Consequences of preoperative cardiac stress testing-A cohort study.

OBJECTIVE: To understand the consequences of functional cardiac stress testing among patients considering noncardiac nonophthalmologic surgery. DESIGN: A retrospective cohort study of 118,552 patients who made 159,795 visits to a dedicated preoperative risk assessment and optimization clinic between 2008 and 2018. SETTING: A large integrated health system. PATIENTS: Patients who visited a dedicated preoperative risk assessment and optimization clinic before noncardiac nonophthalmologic surgery. MEASUREMENTS: To assess changes to care delivered, we measured the probability of completing additional cardiac testing, cardiac surgery, or noncardiac surgery. To assess outcomes, we measured time-to-mortality and total one-year mortality. MAIN RESULTS: In causal inference models, preoperative stress testing was associated with increased likelihood of coronary angiography (relative risk: 8.6, 95% CI 6.1-12.1), increased likelihood of percutaneous coronary intervention (RR: 4.1, 95% CI: 1.8-9.2), increased likelihood of cardiac surgery (RR: 6.8, 95% CI 4.9-9.4), decreased likelihood of noncardiac surgery (RR: 0.77, 95% CI 0.75-0.79), and delayed noncardiac surgery for patients completing noncardiac surgery (mean 28.3 days, 95% CI: 23.1-33.6). The base rate of downstream cardiac testing was low, and absolute risk increases were small. Stress testing was associated with higher mortality in unadjusted analysis but was not associated with mortality in causal inference analyses. CONCLUSIONS: Preoperative cardiac stress testing likely induces coronary angiography and cardiac interventions while decreasing use of noncardiac surgery and delaying surgery for patients who ultimately proceed to noncardiac surgery. Despite changes to processes of care, our results do not support a causal relationship between stress testing and postoperative mortality. Analyses of care cascades should consider care that is avoided or substituted in addition to care that is induced.

Preservation of deep epigastric perforators during anterior component separation technique (ACST) results in equivalent wound complications compared to transversus abdominis release (TAR).

PURPOSE: The use of component separation results in myofascial release and increased rates of fascial closure in abdominal wall reconstruction(AWR). These complex dissections have been associated with increased rates of wound complications with anterior component separation having the greatest wound morbidity. The aim of this paper was to compare the wound complication rate between perforator sparing anterior component separation(PS-ACST) and transversus abdominus release(TAR). METHODS: Patients were identified from a prospective, single institution hernia center database who underwent PS-ACST and TAR from 2015 to 2021. The primary outcome was wound complication rate. Standard statistical methods were used, univariate analysis and multivariable logistic regression were performed. RESULTS: A total of 172 patients met criteria, 39 had PS-ACST and 133 had TAR performed. The PS-ACST and TAR groups were similar in terms of diabetes (15.4% vs 28.6%, p = 0.097), but the PS-ACST group had a greater percentage of smokers (46.2% vs 14.3%, p < 0.001). The PS-ACST group had a larger hernia defect size (375.2 ± 156.7 vs 234.4 ± 126.9cm2, p < 0.001) and more patients who underwent preoperative Botulinum toxin A (BTA) injections (43.6% vs 6.0%, p < 0.001). The overall wound complication rate was not significantly different (23.1% vs 36.1%, p = 0.129) nor was the mesh infection rate (0% vs 1.6%, p = 0.438). Using logistic regression, none of the factors that were significantly different in the univariate analysis were associated with wound complication rate (all p > 0.05). CONCLUSION: PS-ACST and TAR are comparable in terms of wound complication rates. PS-ACST can be used for large hernia defects and promote fascial closure with low overall wound morbidity and perioperative complications.

Association between anaemia and hospital readmissions in patients undergoing major surgery requiring postoperative intensive care.

