Could a simple drink fix a complication of cancer surgery?
NCT ID NCT06820320
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tested whether taking iohexol by mouth can treat chylous ascites, a leak of lymphatic fluid that can happen after abdominal or pelvic cancer surgery. The study enrolled 42 patients who developed this condition after surgery. The goal was to see if oral iohexol could stop the fluid buildup quickly and safely, potentially offering a simpler alternative to more invasive treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- iohexol (a contrast agent taken by mouth)
- What this could lead to
- If it works, this could offer a simple, non-surgical treatment for chylous ascites after cancer surgery, reducing the need for more invasive procedures.
- What could go wrong
- This is a small, early-phase trial with only 42 participants. The results may not apply to all patients, and the safety and effectiveness need confirmation in larger studies.
