Crystallized phenol treatment vs excision and primary closure in pilonidal sinus disease: A randomized clinical trial in adolescent patients.

Abstract

INTRODUCTION\nPilonidal sinus is a chronic inflammatory disease seen in the intergluteal sulcus. A wide variety of treatment modalities have been described for the management of this disease, however optimal therapy remains controversial. The study aims to compare phenol treatment, a minimally invasive method used in the treatment of pilonidal sinus disease, with the commonly practiced surgical methods of excision and primary closure in the adolescent age group.\n\n\nPATIENTS AND METHODS\nAdolescent patients who presented with pilonidal sinus disease between January 2018 and December 2018 were randomized into 2 groups as phenol treatment and surgical treatment (after obtaining consent for the study). Early complications and recurrence rates after 24 months of follow-up were the two main endpoints of the study.\n\n\nRESULTS\nA total of 100 patients (phenol group n\xa0=\xa050, surgery group n\xa0=\xa050) were included in the study. Both groups were similar in terms of age, gender, and BMI. The mean duration of the procedure was 12.4\xa0±\xa02.84\xa0min in the phenol group and 42.3\xa0±\xa07.22\xa0min in the surgery group (p\xa0=\xa00.00). There was no difference in postoperative complications between the groups (p\xa0=\xa00.22). After 24 months of follow-up, recurrence was found in 8% (n\xa0=\xa04) of the cases in the phenol group and 10% (n\xa0=\xa05) of the cases in the surgery group (p\xa0=\xa00.5).\n\n\nCONCLUSION\nIn our study, phenol treatment and excision/primary closure methods for pilonidal sinus disease have similar complication and recurrence rates. However, phenol treatment seems to be the method of choice in the adolescent age group as it has the advantage of being a minimally invasive method and it does not affect subsequent surgical treatments.\n\n\nLEVEL OF EVIDENCE\nLevel II treatment study.
