RESUMO

Objetivo: Evaluar la eficacia, seguridad y resultados clínicos y oncológicos del stent colónico en la estrategia terapéutica inicial de la obstrucción intestinal por cáncer de colon izquierdo. Métodos: Estudio descriptivo y ambispectivo (2008-2018) de pacientes con diagnóstico clínico y radiológico de obstrucción neoplásica de colon izquierdo en los que se indicó colocación de stent, analizando los grupos de stent paliativo, stent como puente a cirugía y cirugía urgente por fallo o complicaciones del stent. Resultados: El estudio incluyó a 208 pacientes. La tasa de éxito técnico y clínico fue del 82,2 y del 74,5%, respectivamente, con perforación asociada en el 4,3% de la muestra. En el 32,2% el stent se comportó como puente a cirugía, mientras que el 28,4% de los pacientes precisaron intervención quirúrgica urgente. En el 39,4% el stent fue colocado con intención paliativa. La proporción de cirugía laparoscópica, resección oncológica, anastomosis primaria y ganglios obtenidos fue superior en los pacientes intervenidos mediante cirugía electiva frente a la urgente, con menor estancia postoperatoria y orbimortalidad postoperatoria grave. Los pacientes en estadio II-III con resección tumoral oncológica intervenidos de forma programada presentaron mayor supervivencia que aquellos intervenidos de urgencia (p = 0,001). Conclusiones: El tratamiento de la oclusión neoplásica de colon izquierdo mediante stent supone una estrategia eficaz para operar de forma electiva un número importante de pacientes y evita la colostomía en pacientes paliativos, aunque las complicaciones o el fracaso de la técnica conllevan cirugía urgente en casi un tercio de los pacientes


Objective: To evaluate the efficacy, safety and clinical and oncological results of colonic stents in the initial therapeutic strategy of obstructive left colon cancer. Methods: Descriptive and ambispective study (2008-2018) of patients with clinical and radiological diagnosis of neoplastic obstruction of the left colon in whom a colonic stent was indicated, analyzing the following groups: palliative stent, stent as bridge to surgery and urgent surgery in case of stent failure or complications. Results: The study included 208 patients. The technical and clinical success rates were 82.2% and 74.5%, respectively, with associated perforation in 4.3% of the sample. In 32.2%, the stent was placed as bridge to surgery, while 28.4% required urgent surgical intervention. The stent was placed with palliative intent in 39.4%. The proportion of laparoscopic surgery, oncological resection, primary anastomosis and lymph nodes resected were higher in patients undergoing elective surgery than in urgent surgery, with shorter postoperative stay and less severe postoperative morbidity and mortality. Stage II-III patients with oncological tumor resection who underwent elective surgery had increased survival compared to those who underwent urgent surgery (P = 0.001). Conclusions: Initial treatment of neoplastic obstruction of the left colon with a stent is an effective strategy in elective surgery and avoids permanent colostomy in palliative patients, although complications or stent failure lead to urgent surgery in almost one-third of patients

RESUMO

Los reingresos urgentes suponen un impacto importante sobre los resultados en la salud de los pacientes y los costes sanitarios. Los factores de riesgo asociados a reingreso tras cirugía de resección pulmonar han sido poco estudiados. El principal objetivo del presente trabajo es la identificación de factores pre- y perioperatorios determinantes de reingreso; secundariamente, determinación de tasa de reingresos, identificación de diagnósticos de reingreso, e impacto de los reingresos sobre las tasas de supervivencia en los estudios que lo analizaban. La revisión se realizó mediante búsqueda sistemática en las principales bases de datos bibliográficas. Finalmente, 19 trabajos cumplieron los criterios de selección. Los principales factores de riesgo fueron: variables sociodemográficas de los pacientes; comorbilidades; tipo de resección; complicaciones postoperatorias; estancia prolongada. A pesar de la gran variabilidad en los estudios publicados, todos destacan la importancia de reducir los índices de reingreso por su significativo impacto sobre pacientes y sistema sanitario