Anaemia is a common sequela of surgery, although its relationship with patient recovery is unclear. The goal of this investigation was to assess the associations between haemoglobin concentrations at the time of hospital discharge following major surgery and early post-hospitalisation outcomes, with a primary outcome of 30 day unanticipated hospital readmissions. This investigation includes data from two independent population-based observational cohorts of adult surgical patients (aged ≥ 18 years) requiring postoperative intensive care unit admission between 1 January 2010 and 31 December 2019 in hospitals in Olmsted County, Minnesota, and between 1 July 2010 and 30 June 2017 in the Kaiser Permanente Northern California integrated healthcare system, California. Cox proportional hazards models assessed the associations between discharge haemoglobin concentrations (per 10 g.l-1 ) and outcomes, with prespecified multivariable adjustment. A total of 3260 patients were included from Olmsted County hospitals and 29,452 from Kaiser Permanente Northern California. In adjusted analyses, each 10 g.l-1 decrease in haemoglobin at hospital discharge was associated with a 9% (hazard ratio 1.09, 95%CI 1.02-1.18; p = 0.014) and 8% increase (hazard ratio 1.08, 95%CI 1.06-1.11; p < 0.001) in the hazard for readmission within 30 days in Olmsted County and Kaiser Permanente Northern California, respectively. In a sensitivity analysis exploring relationships across varying levels of pre-operative anaemia severity, these associations remained consistent, with lower discharge haemoglobin concentrations associated with higher readmissions irrespective of pre-operative anaemia severity. Anaemia at hospital discharge in surgical patients requiring postoperative intensive care is associated with increased rates of hospital readmission in two large independent cohorts. Future studies are necessary to evaluate strategies to prevent and/or treat anaemia in these patients for the improvement of post-hospitalisation outcomes.

Aplicación tópica de ácido tranexámico en urología: ¿Una alternativa de manejo? / Topical Application of Tranexamic Acid in Urology: An Alternative Management?

Los agentes antifibrinolíticos, como el ácido tranexámico, por medio de su administración endovenosa se usan en distintos procedimientos quirúrgicos para prevenir la pérdida de sangrado perioperatorio.[1] Este medicamento es un derivado sintético análogo de la lisina que bloquea los sititos de unión de la lisina en el plasminógeno, inhibiendo su conversión a plasmina e interfiriendo en la fibrinólisis.[2] La aplicación del ácido tranexámico para disminuir el riesgo de sangrado ha sido utilizado en procedimientos urológicos como la resección transuretral prostática (RTUP), prostatectomía radical y nefrolitotomía percutánea (NLP),[3] [4] [5] también se emplea para disminuir las hematurias persistentes en pacientes con poliquistosis renal y en otras hematurias macroscópicas de origen urológico.

Antifibrinolytic agents, such as tranexamic acid, by intravenous administration are used in various surgical procedures to prevent perioperative bleeding loss.[1] This drug is a synthetic lysine analog derivative that blocks the lysine binding sites on plasminogen, inhibiting its conversion to plasmin and interfering with fibrinolysis.[2] The application of tranexamic acid to reduce the risk of bleeding has been used in urological procedures such as transurethral resection of the prostate (TURP), radical prostatectomy and nephrolithotomy. The application of tranexamic acid to reduce the risk of bleeding has been used in urological procedures such as transurethral resection of the prostate (TURP), radical prostatectomy and percutaneous nephrolithotomy (PNL),[3] [4] [5] it is also used to reduce persistent hematuria in patients with polycystic kidney disease and other macroscopic hematuria of urological origin.

Application of Music Therapy in General Surgical Treatment.

With the increasing application of music therapy in clinical practice, the effectiveness of music therapy in improving the negative emotions of patients, relieving pain, and adjusting the physiological state has also been receiving increasing recognization. Moreover, music therapy as adjuvant therapy for conventional treatment can achieve a better improvement in patient satisfaction and facilitate the acceptance of make music therapy by the medical industry. In addition to inevitable trauma, general surgery is criticized for its long treatment cycles and postoperative pain. With the continuous development of fast-track surgery (FTS), music therapy has received more attention in general surgical treatment. This study reviews the development history and prospects of music therapy in general surgery.

Supplemental findings of the 2019 National Blood Collection and Utilization Survey.

