Role of surgical simulation on self-reported confidence level on cardiothoracic surgical trainees.

BACKGROUND: Simulated self-practice using simulation models could improve fine motor skills and self confidence in surgical trainees. AIMS: The purpose of this study is to evaluate on self-reported confidence level in cardiothoracic surgical trainees by using surgical simulation models. METHODS: We conducted a cross-sectional study on all surgeons (n=10) involved in MIS simulation training. All surgeons are required to perform on three minimally invasive surgery (MIS) procedures (Mitral Valve Repair, Mitral Valve Replacement and Aortic Valve Replacement). A questionnaire was designed based on two existing scales related to self-confidence, the surgical self-efficacy scale [SSES] and the perceived competency scale [PCS]. We assessed their self-confidence (before and after training) in the use of simulation in MIS procedures using rating scales 1-5. The mean score was calculated for each domain and used as the predictor variable. We also developed six questions (PCS) using Objective Structured Assessment of Technical Skills (OSAT) related to each domain and asked participants how confident they were after performing each MICS procedure. RESULTS: The mean score was 4.7 for all assessed domains, except "knowledge" (3.8). Surgeons who had performed one or more MIS procedures had higher scores (P<0.05). There was no correlation between the number of MIS procedures performed and self-confidence scores. CONCLUSIONS: The results indicate that the cardiac surgery training based on MIS simulation improves trainees and consultants in terms of the level of self-confidence. Although surgeons generally have high levels of self-confidence after simulation training in MIS cardiac procedures, there is still room for improvement with respect to technical skills related to the procedure itself and its results.

ObjectiveTo describe and characterize a cohort of octogenarian patients admitted to the ICU of the University Central Hospital of Asturias (HUCA). Design Retrospective, observational and descriptive study of 14 months’ duration. Setting Cardiac and Medical Intensive Care Units (ICU) of the HUCA (Oviedo). Participants Patients over 80 years old who were admitted to the ICU for more than 24hours. Interventions None. Main variables of interest Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality. Results The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p=0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p=<0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR=0,18; 95% CI (0,062-0,527; p=0,002). Conclusions The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty. (AU)

Early comparison robotic bronchoscopy versus electromagnetic navigational bronchoscopy for biopsy of pulmonary nodules in a thoracic surgery practice.

Pulmonary nodules are frequently encountered in high-risk patients. Often these require biopsy which can be challenging. We relate our experience comparing use of electromagnetic navigational bronchoscopy (ENB) to a robotic bronchoscopy system (RB). A retrospective review of patients undergoing bronchoscopic biopsy from 2015 to 2021. The timeframe overlapped with transition from ENB using Veran SPiN system to RB using Ion system by Intuitive. Patient and nodule characteristics were collected. Primary end point was overall diagnostic yield which was defined by pathologic confirmation of malignancy or benign finding. Secondary outcomes included diagnostic yield based on overall size of nodules and need for further work up and testing. 116 patients underwent ENB or RB of 134 nodules. No perioperative complications occurred. Diagnostic yield of ENB was 49.5% (41/91 nodules) versus 86.1% (37/43 nodules) for RB. Average nodule size for ENB was 2.55 cm versus 1.96 cm for RB. When divided based on size, ENB had a 30% diagnostic yield for nodules 1-2 cm (11/37 nodules, mean size 1.46 cm) and 64% yield for nodules 2-3 cm (14/22 nodules, mean size 2.38 cm). RB had an 81% yield for nodules 1-2 cm (mean size 1.41 cm) and 100% yield for nodules 2-3 cm (mean 2.3 cm). RB showed superiority over ENB in early implementation trials for biopsy of suspicious pulmonary nodules. It is a safe technology allowing for increased access to all lung fields and utilization in the thoracic surgical practice will be paramount to advancing the field.

Perioperative considerations for robotic-assisted thoracic surgery.

Robotic-assisted thoracic surgery is being offered to more patients because it has a number of potential benefits. Awareness of the challenges that this type of surgery brings will allow teams to manage these patients safely in the perioperative period.

Biochemical markers in emergency thoracic surgery in penetrating trauma.

