Chronic severe constipation. Prospective motility studies in 25 consecutive patients

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Physiology

Background:

• Severe constipation affects a significant patient population.
• Accurate diagnosis of underlying causes is crucial for effective management.
• Distinguishing between functional disorders and primary motility issues remains a challenge.

Purpose of the Study:

• To investigate the gastrointestinal and anal sphincter motility patterns in patients with severe constipation.
• To identify distinct subgroups of motility disorders contributing to severe constipation.
• To differentiate these disorders from irritable bowel syndrome.

Main Methods:

• Recruitment of 25 consecutive patients diagnosed with severe constipation.
• Assessment of gastrointestinal motility including anal sphincter function, colonic, esophageal, and gastric emptying.
• Diagnostic criteria included impaired sphincter relaxation, generalized motor disorders, and rectosigmoid motor response abnormalities.

Main Results:

• 68% of patients exhibited abnormal motility patterns: isolated anal sphincter dysfunction (20%), generalized gastrointestinal motility disorder (24%), and rectosigmoid dysfunction (24%).
• No significant correlation was found between symptom duration, laxative use, or historical features and specific motility patterns.
• The remaining patients had unrecognized primary disorders or irritable bowel syndrome.

Conclusions:

• A substantial proportion of severe constipation cases are linked to serious, potentially treatable, bowel function disorders.
• These findings suggest that severe constipation warrants thorough motility investigation beyond typical functional disorder assessments.
• Early identification of specific motility dysfunctions can guide targeted therapeutic interventions.
