Motility in the sigmoid, rectosigmoid, and rectum was studied before, during, and after a 900-kcal meal in 18 healthy elderly and 18 healthy young adults. Three intraluminal pressure transducers spaced 5 cm apart were used for the recording. No differences existed in the percentage activities and the surface areas under the contraction curves (SA) for the corresponding measurements during fasting, during eating, and after consumption of a meal in the elderly and young adults (P greater than 0.1). A 900-kcal meal significantly increased percentage activity and SA in all three recording areas in both the elderly and young adults (P less than 0.02). Percentage activity and SA returned to fasting levels immediately after consumption of the meal. Percentage activity and SA were highest 15 cm above the anal verge in both elderly and young adults. These findings suggest that age and gender do not affect sigmoidal, rectosigmoidal, and rectal motility.
对18名健康老年人和18名健康年轻人在摄入一顿900千卡的餐食之前、期间和之后，研究了乙状结肠、直肠乙状结肠和直肠的蠕动情况。使用三个间隔5厘米的腔内压力传感器进行记录。在老年人和年轻人禁食期间、进食期间和用餐后进行的相应测量中，收缩曲线下的活动百分比和表面积（SA）没有差异（P大于0.1）。一顿900千卡的餐食显著增加了老年人和年轻人所有三个记录区域的活动百分比和SA（P小于0.02）。用餐后，活动百分比和SA立即恢复到禁食水平。在老年人和年轻人中，活动百分比和SA在肛门边缘上方15厘米处最高。这些发现表明，年龄和性别不会影响乙状结肠、直肠乙状结肠和直肠的蠕动。
