Investigation of non-cardiac chest pain using intraesophageal balloon test and acid perfusion]

ABSTRACT

Mechano--and chemo--sensitivity were studied in 20 normal control patients and 73 patients suffering from pirosis, chest pain or both symptoms. Upper endoscopy, balloon and acid perfussion tests were performed. Balloon was inflated up to 15 ml. and deflated, in 2 cm. steps from 38 to 22 cm. from S.D.A. The number of patients with response, volume of balloon distension that evoked symptoms, place and irradiation of pain or discomfort were registered and plotted on 13 frontal and 10 dorsal zones. The total number of areas involved in pain irradiation was considered as [quot ]number of responses[quot ]. Nine levels were stimulated. Acid perfusion and clearance tests were performed at the same session. Test positivity was accepted when some test evoked spontaneous patients symptoms. RESULTS: When 9 levels were stimulated, balloon reproduced symptoms in 77.5
