The aim of this study was to determine whether ultrasonography of the pancreas can be used as an auxiliary tool in the diagnosis of adult patients with type 1 and type 2 diabetes mellitus. The size and echogenicity of the pancreas were evaluated by ultrasound in 81 diabetic patients: 20 type 1 and 61 type 2 (53 obese and 8 non-obese). Obese type 2 diabetic patients showed different results from patients in the other groups, with significantly larger pancreas area and anteroposterior body diameter. The pancreas was more frequently hyperechogenic in obese type 2 diabetic patients than in type 1 diabetic patients. We concluded that ultrasonography of the pancreas may be used as an auxiliary tool for the diagnosis of type 1 and type 2 diabetic patients, although this method showed to be less efficient in non-obese patients.

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.
