Sacrococcygeal Pilonidal Sinus Disease: A Decade‐In‐Review of Patient‐Reported Outcome Measures

Year: 2025

Type: article

Abstract: BACKGROUND: Sacrococcygeal pilonidal sinus disease (SPD) is a chronic inflammatory condition that can significantly impact quality of life. While recurrence and surgical site infection (SSI) rates are well documented, less is known about how different surgical techniques affect patient-reported outcome measures (PROMs). METHODS: This study employed mixed methods, including standardised mail questionnaires and telephone interviews (May-September 2020), to conduct a multi-centre retrospective decade follow-up review of definitive SPD surgery participants from Western Australia. Six surgical technique groups were analysed: Karydakis flap (KF), modified Karydakis flap (MKF), Limberg flap (LF), modified Limberg flap (MLF), other flap techniques (OFT) and secondary intention healing techniques (SIT). PROMs assessed included body image, cosmesis, confidence, functional recovery and overall satisfaction-secondary outcomes examined recurrence, SSI and other complications. RESULTS: A total of 136 patients met the inclusion criteria. MLF and OFT achieved the fastest functional recovery, with median return-to-work times of 14 and 21 days, respectively, compared to 60 days for SIT (p = 0.007). MKF and LF achieved the highest body image and cosmetic satisfaction scores (medians of 20 and 19), whereas SIT and OFT scored the lowest. MKF yielded the highest overall satisfaction (100%). SIT was associated with the highest recurrence rate (52.2%) and SSI rates (30.4%), while MLF and MKF combined had low recurrence rates with favourable PROMs. CONCLUSION: Flap-based techniques, particularly the MKF and MLF, offer an optimal balance of functional recovery, cosmetic outcomes and low recurrence rates. Incorporating PROMs into SPD surgical planning can better align treatment with patient priorities and the underlying pathophysiology of the disease.
