[The radiological diagnosis of peptic ulcer of the oesophagus (author's transl)].

In the two years 1974--1976, the radiographic diagnosis of peptic ulcer of the oesophagus was made in 14 patients. All these patients showed oesphagogastric reflux at fluoroscopy, 13 had an axial hiatus hernia. The ulcer lay at the oesophagogastric junction in 13 patients, in one patient it was located 5 cm. above the cardia. Endoscopy was performed in 11 patients and confirmed the X-ray diagnosis. The authors believe the best technique for this purpose to be "hypotonic oesophogography" and that this is essential for the differential diagnosis between benign and malignant ulcers.
