Colonic motility is an essential component of normal colonic physiology and it controls essential bodily functions such as stool propulsion, storage, and expulsion. Disordered colonic motility may present with constipation or diarrhea as well as associated symptoms such as bloating, gas, pain, incontinence, and others. In order to assess colonic motor function, practitioners may use studies that either investigate transit time or that evaluate peristaltic activity. Transit time is the result of both the effectiveness of propulsive pressures and the physical characteristics of the stools. Its measurement allows one to quantify the extent and severity of the colonic dysfunction and permits the assessment of response to therapy. Various methods exist to investigate colon transit time and motility. In this review, we will focus on newer techniques for these investigations, including: scintigraphic transit studies, anorectal manometry, colonic manometry, and studies using a wireless motility capsule.
结肠动力是正常结肠生理的重要组成部分，它控制着诸如粪便推进、储存和排出等基本身体功能。结肠动力紊乱可能表现为便秘或腹泻以及相关症状，如腹胀、气体、疼痛、失禁等。为了评估结肠运动功能，医生可以使用研究来调查传输时间或评估蠕动活动。传输时间是推进压力有效性和粪便物理特征的结果。其测量可以量化结肠功能障碍的程度和严重程度，并允许评估对治疗的反应。存在多种方法来研究结肠传输时间和动力。在本综述中，我们将重点关注这些研究的新技术，包括：闪烁扫描传输研究、肛门直肠测压、结肠测压以及使用无线动力胶囊的研究。
