Abstract
BACKGROUND: Peristomal pyoderma gangrenosum (PPG) is an unusual but potentially devastating condition that is difficult to diagnose and manage. METHODS: This was a single centre, retrospective review of a prospectively collected database. Included were consecutive patients referred to a stoma therapy clinic at a single institution between 2005 and 2016. Main outcomes of interest were management strategies and outcome of patients with PPG including time to healing and recurrence. RESULTS: Of 1295 consecutive patients who underwent stoma formation, 12 patients with PPG were identified. The mean age at the time of diagnosis of PPG was 43.5 years (range 19-72 years). Five cases (41.7%) were associated with Crohn's disease and five cases (41.7%) with ulcerative colitis. The median duration of days between stoma formation and PPG diagnosis was 101.5 days (mean duration was 670 days (range 14-2641 days)). Nearly all patients (91.7%) were referred to a dermatologist. Majority (66.7%) were managed in an outpatient setting. For those requiring inpatient management, the mean length of stay was 13.5 days (range 3-31 days). Five patients had a biopsy and seven patients were diagnosed with PPG by dermatologist without biopsy. A range of oral and topical steroids, steroid injections, dressings, anti-inflammatories, antibiotics, tacrolimus and analgesia was used in the management of PPG. All patients achieved complete healing of PPG, with only one patient developing a recurrence of PPG. The mean duration of time to achieve complete healing of PPG was 282 days (range 28-1751 days). DISCUSSION: Medical management of PPG was effective with complete healing and low recurrence. The average duration to complete healing of PPG was approximately 9 months.
