Use of double-layered covered esophageal stents in post-surgical esophageal leaks and esophageal perforation: Our experience. / Uso de prótesis esofágicas cubiertas de doble malla en fístulas esofágicas postquirúrgicas y perforaciones esofágicas: experiencia en nuestro centro.

INTRODUCTION: The use of esophageal stents for the endoscopic management of esophageal leaks and perforations has become a usual procedure. One of its limitations is its high migration rate. To solve this incovenience, the double-layered covered esophageal stents have become an option. OBJECTIVES: To analyse our daily practice according to the usage of double-layered covered esophageal metal stents (DLCEMS) (Niti S™ DOUBLE™ Esophageal Metal Stent Model) among patients diagnosed of esophageal leak or perforation. METHODS: Retrospective, descriptive and unicentric study, with inclusion of patients diagnosed of esophageal leak or perforation, from November 2010 until October 2018. The main aim is to evaluate the efficacy of DLCEMS, in terms of primary success and technical success. The secondary aim is to evaluate their (the DLCEMS) safety profile. RESULTS: Thirty-one patients were firstly included. Among those, 8 were excluded due to mortality not related to the procedure. Following stent placement, technical success was reached in 100% of the cases, and primary success, in 75% (n=17). Among the complications, stent migration was present in 21.7% of the patients (n=5), in whom the incident was solved by endoscopic means. CONCLUSIONS: According to our findings, DLCEMS represent an alternative for esophageal leak and perforation management, with a high success rate in leak and perforation resolutions and low complication rate, in contrast to the published data. The whole number of migrations were corrected by endoscopic replacement, without the need of a new stent or surgery.

The safety of deep sedation with propofol controlled by the endoscopist in endoscopic retrograde cholangiopancreatography (ERCP): a prospective study in a tertiary hospital.

INTRODUCTION: propofol administered by an endoscopist with a trained nurse has evolved as an alternative to anesthesia monitoring and is increasingly common in the routine clinical practice, even in advanced endoscopy. OBJECTIVE: to evaluate the safety of deep sedation with endoscopist-controlled propofol in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). MATERIAL AND METHODS: this was a prospective study in patients undergoing ERCP under deep sedation with propofol. Different patient-related variables were included and the initial and final data on oxygen saturation (SatO2), blood pressure (BP) and heart rate (HR) were recorded in order to determine the presence of adverse events due to sedation (hypoxemia, hypotension, or bradycardia). RESULTS: a total of 661 patients underwent ERCP under sedation with propofol over a 24-month period. The rate of recorded adverse events was 9.7%. The most frequent adverse event was hypoxemia (5.7%), followed by bradycardia (2.4%) and hypotension (1.6%). According to the univariate analysis, the occurrence of adverse events due to sedation (AES) was associated with an ASA score ≥ III (p = 0.026), older patients (p = 0.009), higher body mass index (BMI) (p = 0.002) and a longer exploration time (p = 0.034). The induction dose of propofol was also associated with a greater likelihood of adverse events (p = 0.045) but not the total dose of propofol administered (p = 0.153). According to the multivariate logistic regression analysis, age, body mass index (BMI) and the duration of the exploration were independent predictors of SAE (p < 0.05). CONCLUSION: deep sedation with propofol controlled by trained endoscopy staff is a safe method in complex endoscopic procedures such as ERCP.

Uso de prótesis esofágicas cubiertas de doble malla en fístulas esofágicas postquirúrgicas y perforaciones esofágicas: experiencia en nuestro centro / Use of double-layered covered esophageal stents in post-surgical esophageal leaks and esophageal perforation: Our experience

