ABSTRACT

Introducción: La infección por SARS-CoV-2 puede presentar síndrome de distrés res-piratorio agudo con requerimiento de ventilación mecánica prolongada y retraso en la realización de traqueostomía. Esto trae como consecuencia un incremento en casos de estenosis traqueal y la necesidad de métodos menos invasivos para su abordaje. Métodos: Estudio descriptivo de corte transversal, desde marzo 2020 hasta diciem-bre 2021 en el Hospital Universitario Nacional de Colombia, en adultos con estenosis traqueal postintubación asociado SARS-CoV-2. Se realizó análisis univariado entre los grupos con infección o no por SARS-CoV-2 como control, y reintervención, grado de estenosis, uso de inyección intramucosa con dexametasona intratraqueal o múltiples estenosis como desenlaces de importancia. Se usó test exacto de Fisher, t Student y Man-Whitney según la naturaleza de variables. Se consideró p estadísticamente significativo menor a 0.05.Resultados: Se identificaron 26 pacientes, 20 tenían COVID-19 y 6 no. Se encontraron diferencias en edad (p=0,002), epilepsia (p=0,007) y estenosis múltiple (p= 0,04). En 85% de los casos se utilizó láser blue más dilatación con balón pulmonar, en 35% inyección intramucosa con dexametasona intratraqueal y reintervención en 35%, sin diferencias significativas entre grupos. Conclusiones: Se observó un incremento tres veces mayor de pacientes con estenosis múltiple en el grupo de infección por COVID-19, así mismo se encontró que el método más utilizado en este grupo para la recanalización fue el uso de láser blue más dilatación con balón pulmonar y la innovación en el uso de inyección intramucosa.


Introduction: SARS-CoV-2 infection can lead to acute respiratory distress syndrome with a prolonged need for mechanical ventilation and delayed tracheostomy, resulting in an increase in cases of tracheal stenosis and the necessity for less invasive approaches.Methods: A descriptive cross-sectional study was conducted from March 2020 to December 2021 at the Hospital Universitario Nacional de Colombia, focusing on adults with post-intubation tracheal stenosis associated with SARS-CoV-2. Univariate analysis was performed between groups with or without SARS-CoV-2 infection as a control, considering reintervention, degree of stenosis, use of intratracheal steroids, or multiple stenoses as important outcomes. Fisher's exact test, Student's t-test, and Mann-Whit-ney test were employed based on the nature of variables. A p-value less than 0.05 was considered statistically significant.Results: A total of 26 patients were included, with 20 having COVID-19 and 6 without. Significant differences were found in age (p=0.002), epilepsy (p=0.007), and multiple stenosis (p=0.04). In 85% of cases, laser blue plus balloon pulmonary dilation was used, intratracheal dexamethasone in 35%, and reintervention in 35%, with no significant differences between groups.Conclusions: A threefold increase in subglottic stenosis was observed during the SARS-CoV-2 pandemic, with more instances of multiple stenosis and predominantly the use of laser blue plus balloon pulmonary dilation as a successful recanalization technique. There was a higher use of intratracheal dexamethasone in this group compared to oth-er pathologies causing tracheal stenosis.

ABSTRACT

OBJECTIVES@#To optimize the oxygen therapy regimens for infants with pulmonary diseases during bronchoscopy.@*METHODS@#A prospective randomized, controlled, and single-center clinical trial was conducted on 42 infants who underwent electronic bronchoscopy from July 2019 to July 2021. These infants were divided into a nasal cannula (NC) group and a modified T-piece resuscitator (TPR) group using a random number table. The lowest intraoperative blood oxygen saturation was recorded as the primary outcome, and intraoperative heart rate and respiratory results were recorded as the secondary outcomes.@*RESULTS@#Compared with the NC group, the modified TPR group had a significantly higher level of minimum oxygen saturation during surgery and a significantly lower incidence rate of hypoxemia (P<0.05). In the modified TPR group, there were 6 infants with mild hypoxemia, 2 with moderate hypoxemia, and 1 with severe hypoxemia, while in the NC group, there were 3 infants with mild hypoxemia, 5 with moderate hypoxemia, and 9 with severe hypoxemia (P<0.05). The modified TPR group had a significantly lower incidence rate of intraoperative respiratory rhythm abnormalities than the NC group (P<0.05), but there was no significant difference in the incidence rate of arrhythmias between the two groups (P>0.05).@*CONCLUSIONS@#Modified TPR can significantly reduce the risk of hypoxemia in infants with pulmonary diseases during electronic bronchoscopy, and TPR significantly decreases the severity of hypoxemia and the incidence of respiratory rhythm abnormalities compared with traditional NC.

