What this trial studies

This observational study investigates the effectiveness of total or subtotal colectomy in improving defecation function and quality of life for patients suffering from slow transit constipation (STC). It aims to follow patients for five years to assess both short- and long-term outcomes after surgical intervention. The study addresses a significant gap in the literature regarding the long-term effects of surgical treatments for STC, which affects a notable percentage of the population. By focusing on patients who have not responded to conservative treatments, the study seeks to provide valuable insights into surgical efficacy.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with functional constipation who have severe symptoms and have not responded to conservative treatments for over a year.

Not a fit: Patients with megacolon, intestinal organic lesions, or those with mental health issues such as depression or anxiety may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options and enhanced quality of life for patients with severe slow transit constipation.

How similar studies have performed: While surgical interventions for STC have been performed historically, this study aims to provide new insights into long-term outcomes, making it a novel approach in this area.
