[The colonosphincterometrogram (CSMG). An original method of simultaneous study of the motility of the left colon and of the anal sphincters].
Colonsphinctorometrography (CSMG) is a new, original method for the simultaneous investigation of the motility of the descending colon, sigmoid colon, rectosigmoid junction, rectum, and internal and external anal sphincters. A 60 cm open-ended tip sound with an external diameter of 10 mm is used. Three 3 cm long stimulating balloons are located at points 15 cm, 30 cm, and 50 cm along its length. A basal recording is taken for about 15 min with the patient absolutely at rest. The balloons are then inflated to measure the kinetic responses of colon and anal sphincters to stimuli of different volume. In addition to offering a pressure recording for the left colon and internal sphincter, the method also provides an EMG for the external sphincter and a pneumogram.
