Abstract Objective: To determine the volume of the gallbladder after fasting and postprandial in preterm neonates using a high-frequency transducer, and to discuss the fasting filling state and contraction rate of the gallbladder in preterm neonates. Methods: Terason t3000 color Doppler ultrasound diagnostic apparatus was used to examine the gallbladder after fasting and postprandial and to calculate the volume and contraction rate of the gallbladder. Results: ①The average volume of the gallbladder after fasting in 67 preterm neonates was 0.086 mL(0.028, 0.186), which was significantly smaller than that in 42 term neonates which was 0.292 mL(0.102, 0.671), P<0.05. ②Poor contraction in preterm neonates(16/46, 34.8%) was significantly higher than that in term neonates(5/36, 13.9%), χ2=4.628，P<0.05. Conclusion: The gallbladder volume in preterm neonates after fasting was smaller than that in term neonates, and was combined with poor contraction in some cases, suggesting that the size and function of the gallbladder in preterm neonates was not yet well developed, and needed to be carefully distinguished from biliary atresia.
