ABSTRACT
INTRODUCCIÓN: Una de las vías de acceso a la cavidad abdominal es la laparotomía media, siendo uno de los riesgos más temidos las complicaciones postoperatorias, las cuales pueden disminuirse con difusión de una adecuada técnica quirúrgica. OBJETIVO: Generar un consenso de expertos con pasos clave para realizar una laparotomía media supra-infraumbilical, a través de la metodología Delphi. MATERIALES Y MÉTODO: Por medio de una revisión de la literatura se extrajo el detalle de 37 pasos considerados en el procedimiento, organizado en secciones de preparación, apertura y cierre, siendo evaluados por un grupo de cirujanos de 7 hospitales docentes de Chile, mediante una encuesta online. RESULTADOS: El consenso se alcanzó en dos rondas, con 28 de los 37 pasos extraídos de la literatura, considerados importantes o muy importantes para la enseñanza de la técnica. Discusión: De los 28 pasos identificados como importantes, existe un alto grado de acuerdo para la preparación y apertura de una laparotomía, a diferencia del cierre en el cual no se observa una preferencia clara entre el cierre en una o varias capas entre el peritoneo y la fascia, debiendo analizarse en cada caso específico. CONCLUSIÓN: La identificación de 28 pasos estandarizados constituye un aporte en los programas de formación de residentes y en el desarrollo de modelos de simulación adecuados para la replicación del procedimiento. El aprendizaje correcto de la técnica basado en evidencia es fundamental para disminuir el riesgo de complicaciones asociadas, especialmente en el postoperatorio.
INTRODUCTION: Traditionally, the main surgical technique to access the abdominal cavity has been midline incision laparotomy, being postoperative complications a main concern. Proper teaching-learning methods could help improving the success of this procedure. AIM: Establish an expert's consensus throughout the Delphi Methodology regarding the main steps that need to be considered in a midline laparotomy. MATERIALS AND METHOD: Literature review was conducted, 37 steps were identified and grouped in 3 sections; preparation of the skin, opening incision, and closure. These steps were evaluated online by surgeons of 7 teaching hospitals in Chile. RESULTS: Consensus was reached in two rounds, 28 of the 37 steps were identified as important or very important for the procedure. DISCUSSION: There is a high level of agreement in steps related to preparation of the skin and opening incision. However, there is not a consensus regarding closure of the peritoneum and fascia in one or more layers, being a case to case decision. CONCLUSIONS: Establishment of 28 standardized steps constitutes a contribution to resident teaching programs and the development of simulation materials as an active learning strategy. Satisfactory learning outcomes have a direct impact in the success of the procedure and a lower rate of complications.

BACKGROUND: Incisional hernias are a frequent complication, and their prevention includes proper closure of the abdominal wall. METHODS: A prospective study was conducted at a third-level hospital after the introduction of a midline laparotomy closure protocol. An objective measurement of the suture length to incision length ratio was made. and the postoperative results were analyzed. RESULTS: 127 patients were included and 34 of them (26.8%) had received a technically deficient closure. Incisional hernia was described in 20.5% of cases. An improvement in the quality of the abdominal wall closure was demonstrated over time. CONCLUSION: The abdominal wall closure was deficient in nearly one- quarter of the laparotomies performed at a third-level medical center. A protocol improved the quality of the laparotomy closure.
