Hipomotilidade da vesícula biliar em pacientes colectomizados por retocolite ulcerativa inespecífica / Hipomotilidade da vesícula biliar em pacientes colectomizados por retocolite ulcerativa inespecífica

Aderson Omar Mourão Cintra Damião 10 November 1995 (has links)
Pacientes com retocolite ulcerativa inespecífica,quando submetidos à colectomia, apresentam aumento na freqüência de cálculos vesiculares de colesterol. A hipomotilidade da vesícula biliar tem sido apontada como um importante fator na formação dos cálculos vesiculares de colesterol, ao lado da supersaturação biliar de colesterol e da nucleação dos cristais de colesterol (fatores nucleantes e antinucleantes). A estase vesicular aumenta o tempo de reabsorção de água pela mucosa da vesícula biliar com conseqüente superconcentração dos solutos, além de gerar o tempo necessário para a nucleação do colesterol, retenção e fusão dos cristais e,finalmente,formação dos cálculos. Embora a composição biliar já tenha sido estudada em pacientes colectornizados, não há informações sobre o comportamento da motilidade da vesícula biliar em pacientes com retocolite ulcerativa inespecífica com e sem colectomia. No presente trabalho,o esvaziamento vesicular foi estudado através do método ultra-sonográfico e após ingestão de dieta líqüida gordurosa em indivíduos controles (n=40), pacientes com retocolite ulcerativa inespecífica sem (n=30) e com colectomia (n =20). Como o esvaziamento gástrico pode interferir no vesicular, o tempo de esvaziamento gástrico, medido por método ultra-sonográfico, foi calculado nos três grupos. O esvaziamento vesicular foi significantemente diminuído nos pacientes com retocolite ulcerativa inespecífica com colectomia e após estímulo alimentar: esta alteração não foi conseqüência de esvaziamento gástrico retardado pois o tempo de esvaziamento gástrico foi semelhante nos três grupos. Ademais, a redução da motilidade vesicular nos pacientes colectomizados relacionou-se com a colectomia propriamente dita, uma vez que indivíduos controles e pacientes com retocolite ulcerativa inespecífica sem colectomia apresentaram esvaziamentos vesiculares semelhantes. Além disso,os resultados desta investigação reforçam a relevância do papel da motilidade vesicular na colelitíase e sua participação, juntamente com a diminuição do \"pool\" de ácidos biliares,na patogênese da calculo se vesicular de colesterol em pacientes com retocolite ulcerativa inespecífica submetidos à colectomia. / Patients with ulcerative colitis, who have their colon removed, are at increased risk of developing cholesterol gallstones. Gallbladder hypomotility has been quoted as being an important factor for cholesterol gallstone formation, together with biliary supersaturation of cholesterol and nucleation of cholesterol crystals (nucleating and antinucleating factors). Gallbladder stasis increases the time for water reabsorption by the gallbladder mucosa with ensuing solute superconcentration; moreover, gallbladder stasis renders enough time for cholesterol nucleation. crystal retention and fusion, and finally, stone formation. Although bile composition, in these patients, has already been studied, there is no information concerning the nature of gallbladder motility in patients with ulcerative colitis with or without colectomy. ln the present work, gallbladder emptying was studied by means of ultrasound examination, and after ingestion of a standard liquid fatty meal in controls (n=40), ulcerative colitis patients without colectomy (n=30) and with colectomy (n=20). Also, in order to rule out the influence of gastric emptying on gallbladder motility, the gastric emptying time was calculated, in the three groups, using the ultrasound method. Gallbladder emptying was significantly impaired in patients with ulcerative colitis with colectomy after a fatty-meal stimulus. and this abnormality was not a consequence of delayed gastric ernptying. since gastric emptying time was similar in the three groups. Furthermore. impaired gallbladder motility in ulcerative colitis patients with colectomy was related to the colectorny itself, since controls and ulcerative colitis

