A Comparative Study on flap necrosis following Karydakis Flap Reconstruction and Z-Plasty in Patients with Sacrococcygeal Pilonidal Disease – Our experience

Aim: The purpose of this study was to evaluate patients with sacrococcygeal pilonidal sinus disease(SPSD) who underwent the Karydakis procedure and Z plasty at our centre concerning theperioperative findings, late postoperative results and recurrence. Patients and Methods: A total of30 patients presenting with SPSD at our centre underwent Karydakis flap repair and Z plasty fromMay 2019 to June 2021. These patients were then followed up and evaluated concerning operativetime, drain use, hospital stay, suture removal, complications, and recurrence. The adipocutaneousflap of Karydakis was devised to shift the natal cleft, while Z-plasty involves a fasciocutaneous flap.Results: The mean operative time was 60 min with a median hospital stay of 4 days. Drains wereremoved at a median of 5 days and sutures at a median of 15 days. The duration of hospitalisationfor the Karydakis procedure was found significantly lesser than that for Z-plasty Patients who werefollowed up for a median of 12 months. The overall complications were more in Z-plasty. Flapnecrosis developed in 30 % of the cases in the Z-plasty group, comparable to no recurrence seen inthe Karydakis procedure. Co