BACKGROUND: Violent interpersonal acts account for a large proportion of unnatural deaths in South Africa. A significant proportion of unnatural deaths are due to penetrating thoracic trauma and preventable haemorrhage. Current indications for emergent thoracotomy are unreliable. We propose the use of lactate, shock index (SI) and base deficit (BD) as a triage tool in patients with penetrating thoracic injuries to identify those requiring surgical intervention. METHODS: A review of the trauma registry of the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) was carried out between March 2011 and March 2016. Four hundred and ninety (490) patients were collected consisting of a non-operative group of 246 patients and an operative group of 244 patients. We compared lactate, SI and BD independently and within panels to ascertain which would best predict the need for operative intervention in these patients. Abnormal was defined as lactate ≥ 4 mmol/l, SI ≥ 0.8 and BD ≤ -4 mmol/l. RESULTS: Of the 490 patients, lactate (p < 0.001), SI (p < 0.001) and BD (p < 0.001) differed significantly between operative and non-operative groups. Statistical significance was lost (p = 0.34) once BD was analysed in combination with lactate and SI. Lactate alone was a strong predictor of the need for intervention (area under the curve (AUC) = 0.814). The strongest predictor was a combined panel of lactate and SI (AUC = 0.8308, p < 0.001). CONCLUSION: Lactate and SI in combination are useful as triage tools, and could assist in decision making, by predicting which patients are more likely to require surgical intervention.

[Pre-rehabilitation of oncological patients before extensive abdominal and thoracic surgery: a literature review]. / Prereabilitatsiya onkologicheskikh patsientov pered obshirnym khirurgicheskim vmeshatel'stvom v bryushnoi i grudnoi polostyakh: obzor literatury.

Surgery is one of the leading treatment methods of patients with primary or recurrent malignant neoplasms in the thoracic or abdominal cavity. Extensive abdominal interventions are accompanied by such adverse outcomes as blood loss, hypoxia, inflammation, blood clotting abnormality, emotional and cognitive disorders, that increases the incidence of serious complications and worsens the treatment outcome and life quality in weakened oncological patients. Multimodal pre-rehabilitation before surgery can significantly decrease the incidence and severity of postoperative complications. The rehabilitation complex includes exercise therapy, nutritional and psychological support, smoking cessation and pharmacotherapy. Currently, there are a number of questions facing rehabilitation specialists and oncologists, that are related to the determination of pre-rehabilitation optimal timing and process duration, the choice of specific physical exercises, determining the load intensity. This review presents a current view on understanding of surgical stress in extensive abdominal interventions, its effect on the oncological process course, summarizes the experience of last years in choosing pre-rehabilitation program taking into account pathogenetic mechanisms of surgical stress and individual patient's characteristics. Special attention is paid to the comparison of physical exercises' various types, their action mechanisms at different stages of pathological process, the issues of load dosing during pre-rehabilitation activities.

Efficacy and safety of tranexamic acid in patients undergoing thoracic surgery: a systematic review and PRISMA-compliant meta-analysis

OBJECTIVES: Perioperative bleeding poses a significant issue during thoracic surgery. Tranexamic acid (TXA) is one of the most commonly used antifibrinolytic agents for surgical patients. The purpose of the current study was designed to investigate the efficacy and safety of TXA in patients undergoing thoracic surgery. METHODS: An extensive search of PubMed, Web of Science (WOS), Cochrane Library (trials), Embase, OVID, China National Knowledge Infrastructure (CNKI), Wanfang, and VIP electronic databases was performed to identify studies published between the inception of these databases and March 2023. The primary outcomes included perioperative blood loss and blood transfusions. Secondary outcomes of interest included the length of stay (LOS) in hospital and the incidence of thromboembolic events. Weighted mean differences (WMDs) or odds ratios (OR) with 95% confidence intervals (CI) were used to determine treatment effects for continuous and dichotomous variables, respectively. RESULTS: Five qualified studies including 307 thoracic surgical patients were included in the current study. Among them, 65 patients were randomly allocated to the group receiving TXA administration (the TXA group); the other 142 patients were assigned to the group not receiving TXA administration (the control group). TXA significantly reduced the quantity of hemorrhage in the postoperative period (postoperative 12h: WMD = -81.90 ml; 95% CI: -139.55 to -24.26; P = 0.005; postoperative 24h: WMD = -97.44 ml; 95% CI: -121.44 to -73.44; P< 0.00001); The intraoperative blood transfusion volume (WMD = -0.54 units; 95% CI: -1.06 to -0.03; P = 0.04); LOS in hospital (WMD = -0.6 days; 95% CI: -1.04 to -0.16; P = 0.008); And there was no postoperative thromboembolic event reported in the included studies. CONCLUSIONS: The present study demonstrated that TXA significantly decreased blood loss within 12 and 24 hours postoperatively. A qualitative review did not identify elevated risks of safety outcomes such as thromboembolic events. It also suggested that TXA administration was associated with shorter LOS in hospital as compared to control. To validate this further, additional well-planned and adequately powered randomized studies are necessary.

