Should both hernias be fixed at once? new trial aims to settle the debate
NCT ID NCT07289490
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial will study 2,200 adults with bilateral inguinal hernias (one painful, one not). Half will have both hernias repaired at once, the other half only the painful side. The goal is to compare chronic pain, complications, and the need for future surgery. The study uses Sweden's national hernia registry to track outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgical procedure (laparo-endoscopic hernia repair)
- What this could lead to
- If it works, this could help doctors decide whether to repair an asymptomatic hernia at the same time as a symptomatic one, potentially reducing unnecessary surgery and chronic pain.
- What could go wrong
- This is a large trial but it hasn't started yet. The results may not apply to all hernia types or surgical techniques. There is always a risk of complications from surgery, such as pain or recurrence.
