Background: In 2018, Dandin et al. described a new method called the De-epithelialization technique (DT) for treating patients with pilonidal sinus disease. In our study, we compared DT to the conventional Limberg flap (LF) procedure. Patients and Methods: The LF and DT groups each had 20 patients. Patients from the DT group underwent surgery under local anesthesia and were discharged on the same day. Patients from the LF group were operated under subarachnoid block and managed as indoor patients. All 40 patients were analyzed for patients age, sex, weight, body mass index, operative time, and early complications. Results: The mean age of all patients was 28 years, with a standard deviation of 5.6 years. Moreover, the mean body mass index was 25.5, with a standard deviation of 3.45. The mean operative time was significantly shorter for the DT group (45.65 minutes) than for the L.F group (58.5 minutes; p < .001). The DT group had a significantly higher incidence of wound dehiscence (8/20, 40%) than the LF group did (1/20, 5%; p = .020). Conclusion: Our study determined that the LF method has a lower complication rate compared to DT, though the latter provides shorter operative time and hospital stay.
