STUDY OF THE IMMEDIATE AND COSMETIC RESULTS OF USING A NEW METHOD OF CLOSING A WOUND DEFECT IN THE SACROCOCCYGEAL REGION AFTER EXCISION OF A PILONIDAL SINUS

Rationale: Pilonidal sinus (PS), or the more common name in Russia, epithelial coccygeal duct, is an acquired disease in which there are fistulas on the skin of the intergluteal region. During mass examinations, PS occurs in 3–5% of healthy people with an incidence of 26 cases per 100 thousand. people with a predominance of male population. Cosmetic results of surgical treatment are not always satisfactory — 13–17% may develop hypertrophic scars, wound healing time can be up to 70 days and, accordingly, the period of temporary disability increases.
Objective:to evaluate the cosmetic effect of surgical treatment of pilonidal sinus, wound healing time and periods of temporary disability.
Methods:A prospective single-center randomized study (n = 100 patients) with PS without abscess (L05.9) was conducted at the State Budgetary Healthcare Institution Research Institute-KKB No. 1, Department of Purulent Surgery from January 2019 to January 2021. In the main group (n = 50), excision of the pilonidal sinus was performed with plastic closure of the wound defect of the sacrococcygeal region according to RU patent No. 2751821 dated July 19, 2021; in the control group (n = 50), excision of the PS was performed with suturing using the Bascom II method.
Results:When analyzing the results, the groups were homogeneous by gender, age, and BMI. There was no significant difference in wound healing time (p = 0.913). The period of temporary disability in the control group was shorter and amounted to 18 days (p<0.001). The cosmetic effect of the operation according to the POSAS scale after 1 and 6 months, both from the doctor and from the patient, was better expressed in the main group (p<0.001).
Conclusion: The developed method is simple in technical execution and reliable, which allows it to be used in routine practice and does not require special (plastic) training of the surgeon.
