Does the reason for sigmoid surgery change bowel function later?
NCT ID NCT04729283
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This study compares bowel function and quality of life in adults who had a sigmoidectomy, a surgery to remove the sigmoid colon, for either diverticulitis or sigmoid cancer. Researchers will measure incontinence using a standard score and track stool form with the Bristol stool chart. The goal is to see whether the underlying condition affects long-term outcomes after the same surgical procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sigmoidectomy, a surgical procedure to remove the sigmoid colon, performed by laparoscopy or open surgery, with reconnection of the bowel.
- What this could lead to
- If this study succeeds, it could clarify how bowel function and quality of life differ after sigmoidectomy for diverticulitis versus cancer, helping surgeons set realistic expectations and tailor follow-up care.
- What could go wrong
- This is an observational study with a modest number of participants, so results may not apply to all patients. Differences in outcomes could stem from the underlying disease rather than the surgery itself.