INTRODUCTION: Supplemental data from the 2019 National Blood Collection and Utilization Survey (NBCUS) are presented and include findings on donor characteristics, autologous and directed donations and transfusions, platelets (PLTs), plasma and granulocyte transfusions, pediatric transfusions, transfusion-associated adverse events, cost of blood units, hospital policies and practices, and implementation of blood safety measures, including pathogen reduction technology (PRT). METHODS: National estimates were produced using weighting and imputation methods for a number of donors, donations, donor deferrals, autologous and directed donations and transfusions, PLT and plasma collections and transfusions, a number of crossmatch procedures, a number of units irradiated and leukoreduced, pediatric transfusions, and transfusion-associated adverse events. RESULTS: Between 2017 and 2019, there was a slight decrease in successful donations by 1.1%. Donations by persons aged 16-18 decreased by 10.1% while donations among donors >65 years increased by 10.5%. From 2017 to 2019, the median price paid for blood components by hospitals for leukoreduced red blood cell units, leukoreduced apheresis PLT units, and for fresh frozen plasma units continued to decrease. The rate of life-threatening transfusion-related adverse reactions continued to decrease. Most whole blood/red blood cell units (97%) and PLT units (97%) were leukoreduced. CONCLUSION: Blood donations decreased between 2017 and 2019. Donations from younger donors continued to decline while donations among older donors have steadily increased. Prices paid for blood products by hospitals decreased. Implementation of PRT among blood centers and hospitals is slowly expanding.

Human Cadaveric Artificial Lung Tumor-Mimic Training Model.

Introduction: An important phase in surgical training is gaining experience in real human anatomical situations. When a cadaver is available it may complement the various artificial practice models. However, it is often necessary to supplement the characteristics of the cadavers with a simulation of a tumor. Our objective was to develop an easy-to-create, realistic artificial tumor-mimic model for peripheral lung tumor resection practice. Methods: In our work we injected barium sulphate enriched silicone suspension into 10 isolated, non-fixed lungs of human cadavers, through the puncture of the visceral pleura. Four lesions-apical, hilar and two peripheral-were created in each of ten specimens. After fixation CT scans were obtained and analyzed. The implanted tumor-mimics were examined after anatomical preparation and slicing. Also performed CT-guided percutaneous puncture was also performed to create the lesions in situ in two lungs of human cadavers. Results: Analyzing the CT data of 10 isolated lungs, out of 40 lesions, 34 were nodular (85.0%) and in the nodular group five were spiculated (12.5%). Satellite lesions were formed in two cases (5.0%). Relevant outflow into vessels or airway occurred in five lesions (12.5%). Reaching the surface of the lung occured in 11 lesions (27.5%). The tumor-mimics were elastic and adhered well to the surrounding tissue. The two lesions, implanted via percutaneous puncture, both were nodular and one also showed lobulated features. Conclusion: Our artificial tumor-mimics were easy to create, varied in shape and size, and with percutaneous implantation the lesions provide a model for teaching every step of a surgical procedure.

Resumo Fundamento Houve aumento expressivo na incidência de infecções relacionadas a dispositivos cardíacos eletrônicos implantáveis (DCEI) nos últimos anos, com impacto na mortalidade. Objetivos Verificar a proporção de pacientes com infecção de DCEI e analisar seu perfil clínico, as variáveis relacionadas com a infecção e sua evolução. Método Estudo retrospectivo, observacional e longitudinal com 123 pacientes com infecção de DCEI entre 6.406 procedimentos. Foram usados os testes paramétricos, e o nível de significância adotado na análise estatística foi de 5%. Resultados A idade média dos pacientes foi de 60,1 anos, e 71 eram homens. A média de internação foi de 35,3 dias, e houve remoção total do sistema em 105 pacientes. Identificaram-se endocardite infecciosa (EI) e sepse em 71 e 23 pacientes, respectivamente. A mortalidade intra-hospitalar foi 19,5%. Houve associação entre EI e extrusão do gerador (17,0% vs. 19,5% nos grupos com e sem EI, respectivamente, p = 0,04; associação inversa) e sepse (15,4% vs. 3,2%, p = 0,01). Houve associação entre morte intra-hospitalar e EI (83,3% vs. 52,0% com e sem morte, respectivamente, p = 0,005) e sepse (62,5% vs. 8,1%, p < 0,0001). Foi dada alta hospitalar a 99 pacientes. Durante a média de seguimento clínico de 43,8 meses, a taxa de mortalidade foi de 43%, e 65,2% dos pacientes com sepse faleceram (p < 0,0001). A curva de sobrevida de Kaplan-Meier não indicou associação significante com sexo, agente etiológico, fração de ejeção, EI e modalidade de tratamento. A taxa de mortalidade foi de 32,8% entre os pacientes submetidos a reimplante de eletrodos por via endocárdica e 52,2% entre aqueles por via epicárdica (p = 0,04). Não houve influência da etiologia chagásica, a qual correspondeu a 44,7% das cardiopatias de base, quanto às variáveis clínicas e laboratoriais ou à evolução.

