Abstract

Abstract:

Objective The purpose of this study is to determine the accuracy of gastroesophageal reflux scintigraphy and salivagram in the diagnosis pediatric aspiration.Methods Totally 140 pediatric patients (age between 3 weeks and 18 years, average age: 3.4 years; 61 males, 79 females) received gastroesophageal reflux scintigraphy and salivagram simultaneously. The two scans were retrospectively analyzed and compared. Results In 1.4% of the patients (2 of 140), gastroesophageal reflux scintigraphy displayed pulmonary aspiration. In 22.1% of the patients (31 of 140), salivagram displayed pulmonary aspiration. Two patients with positive gastroesophageal reflux scintigraphy also showed positive salivagram.Conclusion Salivagram is better than gastroesophageal reflux scintigraphy in the diagnosis of pediatric aspiration. Therefore, salivagram should be performed in order to exclude pulmonary aspiration. A further investigation with larger patient number is necessary to assess the validity of our findings.

Key words: pulmonary aspiration, gastroesophageal reflux scintigraphy, salivagram
