effect of platelet rich plasma (prp) on healing time in patients following pilonidal sinus surgery

Conditions: Pilonidal Disease; Pilonidal Sinus

Summary: our study was planned as a prospective controlled randomized study. the study was started after the ethics committee approval received from dışkapı yıldırım beyazıt training and research hospital. (23.08.2021 118/01). two groups of patients were planned in parallel. in the treatment of pilonidal sinus disease, in patients operated on with the fistulotomy and curettage technique, one group was followed up with classical dressing, while the other group was followed up with prp (platelet-rich-plasma) and classical dressing. wound infection, hematoma, length of hospital stay, recurrence, pain in the first postoperative week, and time to complete epithelialization of the wound (in days) were evaluated between the two groups.

Eligibility criteria:
inclusion criteria: * patients diagnosed with pilonidal sinus disease in our hospital between november 2021 and november 2022 exclusion criteria: * patients under 18 years of age * acute pilonidal abcess * recurrent disease * anemic patients (hg \< 10 mg/dl) * thrombocytopenic patients (plt˂10⁶/ml) * patients with a history of radiotherapy-chemotherapy * diabetes mellitus * patients using steroids