Lung cancer screening in Brazil: recommendations from the Brazilian Society of Thoracic Surgery, Brazilian Thoracic Association, and Brazilian College of Radiology and Diagnostic Imaging.

Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary. With the aim of increasing knowledge and stimulating debate on LCS, the Brazilian Society of Thoracic Surgery, the Brazilian Thoracic Association, and the Brazilian College of Radiology and Diagnostic Imaging convened a panel of experts to prepare recommendations for LCS in Brazil. The recommendations presented here were based on a narrative review of the literature, with an emphasis on large population-based studies, systematic reviews, and the recommendations of international guidelines, and were developed after extensive discussion by the panel of experts. The following topics were reviewed: reasons for screening; general considerations about smoking; epidemiology of LC; eligibility criteria; incidental findings; granulomatous lesions; probabilistic models; minimum requirements for LDCT; volumetric acquisition; risks of screening; minimum structure and role of the multidisciplinary team; practice according to the Lung CT Screening Reporting and Data System; costs versus benefits of screening; and future perspectives for LCS.

Perfil clínico, abordaje y pronóstico del paciente con shock cardiogénico sometido a traslado interhospitalario en España / Clinical profile, management and outcomes of patients with cardiogenic shock undergoing transfer between centers in Spain

Introducción y objetivos El objetivo es analizar el perfil clínico, el abordaje y el pronóstico del shock cardiogénico (SC) por infarto agudo de miocardio con elevación del segmento ST (IAMCEST) que requiere traslado interhospitalario, así como el impacto pronóstico de las variables estructurales de los centros en este contexto. Métodos Se incluyó a los pacientes con SC-IAMCEST atendidos en centros con capacidad de revascularización (2016-2020). Se consideró a: a) pacientes atendidos durante todo el ingreso en hospitales con cardiología intervencionista sin cirugía cardiaca; b) pacientes atendidos en hospitales con cardiología intervencionista y cirugía cardiaca, y c) pacientes trasladados a centros con cardiología intervencionista y cirugía cardiaca. Se analizó la asociación del volumen de SC-IAMCEST atendidos y la disponibilidad de cuidados intensivos cardiológicos (UCIC) y trasplante cardiaco con la mortalidad hospitalaria. Resultados Se incluyeron 4.189 episodios, 1.389 (33,2%) del grupo A, 2.627 del grupo B (62,7%) y 173 del grupo C (4,1%). Los pacientes trasladados eran más jóvenes, tenían más riesgo cardiovascular y recibieron más frecuentemente revascularización, asistencia circulatoria y trasplante cardiaco durante el ingreso (p<0,001). Los pacientes trasladados presentaron menor tasa bruta de mortalidad (el 46,2 frente al 60,3% del grupo A y el 54,4% del grupo B; p<0,001). Mayor volumen asistencial (OR=0,75; p =0,009) y disponibilidad de UCIC (OR=0,80; p =0,047) se asociaron con menor mortalidad. Conclusiones El porcentaje de SC-IAMCEST trasladados en nuestro medio es bajo. Los pacientes trasladados son más jóvenes y reciben más procedimientos invasivos. Los traslados a centros con mayor volumen y UCIC presentan menor mortalidad. (AU)

