Abstract Objectives To evaluate whether fetal pancreatic echogenicity and its measurements are associated with gestational diabetes mellitus (GDM) and perinatal outcomes. Methods A prospective cohort study was conducted with 150 pregnant women with a singleton pregnancy. The study included pregnant women between 30 and 41 weeks with or without GDM. Fetal pancreatic circumference was measured using the free-hand tracking function. The echogenicity of the fetal pancreas was compared with the echogenicity of the liver and bone (ribs, spine) and classified as Grades 1, 2 and 3. The relationship between maternal characteristics and perinatal outcomes with fetal pancreas measurements and echogenicity was evaluated. Results Pregnant women with 75 GDM and 75 without GDM were included in the study. Mean fetal pancreas circumference measurements were significantly higher in pregnant women with GDM than in those without GDM (p=0.001). Hyperechogenic (Grade 3) fetal pancreas was significantly higher in pregnant women with GDM than in pregnant women without GDM, and there was a positive correlation between pancreatic echogenicity and HbA1c levels in pregnant women with GDM (r=0.631, p<0.01). There was a significant relationship between pancreatic echogenicity, measurements and adverse neonatal outcomes in pregnant women with GDM, and pancreas measurements were significantly higher in pregnant women with cesarean delivery. Conclusions Fetal pancreatic echogenicity and measurements in pregnant women with GDM can give an idea about glucose regulation and adverse perinatal outcomes.
