Ovarian cancer prevention: a simple Add-On during gallbladder surgery?
NCT ID NCT07625137
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether removing the fallopian tubes at the same time as gallbladder surgery is safe and practical. Ovarian cancer often starts in the fallopian tubes, so removing them may prevent it. The trial will enroll 240 women aged 35 and older to see if the extra procedure is feasible and doesn't cause complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bilateral salpingectomy (removal of both fallopian tubes)
- What this could lead to
- If successful, this could offer a simple way to prevent ovarian cancer during common gallbladder surgery, reducing cancer risk without extra major procedures.
- What could go wrong
- This is an early feasibility study with only 240 participants. It may show the procedure is not safe or practical, and results may not apply to all patients.
