Introduction
This study aimed to evaluate the applicability, safety, results, and functional performance of Permacol™ collagen paste injection in patients with an anal fistula.
Methods
Thirty-one patients with anal fistula underwent Permacol™ collagen paste injection between February 2015 and February 2017. The patients were followed up for a total of 12 months with recovery conditions monitored at intervals of 3, 6, and 12 months. Preoperative insertion of seton was performed in 15 patients for a period of 6–8 weeks and 2 patients for a period of 12 weeks.
Results
A trans-sphincteric anal fistula was present in 20 patients and an intersphincteric fistula was present in 11 patients. There was a recurrence in 7 patients (22.5%): 1 patient (3.2%) after 1-month follow-up, 3 patients (9.7%) after 3-month follow-up, 2 patients (6.5%) after 6-month follow-up, and 1 patient (3.2%) after 12-month follow-up. A complete recovery was observed in 24 (77.5%) patients after a 12-month follow-up. The mean Fecal Incontinence Severity Index score was 0.29 ± 0.64 preoperatively and 0.55 ± 1.03 after 12 months.
Conclusion
In this study, we show that treatment of patients with an anal fistula by injection of Permacol™ is a safe and successful method that does not compromise continence.
