title: [Importance of the "knocking" symptom in detecting peptic ulcer in flight personnel].
abstract: In order to diagnose peptic ulcer, the "percussion" symptom in the right hypochondrium at the inhalation level was used in the flying personnel, aged 19-45. Peptic ulcer, specifically duodenal ulcer in the acute stage was diagnosed in 75 persons and in the remission stage-in 69 persons. The control group consisted of 29 healthy subjects. The diagnostic importance of this symptom was shown. It was found in 29.3, 14.5 and 3.4% of cases, respectively. In 8 subjects who concealed complaints or showed an atypical development of the disease there was a sharp response to "percussion" that suggested peptic ulcer which was confirmed by X-ray studies.
