Gastrointestinal motility testing

Gastrointestinal motility and the effects on luminal contents that are brought about by it can be studied in several ways. In clinical practice, manometry remains one of the most important investigational techniques, in particular for oesophageal and anorectal disorders. Radiographic examination of bolus transit through the gastrointestinal tract also continues to be a valuable tool. Scintigraphy still is the gold standard for assessment of gastric emptying, but 13C breath tests are an alternative. Many other techniques are used mainly in the context of scientific research but some of these may become incorporated in the diagnostic armamentarium.
