Duplex-Doppler was used to visualize intestinal peristalsis in 30 patients with intestinal distension. The series included 12 patients with acute mechanical obstruction, 13 with long-standing mechanical obstruction, and five with paralytic ileus. The Duplex-Doppler recordings showed several patterns characterized by different degrees of intensity and frequency of the signals according to the type of obstruction, its duration, and the site of Doppler sampling relative to the obstructed segment. Duplex-Doppler evaluation provided both qualitative and quantitative data about intestinal peristalsis, allowing differentiation between mechanical and paralytic ileus. The visualization of intestinal segments having different degrees of peristaltic activity proved useful in localizing the site of mechanical obstruction.
采用双功多普勒超声观察30例肠梗阻患者的肠道蠕动情况。该组患者包括12例急性机械性肠梗阻、13例慢性机械性肠梗阻和5例麻痹性肠梗阻。双功多普勒记录显示了几种模式，这些模式根据梗阻类型、持续时间以及多普勒取样部位与梗阻段的相对位置，表现出不同程度的信号强度和频率。双功多普勒评估提供了关于肠道蠕动的定性和定量数据，有助于鉴别机械性肠梗阻和麻痹性肠梗阻。观察具有不同蠕动活动程度的肠段，对定位机械性肠梗阻部位很有帮助。
