Anal fistula repair can be performed using laser technology or traditional open surgery, depending on the severity and location of the fistula. In laser fistula treatment (FiLaC), a laser probe is inserted into the fistula tract to destroy the infected tissue and seal it. This method is minimally invasive, preserves sphincter function, and ensures faster healing. Open fistula surgery involves excising the fistula tract or placing a seton to allow gradual healing. Both procedures are performed under spinal or general anesthesia. Recovery time varies, with laser treatment allowing faster return to normal activities. Potential complications include infection, recurrence, or incontinence in complex cases. Post-operative care involves sitz baths, a fiber-rich diet, and proper wound hygiene. Laser fistula repair is preferred for its reduced pain and quicker healing, while open surgery remains effective for complex fistulas.
