Traditional surgical approaches such as wide excision or flap techniques may result in prolonged healing times, relevant postoperative pain, and recurrence rates up to 20-30%.\n\nThe SiLaC (Sinus Laser-Assisted Closure) technique is a minimally invasive procedure that uses a 1470-nm diode laser fiber to ablate the sinus epithelium and induce concentric contraction of the tract. International studies have reported promising results with faster recovery, minimal wound care, and low morbidity.\n\nThis prospective single-center cohort study aims to evaluate the clinical outcomes and perceived recovery time of adult patients treated with the SiLaC® technique at Hospital Universitario La Paz (Madrid, Spain). The main outcome is the total recovery time perceived by patients after surgery. Secondary outcomes include postoperative complications, recurrence rate, pain intensity, need for wound care, and patient satisfaction. Data will be collected from medical records and structured follow-up interviews.",[46,47,48,49,50],"Pilonidal Sinus Disorder","Pilonidal Cyst Without Abscess","Pilonidal Sinus","Pilonidal Cysts","Pilonidal Sinus Treatment",[52,53,9,54,55,56,57],"Pilondal sinus","Pilonidal Cyst","laser-assisted closure","minimal invasive surgery","coloproctology","postoperative recovery","NOT_YET_RECRUITING","2025-12-02",{"date":61,"type":62},"2025-12-09","ACTUAL",{"date":64,"type":41},"2025-12-01",{"date":66,"type":41},"2026-08-31",{"name":5,"class":6}]
