Dufourmentel Flap Surgery in Pilonidal Sinus Disease: Our Late Results

We aimed to present the results of the Dufourmentel flap surgery technique and the parameter findings evaluated in the patients. Material and Methods: Between August 2015 and August 2020, out of 149 patients who had undergone Dufourmentel flap surgery performed by a single surgeon, 23 were excluded from the control and follow-up and 126 cases were evaluated retrospective. Results: The mean follow-up period was 30(range 18-42) months. Of the patients, 111(88,1%) were male, 15 females (11.90%) and the mean age was 22,6 (range 15-73) years. A family history was noted in 38(30,2%) of the patients. Various pre-operative interventions had been carried out on 23(18,3%) patients. There were 30(23,8%) patients with a single sinus opening on the midline and 96(76,2%) cases with multiple sinus openings located to the right or left of the midline. Intermittent discharge was detected in 88(69,8%), pain in 18(14,3%) and swelling in 20(15,9%) patients. There were 31(24,6%) patients operated on with acute (0-6 months) disease, 95(75,4%) with chronic disease and 15(12%) with recurrent disease. Surgical complications included 2(1,6%) hematomas, 2(1,6%) wound infections and 2(1,6%) wound dehiscence. Repeat surgery was reported in 6(4,7%) cases. The recurrence rate was (4/111)3,6% only in patients undergoing primary surgery. Conclusion: The Dufourmentel flap technique is one of the successful method applied in the surgical treatment of chronic pilonidal sinus. This method is reliable in terms of complications and is a good option because of its low recurrence rate.
