| Popis: | Until the advent of the ultrasonographic investigation of the gastroesophageal re. ux (GER) proposed by Naik and Moore in 1984 and many others after Wright et al. (1988), imaging of the esophago-gastric junction (EGJ) required some invasive methods, such as the conventional irradiating barium upper gastrointestinal tract opaci. cation or endoscopic investigation that required sedation. It has been clearly demonstrated that the upper gastrointestinal conventional barium exploration has a poor sensitivity against reflux disease (43%), and, for this reason, many authors suggest starting with an endoscopic investigation or 24-h pH monitoring. Barium examination can sometimes still be reserved for some patients under 1 year of age, for those undergoing surgery and, finally, for those with negative pH monitoring but who are strongly suspected of suffering from a pathological reflux (Al-Khawari et al. 2002). Ultrasound has a better sensitivity than barium studies in detecting small hernia. In addition, functional data can also be acquired by this technique. |
