Summary

This study compares two minimally invasive treatments for pilonidal sinus disease: phenol injection and laser ablation. Researchers will track complications, hospital stay, and recovery time in 64 adults with uncomplicated pilonidal sinus. The goal is to find which method is safer and gets people back to daily life faster.

What this could mean

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

Active substance
phenol (sclerosing agent) and laser ablation (thermal energy)
What this could lead to
If successful, this could show which minimally invasive treatment is more effective for pilonidal sinus disease, helping patients recover faster with fewer complications.
What could go wrong
This is a small, early-stage observational study with only 64 participants, so results may not apply to everyone. Both treatments have risks like infection or incomplete healing.
