Tratamiento quirúrgico de la enfermedad pilonidal sacrocoxígea. Experiencia de un centro en los últimos 4 años.

Aim: To evaluate long-term results in the surgical treatment of sacrococcygeal pilonidal disease (SPD) comparing the different surgical techniques used, complications, healing time and recurrence. Material and Method: Retrospective cross-sectional study. The files of the patients operated on for EPS between January 2017 and August 2021 were reviewed. For follow-up, information was obtained from the records of the periodic controls in our center; those who did not continue with these controls were contacted by telephone. Results: 309 cases were collected, with a mean follow-up of 15.6 months. The most used techniques for the chronic phase of EPS were marsupialization and Karydakis, achieving complete wound healing in 54.5 and 18.2 days, respectively. The presence of complications prolonged the healing time by 46.5 days in Karydakis, with minimal impact on marsupialization. The recurrence rate was lower in Karydakis and in the acute stage when unroofing and curettage were performed. Antibiotic prophylaxis did not increase the risk of postoperative complications. Discussion: The development of postoperative complications has a greater impact on the healing of the closed technique than in the open technique, the last one seems to be more tolerant in terms of healing in the presence of complications. Conclusion: The intervention with the Karydakis technique achieves healing of the surgical wound in less time than marsupialization, however, when complications develop, this time increases 3.5 times more. Recurrence was lower in Karydakis. In abscess weaning and curettage is recommended over the exclusive drainage. [ABSTRACT FROM AUTHOR]
