Um novo método de avaliação do "tempo esofágico" com ultra-sonografia por abordagem externa

Abstract: OBJETIVO: Utilizar a ultra-sonografia como método de avaliação do "tempo esofágico" e sua capacidade de discriminação entre as substâncias não-sólidas ingeridas (água e iogurte). MATERIAIS E MÉTODOS: Foram estudados 22 adultos jovens, sem queixa gástrica e esofágica, de ambos os sexos. Foi utilizado transdutor de ultra-som de 3,5 MHz, convexo, em modo B, colocado na região epigástrica. O intervalo de tempo esofágico foi determinado utilizando-se um cronômetro que foi acionado no momento da movimentação da glot… Show more

“…Intermittent observation of the stomach fundus filled with barium is performed with radioscopy for detecting the contrast medium reflux from the stomach backwards up to the esophagus (10) . Currently, the comparative study of IEUS and UGIS has demonstrated that IEUS presents a higher sensitivity in the diagnosis of GER (9,17) and in the evaluation of the intraabdominal esophagus, with a reduction of the exposure to ionizing radiation for these patients (11,18) . However, the determination of reflux degree as well as the evaluation of the intrathoracic esophagus cannot be performed with this method (18,19) .…”

However, the determination of reflux degree as well as the evaluation of the intrathoracic esophagus cannot be performed with this method (18,19) . The determination of the GER degree could be done with IEUS, although not as specifically as the UGIS does, by means of a comparative study between these two techniques.…”

“…No references were found in the literature with regard to honey classification. Yogurt, on the other hand, was considered in the investigations as pasty (13)(14)(15)(16)(17)(18) , thin pasty (10,11) , thick/thickened liquid (10,19,20) , pasty liquid (10) , and thick pasty liquid (21) . Some professionals emphasized, in the food classification, that the five foods presented are not usually offered to patients in hospital diets.…”

“…The intra-abdominal esophagus could be easily reached and identified by ultrasonography, allowing the visualization of the water/yogurt passage . The ETT could be determined in both men and women, with the aid of a stopwatch started at the moment the deglutition of water or yogurt was initiated, until the substance passage was visualized through the intra-abdominal esophagus (10) . The sonographic evaluation of the thoracic esophagus by external approach is impaired by the access difficulty, both through the anterior and posterior mediastina because of the presence of air in the lungs and bone tissue in the dorsal spine through which sound waves cannot appropriately propagate (11) .…”
