What's the Gips Procedure?

A pilonidal cyst is a fluid-filled sac under the skin in the lower back, near the crease of the buttocks. Some aren't visible, while others can look like a small pit or dimple in the skin.

Sometimes, a pilonidal (pie-luh-NIE-dul) cyst can become infected. One way that doctors can treat an infected cyst is with the Gips procedure.
