Summary

This study tests a minimally invasive laser technique called SiLaC for treating pilonidal sinus, a painful condition near the tailbone. Forty adults will receive the laser procedure, which aims to destroy the sinus tract and speed up healing. Researchers will track how quickly patients return to normal activities and monitor for complications or recurrence.

What this could mean

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

Active substance
Laser (1470-nm diode laser radial fiber)
What this could lead to
If successful, this laser technique could offer a faster, less painful recovery for people with pilonidal sinus, reducing the need for more invasive surgery.
What could go wrong
This is a small, early-stage study with only 40 participants and no comparison group. The procedure may not work for everyone, and recurrence or complications are still possible.
