Assessment, diagnosis and treatment of peristomal skin lesions by remote imaging: An expert validation study.

BACKGROUND: Prevention and treatment of peristomal skin problems should be a priority for nurses caring for ostomates, even when the assessment of lesions must be done remotely. OBJECTIVE: To measure the level of agreement on assessment, diagnosis and care indications for peristomal skin lesions using remote imaging among nurses in Spain. DESIGN: Prospective observational multicentre study to assess the diagnostic validity and inter- and intraobserver agreement between nurses in peristomal skin lesions. Data were collected between March and October 2019. SETTINGS AND PARTICIPANTS: The research sample consisted of a group of 39 nurses with expertise in the care of ostomates. METHODS: A panel of experts established a list of 24 common signs/findings, 15 diagnostic options and 35 treatment approaches for peristomal skin lesions. Three expert stoma therapy nurses compiled the clinical cases, which they described thoroughly and documented with photographs. The 39 participating nurses evaluated the cases in two rounds to measure inter and intraobserver agreement. RESULTS: A high or very high level of agreement (κ > 0.61) was observed for the following signs: encrustation, nodules, mucocutaneous separation and varicose veins; for the following diagnoses: mucocutaneous dehiscence, allergic contact dermatitis, encrustation and varicose veins (caput medusae); for the following treatments: recommending a diet rich in vitamin C/blueberries, applying acetic acid dressings, applying cold and topical tacrolimus treatment. CONCLUSIONS: The most easily identifiable lesions were those most prevalent and with visible signs. There was a lower level of agreement in identifying lesions for which photographs required additional information (laboratory data, description of signs and symptoms, type of diet and level of self-care). It is important to train nurses caring for ostomates to correctly describe ostomy-related lesions, which is important for nursing records, continuity of care and telehealth care.

Peristomal Pyoderma Gangrenosum in a Rectal Cancer Patient With an Ileostomy: A Case Study.

BACKGROUND: Peristomal pyoderma gangrenosum (PPG) is a rare complication mainly associated with inflammatory bowel disease. Although it has also been found in patients with an ileostomy with rectal cancer, the best treatment options in this context have not been precisely elucidated. CASE: This case report describes the importance of a multidisciplinary treatment approach for a rare case of PPG around a protective ileostomy resulting from rectal cancer. CONCLUSIONS: Early diagnosis of PPG is imperative to avoid further extension of the lesion. Aggressive management with a multidrug treatment, both topical and systemic, is recommended in severe cases. Close monitoring of the response is necessary, given the variability in the effectiveness of the treatments.
