Barrett's esophagus and esophageal cancer after sleeve gastrectomy. Myth or reality?

Sleeve gastrectomy has become the most performed bariatric surgery technique in the world. This bariatric technique has been related to the appearance of gastroesophageal reflux and recently with de novo Barrett's esophagus. It is not clear that this leads to an increased incidence of esophageal adenocarcinoma. In this review we analyze the current scientific literature to try to answer the true incidence of Barrett's esophagus and adenocarcinoma after sleeve gastrectomy, and whether these data should make us change the indications for this technique.

Aprendizaje basado en la simulación: valoración de los objetivos docentes en un programa de abdomen agudo y oclusión intestinal en cirugía general / Simulation-based learning: assessment of the teaching objectives in a program of acute abdomen and intestinal occlusion in general surgery, in medicine degree students

Introducción y objetivo: Analizar el logro de los objetivos docentes desarrollados durante el escenario de los casos de simulación a través de la valoración del profesor, los participantes observadores y quien realiza la propia simulación. Sujetos y métodos: Estudio observacional, prospectivo, descriptivo y unicéntrico, realizado con estudiantes de tercer curso de Medicina de la Universitat Autònoma de Barcelona. Se evalúan los objetivos docentes para cada caso clínico simulado por parte de los estudiantes que realizan la simulación, los observadores y el profesor. La evaluación numérica sigue una escala de tipo escala visual analógica y la categórica los clasifica en conseguidos, parcialmente conseguidos y no conseguidos. El estado nervioso y la comodidad de los alumnos también se evalúan numéricamente. Resultados: Se ha registrado la valoración de los objetivos de 929 participantes. La evaluación de los objetivos tiene un valor medio superior a 7 para cada uno de ellos. Existe una diferencia de 1,5-2 puntos en la valoración media entre el primer caso y el último, y no hay ningún alumno que no consiga los objetivos en el último caso. Se describe un estado de nervios alrededor de 4,5 y de comodidad alrededor de 7, sin diferencias entre los distintos evaluadores. Conclusiones: El logro de los objetivos se consigue de forma notable. Entre el primer caso y el último existe una significativa diferencia en el grado de obtención de los objetivos. No hay una relación entre el estado emocional de los participantes y la consecución de los objetivos.(AU)

Introduction and aim: To analyze the achievement of the educational objectives developed during the scenario of the simulation cases through the assessment of the teacher, the observer participants and the person who performs the simulation itself. Subjects and methods: Observational, prospective, descriptive and single-center study, carried out with 3rd year Medicine students at the Universitat Autònoma de Barcelona. The teaching objectives for each simulated clinical case are evaluated by the students who carry out the simulation, the observers and the teacher. The numerical evaluation follows a VAS-type scale and the categorical one classifies them as achieved, partially achieved and not achieved. The nervous state and comfort of the students are also evaluated numerically. Results: The evaluation of the objectives of 929 participants has been registered. The evaluation of the objectives has an average value greater than 7 for each one of them. There is a difference of 1.5-2 points in the average assessment between the first case and the last, with no student not achieving the objectives in the last case. A state of nerves around 4.5 and comfort around 7 is described, with no differences between the different evaluators. Conclusions: The achievement of the objectives is achieved in a remarkable way. Between the first case and the last, there is a significant difference in the degree of achievement of the objectives. There is no relationship between the emotional state of the participants and the achievement of the objectives.(AU)

Alterations in tissue oxygen saturation measured by near-infrared spectroscopy in trauma patients after initial resuscitation are associated with occult shock.

