Less pressure, less pain? trial tests gentler gas levels for appendix surgery
NCT ID NCT07727499
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This trial compares two standard gas pressures used during laparoscopic appendectomy — 10 mmHg versus 15 mmHg — to see which leads to less pain and faster recovery. About 150 adults with uncomplicated appendicitis will be randomly assigned to one pressure level. Researchers will measure pain scores, surgery time, hospital stay length, and how quickly bowel function returns.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- laparoscopic appendectomy with either 10 mmHg or 15 mmHg pneumoperitoneum (gas pressure in the abdomen)
- What this could lead to
- If lower pressure works as well, it could mean less pain and faster recovery after appendix removal.
- What could go wrong
- Lower pressure might make surgery more difficult or increase complications. This is a single-center trial with 150 participants, so results may not apply broadly.
