title: Gastroesophageal scintigraphy following gastrectomy: comparison to endoscopy and esophageal biopsy.
abstract: We evaluated the relationship between gastroesophageal scintigraphy, endoscopy, and biopsy in 48 gastrectomy patients (33 with reflux and 15 without reflux symptoms). Endoscopic esophagitis was demonstrated in 78.8% of the patients with reflux symptoms, histological esophagitis was found in 72.2% of them, and scintigraphic reflux was found in 81.8%. Either endoscopic or histological esophagitis was recognized in 93.7% of the patients with reflux symptoms, while either scintigraphic reflux or endoscopic esophagitis was demonstrated in 97.0%. Scintigraphic reflux was significantly more common in patients with histological esophagitis than in those without it (92.9% vs. 40%, p < 0.01). In addition, it was found in 74.2% of patients with and 64.7% of patients without endoscopic esophagitis. The reflux index tended to increase as the grades of esophagitis increased; there was an approximate relationship between the two parameters. Our study suggested that scintigraphy reflects histological esophagitis rather than endoscopic esophagitis, and that there was an approximate relationship between the reflux index and the endoscopic grade of esophagitis. In addition, performance of scintigraphy and endoscopy combined with esophageal biopsy increased the diagnostic yield in gastrectomy patients with reflux symptoms.
