Papel de la terapia presión negativa en la prevención de infección del sitio quirúrgico en cirugía colorrectal / Role of negative pressure wound therapy in the prevention of surgical site infection in colorectal surgery

Introducción: La infección del sitio quirúrgico (SSI) es una de las principales complicaciones quirúrgicas, con una incidencia del 10-20% en cirugía colorrectal. Las terapias basadas en presión negativa (NPWT) han mostrado su eficacia en el tratamiento de heridas crónicas, traumáticas, en las dehiscencias de piel, en el uso de colgajos o injertos. El objetivo principal del estudio es valorar la eficacia de NPWT en la prevención de SSI en cirugía colorrectal. Los objetivos secundarios son valorar la reducción del ingreso hospitalario y analizar los factores de riesgo de SSI. Métodos: Estudio casos y controles prospectivo. Ochenta pacientes intervenidos tras diagnóstico de enfermedad colorrectal, de forma programada o urgente durante el año 2017. Cuarenta pacientes fueron tratados con NPWT preventivo durante una semana. Cuarenta pacientes fueron tratados según protocolo habitual postoperatorio de cuidado de herida quirúrgica. Resultados: No se encontraron diferencias entre NPWT y grupo control en variables demográficas, comorbilidades, abordaje quirúrgico, indicación urgente o programada, preparación colónica o procedimiento quirúrgico. Se objetivó SSI con el empleo de NPWT en 3 (8%) pacientes (IC del 95%, 0-17,5). SSI en 10 (25%) pacientes (IC del 95%, 12,5-37,5) (p = 0,034); OR 0,7 (IC del 95% 0,006-0,964). La estancia hospitalaria en el grupo NPWT fue de 8 días vs. 12 días en el grupo control (0 p= 0,22). En el análisis multivariante se encontró como único factor relacionado con SSI la preparación colónica (p = 0,047; OR: 0,8, IC 0,45-0,93). Conclusiones: El uso de dispositivos NPWT para la cobertura de incisiones cerradas tras cirugía colorrectal puede disminuir la incidencia de SSI

Background: Surgical site infection (SSI) is one of the most frequent complications in colorectal surgery. It is diagnosed in 10 - 20% of colorectal procedures. Negative Pressure Wound Therapy (NPWT) has shown efficacy in the treatment of chronic and traumatic wounds, wound dehiscence, flaps and grafts. The main objective of this study is to assess NPWT in the prevention of SSI in colorectal surgery. Hospital stay reduction and SSI risk factors are secondary objectives. Methods: We present a prospective case-control study including 80 patients after a colorectal diagnosis and surgical procedure (elective and non-elective) in 2017. Forty patients were treated with prevention NPWT for one week. Forty patients were treated according to the standard postoperative surgical wound care protocol. Results: No significant differences were found in demographic variables, comorbidities, surgical approach, elective or non-elective surgery, mechanical bowel preparation and surgical procedure. Three patients has SSI in the NPWT group (8%) (95%CI 0 - 17.5). Ten patients presented SSI in the control group (25%) (95%CI 12.5 - 37.5) (p = 0.034); OR 0.7 (95%CI 0.006-0.964). Hospital stay in the NPWT group was 8 days versus 12 days in the non-NPWT group (p = 0.22). In the multivariate analysis, mechanical bowel preparation was found to be the only risk factor for SSI (p = 0.047; OR: 0.8, CI 0.45-0.93). Conclusions: NPWT is a useful SSI prevention treatment in colorectal surgery
