The aim of this study was to determine if a new sphincter muscle-sparing technique that uses
fibrin glue was effective in closing all types of anal
fistulas. All patients with anal
fistulas who were seen by a single surgeon over a 2-year period were treated with
fibrin glue. Six to 8 weeks after a seton was placed in the
fistula tract, either autologous
fibrin glue or commercially available
fibrin sealant was used to close the
fistula tract. Twenty patients were treated with a mean follow-up of 10 months. Etiology of the anal
fistulas was as follows: cryptoglandular in 13,
Crohn's disease in four, and miscellaneous in three.
Fibrin glue closure of the
anal fistula was successful initially in 15 patients (75%) and was successful after a second treatment in two additional patients, for an overall
fibrin glue fistula closure rate of 85% (17 of 20). Functional results have remained excellent with no patient reporting any change in continence
after treatment.
Fibrin glue is simple and effective treatment for all anal
fistulas with excellent functional results.