Abstract Background In recent years, the incidence of infections related to cardiac implantable electronic devices (CIED) has increased sharply, impacting mortality. Objective To verify the proportion of patients with CIED infection; to analyze their clinical profile and the variables related to the infection and its progression. Methods Retrospective and longitudinal observational study including 123 patients with CIED infection among 6406 procedures. Parametric tests and a level of significance of 5% were used in the statistical analyses Results The mean age of patients was 60.1 years and mean length of stay in hospital was 35.3 days; most (71) patients were male, and the system was completely removed in 105 cases. Infectious endocarditis (IE) and sepsis were observed in 71 and 23 patients, respectively. Intra-hospital mortality was 19.5%. IE was associated with extrusion of the generator (17.0% vs 19.5% with and without IE, respectively, p = 0.04, inverse association) and sepsis (15.4% vs 3.2%, p = 0.01). Intra-hospital death was associated with IE (83.3% vs 52.0% with and without intra-hospital death, respectively, p = 0.005) and sepsis (62.5% vs 8.1%, p < 0.0001). Ninety-nine patients were discharged. During a mean follow-up of 43.8 months, mortality rate was 43%; among patients with sepsis, it was 65.2% (p < 0.0001). By applying a Kaplan-Meier survival curve, we did not indicate significant associations with sex, etiologic agent, ejection fraction, IE, or treatment modality. The death rate was 32.8% for patients subjected to endocardial electrode reimplantation and 52.2% for epicardial reimplantation (p = 0.04). Chagasic etiology (44.7% of the baseline heart diseases) did not influence clinical and laboratory variables or disease progression. Conclusion The infection rate was 1.9%, mostly in men. We observed an association of intra-hospital mortality with IE and sepsis. After discharge, the annual mortality rate was 11.8%, influenced by sepsis during hospitalization and epicardial implantation. (Arq Bras Cardiol. 2021; [online].ahead print, PP.0-0)

Applying the Exploration, Preparation, Implementation, Sustainment (EPIS) Framework to Safe Surgery 2020 Implementation in Tanzania's Lake Zone.

BACKGROUND: Access to safe, high-quality surgical care in sub-Saharan Africa is a critical gap. Interventions to improve surgical quality have been developed, but research on their implementation is still at a nascent stage. We retrospectively applied the Exploration, Preparation, Implementation, Sustainment framework to characterize the implementation of Safe Surgery 2020, a multicomponent intervention to improve surgical quality. METHODS: We used a longitudinal, qualitative research design to examine Safe Surgery 2020 in 10 health facilities in Tanzania's Lake Zone. We used documentation analysis with confirmatory key informant interviews (n = 6) to describe the exploration and preparation phases. We conducted interviews with health facility leaders and surgical team members at 1, 6, and 12 months (n = 101) post initiation to characterize the implementation phase. Data were analyzed using the constant comparison method. RESULTS: In the exploration phase, research, expert consultation, and scoping activities revealed the need for a multicomponent intervention to improve surgical quality. In the preparation phase, onsite visits identified priorities and barriers to implementation to adapt the intervention components and curriculum. In the active implementation phase, 4 themes related to the inner organizational context-vision for safe surgery, existing surgical practices, leadership support, and resilience-and 3 themes related to the intervention-innovation-value fit, holistic approach, and buy-in-facilitated or hindered implementation. Interviewees perceived improvements in teamwork and communication and intra- and inter-facility learning, and their need to deliver safe surgery evolved during the implementation period. CONCLUSIONS: Examining implementation through the exploration, preparation, implementation, and sustainment phases offers insights into the implementation of interventions to improve surgical quality and promote sustainability.

