Abstract: background: the aim of this study is to compare eus and the others diagnostics tests in the correct localization of insulinomas. methods: we prospectively investigated 30 patients with endoscopic ultrasound with a clinical diagnosis of insulinomas prior to surgical exploration. they were submitted to abdominal ultrasonography, spiral computed tomography and four patients were submitted to magnetic ressonance before eus. surgery was the gold standard for tumor localization. results: twenty-six tumors were benign (86.6%) and four were malign (13.4%). the median size tumors detected by eus was 1.5 cm. the overall sensitivity of eus in identifying insulinomas was 86.6% compared to 33% for ct, 40% to mri and 90.9% to ius. in 12 patients we were able to perform eus-guided fine needle aspiration. insulinoma was diagnosed in ten cytological specimens (83.3%). tumors located in the head and body of the pancreas were seen by eus in all patients, respectively but those located in the tail were diagnosed only in 55.5% of the cases. conclusions: eus has a high sensibility in the identification and localization of pancreatic insulinomas and should replace traditional methods of image when clinical suspicion is high.

Abstract: objectives: to disseminate transesophageal ultrasound-guided fine needle aspiration (eus-fna) as an alternative to investigate mediastinal tumoral lesions because it is an underused modality that has been available in brazil for more than 15 years. methods: descriptive analysis of a single endoscopy service's experience since 1997 in the accomplishment of eusfna for mediastinal staging of previously known malignancies (group 1) or diagnostic definition of suspect lymph nodes and masses (group 2). results: eus-fna was performed in 51 patients between 26 and 87 years of age. the diameter of the lesions ranged between 1.1 and 9.8 cm (mean 3.9 cm). their location corresponded to the following stations: higher paratracheal (4 cases), lower paratracheal (7), aortic window (12), para-aortic (6), subcarinal (9), paraesophageal (8), and hilar (5). in group 1, 17 patients had previously diagnosed primary lung (9), breast (4), kidney (2), colon (1), and bladder (1) cancer. fifteen of these punctures were positive for malignity. two others were later submitted to mediastinoscopy, which identified metastases not detected by eus-fna. group 2 comprised 34 patients. among these patients, eus-fna diagnosed 22 neoplasms, five cases of tuberculosis and two duplication cysts. cytology was inconclusive or without a specific diagnosis in five other cases. mediastinoscopy identified two undiagnosed cases of oat-cell carcinoma, one lymphoma and one cryptococcosis, and confirmed one reactive lymphadenitis. there were no complications related to the method. conclusions: eus-fna obviated the need for surgical procedures in 86.3% of cases. therefore, oncologists, pulmonologists, and thoracic surgeons should always remember the technique's potential and availability.

Revista da Associa??o Médica Brasileira , 2010, DOI: 10.1590/S0104-42302010000100011
Abstract: objectives: causes may be found in most cases of acute pancreatitis, however no etiology is found by clinical, biological and imaging investigations in 30% of these cases. our objective was to evaluate results from endoscopic ultrasonography (eus) for diagnosis of gallbladder microlithiasis in patients with unexplained (idiopathic) acute pancreatitis. methods: thirty-six consecutive non-alcoholic patients with diagnoses of acute pancreatitis were studied over a five-year period. none of them showed signs of gallstones on transabdominal ultrasound or tomography. we performed eus within one week of diagnosing acute pancreatitis. diagnosis of gallbladder microlithiasis on eus was based upon findings of hyperechoic signals of 0.5-3.0 mm, with or without acoustic shadowing. all patients (36 cases) underwent cholecystectomy, in accordance with indication from the attending physician or based upon eus diagnosis. results: twenty-seven patients (75%) had microlithiasis confirmed by histology and nine did not (25%). eus findings were positive in twenty-five. two patients had acute cholecystitis diagnosed at eus that was confirmed by surgical and histological findings. in two patients, eus showed cholesterolosis and pathological analysis disclosed stones not detected by eus. eus diagnosed microlithiasis in four cases not confirmed by surgical treatment. in our study, sensitivity, specificity and positive and negative predictive values to identify gallbladder microlithiasis (with 95% confidence interval) were 92.6% (74.2-98.7%), 55.6% (22.7-84.7%), 86.2% (67.4-95.5%) and 71.4% (30.3-94.9%), respectively. overall eus accuracy was 83.2%. conclusions: eus is a very reliable procedure to diagnose gallbladder microlithiasis and should be used for the management of patients with unexplained acute pancreatitis. this procedure should be part of advanced endoscopic evaluation.

Abstract: context: the identification of a bulging covered by normal epithelium is a common finding during an upper gastrointestinal endoscopy. objective: to compare the endoscopic and endosonography findings in the differential diagnosis of the gastrointestinal bulging (subepithelial tumor or extrinsic compression). method: patients referred by endosonography with bulging of upper gastrointestinal tract were studied retrospectively. the size, location, consistency and presumptive diagnosis were recorded at time of endoscopy and endosonography. endosonography-guided fine-needle aspiration was proposed in case of uncertain diagnose to increase diagnostic sensitivity. results: one hundred seventy-six patients (93 women) and mean age 62.5 years (10-87). one hundred fifty-three had subepithelial tumor and 23 had extrinsic compression as a final diagnosis. endosonography had sensitivity, specificity and accuracy higher than those found by endoscopy for both diagnosis subepithelial tumor and extrinsic compression. endoscopy and endosonography showed poor concordance (k = 0.13) for subepithelial tumor diagnosis and unsuitable agreement for diagnosis in extrinsic compression (k = 0.01). the endosonography-guided fine-needle aspiration had sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 75%, 72.4%, 80.5%, 65.6% and 74%, respectively. conclusion: endoscopy has high sensitivity and low specificity for subepithelial tumor and both are low for the extrinsic compression. endoscopy is a good tool for diagnosis of the subepithelial tumors, but not to determine the cause of an extrinsic compression. the endosonography identifies the layer from which subepithelial tumor comes, obtain histological samples, and increasing the diagnostic accuracy.
