Abstract

BACKGROUND:

It is difficult to study human colonic motility under physiologic conditions. An important limitation associated with prolonged colonic recording is the failure of the sensors to resist normal expulsive forces.

METHOD:

In this article we describe a method of endoscopically positioning a manometric catheter by using clips in conjunction with a solid-state catheter. With the use of a rotatable clip-fixing device loaded on to a colonoscope, the manometric catheter was clipped to the colonic mucosa.

RESULTS:

Recordings for up to 120 hours were obtained from 6 subjects without apparent migration of the catheter assembly. No complications were noted, the catheter does not interfere with defecation, and defecation does not result in its expulsion.

CONCLUSION:

The current technique will allow reliable ambulatory measurements over prolonged periods of time in relatively comfortable and unrestrained subjects. This technique should increase our understanding of normal and abnormal colonic motility.
