- In a study comprising 100 patients referred to a surgical clinic with symptoms suggestive of gastro-oesophageal reflux disease the value of different diagnostic procedures was investigated. Positive acid perfusion and 24-h pH tests were the commonest findings. Forty-nine per cent showed a normal oesophageal mucosa or diffuse oesophagitis at endoscopy. The severity of heartburn and regurgitation did not differ between patients with normal oesophageal mucosa and oesophagitis of various severities. The severity of macroscopic oesophagitis was significantly correlated to the total reflux time, the presence of reflux or a hiatal hernia at radiology, an open cardia or reflux at endoscopy, pressure transmission or reflux and low lower oesophageal sphincter pressure at manometry. Gastric hypersecretion was found in 66% of the patients. Gastric acid secretion was not correlated to the severity of oesophagitis or to the findings at 24-h pH test. In patients with severe oesophagitis the sensitivity for radiologic, manometric, and endoscopic signs of incompetence of the gastro-oesophageal junction was 94%.

- The aim was to study the exposure time of acid during 24 h at two different oesophageal levels in 15 healthy subjects and its relation to other kinds of oesophageal findings. Five centimetres above the lower oesophageal sphincter the total reflux time was 0.2% (0-1.3%), and at the 15-cm level it was 0.1% (0-0.7%). A standardized compression test during manometry and radiologic examination showed that no subject had reflux. Hiatus hernia was provoked at the radiologic examination in four subjects, one of whom also had a widened hiatus. At endoscopy, one subject had a hiatus hernia and slightly granulated oesophageal mucosa. Biopsy specimens showed slight basal cell hyperplasia in one case. Bleeding in the dermal papillae or a few intraepithelial leukocytes were seen in eight cases, findings that might be due to endoscopic trauma. Without any history of gastrointestinal disorders, gastrooesophageal reflux was minimal under standardized conditions, although hiatus hernia and mild changes in biopsy specimens could be seen.
