Technique to Reduce Wound Size: The Double-Opposing Purse-String and Horizontal Continuous Closure Algorithm.

Background: Surgical reconstruction of complex wounds requires considerable planning to ensure optimal patient outcomes. A conservative approach utilizing the lower tiers of the reconstructive ladder is preferred, especially in patients with comorbidities lending to a higher risk of poor wound healing. A simplified, low-risk solution with a double-opposing purse-string suture (PSS) and horizontal continuous closure technique may be particularly helpful in reducing the need for more complex techniques of wound reconstruction in select patient populations. Methods: A retrospective chart review was performed on all patients who underwent reconstruction with the double-opposing PSS technique (N = 57) by the senior author (B.J.W.) at the University of Louisville between 2019 and 2022. Results: A total of 46 patients and 57 wounds underwent the double-opposing PSS and horizontal continuous closure technique as directed by the algorithm. The average defect size before and after was 61 and 12 cm Conclusions: This approach to wound closure demonstrates usefulness in reducing the size of or need for skin grafts in complex wound patients, particularly in those with comorbidities. The majority of patients underwent successful closure of their complex defects in various areas (eg, face, extremities) with this technique. Residual defects requiring skin graft allowed for a smaller graft and, thereby, donor site. Ultimately, this technique reduces the risk of complex complications by simplifying and reducing wound size.
