Motility disorders of the gastrointestinal (GI) tract have traditionally been diagnosed by excluding mechanical small-bowel obstruction. In order to diagnose GI motility disorders in a positive fashion, small-bowel manometry was performed on 15 patients who were referred to the authors with intestinal motility disorders. Intestinal manometry was performed after first positioning a 200-cm multilumen tube into the small intestine. Ports located at 10-cm intervals were perfused with sterile water and connected to pressure transducers to record intraluminal pressures with a multichannel chart recorder. This low compliance water perfusion manometry system allowed examination of both fasting and postprandial motility. Intestinal manometry was able to assist in the diagnosis of two patients that had true mechanical small-bowel obstruction. One patient had a stenosis of the gastrojejunostomy and three patients had a functional gastric outlet obstruction secondary to a motility disorder in the Roux limb. One patient had a functional obstruction from a reversed jejunal loop and eight patients were identified as having intestinal pseudo-obstruction. We found intestinal manometry was a helpful adjunct in the diagnosis of GI motility disorders.
胃肠道（GI）动力障碍传统上是通过排除机械性小肠梗阻来诊断的。为了以肯定的方式诊断胃肠动力障碍，对15例因肠道动力障碍转诊至作者处的患者进行了小肠测压。在将一根200厘米长的多腔管置入小肠后进行肠道测压。每隔10厘米的端口用无菌水灌注，并连接到压力传感器，用多通道图表记录仪记录腔内压力。这种低顺应性水灌注测压系统能够检查空腹和餐后的动力情况。肠道测压有助于诊断2例真正的机械性小肠梗阻患者。1例患者有胃空肠吻合口狭窄，3例患者因Roux袢动力障碍继发功能性胃出口梗阻。1例患者因空肠袢翻转出现功能性梗阻，8例患者被确诊为肠道假性梗阻。我们发现肠道测压是诊断胃肠动力障碍的有用辅助手段。
