First experiences with ultrasonic diagnosis using gastroenterologic endoscopy in Hungary

: The authors were the first to gain experiences with gastroenterological endoscopic ultrasonography (EUS) in Hungary. Their examinations included the study of the esophageal wall and its environment as well as that of the stomach wall and the neighbouring organs. The construction of the instrument, the technique of the method and the indication for EUS are described on the basis of the authors' experiences and the literary data. They were the first to demonstrate perigastric effusion with EUS. On the basis of the observations it is stated that EUS is more reliable than other methods for the determination of the patency of varices following sclerotherapy. Thus this technique may improve the control of the efficacy of sclerotherapy in patients with portal hypertension. The authors wish to support their observation with prospective examination series carried out with high number of patients.
