对结肠动力研究的方法众多,归纳起来有两种类型:1.个别结肠节段或肌肉单位的研究;2.结肠或全胃肠转运时间的研究。前者提供有关大肠是如何工作的信息,而后者是测定摄入的食物通过大肠所需的时间。本文对有些主要的研究方法进行介绍和讨论。节段和肌肉研究放射显影术该技术是识别结肠收缩和进行分类最有用的方法,但有接触大量放射线的 There are two different types of colonic motility studies: 1. studies of individual colon segments or muscle units; 2. studies of colon or total gastrointestinal transit time. The former provides information on how the large intestine works, while the latter measures the time it takes for the food ingested to pass through the large intestine. This article describes and discusses some of the major research methods. Segmental and Muscular Radiographic Studies This technique is the most useful method of identifying colon contractions and classifications, but there is exposure to large amounts of radiation
