Comparing two surgical techniques for rectal cancer treatment

Official title: Postoperative and Long-term Outcomes of Transanal Tran-section and Single-stapled Anastomosis (TTSS) in Rectal Can-cer Patients: a Multicentric International IDEAL Stage 2b Prospective Parallel Cohort Study

Run by Istituto Clinico Humanitas · NCT06314646 · Data updated 2026-11-12

This study is testing a new surgical technique for rectal cancer to see if it can lead to fewer complications compared to the traditional method for patients having surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults diagnosed with rectal cancer who are scheduled for elective rectal resection with either TTSS or double-stapled techniques.

Probably not a fit

Patients requiring abdominoperineal resection or those with concurrent invasive pelvic malignant tumors may not benefit from this study.

What this trial studies

This study evaluates the Transanal Transection and Single-Stapled anastomosis (TTSS) technique as an alternative to the traditional double-stapled anastomosis in patients undergoing surgery for low rectal cancer. It aims to compare postoperative and functional outcomes between these two surgical approaches. By expanding data collection to multiple countries, the study seeks to provide robust prospective data to confirm previous findings that suggested TTSS may reduce anastomotic leaks. The research involves adult patients scheduled for elective rectal resection with Total Mesorectal Excision (TME).

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced complications for rectal cancer patients.

How similar studies have gone: Previous studies have suggested the TTSS technique may be advantageous, but this study aims to provide more comprehensive prospective data to validate those findings.
