Popis: Chronic leg ulcers represent a major health-care problem with considerable socioeconomic impact. Patients with seemingly therapy-resistant leg ulcers are common to all clinics. The purpose of the present study was to (1) examine a group of patients with nonhealing venous leg ulcers treated with a double-layer bandage and (2) evaluate whether the addition of an interactive hydrocolloid wound dressing could initiate healing in these patients. Twenty-two patients with ulcers caused by venous insufficiency were included. The patients had a mean ulcer duration of 27.6 years. Duration of the present ulcer was at least 1 year (mean >/= 4.1 years). Twenty of the 22 patients showed massive lipodermatosclerosis. Before inclusion, all patients had used double-layer bandage consisting of a zinc-impregnated bandage or stocking and a self-adhesive compression bandage for 1 year or longer without improvement. The new regimen was a triple-layer treatment with the hydrocolloid water applied over the ulcer and the traditional double-layer bandage unchanged. Three patients were dropped from the study. Nineteen patients were followed until healing or for 10 months. Nine of the 19 patients who completed the study healed. Ulcer area was reduced by 70% or greater in 7 patients and by 30% to 40% in two patients. One ulcer did not respond to the treatment and worsened slightly. The results of this study were encouraging and indicate that the triple-layer treatment with the hydrocolloid dressing applied to the ulcer should be evaluated in a randomized, controlled study in patients with less pessimistic prognoses.