Introduction and objectives The aim of this study was to analyze the clinical profile, management, and prognosis of ST segment elevation myocardial infarction-related cardiogenic shock (STEMI-CS) requiring interhospital transfer, as well as the prognostic impact of structural variables of the treating centers in this setting. Methods This study included patients with STEMI-CS treated at revascularization-capable centers from 2016 to 2020. The patients were divided into the following groups: group A: patients attended throughout their admission at hospitals with interventional cardiology without cardiac surgery; group B: patients treated at hospitals with interventional cardiology and cardiac surgery; and group C: patients transferred to centers with interventional cardiology and cardiac surgery. We analyzed the association between the volume of STEMI-CS cases treated, the availability of cardiac intensive care units (CICU), and heart transplant with hospital mortality. Results A total of 4189 episodes were included: 1389 (33.2%) from group A, 2627 from group B (62.7%), and 173 from group C (4.1%). Transferred patients were younger, had a higher cardiovascular risk, and more commonly underwent revascularization, mechanical circulatory support, and heart transplant during hospitalization (P<.001). The crude mortality rate was lower in transferred patients (46.2% vs 60.3% in group A and 54.4% in group B, (P<.001)). Lower mortality was associated with a higher volume of care and CICU availability (OR, 0.75, P=.009; and 0.80, P=.047). Conclusions The proportion of transfers in patients with STEMI-CS in our setting is low. Transferred patients were younger and underwent more invasive procedures. Mortality was lower among patients transferred to centers with a higher volume of STEMI-CS cases and CICU. (AU)

Impact of Pleural Lavage Cytology Positivity on Early Recurrence After Surgery for Non-Small Cell Lung Cancer / Impacto de la positividad de la citología del lavado pleural en la recurrencia temprana después de la cirugía por cáncer de pulmón de células no pequeñas

Objective: The aim of this study was to elucidate the impact of pleural lavage cytology positivity on early recurrence in patients operated on non-small cell lung cancer (NSCLC). Methods: This is a multicentre prospective cohort study of 684 patients undergoing an anatomical lung resection for NSCLC between October 2015 and October 2017 at 12 national centres. A pleural lavage was performed before and after lung resection. The association between the different predictors of early recurrence and PLC positivity was performed using univariate and multivariate logistic regression models. A propensity score analysis was performed by inverse probability weighting (IPSW) using average treatment effect (ATE) estimation to analyse the impact of PLC positivity on early recurrence. Results: Overall PLC positivity was observed in 15 patients (2.2%). After two years, 193 patients (28.2%) relapsed, 182 (27.2%) with a negative PLC and 11 (73.3%) with a positive PLC (p<0.001). Factors associated to early recurrence were adenocarcinoma histology (OR=1.59, 95%CI 1.06–2.38, p=0.025), visceral pleural invasion (OR=1.59, 95%CI 1.04–2.4, p=0.03), lymph node involvement (OR=1.84, 95%CI 1.14–2.96, p=0.013), advanced pathological stage (OR=2.12, 95%CI 1.27–3.54, p=0.004) and PLC positivity (OR=4.14, 95%CI 1.25–16.36, p=0.028). After IPSW, PLC positivity was associated with an increased risk of early recurrence (OR=3.46, 95%CI 2.25–5.36, p<0.001). Conclusions: Positive pleural lavage cytology was found to be the strongest predictor of early recurrence.(AU)

The ESTS-AIR database-initial results of a multi-institutional database on airway surgery.

OBJECTIVES: Compared to lung resections, airway procedures are relatively rare in thoracic surgery. Despite this, a growing number of dedicated airway centres have formed throughout Europe. These centres are characterized by a close interdisciplinary collaboration and they often act as supra-regional referring centres. To date, most evidence of airway surgery comes from retrospective, single-centre analysis as there is a lack of large-scale, multi-institutional databases. METHODS: In 2018, an initiative was formed, which aimed to create an airway database within the framework of the ESTS database (ESTS-AIR). Five dedicated airway centres were asked to test the database in a pilot phase. A 1st descriptive analysis of ESTS-AIR was performed. RESULTS: A total of 415 cases were included in the analysis. For adults, the most common indication for airway surgery was post-tracheostomy stenosis and idiopathic subglottic stenosis; in children, most resections/reconstructions had to be performed for post-intubation stenosis. Malignant indications required significantly longer resections [36.0 (21.4-50.6) mm] when compared to benign indications [26.6 (9.4-43.8) mm]. Length of hospital stay was 11.0 (4.1-17.3) days (adults) and 13.4 (7.6-19.6) days (children). Overall, the rates of complications were low with wound infections being reported as the most common morbidity. CONCLUSIONS: This evaluation of the 1st cases in the ESTS-AIR database allowed a large-scale analysis of the practice of airway surgery in dedicated European airway centres. It provides proof for the functionality of ESTS-AIR and sets the basis for rolling out the AIR subsection to all centres participating in the ESTS database.

