Cryosurgery for Pruritus Ani

Chapter

Abstract

Pruritus ani is a male predominant disorder of perianal itching that is associated with an itch-scratch cycle leading to lichenification. It can be caused by infection, medications, irritation, systemic disease, and colorectal/anal disease. Dermatologic diseases associated with pruritus ani include psoriasis, seborrheic keratosis, atopic dermatitis, contact dermatitis, lichen sclerosus, lichen simplex chronicus, Paget’s disease, and Bowen’s disease. The primary treatment for pruritus ani is maintenance of anal hygiene. Steroid creams, capsaicin, tacrolimus, and injectable methylene blue have been used with mixed success. Cryosurgery disrupts nerve endings, causing cessation of the itch-scratch cycle. Only 1 out of 18 patients had recurrence after cryosurgery. Cryosurgery is an effective option for pruritus ani due to its cost-effectiveness and low morbidity.