ABSTRACT

Presentamos el caso de un niño de 12 años que consultó por hemoptisis, sin otros sín- tomas asociados. Se realizó radiografía de tórax (patológica), laboratorio con aumen- to moderado de reactantes de fase aguda, PPD (negativa), esputos x 3 con bacilosco- pias negativas y tomografía de tórax con contraste i.v. que mostró imágenes de árbol en brote en todos los lóbulos y una imagen de dilatación vascular de una rama de la ar- teria pulmonar en lóbulo superior izquierdo. Se plantearon diagnósticos diferenciales: malformación vascular primaria o lesión secundaria a infección. La angiografía digital permitió confirmar el pseudoaneurisma y embolizarlo. Luego de 17 días, 2/3 cultivos de esputo fueron positivos para Mycobacterium tuberculosis. El niño realizó tratamiento antituberculoso con drogas de primera línea con evolución clínica favorable. Este caso resalta la importancia de considerar el pseudoaneurisma de Rasmussen en- tre las posibles complicaciones de un paciente con tuberculosis y hemoptisis recurren- te o masiva.


We present the case of a 12-year-old boy admitted to the hospital due to hemoptysis without other symptoms. We performed a Thorax X-Ray (pathological), laboratory with elevated acute phase reactants, TST (negative), sputum x 3 with negative smear and computed tomography angiography showing a tree-in-bud pattern in all lobes, and di-latation of a brunch of the pulmonary artery in the upper left lobe. We considered pri-mary vascular anomaly or lesion due to infection as a differential diagnosis. The patient underwent digital angiography and therapeutic embolization of this pseudoaneurysm. After seventeen days, 2/3 of the sputum cultures were positive for Mycobacterium tu-berculosis. The patient received standard anti-TB therapy with favorable evolution. This case highlights the importance of considering complications such as Rasmussen's pseudoaneurysm in patients with pulmonary tuberculosis and recurrent or massive hemoptysis.

ABSTRACT

Introducción: la neumonía lipoidea exógena es una enfermedad pulmonar inflamatoria poco común, desencadenada por la inhalación o aspiración de material graso de origen animal, vegetal o mineral. El diagnóstico se establece a través de confirmación histo-patológica, por la presencia de macrófagos cargados de lípidos en muestras respirato-rias, asociado a las características clínicas específicas al momento de su presentación.Requiere de un alto nivel de sospecha y una adecuada anamnesis de los antecedentes exposicionales del paciente debido a que muchos casos son subdiagnosticados y trat-ados como neumonía adquirida en la comunidad, lo que retrasa su diagnóstico y mane-jo, sumado a la ausencia de guías disponibles para su tratamiento.Se han reportado pocos casos de sobreinfección por tuberculosis en pacientes con neu-monía lipoidea exógena crónica. Caso clínico: femenino 33 años, con antecedentes de exposición crónica a sustancias desinfectantes de características aceitosas sin protección de vía aérea, con cuadro de tos y dolor torácico. Conclusión: el diagnóstico temprano, asociado a tratamiento de soporte, general-mente conservador, favorece la mejoría clínica y radiológica, y de esta manera dis-minuye la morbimortalidad. (AU)


Introduction: exogenous lipoid pneumonia is a rare inflammatory lung disease, trigge-red by inhalation or aspiration of fatty material of animal, vegetable or mineral origin. The diagnosis is established through histological confirmation by the presence of lipid-laden macrophages in respiratory samples, associated with the specific clinical charac-teristics at the time of presentation. It requires a high level of suspicion and an adequate anamnesis of the patient's expo-sure history, since many cases are underdiagnosed and treated as community-acquired pneumonia, what delays its diagnosis and management, added to the absence of avai-lable guidelines for its treatment. Few cases of tuberculosis superinfection have been reported in patients with exoge-nous lipoid pneumonia.Clinical case: 33-year-old female, with a history of chronic exposure to oily disinfectant substances without airway protection, with symptoms of cough and chest pain.Conclusion: early diagnosis, associated with supportive treatment, generally conser-vative, favors clinical and radiological improvement, thus reducing morbidity and mor-tality.

