Can a chemical rinse speed healing of abdominal abscesses?
NCT ID NCT06906029
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial tests whether injecting a chemical sclerosant (povidone iodine or ethanol) into an abdominal abscess can reduce the time a drainage catheter is needed. About 60 adults with non-fistulous abscesses at least 3 cm in size will receive either standard drainage or drainage plus sclerotherapy. The study will measure pain and complication rates, and whether the abscess comes back within a week.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a chemical sclerosant (povidone iodine or ethanol) injected into the abscess cavity through a drainage catheter
- What this could lead to
- If it works, this could shorten the time patients need a drainage catheter and lower the chance of needing another procedure.
- What could go wrong
- This is an early-phase trial with only 60 patients, so results may not apply broadly. The sclerosant could cause pain or complications like infection or allergic reaction.
