Motility in the sigmoid and rectal areas was studied before, during, and after a 900-cal meal in 11 healthy subjects. A Honeywell esophageal pressure transducer with three transducers was used for the recording. A 900-cal meal significantly stimulated colonic motility during eating. The frequency of contractions was responsible for this increase while the amplitude of the contractions remained the same. Colonic motility returned to fasting levels immediately after the meal. Recording periods of 30 min were not capable of distinguishing individual variations in colonic motility because of long periods of inactivity but were adequate when groups of subjects were compared. Body position did not affect colonic motility. These studies suggest that a meal stimulates sigmoid and rectal motility in healthy subjects, but only during the consumption of the meal.
在11名健康受试者中，研究了900卡路里餐食进食前、进食期间和进食后乙状结肠和直肠区域的蠕动情况。使用带有三个传感器的霍尼韦尔食管压力传感器进行记录。900卡路里餐食在进食期间显著刺激结肠蠕动。收缩频率导致了这种增加，而收缩幅度保持不变。进餐后结肠蠕动立即恢复到空腹水平。由于存在长时间的静止期，30分钟的记录期无法区分结肠蠕动的个体差异，但在比较受试者组时是足够的。身体姿势不影响结肠蠕动。这些研究表明，餐食会刺激健康受试者的乙状结肠和直肠蠕动，但仅在进食餐食期间。
