INDURG TRIAL PROTOCOL: A RANDOMIZED CONTROLLED TRIAL USING INDOCYANINE GREEN DURING CHOLECYSTECTOMY IN ACUTE CHOLECYSTITIS.

INTRODUCTION: Laparoscopic cholecystectomy is one of the most common gastrointestinal surgeries, and bile duct injury is one of its main complications. The use of real-time indocyanine green fluorescence cholangiography allows the identification of extrahepatic biliary structures, facilitating the procedure and reducing the risk of bile duct lesions. A better visualization of the bile duct may help to reduce the need for conversion to open surgery, and may also shorten operating time. The main objective of this study is to determine whether the use of indocyanine green is associated with a reduction in operating time in emergency cholecystectomies. Secondary outcomes are the postoperative hospital stay, the correct intraoperative visualization of the Calot's Triangle structures with the administration of indocyanine green, and the intraoperative complications, postoperative complications and morbidity according to the Clavien-Dindo classification. METHODS: This is a randomized, prospective, controlled, multicenter trial with patients diagnosed with acute cholecystitis requiring emergency cholecystectomy. The control group will comprise 220 patients undergoing emergency laparoscopic cholecystectomy applying the standard technique. The intervention group will comprise 220 patients also undergoing emergency laparoscopic cholecystectomy for acute cholecystitis with prior administration of indocyanine green. CONCLUSION: Due to the lack of published studies on ICG in emergency laparoscopic cholecystectomy, this study may help to establish procedures for its use in the emergency setting.

Resultados del Registro Nacional de Politraumatismos español ¿Dónde estamos y a dónde nos dirigimos? / Results of the Spanish National Polytrauma Registry. Where are we and where are we heading?

Introducción: En 2017 se emprendió el Registro Nacional de Politraumatismos (RNP) a nivel estatal español, cuya finalidad residía en mejorar la calidad de la atención al paciente politraumatizado grave y evaluar el uso de recursos y estrategias de tratamiento. El objetivo de este trabajo es presentar los datos recogidos en el RNP hasta la actualidad. Métodos: Estudio observacional retrospectivo a partir de los datos recogidos prospectivamente en el RNP. Se incluyen pacientes mayores de 14 años, con ISS≥15 o mecanismo de trauma penetrante, atendidos en 17 hospitales de tercer nivel de España. Resultados: Del 1/1/17 al 1/1/22 se han registrado un total de 2.069 pacientes politraumatizados. El 76,4% son varones; edad media: 45 años; ISS medio: 22,8 y mortalidad: 10,2%. El mecanismo de lesión más frecuente es el cerrado (80%) con mayor incidencia de accidentes de moto (23%). Un 12% de los pacientes sufren un traumatismo penetrante, por arma blanca en el 84%. Un 16% de los pacientes ingresa hemodinámicamente inestable en el hospital. Activando el protocolo de transfusión masiva en el 14% de los pacientes e interviniendo quirúrgicamente a un 53%. La estancia hospitalaria mediana es de 11 días. Precisando ingreso en la UCI un 73,4% (estancia media: 5 días). Conclusiones: Los pacientes politraumatizados registrados en el RNP son mayoritariamente varones de mediana edad, que sufren traumatismos cerrados y presentan una elevada incidencia de lesiones torácicas. La detección y el tratamiento dirigido de este tipo de lesiones probablemente permitirá mejorar la calidad asistencial del politraumatizado en nuestro medio. (AU)

Introduction: In 2017 the Spanish National Polytrauma Registry (SNPR) was initiated in Spain, its goal was to improve the quality of severe trauma management and evaluate the use of resources and treatment strategies. The objective of this study is to present the information obtained with the SNPR since it was initiated. Methods: Observational study with prospective data collection from the SNPR. Trauma patients included are older than 14 yeas, with ISS ≥ 15 or penetrating mechanism. In total 17 hospitals from Spain have participated. Results: From 1/1/17 to 1/1/22, 2069 trauma patients were registered. The majority were men (76.4%); mean age: 45 years; mean ISS: 22.8 and mortality: 10.2%. The most common mechanism of injury was blunt trauma (80%), being motorbike accident the most frequent (23%). Penetrating trauma is presented in 12% of patients, being stab wound the most common (84%). Sixteen percent of patients are hemodynamically unstable on hospital arrival. Massive transfusion protocol is activated in 14% of patients and 53% are operated. Median hospital stay is 11 days. There is a 73.4% of patients who need intensive care unit (ICU) admission, with a median ICU stay of 5 days. Conclusions: Trauma patients registered in the SNPR are predominantly middle-aged males who experience blunt trauma with a high incidence of thoracic injuries. Early and addressed detection of these kind of injuries would probably improve trauma quality of care in our environment. (AU)

