| Abstrakt: | Purpose: To assess the efficacy of Botulinum toxin A (BoNT-A) in the treatment of patients with hypercontractile stomas resulting in repeated pouching system failures and leaks. Design: Prospective case series. Subjects and Setting: Ten consecutive patients who presented to the outpatient stoma clinic with actively contractile stomas that shortened spasmodically resulting in leaks were offered treatment with BoNT-A if treatment with other measures had been unsuccessful. Methods: Following an observed reduction in the peristalsic shortening of a stoma after intradermal injection of BoNT-A for hyperhidrosis, we conducted a prospective case series of 10 patients with pouch adhesive failures attributed to spasmodic shortening of the stoma. Ten patients, 3 with urostomies and 7 with ileostomies, were offered BoNT-A injection. The first was treated cautiously with 15 units of BoNT-A injected into the muscularis layer, followed by an additional 25 units injected 1 month later. Subsequent patients received doses varying from 50 to 100 units. Ongoing treatments ranged 50 to 100 units every 3 to 6 months. Results: Seventy percent (n = 7) of patients reported a useful reduction in leakage and pouching system seal failures. In these 7 patients, the frequency of pouch changes changed from an average of 2.18 to 0.44 per day (over all 10 patients this was a change from an average of 2.35 per day to 1.16 per day). No adverse side effects were reported. Conclusion: Findings from this clinical case series suggest that BoNT-A may be a promising treatment in the management of patients with leaks caused by actively contracting stomas. |
