Ultrasonography is a non-invasive, relatively easy, validated and reproducible technique. We assessed the usefulness of functional ultrasonography to study disorders of gastro-oesophageal tract, gallbladder and pancreatic duct. Oesophagus Oesophagus and the gastro-oesophageal junction can be visualized in children up to 5 years old. Ultrasonography shows 100% sensitivity and 87.5% specificity compared to ambulatory pH-metry for gastro-oesophageal reflux disease diagnosis. Stomach Ultrasonography can be used to estimate whole gastric volume, antral area or diameters, antro-pyloric volume, transpyloric flow in fasting state and in response to test meal. Gallbladder Ultrasonography is reliable to estimate volume in fasting state and in response to test meal or exogenous stimulus. For both stomach and gallbladder, indications might include the study of healthy subjects and of pathophysiologically relevant conditions such as dysmotility-like dyspepsia, suspicion of delayed gastric emptying, diabetes mellitus, gallstone disease and effect of drugs either delaying or accelerating motility. Common bile duct Ultrasonography can be used to estimate interprandial and postprandial common bile duct diameter in patients with clinical suspicion of common bile duct obstruction in fasting state and in response to test meal or exogenous stimuli. Although functional ultrasonography is used mainly for research purposes, its simplicity makes it appealing for clinical use to assess gastrointestinal motility in health and disease.
超声检查是一种非侵入性、相对简便、经过验证且可重复的技术。我们评估了功能性超声检查在研究胃食管、胆囊和胰管疾病方面的实用性。食管 5岁以下儿童的食管和胃食管交界处可以可视化。与动态pH监测相比，超声检查对胃食管反流病诊断的敏感性为100%，特异性为87.5%。胃 超声检查可用于估计空腹状态下以及对试餐反应时的全胃容积、胃窦面积或直径、胃窦幽门容积、经幽门血流量。胆囊 超声检查在估计空腹状态下以及对试餐或外源性刺激反应时的胆囊容积方面是可靠的。对于胃和胆囊，适应证可能包括对健康受试者以及诸如运动障碍样消化不良、怀疑胃排空延迟、糖尿病、胆结石病以及药物对运动的延迟或加速作用等病理生理相关情况的研究。胆总管 对于临床怀疑在空腹状态下以及对试餐或外源性刺激反应时有胆总管梗阻的患者，超声检查可用于估计餐间和餐后胆总管直径。尽管功能性超声检查主要用于研究目的，但其简便性使其在评估健康和疾病状态下的胃肠动力方面具有临床应用吸引力。
