Decision regret following surgical management of pilonidal disease.

Aim: Surgical decision making in the context of pilonidal disease (PD) can be challenging. Current evidence for the management of PD is inadequate and optimum treatment is not clear. This paper reports on patient experience of shared decision making (SDM) and decision regret following surgical management of PD.

Method: The Pilonidal Trial. Studying the Treatment Options (PITSTOP) study (ISRCTN95551898) is a prospective cohort study of patients with PD treated between May 2019 and March 2022. This subanalysis reports the results of quantitative data capture between baseline and 6 months post-procedure. Baseline data consisted of patient and disease characteristics, surgical procedure and impression of SDM. Post-procedure data consisted of operative outcomes and decision regret. Multiple linear regression analysis was used to analyse the relationship between clinical outcomes and decision regret.

Results: Overall, 677 patients were included, and follow-up data to 6 months were available for 476 (71%). Most (59.5%) patients underwent major excisional surgery; 45.1% of patients experienced a postoperative complication. Participant impression of SDM was positive, with a median CollaboRATE mean-score response of 3 (interquartile range: 3-4). Of the patients who underwent a 'leave open' approach, 20.6% were dissatisfied or very dissatisfied with their treatment. Postoperative complications (β = 3.21, 95% CI: -12.75 to 7.25, p < 0.001) and disease recurrence (β = 11.5, 95% CI: -10.6 to 9.4, p < 0.001) were both associated with higher rates of decision regret.

Conclusion: The clinical outcomes, postoperative complications and recurrence, were associated with higher levels of decision regret. Surgeons treating patients with PD should practice SDM and ensure that patient priorities inform treatment approach.