INTRODUCTION: In 2017, the Spanish National Polytrauma Registry (SNPR) was initiated in Spain with the goal to improve the quality of severe trauma management and evaluate the use of resources and treatment strategies. The objective of this study is to present the data obtained with the SNPR since its inception. METHODS: We conducted an observational study with prospective data collection from the SNPR. The trauma patients included were over 14 years of age, with ISS ≥ 15 or penetrating mechanism of injury, from a total of 17 tertiary hospitals in Spain. RESULTS: From 1/1/17 to 1/1/22, 2069 trauma patients were registered. The majority were men (76.4%), with a mean age of 45 years, mean ISS 22.8, and mortality 10.2%. The most common mechanism of injury was blunt trauma (80%), the most frequent being motorcycle accident (23%). Penetrating trauma was presented in 12% of patients, stab wounds being the most common (84%). On hospital arrival, 16% of patients were hemodynamically unstable. The massive transfusion protocol was activated in 14% of patients, and 53% underwent surgery. Median hospital stay was 11 days, while 73.4% of patients required intensive care unit (ICU) admission, with a median ICU stay of 5 days. CONCLUSIONS: Trauma patients registered in the SNPR are predominantly middle-aged males who experience blunt trauma with a high incidence of thoracic injuries. Early addressed detection and treatment of these kind of injuries would probably improve the quality of trauma care in our environment.

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.

Dynamic use of fibrinogen under viscoelastic assessment results in reduced need for plasma and diminished overall transfusion requirements in severe trauma.

BACKGROUND: Despite advances in trauma management, half of trauma deaths occur secondary to bleeding. Currently, hemostatic resuscitation strategies consist of empirical transfusion of blood products in a predefined fixed ratio (1:1:1) to both treat hemorrhagic shock and correct trauma-induced coagulopathy. At our hospital, the implementation of a resuscitation protocol guided by viscoelastic hemostatic assays (VHAs) with rotational thromboelastometry has resulted in a goal-directed approach. The objective of the study is twofold, first to analyze changes in transfusion practices overtime and second to identify the impact of these changes on coagulation parameters and clinical outcomes. We hypothesized that progressive VHA implementation results in a higher administration of fibrinogen concentrate (FC) and lower use of blood products transfusion, especially plasma. METHODS: A total of 135 severe trauma patients (January 2008 to July 2019), all requiring and initial assessment for high risk of trauma-induced coagulopathy based on high-energy injury mechanism, severity of bleeding and hemodynamic instability were included. After 2011 when we first modified the transfusion protocol, a progressive change in transfusional management occurred over time. Three treatment groups were established, reflecting different stages in the evolution of our strategy: plasma (P, n = 28), plasma and FC (PF, n = 64) and only FC (F, n = 42). RESULTS: There were no significant differences in baseline characteristics among groups. Progressive implementation of rotational thromboelastometry resulted in increased use of FC over time ( p < 0.001). Regression analysis showed that group F had a significant reduction in transfusion of packed red blood cells ( p = 0.005), plasma ( p < 0.001), and platelets ( p = 0.011). Regarding outcomes, F patients had less pneumonia ( p = 0.019) and multiorgan failure ( p < 0.001), without significant differences for other outcomes. Likewise, overall mortality was not significantly different. However, further analysis comparing specific mortality due only to massive hemorrhage in the F group versus all patients receiving plasma, it was significantly lower ( p = 0.037). CONCLUSION: Implementing a VHA-based algorithm resulted in a plasma-free strategy with higher use of FC and a significant reduction of packed red blood cells transfused. In addition, we observed an improvement in outcomes without an increase in thrombotic complications. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

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)

Is Local Resection of Anal Canal Tumors Feasible with Transanal Endoscopic Surgery?

BACKGROUND: An important drawback of local surgery for lesions in the anal canal is the difficulty of achieving en bloc full-thickness resections. The aim of this study is to evaluate TEM/TEO in lesions of this type from the point of view of morbidity, mortality and the quality of the pathology specimen. METHODS: This is an observational study with prospective data collection from June 2004 to July 2018. Two groups are defined: group A (rectal tumors with proximal margin between 0 and ≤4 cm from anal verge) and group B (distal margin > 4 cm from anal verge). A technical description is provided; resections and postoperative complications in both groups are compared. RESULTS: During the study period, 757 patients underwent TEM/TEO. Finally, 692 patients were included, 192 patients in group A and 500 patients in group B. An en bloc surgical specimen was obtained in 176/192 patients (91.7%), although the defect was completely sutured in 132 (68.8%). In the comparative analysis, group A did not present significantly greater fragmentation of the resected piece [16/192 (8.3%) vs. 36/500 (7.2%), p = 0.630], although group A was associated with greater involvement of the surgical margin [28/192 (14.6%), 32/500 (6.4%), p = 0.001] and clinically relevant morbidity [16/192 (8.3%), 20/500 (4%), p = 0.034]. There was no mortality. CONCLUSIONS: The use of TEM/TEO to remove lesions originating in the anal canal is feasible. But we have to take into account that there is an increase in complications, technical difficulties and affected margins resection.

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