Introducción: El uso de prótesis esofágicas para el manejo endoscópico de fístulas y perforaciones se ha convertido en un procedimiento habitual. Una de sus limitaciones es su alta tasa de migración. Para resolver esta situación, se ha propuesto el uso de prótesis cubiertas de doble malla.Objetivos: Analizar nuestra experiencia práctica en el empleo de prótesis esofágicas cubiertas de doble malla (PECDM) (modelo Niti S™ DOUBLE™ Esophageal Metal Stent) en pacientes con fístula o perforación esofágica.Material y métodos: Estudio retrospectivo, descriptivo y unicéntrico, donde se incluyen pacientes con diagnóstico de fístula o perforación esofágica, desde noviembre 2010 hasta octubre 2018. Como objetivo primario, se evaluará su eficacia en términos de éxito técnico. Como objetivo secundario, se analizará su perfil de seguridad.Resultados: Se incluyeron inicialmente un total de 31 pacientes, siendo 8 de ellos excluidos por fallecimiento por causas ajenas a la técnica. Se detectó un éxito técnico del 100%, con un éxito primario del 75% tras la recolocación de la prótesis. Entre sus complicaciones, la migración ocurrió en un 21,7% de los pacientes (n=5), resolviéndose vía endoscópica en el 100% de los casos.Conclusiones: Según nuestros hallazgos, las PECDM suponen una alternativa en el tratamiento de fístulas y perforaciones esofágicas, con una alta tasa de éxito en la resolución de fístulas y baja de complicaciones, en contraste con lo expuesto en las series publicadas. En todos los casos, la migración de la prótesis se resolvió mediante recolocación endoscópica, sin requerir nueva prótesis ni cirugía.(AU)

[Effectiveness of an educational program for reducing blood culture contamination]. / Efectividad de un programa formativo para disminuir los hemocultivos contaminados.

INTRODUCTION: Blood culture contaminations can lead to unnecessary diagnostic procedures and treatments, increasing workload, length of stay, and costs. OBJETIVES: Development of an educational program to reduce contamination rates. MATERIAL AND METHODS: Our study compared contamination rates (CR) between a pre-intervention period (Ppre) and post-intervention period (Ppos), where clinical charts from patients with positive blood cultures were reviewed. Intervention consisted of a questionnaire where knowledge of blood culture practice and its significance was assessed. Results are discussed and explained. RESULTS: A presentation on blood culture guidelines was discussed in every nurse station. There was a median of 64% (40.8-78.5) attendance rate. The median of correct answers was 69% in the Ppre (54.1-83.3) with 85.7% (83.3-100) in the Ppos, indicating an improvement in 85.7% of the departments that could be compared. There were 136 (4.2%) contaminants in the Ppre and 186 (6.05%) in the Ppos (P=.005). Among the different departments the average of CR varied from 5% vs 7.5% (P=.79) between 2011 and 2012. Only 2 departments reduced CR by 2% to 2.5%, the difference was not significant. CONCLUSIONS: The intervention failed to reduce overall contamination rates, but knowledge of blood culture practice improved. Our results identified the errors that will help us to design a successful approach in future follow-up programs.

Efectividad de un programa formativo para disminuir los hemocultivos contaminados / Effectiveness of an educational program for reducing blood culture contamination

INTRODUCCIÓN: Los hemocultivos contaminados (HC) conllevan un incremento de pruebas diagnósticas, tratamientos innecesarios, aumento de la carga asistencial, estancia hospitalaria y costes. Objetivos Disminución de los HC a través de un programa educacional. Material y métodos Periodo preintervención (Ppre): valoración clínica restrospectiva de los hemocultivos positivos y análisis de indicadores de contaminación. Periodo postintervención (Ppos), tras programa educacional, se comparó la incidencia de contaminación entre ambos periodos. La formación comprendió: un cuestionario donde se valoraba el grado de conocimientos acerca de la técnica de extracción, el significado de los HC, su diagnóstico y prevención, la impartición de sesiones y la revisión de resultados. ResultadosSe impartieron sesiones formativas en todas las unidades de hospitalización. La mediana de participación fue del 64% (40,8-78,5). La mediana de aciertos en el cuestionario fue del 69% en el Ppre (54,1-83,3) y de 85,7% (83,3-100) en el Ppos, mejorando en el 85,7% de las unidades que pudieron compararse. Durante el Ppre hubo 136 (4,2%) HC y 186 (6,05%) fueron HC en el Ppos (p = 0,005). La mediana de HC por unidades entre 2011 y 2012 fue del 5 vs. 7,5% (p = 0,79). Solo en 2 unidades se objetivó una reducción del 2 y del 2,5% que no fue significativa. CONCLUSIONES: Nuestro programa formativo no consiguió reducir los HC en el periodo del estudio pero logró una mejoría en la capacitación de las enfermeras. Los resultados nos permitieron identificar los problemas que necesitan modificarse de cara a conseguir mejores resultados y poder implantar un programa continuado