ABSTRACT

Objective@#This single-subject case study was done to evaluate the presence and evaluate the risk factors for the development of Work-Related Musculoskeletal Disorders (WMSDs) among the staff performing bronchoscopy in the bronchoscopy suite.@*Methods@#A single-subject case study to describe the ergonomic issues in bronchoscopy including identifying multiple factors that can potentially, either singly or in combination, affect physical work capacity. The study focused on the evaluation and control of occupational factors during bronchoscopy to improve awareness of ergonomic issues in bronchoscopy using the following data collection tools: 1) hierarchical task analysis, 2) activity sampling, 3) direct observation of the procedure (walk-around), 5) structured interview of the subject, and 5) utilization of checklists.@*Results@#During the process of bronchoscopy, identified factors that can cause pain in the wrists, fingers, and shoulders include repetitive movement and awkward positions of the hands and wrists coming from the need to move the directional controls and position the bronchoscope. For the back, prolonged standing with awkward postures is a concern. For the neck, the need to look at the monitor which is situated at the side of the patient and frequent shifting of the eyes and head from the monitor to the patient can cause neck pain and stiffness. Aside from the above, other factors would include job stress from the workload, inadequate time for rest and recovery, and the possibility of an uncomfortable environment due to poor air quality. Chronic exposure and repeated injury followed by inflammation and repair lead to structural and biochemical changes in the tissues affected by Cumulative Trauma Disorders (CTDs) leading to the development of WMSDs.@*Conclusion@#Although CTDs do not account for work-related deaths, they do account for a significant amount of human suffering, loss of productivity, and economic burden on the compensation system. Thus, ergonomic concerns must be addressed early to prevent WMSDs/CTDs.

ABSTRACT

OBJECTIVES@#To investigate the clinical application of metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid (BALF) in the etiological diagnosis and treatment of refractory pneumonia (RTP) in children.@*METHODS@#A retrospective analysis was performed on 160 children with RTP who were admitted to the Department of Pediatric Internal Medicine, Maternal and Child Health Hospital of Inner Mongolia Autonomous Region, from January 2020 to March 2023. According to whether mNGS was performed, they were divided into two groups: mNGS (n=80) and traditional testing (n=80). All children received the tests of inflammatory markers and pathogen tests after admission. Traditional pathogenicity tests included microbial culture (sputum specimen collected by suction tube), nucleic acid detection of respiratory pathogens, and serological test (mycoplasma, tuberculosis, and fungi). For the mNGS group, BALF specimens were collected after bronchoscopy and were sent to the laboratory for mNGS and microbial culture. The two groups were analyzed and compared in terms of the detection of pathogens and treatment.@*RESULTS@#Compared with the traditional testing group, the mNGS group had a significantly higher detection rate of pathogens (92% vs 58%, P<0.05), with more types of pathogens and a higher diagnostic rate of mixed infections. Compared with the traditional testing group, the mNGS group had a significantly higher treatment response rate and a significantly lower incidence rate of complications during hospitalization (P<0.05). Treatment was adjusted for 68 children in the mNGS group according to the results of mNGS, with a treatment response rate of 96% (65/68) after adjustment.@*CONCLUSIONS@#Compared with traditional pathogen tests, BALF mNGS can significantly improve the detection rate of pathogens and find some rare pathogens. In clinical practice, when encountering bottlenecks during the diagnosis and treatment of children with RTP, it is advisable to promptly perform the mNGS to identify the pathogens.

