1. Perfuração espontânea da vesícula biliar com formação de biloma intra-hepático: sinais ultrassonográficos e correlação com tomografia computadorizada
A perfuração espontânea da vesícula biliar é uma complicação grave e pouco frequente da colecistite aguda, que exige diagnóstico rápido e preciso; a formação concomitante de coleções intra-hepáticas nesses casos é rara. O presente relato enfatiza a importância dos exames de imagem nesse contexto, demonstrando sinais ultrassonográficos e tomo

2. Colecistite aguda decorrente de hemorragia intraluminar da vesícula biliar após trauma abdominal fechado
Isolated gallbladder injury following abdominal blunt trauma is rare and early diagnosis is difficult to make, particularly when no other organ is injured. However, ultrasonography is valuable for investigating gallbladder injuries. We report a case of isolated gallbladder blunt trauma presented as acute cholecystitis with hemobilia. In isolated blunt trauma

3. Comparação entre a ultra-sonografia e a ressonância magnética do abdome na avaliação da morbidade na esquistossomose mansônica
There is no study comparing ultrasonography (US) to magnetic resonance imaging (MRI) in the evaluation of liver disease in patients with schistosomiasis mansoni, except for case reports. This study compared US and MRI of the abdomen in the evaluation of morbidity in schistosomiasis mansoni. Sixty patients (age 42,1 ± 13,4 years), attending the Hospital das

4. Colecistite aguda por ascaris lumbricoides
Biliary’s ascariasis is the most often ectopic site of this helminthiasis, but invasion of the worms into the gallbladder is quite rare. The autors report a case of a patient with clinical symptoms, compatible with cholecystitis induced by the worm, as shown by ultrasonography. Treatament was cholecystectomy and antihelmintic drug therapy with a good outco

5. Vesícula residual
Our objective is to report three patients with recurrent severe upper abdominal pain secondary to residual gallbladder. All patients had been subjected to cholecystectomy from 1 to 20 years before. The diagnosis was established after several episodes of severe upper abdominal pain by imaging exams: ultrasonography, tomography, or endoscopic retrograde cholan

6. Implante tumoral em sítio de trocarte após colecistectomia laparoscópica
The authors present two cases of unsuspected carcinoma of the gallbladder after laparoscopic cholecystectomy in which trocar site metastasis developed during their follow-up. In the first case, a 68 year-old woman with cholecystolithiasis underwent an uneventful laparoscopic cholecystectomy. Histologic examination revealed adenocarcinoma invading the mucosa

7. Ultra-sonografia do figado e das vias biliares em pacientes com fibrose cistica
This ultrasonographic study aimed to gain information on the relationship between, liver and gall bladder alterations and functions was carried out to compare the effects of cystic fibrosis (CF) in patients, ages 1-18 years old, representative of A group. The investigation was done through the analysis of ultrasonographic images of the liver and gall bladder

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

9. Intraoperative ultrasonography evaluation of the gallbladder in morbidly obese patients.
Intraoperative ultrasound evaluation of the gallbladder was performed in 55 morbidly obese patients undergoing gastric bariatric surgery. Cholecystectomy was performed in the presence of any physical or ultrasonographic abnormality. Eighteen patients (33%) had cholecystectomy. Nine patients had palpable gallbladder disease confirmed by ultrasound. Nine patie

10. Differential diagnosis of small polypoid lesions of the gallbladder: the value of endoscopic ultrasonography.
OBJECTIVE: To evaluate the accuracy of endoscopic ultrasonography (EUS) in making a differential diagnosis of small (< or =20 mm) polypoid lesions of the gallbladder. SUMMARY BACKGROUND DATA: Differential diagnosis of these lesions is often difficult using conventional imaging modalities. METHODS: The findings of EUS and transabdominal ultrasonography were r

12. The role of neurotensin in human gallbladder motility.
Gallbladder contraction in response to a fatty meal is thought to be caused by release of cholecystokinin (CCK). We have previously demonstrated a close correlation between circulating concentrations of CCK and contraction of the gallbladder in normal humans and in gallstone patients. Recent studies in animals, however, have shown that other potentially chol