PURPOSE: Persistent occult hypoperfusion after initial resuscitation is strongly associated with increased morbidity and mortality after severe trauma. The objective of this study was to analyze regional tissue oxygenation, along with other global markers, as potential detectors of occult shock in otherwise hemodynamically stable trauma patients. METHODS: Trauma patients undergoing active resuscitation were evaluated 8 h after hospital admission with the measurement of several global and local hemodynamic/metabolic parameters. Apparently hemodynamically stable (AHD) patients, defined as having SBP ≥ 90 mmHg, HR < 100 bpm and no vasopressor support, were followed for 48 h, and finally classified according to the need for further treatment for persistent bleeding (defined as requiring additional red blood cell transfusion), initiation of vasopressors and/or bleeding control with surgery and/or angioembolization. Patients were labeled as "Occult shock" (OS) if they required any intervention or "Truly hemodynamically stable" (THD) if they did not. Regional tissue oxygenation (rSO2) was measured non-invasively by near-infrared spectroscopy (NIRS) on the forearm. A vascular occlusion test was performed, allowing a 3-min deoxygenation period and a reoxygenation period following occlusion release. Minimal rSO2 (rSO2min), Delta-down (rSO2-rSO2min), maximal rSO2 following cuff-release (rSO2max), and Delta-up (rSO2max-rSO2min) were computed. The NIRS response to the occlusion test was also measured in a control group of healthy volunteers. RESULTS: Sixty-six consecutive trauma patients were included. After 8 h, 17 patients were classified as AHD, of whom five were finally considered to have OS and 12 THD. No hemodynamic, metabolic or coagulopathic differences were observed between the two groups, while NIRS-derived parameters showed statistically significant differences in Delta-down, rSO2min, and Delta-up. CONCLUSIONS: After 8 h of care, NIRS evaluation with an occlusion test is helpful for identifying occult shock in apparently hemodynamically stable patients. LEVEL OF EVIDENCE: IV, descriptive observational study. TRIAL REGISTRATION: ClinicalTrials.gov Registration Number: NCT02772653.

¿Es segura y eficaz la colecistostomía percutánea en la colecistitis aguda? Análisis de los efectos adversos asociados a la técnica / Is percutaneous cholecystostomy safe and effective in acute cholecystitis? Analysis of adverse effects associated with the technique

IntroducciónEl objetivo principal de nuestro estudio es valorar la seguridad y la eficacia de la colecistostomía percutánea para el tratamiento de la colecistitis aguda determinando la incidencia de efectos adversos que presentan los pacientes sometidos a este procedimiento.Material y métodoEstudio observacional con inclusión consecutiva de todos los pacientes con diagnóstico de colecistitis aguda durante 10 años. La variable principal estudiada ha sido la morbilidad (efectos adversos) recogida de forma prospectiva. Seguimiento mínimo de un año de los pacientes sometidos a colecistostomía percutánea.ResultadosDe 1.223 pacientes ingresados por colecistitis aguda, 66 pacientes han precisado colecistostomía percutánea. El 21% de estos han presentado algún efecto adverso, con un total de 22 efectos adversos. Tan solo 5 de estos efectos, presentados por 5 pacientes (7,6%), han podido ser atribuidos al propio drenaje vesicular. La mortalidad asociada a la técnica es del 1,5%. Tras la colecistostomía un tercio de los pacientes (22 pacientes) han sido sometidos a colecistectomía. Se ha realizado intervención quirúrgica urgente por fracaso del tratamiento percutáneo en 2 pacientes, y diferida en otros 2 pacientes por recidiva del proceso inflamatorio. El resto de los pacientes colecistectomizados han sido intervenidos de forma programada pudiéndose llevar a cabo el procedimiento de forma laparoscópica en 16 pacientes (72,7%) ConclusiónConsideramos la colecistostomía percutánea como técnica segura y eficaz por relacionarse con una baja incidencia de morbimortalidad, debiéndose considerar como alternativa puente o definitiva en aquellos pacientes no tributarios de colecistectomía urgente tras fracaso del tratamiento conservador con antibiótico (AU)

Consecuencias de la toma de decisiones terapéuticas con base en el resultado del FAST en pacientes politraumáticos con fractura pélvica / Consequencies of therapeutic decision-making based on FAST results in trauma patients with pelvic fracture

