What this trial studies

This study evaluates the effectiveness of Transanal irrigation (TAI) in improving the quality of life and alleviating symptoms of Low Anterior Resection Syndrome (LARS) in rectal cancer survivors. Participants will be taught how to perform TAI through a novel online platform, with virtual nursing support provided throughout the process. This multicenter, randomized control trial will recruit patients from five academic hospitals in Ontario and Quebec, focusing on those who have undergone low anterior resection surgery and experience significant LARS symptoms. The study aims to determine the feasibility and acceptance of TAI among Canadian patients, as previous studies have shown positive outcomes in Europe.

Who should consider this trial

Good fit: Ideal candidates are rectal cancer survivors who have undergone low anterior resection surgery and have a LARS score greater than 20.

Not a fit: Patients with an ostomy, ongoing treatment, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the quality of life for rectal cancer survivors suffering from LARS.

How similar studies have performed: While TAI has shown positive results in European studies, this is the first large-scale randomized control trial in North America, making it a novel approach.
