Pelvic colonic pressures were recorded before, during, as well as after a meal in patients with non-specific diarrhoea (12) or constipation (14), who were selected according to strict clinical criteria of bowel habit. In the basal state diarrhoeal patients as a group had significantly less colonic activity than constipated patients, but the overlap was considerable. During the meal colonic activity was strikingly increased in diarrhoea, but returned to basal levels immediately after the meal; no such response was observed in constipation. It is suggested that this brief segmental response of the pelvic diarrhoeal colon may be inadequate to prevent entry of faeces into the rectum and the desire to defaecate, following a meal.
根据严格的排便习惯临床标准，选取了12名非特异性腹泻患者和14名便秘患者，记录他们在进餐前、进餐期间以及进餐后的盆腔结肠压力。在基础状态下，腹泻患者组的结肠活动明显少于便秘患者，但两者有相当大的重叠。进餐期间，腹泻患者的结肠活动显著增加，但进餐后立即恢复到基础水平；便秘患者未观察到这种反应。有人认为，餐后盆腔腹泻结肠的这种短暂节段性反应可能不足以防止粪便进入直肠和产生便意。