ABSTRACT

This paper focuses on the diagnosis and treatment of disorders of laryngeal airway in children, including congenital anomalies, infection, and tumor of the larynx to provide a new technology for managing these diseases. Based on the characteristic of them, the pediatric upper airway is dedicated to the clinical evaluation of airway obstruction and the assessment of the compromised pediatric airway, including clinical evaluation of symptoms, diagnostic endoscopy, and imaging examination. Information on endoscopic techniques used for dealing with different degrees of pediatric airway comprised is provided, also this techniques could diagnose what kinds of airway disorder. For example, determining the a particular laryngeal cleft at the initial otolaryngology encounter, flexible laryngoscopy should be performed. In order to define the extent of any identified cleft, the rigid bronchoscopy should be completed to evaluate for classification of laryngeal cleft including typeⅠ, Ⅱ, Ⅲa, Ⅲb, Ⅳa, Ⅳb under general anesthesia. The decision to pursue any therapy for the disorders of laryngeal airway in children should be based on the severity of the patient's symptoms, endoscopic and imaging examination. There are two medical treatments including nonsurgical therapy and surgical therapy. For example the laryngeal cleft, approximately half of type 1 and select type 2 patients can be managed entirely with nonsurgical therapy. Medical management is multifaceted. Under recommendations from the feeding team, a modified diet with thickened feeds and possibly altered feeding position should be initiated. Endoscopic surgical repair is the current gold standard for definitive repair of type 1, the majority of type 2, and selected type 3 clefts. Finally, information on new techniques used into the future for dealing with the diagnosis and treatment of disorders of laryngeal airway in children in this paper.

ABSTRACT

OBJECTIVES@#To study the role of bronchoscopy in slide tracheoplasty.@*METHODS@#A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty.@*RESULTS@#Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia.@*CONCLUSIONS@#Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.

ABSTRACT

OBJECTIVES@#To study the clinical and bronchoscopic characteristics of tracheobronchial tuberculosis (TBTB) in children and to identify factors influencing residual airway obstruction or stenosis.@*METHODS@#The clinical data of children with TBTB were retrospectively collected. The children were divided into two groups based on the last bronchoscopic result within one year of follow-up: a group with residual airway obstruction or stenosis (n=34) and a group without residual airway obstruction or stenosis (n=58). A multivariate logistic regression analysis was used to identify the factors influencing residual airway obstruction or stenosis in children with TBTB. Receiver operating characteristic (ROC) curves were used to analyze the predictive value of the factors influencing residual airway obstruction or stenosis in children with TBTB.@*RESULTS@#A total of 92 children with TBTB were included, and the main symptoms were cough (90%) and fever (68%). In children under 1 year old, the incidence rates of dyspnea and wheezing were significantly higher than in other age groups (P<0.008). Chest CT findings included mediastinal or hilar lymph node enlargement (90%) and tracheobronchial stenosis or obstruction (61%). The lymphatic fistula type was the main type of TBTB observed bronchoscopically (77%). All children received interventional treatment, and the effective rate was 84%. During one year of follow-up, 34 children had residual airway obstruction or stenosis. The TBTB diagnostic time and the initiation of interventional treatment were significantly delayed in the group with residual airway obstruction or stenosis compared with the group without residual airway obstruction or stenosis (P<0.05). The multivariate logistic regression analysis showed that the TBTB diagnostic time was closely related to residual airway obstruction or stenosis in children (P<0.05). ROC curve analysis showed that at the cut-off value of 92 days of TBTB diagnostic time, the area under the curve for predicting residual airway obstruction or stenosis in children with TBTB was 0.707, with a sensitivity of 58.8% and a specificity of 75.9%.@*CONCLUSIONS@#The clinical manifestations of TBTB are nonspecific, and symptoms are more severe in children under 1 year old. TBTB should be suspected in children with tuberculosis and chest imaging indicating airway involvement. Delayed diagnosis of TBTB is associated with the development of residual airway obstruction or stenosis.

ABSTRACT

Transbronchil biopsy has the characteristic of less trauma and quick recovery compared to percutaneous aspiration biopsy. In order to automate this procedure, it requires the development of a robotic surgical system that combines electromagnetic navigation and flexible endoscope. The robotic surgical system introduced herein consists of flexible endoscope, remote-control handle, electromagnetic navigation and dexterous manipulators. The robotic system supports lung bronchial model segmentation and reconstruction, automatic bronchial path planning, real-time navigation and visual biopsy. In the control of the endoscopic catheter, an elasticity compensation algorithm was proposed to improve the location accuracy of the catheter and operational efficiency. Clinical trials proved that the robotic system had high positioning accuracy, was intuitive to operate, and could improve the biopsy efficiency, shorten the learning time, reduce the burden of surgical operations, and lower radiation exposure and infection rate.

