Summary

This study tests whether removing the fallopian tubes during planned gallbladder removal surgery is safe for women aged 45 and older. The goal is to see if this extra step can help prevent ovarian cancer without causing more complications. About 300 women will take part, with half getting the added procedure and half having standard gallbladder surgery alone.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: opportunistic salpingectomy (removal of fallopian tubes)
What this could lead to: If successful, this could offer a safe way to reduce ovarian cancer risk during routine gallbladder surgery.
What could go wrong: This is a small, early-stage trial focused on safety, not cancer prevention. It may not show a clear benefit or apply to all women.
