OBJECTIVE: To utilize intra-abdominal esophagus ultrasonography to evaluate esophageal transit time for water and yogurt in orthostatic position, and to evaluate the influence of gender and body mass index. MATERIALS AND METHODS: The present study included 89 young adults [40 women (mean age, 20.13 ± 1.62 years) and 49 men (mean age, 20.43 ± 2.17 years)] who did not show upper gastrointestinal tract disorder. Esophageal transit time was measured with the patient in orthostatic position during water and yogurt swallowing. RESULTS: Esophageal transit time for women and men was, respectively, 5.84 ± 1.60 seconds versus 6.66 ± 1.68 seconds with water, and 9.12 ± 1.96 seconds versus 9.28 ± 1.70 seconds with yogurt. No difference between genders was observed in spite of the lower body mass index in women. CONCLUSION: Data regarding esophageal transit time for liquid (water) and pasty (yogurt) food swallowed by young adults in the orthostatic position did not demonstrate any difference between genders even in women with lower body mass index as compared with men.
