- Abstract : BACKGROUND: Ablation of anal fistula tract using a radial laser-emitting probe is a sphincter-preserving technique. OBJECTIVE: The purpose of this study was to assess long-term outcomes of laser ablation of fistula tract. DESIGN: This was a retrospective analysis of the long-term outcomes of 100 patients who underwent laser ablation of fistula tract. SETTINGS: This was a single-center study from a tertiary center in Turkey. PATIENTS: All of the patients with fistula-in-ano were included. Exclusion criteria were the presence of perianal abscess, underlying Crohn's disease, fistula tract <2 cm, fistulas suitable for simple fistulotomy, and intersphincteric fistulas originated from posterior located chronic anal fissure. INTERVENTIONS: A probe housing a 15-watt laser emitting at a wavelength of 1470 nm and an energy level of 100 to 120 joule/cm was used. MAIN OUTCOME MEASURES: No discharge, no symptoms, and fibrotic scar on skin where previously an external opening was present were defined as overall complete healing . All results other than overall complete healing were accepted as failure. RESULTS: A total of 100 patients underwent laser ablation of fistula tract with a median age of 42 years (range, 21–83 y). The majority of them were men. The overall success rate was 62% (95% CI, 52%–71%) in a median follow-up time of 48 months (range, 6–56 mo). None of the patients experienced permanent major or minor anal incontinence.

None of the patients experienced permanent major or minor anal incontinence. LIMITATIONS: The retrospective nature of this study is its main limitation. Other limitations consist of phone interview for follow-up of the majority of the patients, single-institution data, and the relatively small number of patients. CONCLUSIONS: Laser ablation of the fistula tract is a sphincter-preserving procedure with an acceptable long-term success rate. See Video Abstract at http://links.lww.com/DCR/B186 . Resultados a Largo Plazo de la Ablación con Láser del Tracto en la Fístula Anal: Una Considerable Opción en la Preservación del Esfínter: ANTECEDENTES: La ablación con una sonda radial emisora de láser del tracto de fístula anal, es una técnica de preservación del esfínter. OBJETIVO: Evaluar los resultados a largo plazo de la ablación con láser del tracto fistuloso. DISEÑO: Análisis retrospectivo de los resultados a largo plazo de 100 pacientes que se sometieron a la ablación con láser del tracto de fístula. AJUSTES: Este es un estudio de centro único de un centro terciario en Turquía. PACIENTES: Fueron incluidos todos pacientes con fístula anal. Los criterios de exclusión fueron la presencia de absceso perianal, enfermedad de Crohn subyacente, tracto de fístula menor de 2 cm, fístulas adecuadas para fistulotomía simple y fístulas interesfintéricas originadas en una fisura anal crónica posterior. INTERVENCIONES: Se utilizó una sonda que alberga un láser de 15 vatios que emite a una longitud de onda de 1, 470 nm y un nivel de energía de 100-120 julios / cm. PRINCIPALES MEDIDAS DE RESULTADO: Sin secreción, sin síntomas y la cicatriz fibrótica en la piel, donde anteriormente estaba presente la apertura externa, se definió como "curación completa general." Todos los resultados que no sean "curación completa en general" se aceptaron como fracaso. RESULTADOS: Cien pacientes fueron sometidos a ablación con láser del tracto de fístula anal, con una edad media de 42 (21-83) años. La mayoría de ellos fueron varones. La tasa de éxito general fue del 62% (intervalo de confianza del 95%, 52%-71%) en una mediana de tiempo de seguimiento de 48 (6-56) meses. Ninguno de los pacientes experimentó incontinencia anal mayor o menor permanente. LIMITACIONES: La naturaleza retrospectiva de este estudio es su principal limitación. Otras limitaciones consisten en una entrevista telefónica para el seguimiento de la mayoría de los pacientes, datos de una sola institución y un número relativamente pequeño de pacientes. CONCLUSIONES: La ablación con láser del tracto de la fístula anal, es un procedimiento de preservación del esfínter y con una aceptable tasa de éxito a largo plazo.