Introducción: La exactitud del FAST disminuye notablemente en los pacientes politraumáticos con fractura pélvica. El objetivo es analizar las consecuencias de tomar decisiones terapéuticas basadas en el resultado del FAST en los pacientes politraumáticos con fractura de pelvis. Métodos: Estudio descriptivo de pacientes con politraumatismos mayores de 16 años que han ingresado en el área de críticos o que han fallecido previamente, con fractura pélvica. El resultado del FAST ha sido comparado con un valor realmente positivo o negativo según el resultado de la laparotomía o de la tomografía computarizada.Resultados: En 13 años, se ha incluido a 263 pacientes politraumáticos con fractura pélvica (ISS medio de 31; mortalidad 19%). El FAST tenía una sensibilidad del 65,2%, una especificidad del 69%, una tasa de falsos negativos del 34,8% y una tasa de falsos positivos del 30,9%. Los pacientes hemodinámicamente inestables tenían el doble de mortalidad que los pacientes estables (27% vs. 14%, p <0,05). Los pacientes con un FAST positivo tenían mayor mortalidad que los pacientes con FAST negativo (43% vs. 26%); 4 de 10 pacientes hemodinámicamente inestables con un FAST falsamente positivo que se sometieron a laparotomía exploradora innecesaria murieron por shock hipovolémico. La mortalidad se redujo del 60 al 20% asociando un packing preperitoneal. Conclusiones: La reducida eficacia del FAST en pacientes con fractura de pelvis nos obliga a cuestionarnos las consecuencias de la toma de decisiones terapéuticas con base en sus resultados. Los pacientes con FAST falsamente positivo tienen una mortalidad mayor, que se puede reducir aplicando un packing preperitoneal. (AU)

Introduction: FAST is essential to decide if trauma patients need laparotomy, but has a notably decrease in accuracy in patients with pelvic fracture. Our objective is to analyze the consequences of therapeutic decision-making based on the FAST results in trauma patients with pelvic fracture. Methods: Descriptive study that includes trauma patients older than 16 with a pelvic fracture admitted to the critical care area or who were fallecimiento. FAST result was compared with a true positive or negative value according to the results of laparotomy or abdominal CT. We recorded diagnosis and treatment of each injury and resolution of the case, detailing the cause of death, among all variables. Results: Over the 13–year period, we included 263 trauma patients with pelvic fracture, with a mean ISS of 31 and mortality of 19%. FAST had a sensitivity of 65.2%, specificity of 69%, false negative rate of 34.8% and false positive rate of 30.9%. Hemodynamically unstable patients died twice as many stable patients (27% vs. 14%, p <0.05). Patients with positive FAST died more than negative FAST (43% vs. 26%); and 4 of 10 hemodynamically unstable patients who underwent non therapeutic laparotomy after presenting a false positive FAST died from hypovolemic shock. The mortality rate fell from 60% to 20% when preperitoneal packing was performed before angio-embolization of the pelvis. Conclusion: FAST has low accuracy in polytraumatized patients with pelvic fracture. Patients with false positive FAST have higher mortality, which can be reduce notably applying a preperitoneal packing. (AU)

Efficacy and Safety of Nonantibiotic Outpatient Treatment in Mild Acute Diverticulitis (DINAMO-study): A Multicentre, Randomised, Open-label, Noninferiority Trial.

OBJECTIVE: Mild AD can be treated safely and effectively on an outpatient basis without antibiotics. SUMMARY OF BACKGROUND DATA: In recent years, it has shown no benefit of antibiotics in the treatment of uncomplicated AD in hospitalized patients. Also, outpatient treatment of uncomplicated AD has been shown to be safe and effective. METHODS: A Prospective, multicentre, open-label, noninferiority, randomized controlled trial, in 15 hospitals of patients consulting the emergency department with symptoms compatible with AD.The Participants were patients with mild AD diagnosed by Computed Tomography meeting the inclusion criteria were randomly assigned to control arm (ATB-Group): classical treatment (875/125 mg/8 h amoxicillin/clavulanic acid apart from anti-inflammatory and symptomatic treatment) or experimental arm (Non-ATB-Group): experimental treatment (antiinflammatory and symptomatic treatment). Clinical controls were performed at 2, 7, 30, and 90 days.The primary endpoint was hospital admission. Secondary endpoints included number of emergency department revisits, pain control and emergency surgery in the different arms. RESULTS: Four hundred and eighty patients meeting the inclusion criteria were randomly assigned to Non-ATB-Group (n = 242) or ATB-Group (n = 238). Hospitalization rates were: ATB-Group 14/238 (5.8%) and Non-ATB-Group 8/242 (3.3%) [mean difference 2.58%, 95% confidence interval (CI) 6.32 to -1.17], confirming noninferiority margin. Revisits: ATB-Group 16/238 (6.7%) and Non-ATB-Group 17/242 (7%) (mean difference -0.3, 95% CI 4.22 to -4.83). Poor pain control at 2 days follow up: ATB-Group 13/230 (5.7%), Non-ATB-Group 5/221 (2.3%) (mean difference 3.39, 95% CI 6.96 to -0.18). CONCLUSIONS: Nonantibiotic outpatient treatment of mild AD is safe and effective and is not inferior to current standard treatment.

