Evaluation of Cholestyramine 15% Ointment in Relieving Pruritus and Burning After Ileostomy: A Rrandomized, Double-Blind Placebo-Controlled Clinical Trial.

Purpose/Aims: Skin irritation is a common ileostomy problem that causes burning and pruritus among patients due to the leakage of intestinal discharge around the stoma. This clinical trial was performed to evaluate the efficacy of topical cholestyramine (15%) on the reduction of the levels of burning and pruritus after an ileostomy. Material and methods: The patients were randomly divided into two groups of treatment and control (n = 15). The intervention group was subjected to one fingertip of cholestyramine, whereas the other group received the placebo ointment (approximately 0.5 g) on the skin immediately after the surgery and twice a day for 2 months. The primary outcome measure was the severity of burning and pruritus measured by a visual analog scale at different times after an ileostomy. Results: Out of 34 patients, four cases were excluded due to the inappropriate completion of the questionnaire (n = 2) and unwillingness to attend the follow-up visits (n = 2). Therefore, 30 patients were included in the study. The levels of burning among patients in the cholestyramine were lower in weeks 3, 4, and 8 compared to the placebo group. Moreover, lower levels of pruritus were observed among patients in the treatment group in weeks 4 and 8 after an ileostomy. No side effects were reported among the patients. Conclusions: Topical cholestyramine was found to be effective in the management of burning and pruritus resulting from an ileostomy among the population under study.