Prä- und postoperative Untersuchungen bei Hunden mit angeborenem Portosystemischen Shunt unter besonderer Berücksichtigung der Serumgallensäurenkonzentration nach Stimulation mit Ceruletid

Schmidt, Peter 28 November 2004 (has links) (PDF)
Es wurden 44 Hunde mit einem kongenitalen Portosystemischen Shunt präoperativ hinsichtlich ihrer Leberzellintegrität (ALT, AP, GLDH, GGT) und ihrer hepatischen Synthese- (Harnstoff, Cholesterin, Albumin) bzw. Metabolisierungsrate (Ammoniak) untersucht. Die hepatische Durchblutungs- und Resorptionsrate wurde anhand des Verlaufs der Serumgallensäuren im Gallensäuren-Stimulationstest mit Ceruletid (0,3µg/kg KM i.v.)vor und 30 min nach Stimulation (FSBA; PSBA) beurteilt. Eine Verlaufsuntersuchung erfolgte bei den Hunden, bei denen das Shuntgefäß in zwei Operationen verschlossen worden war. Die Untersuchungen wurden jeweils prae operationem, am zweiten, vierten und siebten Tag post operationem sowie abschließend mindestens 120 Tage nach vollständigem Verschluss des Shuntgefäßes durchgeführt. Es wurden die Ergebnisse der einzelnen Untersuchungstage untereinander mit Hilfe des gepaarten t-Tests sowie mit einer Kontrollgruppe (63 lebergesunde Hunde)unter Anwendung des unpaaren t-Tests verglichen. / The hepatic enzymes: alanine aminotransferase (ALT), alkaline phosphatase (AP), glutamat dehydrogenase (GLDH), gamma-glutamyl transferase (GGT); the hepatic synthetic (urea, cholesterol, albumin) and metabolic activity (ammonia) and the hepatic blood flow (serum bile acid stimulation test) were determined in 44 dogs with congeintal portosystemic shunt and in 63 healthy dogs. After determination of fasting serum bile acids (FSBA), the gallbladder contraction was induced by administration of 0,3µg/kg iv ceruletide (Takus). Blood samples of the poststimulatin serum bile acids (PSBA) were taken 30 minutes post administration. The portosystemic shunt was first attenuated (surgery 1) and 4 weeks later completely ligated (surgery 2). All dogs treated with this surgical procedure were examined with the described laboratory design before surgery, the second, the fourth, the seventh day after surgery and approxiamtely 120 days after complete ligation in a follow up study. To compare the developmentof the biochemical and hepatic alterations the paired and unpaired t-test were used.

Prevalência, fatores de risco e marcadores bioquímicos em cães com lama biliar diagnosticada por ultrassonografia / Prevalence, risk factors and biochemical markers in dogs with ultrasound diagnosed biliary sludge