The safety and effectiveness of salvianolate in preventing perioperative venous thromboembolism in China: A PRISMA-compliant meta-analysis based on RCTs.

BACKGROUND: Salvianolate, a common drug for stabilizing heart disease and Angina Pectoris, is considered to be off-label for preventing venous thromboembolism (VTE) or anticoagulation at present. However, many clinical studies have showed that salvianolate can effectively inhibit the deep-vein thrombosis (DVT) incidence, and prevent VTE of perioperative patients in the real world in China. OBJECTIVE: This analysis aimed to evaluate the effectiveness and safety of salvianolate in preventing VTE in perioperative patients. METHODS: Databases of PubMed, Cochrane Library, Embase, CNKI, Wanfang and VIP were searched until July 2019. Literature retrieval, data extraction and quality assessment were independently completed by two researchers and checked with each other. Review Manager 5.2 software was applied for meta-analysis. RESULTS: A total of 429 studies were retrieved, including 11 randomized controlled trials (RCTs) with a total of 1149 subjects. Compared with low molecular weight heparin (LMWH) group alone, salvianolate combined LMWH group had lower DVT incidence in preventing perioperative thrombosis (2.75% and 14.23%, OR: 0.21, 95% CI:[0.08,0.53]; P = .0009). The incidence of adverse reactions of experimental group was similar to that of control group (1.79% and 2.31%, OR: 0.65, 95% CI:[0.18,2.35]. P = .51). Compared with the control group, D-dimer level (D-D), platelet count (PLT), fibrinogen (FIB), whole blood high shear viscosity (WBHSV), and whole blood low shear viscosity (WBLSV) were all significantly decreased (P < .01), and prothrombin time (PT) was significantly increased (P < .05). CONCLUSION: Salvianolate combined LMWH has better effectiveness and the same safety in preventing venous thromboembolism in perioperative patients. However, due to the small number of included literatures, large sample studies are still needed to further verify this conclusion.

Analysis of Pediatric Surgery Using the National Healthcare Insurance Service Database in Korea: How Many Pediatric Surgeons Do We Need in Korea?

BACKGROUND: In the past, general surgeons (GSs) without a pediatric surgical subspecialty often performed surgery on children and, even now, GSs are performing many pediatric surgeries. We aimed to investigate the involvement of pediatric surgeons (PSs) and GSs in pediatric surgery, compare the outcomes of surgery in the neonatal intensive care unit (NICU), and estimate the appropriate PS workforce in Korea. METHODS: We used surgical data from the National Health Insurance Service database that was collected from patients under the age of 19 years in hospitals nationwide from January 2002 to December 2017. In this database, we found 37 hospitals where PSs worked by using the index operation (congenital diaphragmatic hernia, esophageal atresia, hypertrophic pyloric stenosis, Hirschsprung's disease, abdominal wall defect, jejunoileal atresia, malrotation, anorectal malformation, and biliary atresia). It was assumed that the surgery in the 37 hospitals was performed by PS and that the surgery in other hospitals was performed by GS. Mortality was analyzed to compare the outcomes of acute abdominal surgery in the NICU. We estimated the number of PS currently needed in Korea for each situation under the assumption that PS would perform all operations for the index operation, main pediatric diseases (index operation + gastroesophageal reflux disease, choledochal cyst, inguinal hernia, and appendicitis), acute abdominal surgery in the NICU, and all pediatric surgeries. Additionally, we estimated the appropriate number of PS required for more advanced pediatric surgery in the future. RESULTS: The number of pediatric surgeries from 2002 to 2017 increased by 124%. Approximately 10.25% of the total pediatric surgeries were performed by PSs, and the percentage of the surgery performed by PSs increased from 8.32% in 2002 to 15.92% in 2017. The percentage of index operations performed by PSs annually was 62.44% in average. It was only 47.81% in 2002, and increased to 88.79% in 2017. During the last 5 years of the study period, the average annual number of surgeries for main pediatric diseases was approximately 33,228. The ratio of the number of surgeries performed by PS vs. GS steadily increased in main pediatric diseases, however, the ratio of the number of surgery performed by PS for inguinal hernia and appendicitis remained low in the most recent years. The percentage of the number of acute abdominal surgery performed by PS in the NICU was 44% in 2002, but it had recently risen to 89.7%. After 30 days of birth, mortality was significantly lower in all groups that were operated on by PS, rather than GS, during the last 5 years. In 2019, 49 PSs who were under the age of 65 years were actively working in Korea. Assuming that all pediatric surgeries of the patients under the age of 19 years should be performed by PS, the minimum number of PS currently required was about 63 if they perform all of the index operations, the main pediatric surgery was about 209, the NICU operation was about 63, and the all pediatric surgeries was about 366. Additionally, it was determined that approximately 165 to 206 PS will be appropriate for Korea to implement more advanced pediatric surgery in the future. CONCLUSION: The proportion of the pediatric surgery performed by PS rather than GS is increasing in Korea, but it is still widely performed by GS. PSs have better operative outcomes for acute abdominal surgery in the NICU than GSs. We believe that at least the index operation or the NICU operation should be performed by PS for better outcome, and that a minimum of 63 PSs are needed in Korea to do so. In addition, approximately 200 PSs will be required in Korea in order to manage main pediatric diseases and to achieve more advanced pediatric surgery in the future.