The review was performed through a systematic search in the main bibliographic databases. In the end, 19 papers met the selection criteria. The main risk factors were: sociodemographic patient variables; comorbidities; type of resection; postoperative complications; long stay. Despite the great variability in the published studies, all highlight the importance of reducing readmission rates because of the significant impact on patients and the healthcare system

RESUMO

Objetivo. Conocer la epidemiología y distribución de los traumatismos abdominales en nuestro medio. Evaluar el comportamiento y fiabilidad de la aplicación de índices pronósticos de gravedad analizando su correlación con las decisiones terapéuticas y los resultados obtenidos Método. Estudio retrospectivo en el que se han incluido todos los pacientes con diagnóstico de traumatismo abdominal grave ingresados en un hospital español de referencia, entre 2009 y 2015. Se registraron variables epidemiológicas, clínicas y de resultados, así como la puntuación de distintos índices pronósticos. Resultados. Muestra 153 pacientes, con mediana de edad de 38 años y predominio masculino (73,9%). Correspondieron a traumatismos de tipo cerrado (94,1%) y su etiología principal los accidentes de tráfico (60,1%). El bazo fue el órgano más frecuentemente afectado (44,4%), seguido por el hígado (36,6%). La mediana de la estancia hospitalaria fue de 11 días y la mortalidad global de 13%. Aunque el 62,7% se manejó con éxito de forma conservadora, se observó una mayor puntuación de Injury Severity Score (ISS) y Trauma and Injury Severity Score (TRISS) en aquellos pacientes que precisaron tratamiento quirúrgico (p = 0,0001), en los que fallecieron (p = 0,0001) y en aquellos con mayor estancia hospitalaria (RTS -Reevised Trauma Score- p = 0,001 y TRISS p = 0,016). Conclusiones. La etiología de los traumatismos abdominales y los balances lesionales en nuestro medio fueron similares a los observados a nivel nacional. La puntuación en las escalas estudiadas tuvo una asociación directa con la necesidad de tratamiento quirúrgico, los días de estancia hospitalaria, la morbilidad y la mortalidad


Objectives. To describe the abdominal injuries treated in our hospital. We assessed the behavior and reliability of prognostic scales, analyzing the correlations between them and therapeutic decisions and outcomes. Methods. Retrospective study including all patients with major abdominal injuries admitted to our hospital between 2009 and 2015. We gathered epidemiologic and clinical data, outcomes, and scores on several prognostic scales. Results. The median age of the 153 patients we identified from case records was 38 years; 73.9% were males. Most cases involved blunt trauma (94.1%) sustained in traffic accidents (60.1%). The spleen and the liver were the organs most often affected (in 44.4% and 36.6%, respectively). The median length of stay in the hospital was 11 days, and overall mortality was 13%. Although conservative management was successful in 62.7% of the cases, we found that patients who had a higher ISS (Injury Severity Score) or TRISS (Trauma and Injury Severity Score) assessments more often required surgery or died (P=.0001, both comparisons). Those who had longer hospital stays had a higher Revised Trauma Score or TRISS (P=.001 and P=.016, respectively). Conclusions. The causes of abdominal injuries and the types treated in our hospital were similar to those described for the rest of Spain. Punctuation on prognostic severity scales correlated directly with the need for surgery, length of hospital stay, complications, and mortality

RESUMO

Introducción: La reconstrucción mamaria tras mastectomía ha demostrado tener un impacto psicosocial muy importante en las pacientes. Existen 2 grandes grupos de técnicas reconstructivas: la reconstrucción con implantes y la reconstrucción con tejido autógeno de la paciente. Para poder realizar una valoración más objetiva de los resultados es importante conocer la satisfacción que presentan las mismas, por lo que se decide realizar un estudio empleando el Q-BREAST cuyo objetivo es analizar la satisfacción de las pacientes mastectomizadas en función de las diferentes técnicas quirúrgicas de reconstrucción. Métodos: Se realiza un estudio retrospectivo, descriptivo y observacional de las pacientes reconstruidas en nuestro servicio del 2008 al 2011. Se comparan los niveles de satisfacción de las pacientes según la técnica quirúrgica empleada en la reconstrucción de mama mediante el empleo del test Q-BREAST, que se les envió por correo. Resultados: Se obtiene una respuesta al Q-BREAST de 90 pacientes. No se encuentran diferencias estadísticas en los niveles de satisfacción en relación con la edad, el tipo de mastectomía realizada, el tratamiento coadyuvante y la existencia de complicaciones. Sí se observan unos niveles superiores de satisfacción en las pacientes reconstruidas con tejido autógeno frente a los implantes (p = 0,028). Conclusiones: Las pacientes reconstruidas con tejido autógeno presentan niveles más altos de satisfacción que las reconstruidas con implantes (AU)


