Abstract:
Background: Endoscopic pilonidal sinus treatment (EPSiT) is a novel, minimally invasive surgical technique that has shown promise in the treatment of pilonidal sinus disease. Despite the apparent benefits and call for increased use, widespread uptake has been slow. This study aims to gather and understand expert international opinions on EPSiT and develop recommendations for its application in the surgical community.

Methods: Expert international panellists were identified and recruited to participate. A three-round modified Delphi consensus consisting of 43 questions regarding the application of EPSiT was posed. A combination of a five-point Likert scale, binary 'yes/no' scale and multiple-choice questions was used. The consensus threshold was set at 70% agreement. When consensus was not achieved or further insight was required, statement questions were posed. The study has been performed in accordance with ACcurate COnsensus Reporting Document (ACCORD) explanation and elaboration guidelines.

Results: Twenty experts from six countries participated in all rounds, with a 100% response rate. Our experts agreed on 28 statements including: the absence of absolute contraindications to EPSiT; administering intravenous induction antibiotics routinely but not post-operative oral antibiotics; recommending laser epilation; offering re-EPSiT to the informed patient after first and second procedure failures; and that EPSiT should be incorporated into surgical training programmes.

Conclusions: This is the first study to provide an international expert consensus on the specific application of EPSiT in primary and recurrent adult and paediatric patients with pilonidal sinus disease. The findings of this study contribute to the development of protocols for EPSiT in pilonidal sinus disease management, addressing key areas of consensus and controversy and promoting procedure uptake.
