Intradermal botulinum toxin a for peristomal hyperhidrosis: a case study.

Background: Peristomal hyperhidrosis can interfere with pouch adherence, resulting in pouch leakage and peristomal skin damage.

Case: A patient with autonomic dysregulation resulting in excessive sweating (hyperhidrosis) experienced difficulty with adherence of her ileostomy appliance. Two hundred units of botulinum toxin A (BTX-A) were injected in the dermis of the surrounding skin in order to improve adherence of her pouching system and alleviate moisture of her peristomal skin.
