    BackgroundThe indications and efficacy of endoluminal vacuum therapy for the management of colorectal/coloanal anastomotic leakage are not well defined.ObjectiveThis study aimed to evaluate the efficacy and to define adequate indications of endoluminal vacuum therapy to treat colorectal/coloanal anastomotic leakage.DesignThe retrospective cohort evaluated in this study is based on a prospectively maintained database.SettingsThis study was conducted in 8 centers from the French GRECCAR study group.PatientsPatients with colorectal/coloanal anastomotic leakage treated with endoluminal vacuum therapy were included.Main Outcome MeasuresThe primary outcome measured was the success rate of endoluminal vacuum therapy defined by the complete healing of the perianastomotic sepsis and a functional anastomosis. The predictive factors of success of endoluminal vacuum therapy and long-term functional result (low anterior resection syndrome score) were also analyzed.ResultsAmong 62 patients treated for an anastomotic leakage of colorectal/coloanal anastomosis from 2012 to 2017, 47 fulfilled the inclusion criteria. The patients had a mean of 6.6 (±5.8) replacements for a total of 27 (±34) days treatment duration, associated with diverting stoma in 81%. After 37 months median follow-up, a successful treatment of anastomotic leakage using endoluminal vacuum therapy could be achieved in 26 patients (55%). The success rate was improved in patients undergoing primary endoluminal vacuum therapy compared to salvage endoluminal vacuum therapy (73% vs 33%, p = 0.006) and when endoluminal vacuum therapy was initiated within 15 days compared to more than 15 days after the diagnosis of anastomotic leakage (72.4% vs 27.8%, p = 0.003). At 12 months, 53% of patients who responded had minor low anterior resection syndrome and only 3 necessitated anastomotic stricture dilation.LimitationsThis was a noncomparative cohort study.ConclusionEndoluminal vacuum therapy appears to be effective to treat colorectal anastomotic leakage especially when it is used as primary treatment of the fistula. Long-term functional outcome of patients undergoing conservative management of anastomotic leakage may be improved with endoluminal vacuum therapy.

RESULTADOS A CORTO Y LARGO PLAZO DE LA TERAPIA DE VACÍO ENDOLUMINAL PARA LA FUGA ANASTOMÓTICA COLORRECTAL O COLOANAL: RESULTADOS DE UN ESTUDIO DE COHORTE MULTICÉNTRICO A NIVEL NACIONAL DEL GRUPO FRANCÉS GRECCAR: Las indicaciones y la eficacia de la terapia de vacío endoluminal para el tratamiento de la fuga anastomótica colorrectal / coloanal no están bien definidas.Evaluar la eficacia y definir indicaciones adecuadas de la terapia de vacío endoluminal para tratar la fuga anastomótica colorrectal / coloanal.Cohorte retrospectivo basada en una base de datos mantenida prospectivamente.Este estudio se realizó en 8 centros del grupo de estudio Francés GRECCAR.Se incluyeron pacientes con fuga anastomótica colorrectal / coloanal tratados con terapia de vacío endoluminal.Tasa de éxito de la terapia de vacío endoluminal definida por la curación completa de la sepsis perianastomótica y una anastomosis funcional. También se analizaron los factores predictivos del éxito de la terapia de vacío endoluminal y el resultado funcional a largo plazo (puntaje bajo del síndrome de resección anterior).Entre 62 pacientes tratados por una fuga anastomótica de anastomosis colorrectal / coloanal de 2012 a 2017, 47 cumplieron los criterios de inclusión. Los pacientes tuvieron una media de 6.6 (±5.8) reemplazos para un total de 27 (±34) días de duración del tratamiento, asociado con estoma de desvio en el 81%. Después de una mediana de seguimiento de 37 meses, se pudo lograr un tratamiento exitoso de la fuga anastomótica usando terapia de vacío endoluminal en 26 pacientes (55%). La tasa de éxito mejoró en pacientes sometidos a terapia de vacío endoluminal primaria en comparación con la terapia de vacío endoluminal de rescate (73% frente a 33%, p = 0.006) y cuando la terapia de vacío endoluminal se inició dentro de los 15 días en comparación con más de 15 días después del diagnóstico de fuga anastomótica (72.4% vs 27.8%, p = 0.003). A los 12 meses, el 53% de los pacientes que respondieron tenían síndrome de resección anterior baja leve y solo 3 necesitaban dilatación de estenosis anastomótica.Estudio de cohorte no comparativo.La terapia de vacío endoluminal parece ser efectiva para tratar la fuga anastomótica colorrectal, especialmente cuando se usa como tratamiento primario de la fístula. El resultado funcional a largo plazo de los pacientes sometidos a un tratamiento conservador de la fuga anastomótica puede mejorarse con la terapia de vacío endoluminal.