Aplicación del Shock Index como predictor de hemorragia en el paciente politraumático / The use of the Shock Index as a predictor of active bleeding in trauma patients

INTRODUCCIÓN: Las constantes vitales detectan la presencia de hemorragia al perder grandes cantidades de sangre, lo que comporta una gran morbimortalidad. El Shock Index (SI) es un parámetro que detecta el sangrado con puntos de corte de 0,9. El objetivo de este estudio es valorar si un punto de corte de ≥ 0,8 es más sensible para detectar sangrado oculto, permitiendo iniciar maniobras terapéuticas más precoces. MÉTODOS: Estudio analítico de validación del SI que incluye pacientes politraumatizados graves mayores de 16 años. Se registran constantes vitales y escalas predictivas de sangrado: SI, Assessment of Blood Consumption score y Pulse Rate Over Pressure score. Se analiza la relación del SI con 5 marcadores predictivos de sangrado: necesidad de transfusión masiva, embolización angiográfica, control del sangrado quirúrgico, muerte por shock hipovolémico y "sangrado activo" (presencia de al menos uno de los 4 marcadores anteriores en un paciente). RESULTADOS: Recogida prospectiva de datos de 1.402 pacientes politraumatizados durante 10 años. El Injury Severity Score medio fue de 20,9 (DE 15,8). Hubo una mortalidad del 10%. El SI medio fue de 0,73 (DE 0,29). En total presentaron "sangrado activo" el 18,7% de la serie. El SI medio en los pacientes con "sangrado activo" fue de 0,87, mientras que las constantes vitales estaban dentro de la normalidad. El área bajo la curva ROC del SI para el "sangrado activo" fue de 0,749. CONCLUSIONES: El SI con un punto de corte ≥ 0,8 es más sensible que aquel con el punto de corte ≥ 0,9 y permite iniciar maniobras de reanimación más precoces en los pacientes con sangrado oculto

INTRODUCTION: Vital signs indicate the presence of bleeding only after large amounts of blood have been lost, with high morbidity and mortality. The Shock Index (SI) is a hemorrhage indicator with a cut-off point for the risk of bleeding at 0.9. The aim of this study is to assess whether a cut-off of ≥ 0.8 is more sensitive for detecting occult bleeding, providing for early initiation of therapeutic maneuvers. METHODS: SI analytical validation study of severe trauma patients older than 16 years of age. Vital signs were recorded, and scales for predicting bleeding included: SI, Assessment of Blood Consumption score, and Pulse Rate Over Pressure score. The relationship between the SI and 5 markers for bleeding was analyzed: need for massive transfusion, angiographic embolization, surgical bleeding control, death due to hypovolemic shock, and the overall predictor "active bleeding" (defined as the presence of at least one of the 4 markers above). RESULTS: Data from 1.402 trauma patients were collected prospectively over a period of 10 years. The mean Injury Severity Score was 20.9 (SD 15.8). The mortality rate was 10%. The mean SI was 0.73 (SD 0.29). "Active bleeding" was present in 18.7% of patients. The SI area under the ROC curve for "active bleeding" was 0.749. CONCLUSIONS: An SI cut-off point ≥ 0.8 is more sensitive than ≥ 0.9 and allows for earlier initiation of resuscitation maneuvers in patients with occult active bleeding

Early discharge in Mild Acute Pancreatitis. Is it possible? Observational prospective study in a tertiary-level hospital.

