Partial primary closure in sacrococcygeal pilonidal sinus: Modified with suture technique

The primary purpose of pilonidal sinus treatment is to minimize complications, accelerate wound healing, and minimize recurrence. However, invasive and minimally invasive methods are being developed to reduce these problems. Early and late postoperative complications remain significant problems in pilonidal surgery. This study aimed to contribute to this issue in surgery by comparing the results of the Karydakis flap (KF) technique and those of the partial primary closure (PPC) technique, to which we applied suture modification.A total of 96 patients diagnosed with pilonidal sinus disease (PSD) were randomly assigned to two groups. Apply the partial primary closure in 46 patients and the Karydakis technique in 50.In comparison to the Karydakis technique, the partial primary closure (PPC) group's hospitalization stay was shorter, although the difference was not significant. Healing time was also longer in uncomplicated cases (p = 0.200 and 0.064, respectively). Abscesses and hematomas were not observed with partial primary closure, but the total complication rate was similar to that of the Karydakis technique. Surgical site infections were often seen in the PPC group (21.7% vs. 10%). In contrast, healing time for complicated cases was found to be significantly shorter in the PPC technique (p < 0.05).Postoperative abscess, hematoma, and seroma are the most common causes of total wound dehiscence, and delay in wound healing in off-midline techniques. We recommend the PPC technique with suture modification as an alternative to off-midline techniques in clean and chronically infected cases, other than cellulitis, abscess, and purulent discharge cases. However, we primarily recommend off-midline techniques in clean or asymptomatic cases.
