Novel clues for ultrasonographic diagnosis of reflux in pregnant women: a pilot study.

ABSTRACT

The aim of the present study was to define some novel radiological clues that may aid in the ultrasonographic diagnosis of gastroesophageal reflux in pregnant women. A total of 84 pregnant women, consisting of 42 reflux patients and 42 controls were included in the study. Reflux and control groups were compared in terms of age and our novel ultrasonographic landmarks related to oesophageal structure. While the two groups did not differ in terms of age, they were significantly different from each other with respect to single layer, single wall oesophageal thickness; double layer, double wall oesophageal thickness; oesophageal hiatal diameter; perioesophageal fat pad thickness; hypoechogenic single wall muscularis mucosa and lamina propria thickness. Owing to our newly defined radiological clues, ultrasonography may have a 'greater than expected' role in the diagnosis of gastroesophageal reflux in pregnant women. However, further studies must be performed to document the actual diagnostic potential of these radiological tips.
