Treatment options for patients with pilonidal sinus disease: PITSTOP, a mixed-methods evaluation.

Background: There is no consensus on optimal management of pilonidal disease. Surgical practice is varied, and existing literature is mainly single-centre cohort studies of varied disease severity, interventions and outcome assessments.

Objectives: A prospective cohort study to determine: • disease severity and intervention relationship • most valued outcomes and treatment preference by patients • recommendations for policy and future research.

Patient preferences for pilonidal sinus treatments: a discrete choice experiment survey.

Background: A range of treatments are available for pilonidal sinus disease (PSD), each of which has a different risk/benefit profile. The aim of this study was to collect patient views on which interventions they would rather avoid and which outcomes they most value for PSD.

Method: We conducted an online survey using the discrete choice experiment (DCE) method.