BACKGROUND AND AIMS: In acute pancreatitis (AP), first 24 h are crucial as this is the period in which the greatest amount of patients presents an organ failure. This suggests patients with Mild AP (MAP) could be early identified and discharged. This is an observational prospective trial with the aim to demonstrate the safety of early discharge in Mild Acute Pancreatitis (MAP). METHODS: Observational prospective study in a third level single centre. Consecutive patients with AP from March 2012 to March 2014 were collected. INCLUSION CRITERIA: MAP, tolerance to oral intake, control of pain, C Reactive Protein <150 mg/dL and blood ureic nitrogen < 5 mg/dL in two samples. EXCLUSION CRITERIA: pregnant, lack of family support, active comorbidities, temperature and serum bilirubin elevation. Patients with MAP, who met the inclusion criteria, were discharged within the first 48 h. Readmissions within first week and first 30 days were recorded. Adverse effects related to readmissions were also collected. RESULTS: Three hundred and seventeen episodes were collected of whom 250 patients were diagnosed with MAP. From these, 105 were early discharged. Early discharged patients presented a 30-day readmission rate of 15.2% (16 patients out of 105) corresponding to the readmission rates in Acute Pancreatitis published to date. Any patient presented adverse effects related to readmissions. CONCLUSION: Early discharge in accurately selected patients with MAP is feasible, safe and efficient and leads to a decrease in median stay with the ensuing savings per process and with no increase in readmissions or inmorbi-mortality.

Desarrollo y estudio piloto de un conjunto esencial de indicadores para los servicios de cirugía general / Development and pilot study of an essential set of indicators for general surgery services

INTRODUCCIÓN: En la actualidad no se dispone de un conjunto adecuado de indicadores para benchmarking en las unidades de cirugía general del Sistema Nacional de Salud. Este trabajo presenta la selección, el desarrollo y los resultados del estudio piloto de un primer grupo de indicadores para esta finalidad. MÉTODOS: Se realizó una selección y priorización de indicadores mediante un Delphi modificado con un grupo de expertos de la Asociación Española de Cirujanos. Los indicadores priorizados fueron sometidos a un estudio cualitativo de factibilidad y, para aquellos medidos por historia clínica, cuali-cuantitativo de fiabilidad en un hospital público. Se obtuvieron resultados de concordancia simple y estadístico kappa, ajustado y no ajustado por prevalencias y sesgos, para 3 evaluadores con un muestreo aleatorio sistemático de 30 casos por indicador. RESULTADOS: De los 13 indicadores propuestos, 12 resultaron factibles (5 de historia clínica y 7 de bases de datos). De los 5 de historia, 3 resultaron fiables (concordancia interobservador > 95% o índice kappa > 0,6 para compuestos y subindicadores, o bien kappa ajustado por prevalencias y sesgos > 0,6 en presencia de prevalencias extremas) y 2 necesitaron ser redefinidos a partir de los resultados obtenidos. CONCLUSIONES: Los 5 indicadores de historia clínica podrán utilizarse para comparar unidades quirúrgicas, mientras que los 7 indicadores factibles de bases de datos necesitarán mayor validación y ajuste de riesgo para permitir comparaciones entre servicios. Los resultados del centro evaluado muestran áreas de mejora en algunos procesos de la atención

INTRODUCTION:At present there is a lack of appropriate quality measures for benchmarking in general surgery units of Spanish National Health System. The aim of this study is to present the selection, development and pilot-testing of an initial set of surgical quality indicators for this purpose. METHODS: A modified Delphi was performed with experts from the Spanish Surgeons Association in order to prioritize previously selected indicators. Then, a pilot study was carried out in a public hospital encompassing qualitative analysis of feasibility for prioritized indicators and an additional qualitative and quantitative three-rater reliability assessment for medical record-based indicators. Observed inter-rater agreement, prevalence adjusted and bias adjusted kappa and non-adjusted kappa were performed, using a systematic random sample (n = 30) for each of these indicators. RESULTS: Twelve out of 13 proposed indicators were feasible: 5 medical record-based indicators and 7 indicators based on administrative databases. From medical record-based indicators, 3 were reliable (observed agreement > 95%, adjusted kappa index > 0.6 or non adjusted kappa index > 0.6 for composites and its components) and 2 needed further refinement. CONCLUSIONS: Currently, medical record-based indicators could be used for comparison purposes, whilst further research must be done for validation and risk-adjustment of outcome indicators from administrative databases. Compliance results in the adequacy of informed consent, diagnosis-to-treatment delay in colorectal cancer, and antibiotic prophylaxis show room for improvement in the pilot-tested hospital