A device category economic model of electrosurgery technologies across procedure types: a U.S. hospital budget impact analysis.

AIMS: The electrosurgical technology category is used widely, with a diverse spectrum of devices designed for different surgical needs. Historically, hospitals are supplied with electrosurgical devices from several manufacturers, and those devices are often evaluated separately; it may be more efficient to evaluate the category holistically. This study assessed the health economic impact of adopting an electrosurgical device-category from a single manufacturer. METHODS: A budget impact model was developed from a U.S. hospital perspective. The uptake of electrosurgical devices from EES (Ethicon Electrosurgery), including ultrasonic, advanced bipolar, smoke evacuators, and reusable dispersive electrodes were compared with similar MED (Medical Energy Devices) from multiple manufacturers. It was assumed that an average hospital performed 10,000 annual procedures 80% of which involved electrosurgery. Current utilization assumed 100% MED use, including advanced energy, conventional smoke mitigation options (e.g. ventilation, masks), and single-use disposable dispersive electrode devices. Future utilization assumed 100% EES use, including advanced energy devices, smoke evacuators (i.e. 80% uptake), and reusable dispersive electrodes. Surgical specialties included colorectal, bariatric, gynecology, thoracic and general surgery. Systematic reviews, network meta-analyses, and meta-regressions informed operating room (OR) time, hospital stay, and transfusion model inputs. Costs were assigned to model parameters, and price parity was assumed for advanced energy devices. The costs of disposables for dispersive electrodes and smoke-evacuators were included. RESULTS: The base-case analysis, which assessed the adoption of EES instead of MED for an average U.S. hospital predicted an annual savings of $824,760 ($101 per procedure). Savings were attributable to associated reductions with EES in OR time, days of hospital stay, and volume of disposable electrodes. Sensitivity analyses were consistent with these base-case findings. CONCLUSIONS: Category-wide adoption of electrosurgical devices from a single manufacturer demonstrated economic advantages compared with disaggregated product uptake. Future research should focus on informing comparisons of innovative electrosurgical devices.

Research progress regarding potential effects of traditional Chinese medicine on postoperative intestinal obstruction.

OBJECTIVES: Postoperative intestinal obstruction is a common postoperative complication with typical symptoms of abdominal pain, vomiting, abdominal distension and constipation. The principal aim of this paper is to provide a full-scale review on the categories and characteristics of postoperative intestinal obstruction, pathophysiology, effects and detailed mechanisms of compounds and monomers from traditional Chinese medicine for treating postoperative intestinal obstruction. Moreover, the possible development and perspectives for future research are also analyzed. METHODS: Literature regarding postoperative intestinal obstruction as well as the anti-pio effect of aqueous extracts and monomers from traditional Chinese medicine in the last 20 years was summarized. KEY FINDINGS: To date, approximately 30 compounds and 25 monomers isolated from traditional Chinese medicine including terpenes, alkaloids, polysaccharides, flavonoids, phenylpropanoids and quinones, have exerted significant antipio effect. This paper reviews the effective doses, models, detailed mechanisms, and composition of these traditional Chinese medicine compounds, as well as the structure of these monomers. Moreover, challenges existed in the current investigation and further perspectives were discussed as well, hoping to provide a reference for future clinical treatment of postoperative intestinal obstruction and the development of new drugs. CONCLUSIONS: Above all, the convincing evidence from modern pharmacology studies powerfully supported the great potential of traditional Chinese medicine in the management of postoperative intestinal obstruction. Regrettably, less attention was currently paid on the mechanisms of traditional Chinese medicine compounds and monomers with antipio effect. Consequently, future study should focus on monomer-mechanism and structure-function relationship.

