ABSTRACT
ABSTRACT

Background:

It is important but difficult to treat complex fistula-in-ano due to the high recurrent rate and following incontinence. Ligation of the intersphincteric fistula tract (LIFT), a novel surgical procedure with the advantage of avoiding anal incontinence, has a variable success rate of 57-94.4 %.

Aim:

To evaluate the long-term outcomes of modified LIFT operative procedure - ligation of intersphincteric fistula tract - to treat complex fistula-in-ano.

Methods:

Retrospective analysis of 62 cases of complex fistula-in-ano. The group was treated with the modified approach of LIFT (curved incision was made in the anal canal skin; purse-string suture was performed around the fistula; the residual fistulas were removed in a tunnel-based way) and had a follow-up time of more than one year. Patient´s preoperative general condition, postoperative efficacy and their anal function were compared.

Results:

The median age of the participants was 34, and 43 (69.4%) cases were male. Forty-one (66.1%) cases were of high transsphincteric fistula, four (6.5%) cases of high intrasphincter fistula, and 17 (27.4%) cases of anterior anal fistula in female. The median follow-up duration was 24.5 (range, 12-51) months. The success rate in the end of follow-up was 83.9% (52/62). The anorectal pressure and Cleveland Clinic Florida Fecal Incontinence (CCF-FI) evaluated three months before and after the operation did not find apparent changes.

Conclusions:

Compared with LIFT, the modified LIFT remarkably reduces postoperative failure and the recurrence rate of complex fistula with acceptable long-term outcomes.
RESUMO
RESUMO Racional É importante, mas difícil de se tratar fístula anal complexa devido à alta taxa de recorrência e de incontinência pós-operatória. A ligadura do trajeto da fístula interesfincteriana (LIFT) - um novo procedimento cirúrgico com a vantagem de evitar a incontinência anal - tem taxa de sucesso variável entre 57-94,4%.

Objetivo:

Avaliar os resultados em longo prazo do procedimento cirúrgico LIFT modificado - ligadura do trato interesfincteriano com fístula - para tratar fístula complexa anal.

Métodos:

Análise retrospectiva de 62 casos de fístula complexa no ânus tratados com abordagem modificada de LIFT (incisão curva na pele do canal anal; sutura em bolsa realizada em torno da fístula; as fístulas residuais removidas em um túnel) e teve tempo de acompanhamento de mais de um ano. A condição geral pré-operatória dos pacientes, a eficácia pós-operatória e a função anal foram comparadas.

Resultados:

A mediana de idade dos participantes foi de 34 anos, e 43 (69,4%) dos casos eram de homens. Quarenta e um (66,1%) casos eram de fístula transesfincteriana alta, quatro (6,5%) de fístula intra-esfincteriana alta e 17 (27,4%) de fístula anal anterior em mulheres. A mediana da duração do acompanhamento foi de 24,5 meses (12-51). A taxa de sucesso no final do acompanhamento foi de 83,9% (52/62). A pressão anorretal e a Incontinência Fecal da Cleveland Clinic Florida (CCF-FI) avaliadas três meses antes e após a operação não encontraram alterações aparentes.

Conclusões:

Comparado com o LIFT, o LIFT modificado reduz notavelmente a falha pós-operatória e a taxa de recorrência de fístula complexa com resultados aceitáveis em longo prazo.