Cómo afecta el retraso de la colecistectomía tras la pancreatitis aguda litiásicaen la aparición de recidivas. Consecuencias de la falta de recursos / Influence of delayed cholecystectomy after acute gallstone pancreatitis on recurrence. Consequences of lack of resources

Introducción: la pancreatitis aguda es una enfermedad con tendencia a recurrir, sobre todo si persiste la causa que la desencadena. Nuestro objetivo es determinar la tasa de recurrencia de la pancreatitis aguda biliar tras un primer episodio y su intervalo de aparición, así como identificar los factores de riesgo de recidiva. Material y método: hemos incluido todos los pacientes ingresados por un primer episodio de pancreatitis aguda de origen litiásico durante cuatro años. Las variables principales estudiadas fueron reingreso por recurrencia e intervalo de tiempo de aparición del nuevo episodio. Resultados: hemos incluido 296 pacientes que han ingresado en un total de 386 ocasiones. La incidencia de la pancreatitis aguda biliar en nuestro medio es de 17,5/100.000 habitantes/año. El 19,6% de las pancreatitis han sido graves (22,6% de pancreatitis agudas graves en el primer episodio vs. 3,6% en las pancreatitis recurrentes) con una mortalidad global del 4,4%. La tasa global de recurrencia ha sido del 15,5%, con un intervalo de tiempo de 82 días de mediana. El 14,2% de los pacientes han presentado recurrencia después de un episodio de pancreatitis sin que se les hubiera realizado colecistectomía o colangio-pancreatografía retrógrada endoscópica. Las pancreatitis agudas graves recurren un 7,2% mientras que las leves lo hacen el 16,3%, siendo este el único factor de riesgo de recurrencia hallado. Conclusiones: los pacientes ingresados por pancreatitis deberían ser colecistectomizados a la mayor brevedad posible o ser priorizados en la lista de espera. En su defecto, una alternativa a la cirugía podría ser la colangio-pancreatografía retrógrada endoscópica con esfinterotomía en casos seleccionados (AU)

Introduction: Acute pancreatitis is often a relapsing condition, particularly when its triggering factor persists. Our goal is to determine the recurrence rate of acute biliary pancreatitis after an initial episode, and the time to relapse, as well as to identify the risk factors for recurrence. Material and method: We included all patients admitted for a first acute gallstone pancreatitis event during four years. Primary endpoints included readmission for recurrence and time to relapse. Results: We included 296 patients admitted on a total of 386 occasions. The incidence of acute biliary pancreatitis in our setting is 17.5/100,000 population/year. In all, 19.6% of pancreatitis were severe (22.6% of severe acute pancreatitis for first episodes versus 3.6% for recurring pancreatitis), with an overall mortality of 4.4%. Overall recurrence rate was 15.5%, with a median time to relapse of 82 days. In total, 14.2% of patients relapsed after an acute pancreatitis event without cholecystectomy or endoscopic retrograde cholangio-pancreatography. Severe acute pancreatitis recur in 7.2% of patients, whereas mild cases do so in 16.3%, this being the only risk factor for recurrence thus far identified. Conclusions: Patients admitted for pancreatitis should undergo cholecystectomy as soon as possible or be guaranteed priority on the waiting list. Otherwise, endoscopic retrograde cholangio-pancreatography with sphincterotomy may be an alternative to surgery for selected patients (AU)

Influence of delayed cholecystectomy after acute gallstone pancreatitis on recurrence. Consequences of lack of resources.

