Patrones de recurrencia/persistencia en la operación de LIFT para la fístula anal de origen criptoglandular. Estudio observacional a largo plazo

In our experience, the LIFT technique is a safe and reproducible procedure with low morbidity, no repercussion on continence and a success rate over 70%. There are 3 types of recurrence: the intersphincteric fistula, the original fistulatula (trans- or supra-sphincteric) and the residual external tract. Considering the types of recurrence, only 12,7% of patients need more complex surgery to solve their pathology. The rest of the recurrences/persistence were solved by simple procedures (fistulotomy in intersphincteric forms and legrado in residual tracts).
