High‐resolution impedance manometry characterizes the functional role of distal colonic motility in gas transit

The colonic motor patterns associated with gas transit are poorly understood. This study describes the application of high-resolution impedance manometry (HRiM) in the human colon in vivo to characterize distal colonic motility and gas transit; (a) after a meal and (b) after intraluminal gas insufflation into the sigmoid colon.HRiM recordings were performed in 19 healthy volunteers, with sensors positioned from the distal descending colon to the...
