Wellcome- High resolution manometry

High resolution, invasive, optical manometry that detects pressure changes inside the bowel.

(A) A condensed manometric recording of the colon of a single subject over a 2-h period (1 h before and after a meal). The white line in the middle of the trace shows where the subject started the meal. Note the rapid increase in number of pressure events after the meal. (B) It is an enlargement of the red hatched box in A. Numerous retrograde cyclic propagating motor patterns are visible; they clearly comprise majority of the increased contractile activity induced by the meal. (C) It shows the same data as seen in B, but shown as a traditional low-resolution trace (lines spaced at 7 cm). All propagation is lost and these data would have been labeled as ‘non-propagating’.