[de la evidencia y algoritmo adaptado Immunonutrition in fast-track surgical patients - Evidence review and adapted algorithm]. / Inmunonutrición del paciente quirúrgico en los procedimientos fast-track: revisión de la evidencia y algoritmo adaptado.

INTRODUCTION: Surgical stress predisposes patients to have immune dysfunction and an increased risk of infection. Malnourished surgical patients have higher postoperative morbidity and mortality rates, higher readmission rates, and higher hospital costs. The use of an immunomodulatory formula is associated in the ESPEN guidelines with a reduction in wound healing problems, suture failure, and infectious and global complications. Several authors have suggested that, since most clinical trials evaluating the efficacy of immunonutrition have been carried out in a traditional perioperative setting, it would be interesting to investigate its efficacy in a more controlled setting, such as in the ERAS (Enhanced Recovery after Surgery) protocol. The objective of this work was: a) to define the role that immunonutrition should play in ERAS protocols based on the best scientific evidence available; b) to analyze the difficulties that continue to exist in real-life clinical practice to screen the nutritional risk of patients; c) to make a proposal of algorithms adapted to the characteristics of our environment regarding the screening, assessment, and nutritional treatment of surgical patients in fast-track surgery.

INTRODUCCIÓN: El estrés quirúrgico predispone a los pacientes a la disfunción inmune y a un mayor riesgo de infección. Los pacientes quirúrgicos desnutridos presentan una mayor morbimortalidad posoperatoria, mayores tasas de reingreso y costes hospitalarios más elevados. En las guías de la ESPEN se asocia el uso de una fórmula inmunomoduladora a una reducción significativa de los problemas de la cicatrización de heridas, de los fallos de la sutura y de las complicaciones infecciosas y globales. Varios autores han sugerido que, dado que la mayoría de los ensayos clínicos que evalúan la eficacia de la inmunonutrición se han realizado en un entorno perioperatorio tradicional, sería interesante investigar su eficacia en un entorno más controlado, como en el protocolo ERAS (Enhanced Recovery after Surgery). El objetivo de este trabajo es: a) definir el papel que debe jugar la inmunonutrición en los protocolos ERAS sobre la base de la mejor evidencia científica; b) analizar las dificultades que siguen existiendo en la práctica clínica real para realizar el cribado del riesgo nutricional del paciente; c) proponer unos algoritmos adaptados a las características de nuestro entorno sobre el cribado, la valoración y el tratamiento nutricional del paciente quirúrgico en modalidad fast-track.

Especificidades clínico-epidemiológicas y diagnósticas del cáncer de colon con metástasis hepáticas sincrónicas / Clinical-Epidemiological Specificities of Colon Cancer Diagnosed with Synchronic Metastasis

