We present a method for estimating volumes of abdominal organs using 3-D ultrasonography. In vitro validation experiments demonstrated excellent agreement between estimated and true volumes. In vivo estimations after ingestion of 500 ml meat soup showed greater antral filling and poorer emptying of the gallbladder in patients with functional dyspepsia (FD) than in healthy controls. Abnormal antral filling was associated with dyspeptic symptoms. The relationship between motility and transpyloric movements of luminal contents after ingestion of 500 ml meat soup was studied in healthy subjects by duplex technique. Accurate timing of antegrade and retrograde flow were recorded using bidirectional velocity curves. Mid-cycle and end-cycle reflux were often observed; end-cycle reflux was more frequent in conjunction with coordinated than with uncoordinated antroduodenal contractions. The peristaltic closure of the pylorus was normally preceded by a short gush of duodenogastric reflux.
我们提出了一种使用三维超声检查来估计腹部器官体积的方法。体外验证实验表明，估计体积与真实体积之间具有极佳的一致性。摄入500毫升肉汤后进行的体内估计显示，与健康对照组相比，功能性消化不良（FD）患者的胃窦充盈度更高，胆囊排空更差。胃窦充盈异常与消化不良症状相关。通过双功技术在健康受试者中研究了摄入500毫升肉汤后管腔内内容物的运动与经幽门运动之间的关系。使用双向速度曲线记录顺行和逆行血流的准确时间。经常观察到周期中期和末期反流；与不协调的胃十二指肠收缩相比，在协调的胃十二指肠收缩时末期反流更频繁。幽门的蠕动关闭通常先有一阵短暂的十二指肠-胃反流。
