What this trial studies

This clinical trial investigates the effectiveness and safety of fecal microbiota transplantation (FMT) as a treatment for patients with irritable bowel syndrome (IBS). The study involves infusing a fecal suspension from healthy donors into the patients' colons to restore a balanced gut microbiome. Participants will receive FMT at least twice and will be monitored for a minimum of six months using questionnaires to assess their symptoms and overall gut health. The trial is conducted at Guangzhou First People's Hospital, focusing on a standardized approach to microbiota isolation and transplantation.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients suffering from irritable bowel syndrome.

How similar studies have gone: While fecal microbiota transplantation has shown success in treating recurrent Clostridium difficile infections, its application for irritable bowel syndrome is less established, making this study a novel exploration.
