Comparison of curettage plus platelet-rich plasma gel and curettage plus phenol application in treatment of pilonidal sinus disease: A randomized trial.

Sevinç B, Damburaci N, Karahan O.

Dis Colon Rectum 2022; 65:735-741.

Two hundred patients had their pilonidal sinus curetted and then treated with either plasma gel or phenol crystals. Healing was more likely after a single application of plasma – 96 versus 53 per cent; it was also quicker (6 versus 10 days, P<0.001) and recurrence after one year was lower (4 versus 12 per cent).

Comment: Extraordinary result that needs confirmation to ensure it is generalisable.