Secchi, Priscila January 2011 (has links)
A lama biliar em cães é considerada um achado incidental, sendo frequentemente identificada durante ultrassonografias abdominais como sedimento ecogênico de baixa amplitude sem sombra acústica e com mobilidade gravidade dependente. Em humanos, a presença de lama biliar é considerada anormal e está associada a diversas situações clínicas e complicações como cálculos biliares, colangite e pancreatite aguda. Em cães sua importância clínica ainda é desconhecida. Os objetivos deste estudo foram estimar a prevalência, avaliar fatores de risco, alterações encontradas ao exame de ultrassom e marcadores bioquímicos em cães com lama biliar diagnosticada por ultrassonografia. Determinou-se a prevalência e a influência das diferentes raças, sexo e idade na lama biliar, a partir de 1.021 cães submetidos à ultrassonografia abdominal, independente do estado de saúde. Desse total, foram selecionados por conveniência, 100 cães para avaliação das alterações encontradas na ultrassonografia, dos fatores de risco e dos marcadores bioquímicos perante a presença ou ausência de lama biliar. Os resultados mostraram que a prevalência de lama biliar é alta, sendo que cães com 10 anos ou mais estiveram mais predispostos. Machos e fêmeas foram acometidos em igual intensidade, havendo uma maior prevalência nas raças Beagle, Cocker Spaniel e Poodle. Nenhum dos marcadores bioquímicos estudados demonstrou correlação significativa com a lama e através da quantificação desse sedimento foi possível sugerir que o espessamento biliar raramente progride podendo acarretar complicações mais graves como a mucocele e colelitíase. Condição corporal e a castração não demonstraram relação com a presença de lama biliar e o tipo de dieta não foi considerado como o principal fator de risco, havendo apenas fraca associação da lama com o abuso da alimentação com petiscos veterinários. Já o uso de medicamentos demonstrou estar entre as possíveis causas para o desenvolvimento do espessamento biliar. Pacientes com doenças cardiovasculares encotraram-se no grupo de risco e a maior ocorrência de hepatomegalia nos cães acometidos pela lama foi associada à congestão hepática passiva, consequência das cardiopatias. Acredita-se que o fator idade também possa estar relacionado a esse fato, já que as cardiopatias são mais frequentes em cães mais velhos. / The biliary sludge in dogs is deemed to be an incidental finding, and is often identified during abdominal ultrasound as echogenic sediment of low amplitude without acoustic shadowing and gravity dependent mobility. In humans, the presence of biliary sludge is considered abnormal and it is associated with various medical conditions and complications such as gallstones, cholangitis and acute pancreatitis. In dogs their clinical importance is still unknown. The aims of this study were to estimate prevalence, evaluate risk factors, findings on ultrasound examination and biochemical markers in dogs with biliary sludge diagnosed by ultrasonography. It was determined the prevalence and influence of different breeds, gender and age in biliary sludge, from 1.021 dogs undergoing abdominal ultrasonography, regardless of their health status. Overall, it was selected for convenience, 100 dogs for evaluation of abnormalities found on ultrasound, the risk factors and biochemical markers before the presence or absence of biliary sludge. The results showed that the prevalence of biliary sludge is high, and dogs with 10 years old or more were more predisposed. Males and females were affected at the same intensity, with greater prevalence in breeds Beagle, Cocker Spaniel and Poodle. None of the biochemical markers studied showed a significant correlation with the sludge and through the quantification of sediment was possible to suggest that the thickened bile rarely progresses and may cause more serious complications such as mucocele and cholelithiasis. Body condition and castration showed no correlation with the presence of biliary sludge and the type of diet was not considered a major risk factor, with only a weak association of the sludge with the abuse with veterinarians’ snacks. But the use of medicines proved to be among the possible causes for the development of the thickened bile. Patients with cardiovascular diseases lay in the risk group and higher incidence of hepatomegaly in dogs affected by the mud was associated to passive hepatic congestion, as consequence of cardiopathies. It is believed that the age factor may also be related to this fact, since cardiopathies are more common in older dogs.

Title: Using of alternative therapeutic techniques to vertebrovisceral links of liver and gallbladder diseases Objectives: The aim of this thesis is to find out a sufficient amount of information on the subject of functional liver and gallbladder diseases, possibilities of conventional treatment and alternative treatment options. Another goal of this thesis is to compile an assessment protocol, based on the theoretical background, according to which it is possible to diagnose patients with functional liver and gallbladder diseases. An additional goal of this thesis is to create a treatment concept for patients with functional liver and gallbladder diseases. This treatment concept will be based on the knowledge of yoga and traditional Chinese medicine. Last goal is to compare conventional physiotherapy with the concept created. Methods: The theoretical part of this thesis focuses on the issue of functional disease of liver and gallbladder. In takes into account the current research and data found in Czech and foreign literature. The practical part looks into the effects of complex therapy methods using experiments. The therapy itself includes changes of the patients' lifestyles, which are based on traditional Chinese medicine and yoga asanas, which were compiled for the purposes of this thesis for...