Introducción: El cáncer de colon se erige como la neoplasia del tubo digestivo más frecuente en la presente centuria. Objetivo: Identificar algunos factores clínicos, epidemiológicos y diagnósticos en pacientes operados de cáncer de colon con metástasis hepática sincrónica. Métodos: Se realizó un estudio observacional, descriptivo y transversal de una muestra de 31 pacientes operados con diagnóstico definitivo de cáncer de colon con metástasis hepática sincrónica, en el servicio de Cirugía General del Hospital Provincial Docente "Saturnino Lora" de Santiago de Cuba durante el periodo comprendido entre 2010 y 2019. Resultados: La edad promedio fue de 63,2 años. Existió predominio de la enfermedad inflamatoria intestinal como antecedente patológico personal, y del alcoholismo como factor de riesgo. La sintomatología predominante fue dolor abdominal y cambios del hábito intestinal, así como el tumor palpable al examen físico del abdomen. La ecografía abdominal y el colon por enema fueron los procederes de diagnóstico más utilizados. Prevalecieron los tumores en el colon izquierdo a nivel del descendente. Todos los tumores malignos fueron adenocarcinomas a predominio de los moderadamente diferenciados. Conclusiones: Las edades avanzadas de la vida, así como la presencia de tabaquismo y alcoholismo son factores epidemiológicos característicos de la población de enfermos aquejados de cáncer de colon con metástasis hepática. Los elementos clínicos identificados constituyeron los habitualmente descritos en la literatura médica, aunque los estudios imaginológicos utilizados preoperatoriamente resultaron limitados para el diagnóstico del cáncer de colon con metástasis hepática sincrónica, precisándose el hallazgo de las lesiones metastásicas durante la intervención quirúrgica(AU)

Introduction: Colon cancer is the most frequent digestive-tract neoplasm in the present century. Objective: To identify some clinical, epidemiological and diagnostic factors in patients operated on for colon cancer and synchronic hepatic metastasis. Methods: An observational, descriptive and cross-sectional study was carried out in a sample of 31 patients operated on with a definitive diagnosis of colon cancer and synchronic hepatic metastasis, in the general surgery service of Saturnino Provincial Teaching Hospital in Santiago de Cuba, during the period between 2010 and 2019. Results: The average age was 63.2 years. There was a predominance of inflammatory intestinal disease as a personal pathological antecedent, as well as alcoholism as a risk factor. The predominant symptoms were abdominal pain and changes in intestinal habits, as well as a tumor palpable on physical abdominal examination. Abdominal ultrasound and lower barium enema were the most used diagnostic procedures. Tumors prevailed at the level of the left descending colon. All malignant tumors were adenocarcinomas, predominantly moderately differentiated ones. Conclusions: Advanced ages of life, as well as smoking and alcoholism are characteristic epidemiological factors among the population of patients suffering from colon cancer with hepatic metastases. The clinical elements identified were those usually described in the medical literature, although the imaging studies used preoperatively were limited for the diagnosis of colon cancer with synchronic hepatic metastasis, a fact that required finding metastatic lesions during surgery(AU)

Effect of a behavioral intervention on anxiety and perceived performance of non-technical skills during surgical simulations.

BACKGROUND: Surgical trainees experience intrinsic stress and anxiety during high-acuity clinical situations which can negatively impact performance. Emerging data suggests that education in mindfulness-based coping techniques may improve performance. We evaluated the effects of a stress recovery intervention on novice trainees' perceived level of anxiety during an intentionally stressful simulation. METHODS: Participants were recruited from surgical intern classes over three consecutive years. All participants completed a simulation intentionally designed to evoke a stress response. Participants then completed a stress recovery intervention or received no additional training. All participants then completed a second novel simulation. RESULTS: Intervention participants had significantly higher self-reported ability to manage stress (intervention 2.4 to 3.6, p < 0.01; control 2.8 to 3.3, p = 0.06), and stop, think, and observe (intervention 2.5 to 3.7, p < 0.01; control 2.6 to 3.3, p = 0.08) during the second simulation. Both groups also had significantly lower levels of state anxiety during the second simulation as compared to the first (intervention 45.1 vs 59.3, p < 0.01; control 49.3 vs 57.4, p < 0.05). During the second simulation, trainees in both groups reported improvements in perceived abilities to: recognize stress (intervention 2.7 to 4.1, p < 0.01; control 2.9 to 3.6, p < 0.05), communicate with and lead their team (intervention 2.4 to 3.3, p < 0.05; control 2.3 to 3.3, p < 0.01), and to prioritize, plan, and prepare (intervention 2.1 to 3.1, p < 0.05; control 2.1 to 3.0, p < 0.01). CONCLUSION: Our research shows that a brief intervention was associated with a significant increase in trainee ability to both recognize internal stress and engage in proactive coping mechanisms. This research also shows that while repeated stress-inducing simulations may themselves decrease perceived anxiety levels in novice surgical trainees, training in coping strategies may potentiate this effect.
