About this study
Official title: Efficacy of Photodynamic Therapy and Intra-lesional 5-wing in Complex Perianal Fistula
Objective: Validate and analyze the results of intralesional photodynamic therapy in the treatment of complex anal fistula.
Methods: Prospective observational study including patients treated for complex anal fistula who underwent intralesional photodynamic therapy (i-PDT). Patients were included with a minimum follow up of 1-year, in order to evaluate recurrence, continence and postoperative morbidity. Intralesional 5-aminolevulinic acid gel 2% was directly injected into the fistula. The internal and external orifices were closed. After an incubation period of 2 h, the fistula was irradiated using an optical fibre connected to a red laser (MULTIDIODE 630 PDT, INTERmedic, Spain) operating at 1 W/ cm for 3 min (180 Joules).
