The two primary symptoms of colonic motility dysfunction are altered bowel habits (constipation, diarrhea) and intermittent abdominal cramping. Additional symptoms include straining, urgency, feeling of incomplete evacuation, passage of mucus, bloating or feeling of abdominal distension, and postprandial exacerbation of symptoms.

What does our large intestine do? The primary functions of the large intestine (colon) are to store food residues and to absorb water. Between what we drink and what is secreted into the stomach and intestine to help with food absorption, about 5 gallons of fluid is dumped into the large intestine every day.

What’s the key to keeping digestion moving from esophagus to colon? Motility, or the contraction of the muscles that mix and move what’s inside your gastrointestinal tract. Digestion is a balance of contraction and relaxation. When something inhibits either, motility disorders occur.

Measurement of colon transit time is the most basic and primary tool in evaluating disorders of colonic motility. In particular, it is helpful in pathologic diagnosis and for planning management in patients with constipation. Several techniques for measuring colon transit time currently exist.

In the colon, unlike the stomach and small bowel, there is no interdigestive cyclic motor activity. Colonic motility is characterized by the presence of irregular periods of quiescence alternating with nonpropagating and propagating contractions.

Colonic Motility: From Bench Side to Bedside. Motility refers to spontaneous motion/movement, be it of a single cell moving through tissue or medium, or material moving inside hollow organs, e.g., the gastrointestinal tract, cardiovascular system, bladder, and uterus. In all cases, the cell or organ itself generates the force for motion.

Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function.

Upper gastrointestinal motility disorders involve the esophagus, stomach or upper part of the small intestine. Lower gastrointestinal motility disorders involve the small intestine, colon (or large intestine) and rectum.
