Whole natal cleft excision and flap : an alternative surgical method in extensive sacrococcygeal pilonidal sinus disease.

BACKGROUND

Pilonidal sinus disease (PSD) is a benign disease caused by hair follicles in sacrococcygeal -region. Despite the use of different methods in treatment, there is no consensus reached for treatment modalities. In this study, we used a whole natal cleft excision and flap (WNCEF) method to remove the natal cleft in cases of extensive sacrococcygeal PSD.

METHODS

243 patients with PSD were evaluated retrospectively. 47 patients with extensive sacrococcygeal PSD were included in the study. In these patients, the natal cleft was excised by using a whole natal cleft excision and flap -(WNCEF) method which was performed by an incision to include all the natal cleft (Kite incision) and the remaining defect was closed with a single fasciocutaneous flap by sliding along the midline intergluteal sulcus.

RESULTS

The mean age of patients was 25.7 years (17-43). The average hospital stay of patients was 2.7 days (2-4), mean operative time was 59 min (35-80), mean duration of drain removal was 2.7 days (2-4), mean postoperative follow-up was 16.4 months (3-24) and mean BMI was 26.9 (22-30). Flap edema occured in one patient (2.1%), seroma in three patients (6.3%) and surgical site infection requiring re-use of antibiotics were observed in two patients (4.2%). Flap -necrosis and failure did not occur in our patients. No recurrence was observed in any patient during an average follow-up of 16 months.

CONCLUSIONS

In sacrococcygeal PSD treatment, removal of the natal cleft with Kite incision by WNCEF method and shifting of the midline completely are thought to be an effective method that can reduce recurrence.
