What we have learned about colonic motility: normal and disturbed

Area of Science:

• Gastroenterology and Physiology
• Neurogastroenterology

Background:

• Colonic motor and sensory dysfunction are prevalent in both pediatric and adult populations.
• These disorders present significant hurdles in diagnosis and treatment.
• Understanding the underlying pathophysiology is crucial for developing effective interventions.

Purpose of the Study:

• To critically review recent scientific literature on colonic motor and sensory function disorders.
• To assess the current state of knowledge regarding the pathophysiology, diagnosis, and treatment of these conditions.

Main Methods:

• Literature review of recent studies on colonic motility and sensory function.
• Analysis of ultrastructural, molecular, and electrophysiological findings.
• Evaluation of clinical diagnostic and therapeutic approaches.

Main Results:

• Significant progress has been achieved in elucidating the normal functions of colonic muscles, nerves, and interstitial cells.
• Abnormalities in these cells, particularly interstitial cells of Cajal, are implicated in various diseases.
• Clinical testing of colonic function remains difficult due to technical and physiological variability.
• Therapeutic advancements for disturbed colonic motility have been limited, with ongoing exploration of new agents and innovative approaches like neural stimulation and cell therapy.

Conclusions:

• Basic science has advanced understanding of colonic dysmotility pathophysiology.
• Clinical diagnostics and therapeutics for colonic motor and sensory disorders have not kept pace with basic science discoveries.