INTRODUCTION: Acute pancreatitis is often a relapsing condition, particularly when its triggering factor persists. Our goal is to determine the recurrence rate of acute biliary pancreatitis after an initial episode, and the time to relapse, as well as to identify the risk factors for recurrence. MATERIAL AND METHOD: We included all patients admitted for a first acute gallstone pancreatitis event during four years. Primary endpoints included readmission for recurrence and time to relapse. RESULTS: We included 296 patients admitted on a total of 386 occasions. The incidence of acute biliary pancreatitis in our setting is 17.5/100,000 population/year. In all, 19.6% of pancreatitis were severe (22.6% of severe acute pancreatitis for first episodes versus 3.6% for recurring pancreatitis), with an overall mortality of 4.4%. Overall recurrence rate was 15.5%, with a median time to relapse of 82 days. In total, 14.2% of patients relapsed after an acute pancreatitis event without cholecystectomy or endoscopic retrograde cholangio-pancreatography. Severe acute pancreatitis recur in 7.2% of patients, whereas mild cases do so in 16.3%, this being the only risk factor for recurrence thus far identified. CONCLUSIONS: Patients admitted for pancreatitis should undergo cholecystectomy as soon as possible or be guaranteed priority on the waiting list. Otherwise, endoscopic retrograde cholangio-pancreatography with sphincterotomy may be an alternative to surgery for selected patients.

Registro prospectivo en politraumatismos graves. Análisis de 1.200 pacientes / Prospective registry of severe polytrauma. Analysis of 1200 patients

INTRODUCCIÓN: El politraumatismo sigue siendo una de las principales causas de muerte entre los 10 y los 40 años, causando graves incapacidades en los pacientes que sobreviven. El objetivo de nuestro estudio es realizar un análisis de calidad de la atención del paciente politraumatizado mediante un estudio epidemiológico. MÉTODO: Registro prospectivo de todos los pacientes politraumáticos atendidos en nuestro hospital, mayores de 16 años, que ingresan en el área de críticos o mueren antes del ingreso. RESULTADOS: Desde marzo del 2006 hasta agosto del 2014, registramos 1.200 politraumatizados. La mayoría fueron hombres (75%), con una mediana de edad de 45 años. El ISS medio fue de 20,9 ± 15,8 y el mecanismo de acción más frecuente fue cerrado (94% casos). La mortalidad global fue del 9,8% (117 casos), siendo la muerte neurológica la principal causa de fallecimiento (45,3%), seguida de la muerte por shock hipovolémico (29,1%). En 17 casos (14,5% fallecimiento) la mortalidad fue considerada como evitable o potencialmente evitable un total de 327 pacientes (27,3%) precisaron de tratamiento quirúrgico urgente y 106 pacientes (8,8%) precisaron de un tratamiento mediante radiología intervencionista de carácter urgente. El 18,5% de los pacientes (222) presentaron alguna lesión inadvertida, con un total de 318 lesiones inadvertidas. CONCLUSIÓN: La atención ofrecida en nuestro centro es correcta. La necesidad de una recogida de datos prospectiva de la atención global a los pacientes politraumatizados es necesaria e imprescindible para poder evaluar la calidad ofrecida y mejorar los resultados

INTRODUCTION: Polytrauma continues to be one of the main causes of death in the population between 10-40 years of age, and causes severe discapability in surviving patients. The aim of this study is to perform an analysis of the quality of care of the polytrauma patient using an epidemiological study. METHOD: Prospective registry of all polytrauma patients treated at our hospital over 16 years of age, admitted to the critical care area or dead before admission. RESULTS: From March 2006 to August 2014, we registered 1200 polytrauma patients. The majority were men (75%) with a median age of 45. The mean ISS was 20,9 ± 15,8 and the most common mechanism of injury was blunt trauma (94% cases), The global mortality rate was 9.8% (117 cases), and neurological death was the most frequent cause (45.3%), followed by hypovolemic shock (29,1%). In 17 cases (14,5% of deaths) mortality was considered evitable or potentially evitable, A total of 327 patients (27.3%) needed emergency surgery and 106 patients (8,8%) needed emergency treatment using interventional radiology. 18,5% of patients (222) presented an inadverted injury, with a total of 318 inadverted injuries. CONCLUSION: Trauma care at our centre is adequate. A prospective registry of the global care of polytrauma patients is necessary to evaluate the quality of care and improve results
