OBJECTIVE: To assess the success of treatment methods at reducing recurrence, the most important problem in pilonidal sinus disease (PSD), along with factors affecting the occurrence of PSD and posttreatment recurrence.


METHODS: The researchers retrospectively analyzed files of patients treated for PSD between 2003 and 2018. Three study groups were created: G1, G2, and G3. G1 included all PSDs with recurrence, and a comparable number of cases without recurrence were selected randomly for the G2 group. The control group, G3, included healthy individuals without PSD. In all groups, the following were recorded: body mass index, skin color and oiliness, family history of PSD, hair overgrowth, smoking habit, time spent sitting per day, and number of baths per week. The following were additionally recorded for G1 and G2: treatment methods, follow-up periods, pretreatment abscess(es), and time of onset of complaints before treatment. The number of recurrences and the period between last treatment and recurrence were also recorded for G1.


RESULTS: G1 comprised 234 patients; G2, 247 patients; and G3, 128 healthy individuals. The significant factors causing recurrence included body mass index, family history, bathing habits, hair overgrowth, skin color and oiliness, time spent sitting per day, smoking habit, abscess(es), and duration of symptom(s) (P < .05). Limberg flap repair was the most successful treatment method. Sixty-three (27%), 135 (58%), and 185 (79%) recurrences occurred in the first 6 months, in the first year, and in the first 2 years, respectively.


CONCLUSIONS: The researchers recommend Limberg flap repair for treatment. It is possible to reduce recurrence by taking preventable factors into consideration.
