Discriminating movements of liquid and gas in the rabbit colon with impedance manometry

Background High‐resolution impedance manometry is a technique that is well established in esophageal motility studies for relating motor patterns to bolus flow. The use of this technique in the colon has not been established. Methods In isolated segments of rabbit proximal colon, we recorded motor patterns and the movement of liquid or gas boluses with a high‐resolution impedance manometry catheter. These detected movements were compared to...