The Society of Thoracic Surgeons Congenital Heart Surgery Database: 2023 Update on Outcomes and Research.

The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (CHSD) continues to be the most comprehensive database of congenital and pediatric cardiothoracic surgical procedures in the world and contains information on 664,210 operations as of June 30, 2023. The 35th harvest of the STS CHSD data was undertaken in Spring 2023, spanning the 4-year period January 1, 2019, through December 31, 2022, and included 144,919 operations performed at 114 participating sites in North America. The harvest analysis was successfully executed by the STS Research and Analytic Center. The overall unadjusted mortality rate was 2.68% and has remained stable over the 4 years included in the current harvest window. Mortality is highest in neonates (7.4%) and lowest in children (1.1%). As in prior analyses, observed mortality and postoperative length of stay in the database increase with an increase in STS-European Association for Cardio-Thoracic Surgery (STAT) Congenital Heart Surgery Mortality Categories. This quality report summarizes contemporary outcomes, provides the odds ratios for the CHSD risk model variables based on this analysis, and describes on-going efforts to improve data collection and augment analytical approaches. Lastly, 5 research publications completed in the last year using data from the CHSD are also summarized.

Comparison of ultrasound-guided subtransverse process interligamentary plane block with paravertebral block for postoperative analgesia in thoracic surgery: protocol for a randomised non-inferiority trial.

INTRODUCTION: The subtransverse process interligamentary (STIL) plane block is an emerging interfascial plane block that has garnered attention for its potential to provide effective postoperative analgesia for breast and thoracic surgeries. However, a direct comparative assessment between the STIL plane block and the paravertebral block is currently lacking. Consequently, our study aims to assess the analgesic efficacy of the STIL block in comparison to paravertebral block for patients undergoing video-assisted thoracoscopic surgery (VATS). METHODS AND ANALYSIS: This study is a randomised, parallel-controlled, double-blind, non-inferiority trial, with the goal of enrolling 114 participants scheduled for uniportal VATS at Shanghai Pulmonary Hospital. Participants will be randomly assigned in a 1:1 ratio through block randomisation to receive either the STIL plane block (n=57) or the paravertebral block (n=57). The primary outcome of the study is the area under the curve of Numerical Rating Scale(NRS) scores recorded over a 48-hour period following the surgical procedure. Secondary outcomes encompass the evaluation of Quality of Recovery-40, cumulative sufentanil consumption, serum inflammatory factors, rescue medication usage, the incidence of adverse events and the patient satisfaction scores. ETHICS AND DISSEMINATION: This study has received approval from the Medical Ethics Committee of Shanghai Pulmonary Hospital (approval no. L22-329). Written informed consent will be obtained from all participants. The findings will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ChiCTR2200066909.

Cardiac Tamponade Caused By Carbon Dioxide Insufflation During Robot-Assisted Thoracic Surgery: A Case Report.

Various complications can occur during robot-assisted thoracic surgery for mediastinal tumors owing to carbon dioxide (CO2) insufflation. This study reports the case of a 43-year-old woman who underwent robot-assisted surgery for an anterior mediastinal tumor with the subxiphoid approach. Shortly after starting CO2 insufflation, the blood pressure decreased significantly. Subsequent examination of the mediastinum revealed a left-sided pericardial injury. Cardiac tamponade due to entry of CO2 gas into the pericardial cavity was suspected. A deliberate incision was made in the right pericardium, ultimately resolving the cardiac tamponade and substantially improving the patient's blood pressure.
