The reliability of ultrasonography (US) was investigated in the diagnosis of gastroesophageal reflux in the pediatric patient. Therefore, specificity and sensitivity of US were compared with those of a 24-hour pH monitoring. A hundred and twenty-nine patients were examined; their age ranged 38 days to 14 years (56 were under and 73 over 2 years old). Since these patients presented with gastroesophageal symptoms, they underwent both pH monitoring and US. The results of the two methods were in agreement in 79.8% of the cases. Notably, in the age group ranging 0 to 2 years, US exhibited greater sensitivity (87% vs. 78.8%) and slightly lower specificity (76.5% vs. 81.1%) than in the age group ranging 2 to 14 years. The greater sensitivity in the 0-2 age group can be explained by physiological factors (which are typical of the first months of life) as well as by technical factors. Therefore, in infants, US should be combined with pH monitoring to identify the cases which are unquestionably pathological. The high specificity in the children over 2 years of age could justify the use of US alone in this group of patients for both diagnosis and follow-up, while pH monitoring might be used only in the most severe and/or complicated cases. The results suggest that, in the two age groups considered, abdominal US can be used not only as the diagnostic method of choice in the study of gastroesophageal reflux, but also as an extremely useful tool during follow-up when therapeutic monitoring is also needed. |
