Outcome of Limberg Flap Reconstruction in the Management of Pilonidal Sinus Disease: A Retrospective Study

Introduction: Pilonidal Sinus Disease (PSD) is a tract or cavity commonly seen in the sacrococcygeal region, usually containing a tuft of hair. It is mostly observed in drivers who have excessive hair in the natal cleft region. Although several surgical procedures have been described for the management of PSD, none have been universally accepted as the gold standard. Limberg flap reconstruction, following wide excision, offers a tension-free repair using a well-vascularised flap. This technique flattens the natal cleft, avoiding a midline scar and reducing the chance of recurrence. Aim: The aim of this study was to determine the outcomes of Limberg flap reconstruction in sacrococcygeal PSD. Materials and Methods: A retrospective descriptive study was conducted in the Department of General Surgery at M S Ramaiah Medical College, Bangalore, Karnataka, India. The study duration was six years, from January 2011 to January 2017. The study included a total of 40 patients aged between 15-70 years, with Tezel type III sacrococcygeal Pilonidal Disease (PND), who underwent the Limberg flap procedure. Data was collected and analysed from January to June 2021. Outcome measures such as duration of hospital stay, time required to return to work, and procedure-related complications associated with procedure were analysed and entered into an Excel sheet. Results: The mean age of the study participants was 18.02±6.87 years. Out of the 40 patients, 4 (10%) developed complications. Superficial wound infection was observed in 1 (2.5%) patient, which healed within two weeks. Minimal flap necrosis was observed in 2 (5%) patients, who underwent debridement and dressings on an outpatient basis. The wounds healed within three to four weeks. Recurrence was reported in 1 (2.5%) patient. The mean time to return to work was 18.7±4.88 days. Conclusion: Limberg flap reconstruction for sacrococcygeal PSD is a simple technique with a lower complication rate, faster return to normal activity, and a low recurrence rate.
