摘　　要：目的:探讨应用B超测定近端胃舒张功能的可行性,并对操作条件进行标准化。用该法研究功能性消化不良(FD)患者近端胃舒张功能的改变。方法:选择健康对照者20名(对照组),FD患者31名(FD患者组),采用实时B超测定进食液体试餐(500mL,711.28kJ)后近端胃容积,同时对受试者试餐前后上腹部症状进行评分。结果:试餐后40min前各时间点FD患者组近端胃容积明显小于对照组(P<0.05)。48.4%的FD患者舒张期至少有一个时间点的近端胃容积异常。FD患者组试餐后较对照组诱发更明显的症状(P<0.01),77.4%的FD患者餐后出现症状诱发加重。结论:FD患者近端胃舒张功能受损。B超法可应用于与近端胃舒张功能相关的胃肠动力疾病研究和临床实践。Objective To investigate the validity and the optimal procedures of uhrasonography in measuring volumes of the proximal stomach and to observe its postprandial accommodation in patients with functional dyspepsia （FD）. Methods The volumes of the proximal stomach were measured by uhrasonography in 31 FD patients and 20 healthy cases after drinking 500 mL test-meal that was standarized in temperature and calorie density. Upper abdominal discomforts and air pockets in the gastric fundus were recorded and assessed at the same time. Results The postprandial proximal volumes in FD patients were smaller than those in healthy cases in most moments （ P 〈 0.05 at 0, 5, 10, 15, 20 and 30 min, respectively ）. 48.4% of FD patients come forth at least one time or more abnormal change of proximal gastric accommodation. After the test-meal, 77, 4% experienced wornsening abnormality of proximal gastric accommodation（ P 〈 0. 01）. Conclusions The patients with functional dyspepsia have impaired proximal gastric accommodation, especially after the test-meal, which can be detected and measured by B-type ultrasonography. This is a good practical and noninvasive method in assessing motility diseases that are related with changes in proximal accommodation.
