La pH-metria conbinata esofagea e gastrica di 3 ore versus pH-metria combinata di 24 ore

Short-term esophageal and gastric combined pH-monitoring was performed in a group of patients with “typical” symptoms of gastroesophageal refiux. A-nother group of patients, admitted to longterm combined ’esophageal and gastric pH monitoring, made up the control group The-'correlations syrnptorns/pH-tést and pHtest/esophagitis demonstrated that the short-term esophageal and gastric combined pH-monitoring provides diagnostic data comparable to those of long-term esophagea1 and gastric combined pH-monitoring
