Solid‐state <i>vs</i> water‐perfused catheters to measure colonic high‐amplitude propagating contractions

Abstract

SS catheters are more sensitive in recording HAPCs in children with defecation disorders compared with the more traditional WP assembly. There is a difference in measurements of amplitude between the two systems. Solid-state catheters offer potential advantages over WP catheters in children, being portable, safer to use, and may provide data over a more prolonged period.
