidence that this disease is more common after emergency cholecystectomy has also been shown in other studies, such as the one by Torres et al 12 , which has suggested that prolonged chronic gallbladder stress, which occurs in symptomatic patients who are submitted to emergency surgery, increases the exposure time to oncogenes and the degree of epithelial dysplasia.…”

“…In questionable cases or require additional supporting information, or, even, for differential diagnosis, the interpretation of clinical signs should always be correlated with laboratory tests, ultrasound exams or other methods of diagnostic imaging 2,13,47,51,52 . Ultrasound is a practical technique, fast and inexpensive, being considered as a screening assay in the initial evaluation of patients with suspected hepatobiliary tract disorders 7,8,12,13,53 , mainly due to its high sensitivity and specificity 1,16 . Through this examination, can visualize hepatomegaly in cases of cholestasis associated with obstruction, with the characteristic signs of increased volume of the organ and the presence of smooth margins, and there may be diffuse and increased echogenicity, and inadequate definition of the portal vessels; in biliary tract, is more common visualization increase of size in the gallbladder and dilation of ducts 12,16,17 .…”

“…The main risk factors for the development of gallstones in humans are age, heredity, parity and obesity; occurring mainly in people over 55 years, and a greater incidence among women [5][6][7][8] . There are several conditions that, in humans and animals, can cause obstruction in the biliary tree, occurring cholestasis [9][10][11][12][13] .…”
