The technique of two successive abdominal roentgenograms at a five minute interval is proposed as a new method of evaluating small bowel activity in the presence of postoperative intestinal distention. One hundred and forty-four cases of postoperative small bowel distention were studied with this technique and correlated with the clinical evaluation of the bowel sounds and with the development of a variety of postoperative complications. Correlation with the bowel sounds was fairly good, except in the presence of a clinical description of hypoactive sounds. Reduced activity on the successive roentgenograms after the third postoperative day was frequently associated with postoperative complications, while persistent small bowel distention in the presence of significant roentgen activity usually indicated mechanical small bowel obstruction. This method for determination of small bowel activity thus appears to be useful in evaluating postoperative problems.
建议采用每隔五分钟连续进行两次腹部X线检查的技术，作为评估术后肠扩张时小肠活动的一种新方法。用该技术对144例术后小肠扩张病例进行了研究，并与肠鸣音的临床评估以及各种术后并发症的发生情况进行了关联分析。与肠鸣音的相关性相当好，除非有肠鸣音减弱的临床描述。术后第三天后连续X线检查显示活动度降低常与术后并发症相关，而在X线活动明显时持续存在小肠扩张通常提示机械性小肠梗阻。因此，这种测定小肠活动的方法似乎有助于评估术后问题。