Background: It has been proved that a breast reconstruction after a mastectomy has a great psycho-social impact on patients. For this reason, it is increasingly done in a greater percentage of cases. There are two major groups of reconstructive techniques: a reconstruction with implants and a reconstruction with autologous tissue of the patient. In order to make a more objective assessment of the results, it is important to know how satisfied these patients are with the results. Therefore, we performed a study using Q-BREAST, the aim of which is to analyze the satisfaction of mastectomized patients according to the different surgical reconstruction techniques. Methods: A retrospective, descriptive and observational study of patients reconstructed in our service from 2008 to 2011 was carried out. Patient satisfaction levels were compared according to the surgical technique used in breast reconstruction using the Q-BREAST test, which was mailed to them. Results: There are no statistical differences in the levels of satisfaction in terms of age, type of mastectomy done, coadjutant treatment or existence of complications. Higher levels of satisfaction are observed in patients reconstructed with autologous tissue versus implants (P = .028). Conclusions: Patients reconstructed with autologous tissue have higher levels of satisfaction than those reconstructed with implants (AU)

RESUMO

Objetivo: Establecer la tasa de apendicectomía negativa (TAN) y evaluar las diferencias entre la Escala de Alvarado y la ecografía abdominal en los pacientes con apendicitis aguda (AA) y aquellos con apendicectomía negativa. Método: Estudio descriptivo, retrospectivo de corte transversal. Se recogieron los pacientes intervenidos de urgencia bajo sospecha de AA durante un año en un hospital de tercer nivel. Resultados: Se incluyeron 225 pacientes. La TAN fue de 7,11%. Una puntuación en la Escala de Alvarado mayor o igual de 5 obtuvo una odds ratio (OR) de 7,46 (p = 0,0002) para padecer AA, con una sensibilidad del 94,2%. La ecografía compatible con AA obtuvo una OR 3,58 (p = 0,0125) y una TAN del 5%. Conclusiones: La elevada sensibilidad de la Escala de Alvarado para puntuación mayor o igual de 5 hace aconsejable su aplicación en todo paciente que acude al Servicio de Urgencias con dolor en la fosa iliaca derecha. Puntuaciones mayores o iguales a 7 disminuyen la TAN hasta el 3%. La ecografía abdominal es una prueba rápida y barata con una TAN baja (AU)


Objective: To establish the negative appendectomy rate (NAR) after patients with acute abdomen were evaluated with the Alvarado score and compare it to the NAR in patients evaluated with abdominal ultrasound. Methods: Cross-sectional, retrospective, descriptive study in patients who underwent emergency surgery for suspected acute appendicitis in a tertiary-care hospital over a period of 1 year. Results: A total of 225 patients were included. The NAR was 7.11% for the series. An Alvarado score of 5 or more had an odds ratio (OR) of 7.46 (P=.0002) for acute appendicitis; sensitivity was 94.2%. Ultrasound findings consistent with acute appendicitis had an OR of 3.58 (P=.0125) for the diagnosis; the NAR was 5%. Conclusions: The high sensitivity of an Alvarado score of 5 or more supports using this tool to evaluate all patients who come to the emergency department with pain in the right iliac fossa. With scores of 7 or more the NAR falls to 3%. Abdominal ultrasound is a rapid, inexpensive diagnostic procedure associated with a low NAR (AU)
