New stoma technique aims to ease bowel troubles after rectal cancer surgery
NCT ID NCT06149741
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new type of temporary colostomy (a surgical opening in the belly) for people having rectal cancer surgery. The goal was to see if it could reduce bowel problems and kidney injury compared to the usual stoma. Only 16 patients were enrolled before the study was stopped early, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Defunctioning left-sided loop colostomy (surgical procedure)
- What this could lead to
- If successful, this new stoma type could reduce bowel dysfunction and dehydration after rectal cancer surgery, improving quality of life.
- What could go wrong
- This is a very small pilot study (16 patients) that was terminated early, so results may be limited. The procedure also carries risks like bowel ischemia.

Inclusion Criteria: * Age ≥18 years * Capacity for informed consent * Planned defunctioning stoma * Planned mesorectal excision with anastomosis for rectal cancer Exclusion Criteria: * Manifest atherosclerotic disease (peripheral vascular disease, previous myocardial infarction, angina, etc) * Previous oncological colonic resection * Defunctioning stoma in situ * Intraoperative event leading to bowel resection and subsequent inability to bring out left-sided colostomy without tension on the anastomosis * Intraoperative circumstances as judged by the operating surgeon leading to unacceptable risks due to loop colostomy placement (abdominal wall size, short mesentery, other preconditions)
