A new method for wound defect closure after pilonidal sinus excision

AIM: to evaluate the efficacy of original method for pilonidal sinus (PS) treatment. PATIENTS AND METHODS: a randomized study included 100 patients with PS in the chronic stage at the State Budgetary Healthcare Institution Research Institute-KKB No. 1, Department of Purulent Surgery from January 2021 to January 2023. In the main group, excision of the pilonidal sinus was performed with plastic closure of the wound defect of the sacrococcygeal region according to RU patent No. 2751821 from 07/19/21. The control group included patients with Bascom II (cleft lift). There were no significant differences in age (p = 0.355), BMI (p = 0.467), gender distribution (p = 1.0), recurrence rate (p = 0,204). RESULTS: the operation time in the main group was longer (p < 0.001), which is associated with a surgical technique. Post-op stay (p = 0.027), the morbidity (p = 0,028) in the main group was significantly lower. The complications rate reduced to 4%, and the recurrence rate to 2%. It was possible to avoid re-operations. CONCLUSION: the original method for wound closure after PS excision is simple and reliable.
