摘要:

目的 比较胃食管反流显像和唾液吸入显像在诊断儿童肺吸入方面的价值。方法 140名儿童患者[(年龄在3周~18岁,平均年龄(3.4±2.1)岁,其中男孩61例,女孩79例]同时行胃食管反流显像和肺吸入显像。回顾性分析并比较这两种显像的诊断结果。结果 胃食管反流显像显示1.4%(2/140)的患儿有肺吸入胃食管反流物;而唾液吸入显像显示22.1%(31/140)的患儿有肺吸入唾液,且胃食管反流显像阳性的2名患儿的唾液吸入显像也呈阳性表现。结论 在诊断肺吸入方面,唾液吸入显像的价值大于胃食管反流显像。因此如欲明确是否有肺吸入存在,则应首先行唾液吸入显像。

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
