Background: One of the most important surgical issues in the treatment of pilonidal sinus disease is recurrence. Aim of the work: The aim of this study is to compare two surgical techniques (rhomboid flap and semiclosure method) for treatment of recurrent pilonidal sinus. Patients & Methods: This randomized clinical trial was conducted in Zagazig University Hospitals between the period of Aug 2018 to Feb 2019 on 12 patients with recurrent pilonidal sinus, divided randomly into 2 groups: Group A 6 patients managed by semiclosure method and Group B 6 patients operated with rhomboid flap method. Results: There was a significant difference regarding pain duration, time of comfort sit, total time of healing and time of return to work between the two groups for the favor of group B which was markedly short in patients of group B. according to post-operative complication regarding delayed wound healing and wound infection had no significant difference between group A and group B. Regarding post-operative recurrence, follow up of both groups done during postoperative care and at time of 2nd, 3rd, 4th and 6th post-operative months. Only one case of group B had recurrence with no recurrent cases reported during the 6 post-operative months in group A .
Conclusions: Patient of group A shows decreased pain duration, time need for comfortable sit and early return to work. There no significant difference between the 2 groups in post-operative complications. Rhomboid flap repair is an advantageous and effective modality than semiclosure method in treatment of sacrococcygeal disease
