fistula in ano, anal fistula, recurrence, costs
Brief summary
The purpose of this study is to determine whether anal fistula plug or endorectal advancement flap is more successful in the treatment of anal fistulas and compared both procedures with regards to cost.
Detailed description
A detailed analysis will be performed to determine independent predicting factors of recurrence and of higher costs.
