The aim was to study fasting and postprandial rectal tone in patients with cauda equina injury. Electromechanical barostat measurement of rectal tone was made in 13 healthy volunteers and in five patients during a 10 min recording, while fasting and for 1 h after a 1000 kCal intake. A prompt decrease of rectal volume was observed in all control subjects and patients. The delay between the end of the meal and the onset of the rectal response was always less than 3 min in the five patients as well as in the control group. The rapidity of the rectal response to feeding observed in our five patients suggests that the rectal response was mediated via a neural or neurohumoral pathway despite severe injury of the sacral parasympathetic supply.