ABSTRACT

BACKGROUND@#The incidence and mortality of lung cancer have always been at the forefront of malignant tumors. With the development of lung cancer detection techniques, more peripheral pulmonary lesions (PPLs) have been detected. The diagnostic accuracy of procedures for PPLs keeps controversial. This study aims to systematically evaluate the diagnostic value and the safety of electromagnetic navigation bronchoscopy (ENB) in the diagnosis of PPLs.@*METHODS@#The relevant literatures in the diagnostic yield of PPLs by ENB were systematically retrieved from Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure, Embase, PubMed, Cochrane Library and Web of Science. The software of Stata 16.0, RevMan 5.4 and Meta-disc 1.4 were used to conduct the meta-analysis.@*RESULTS@#A total of 54 literatures with 55 studies were included in our meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of ENB in the diagnosis of PPLs were 0.77 (95%CI: 0.73-0.81), 0.97 (95%CI: 0.93-0.99), 24.27 (95%CI: 10.21-57.67), 0.23 (95%CI: 0.19-0.28) and 104.19 (95%CI: 41.85-259.37), respectively. The area under curve (AUC) was 0.90 (95%CI: 0.87-0.92). Meta-regression and subgroup analyses indicated that the potential heterogeneity resulted from study type, additional localization techniques, sample size, lesion size and type of sedation. The use of additional localization techniques and general anesthesia have improved the diagnostic efficiency of ENB in PPLs. The incidence of adverse reactions and complications associated with ENB was very low.@*CONCLUSIONS@#ENB provides well diagnostic accuracy and safety.

ABSTRACT

Abstract Mucopolysaccharidosis (MPS) are a group of rare genetic inherited diseases with a progressive course due to the accumulation of glycosaminoglycans resulting in anatomic abnormalities and organ dysfunction, including the respiratory, cardiovascular, skeletal, and neurological systems that can increase the risk of anesthesia complications. Clinical manifestations are variable, multisystemic, and include severe morphological changes. The anesthetic management of these patients is complex, particularly airway management, which can be planned to include a fiberoptic airway investigation prior to surgery. We present two cases of patients with MPS type VI and VII who underwent fiberoptic airway mapping under conscious sedation, with no complications. Since MPS is a rare but challenging disease concerning the airway management, we propose a safe and effective anesthetic technique that could be used for fiberoptic bronchoscopy and allow fiberoptic-assisted tracheal intubation at the time of surgery.

ABSTRACT

El cáncer pulmonar se establece como la segunda causa de muerte en países desarrollados y en algunos en vías de desarrollo. Su diagnóstico es tardío, sus opciones de resección y su curación aun con terapias adyuvantes son limitadas, lo que incide en la pobre sobrevida a 5 años, es por ello que se necesitan mayores esfuerzos para combatir el hábito del tabaco, principal agente etiológico. Material y Métodos: Se trata de un estudio descriptivo transversal en pacientes adultos atendidos de 01 de enero del 2011 al 31 de diciembre del 2021, ingresados al servicio de cirugía del Hospital San Vicente de Guatemala, con diagnósticos de cáncer pulmonar, masa pulmonar, derrame pleural o nódulo pulmonar solitario. Resultados: Se atendieron 202 pacientes con diagnósticos presuntivos de cáncer pulmonar, no encontrando diferencias significativas en relación al sexo. La edad mayormente afectada se estableció entre los 50 y 70 años. Prevalecieron los estadíos IIIA, IIIB y IV basados en los hallazgos clínicos, tomográficos y transoperatorios y solo al 10% se le sometió a una cirugía de resección pulmonar mayor. Los cánceres de células no pequeñas NSCLC fueron reportados en el 68.7% y el adenocarcinoma fue la variedad más frecuente con el 54.95% sobre el 7.29% del epidermoide. La mortalidad a los treinta días se estableció en 2.97%. Conclusión: El adenocarcinoma pulmonar ocupa el primer lugar en la incidencia de los cánceres pulmonares, desplazando así al carcinoma epidermoide popularizado desde la mitad del siglo pasado. Esta tendencia en el cambio histológico está firmemente asociado a las modificaciones en los hábitos del fumar (AU)


Lung cancer is established as the second cause of death in developed countries and in some developing ones. Its diagnosis is late, its resection options and its cure even with adjuvant therapies are limited, which affects the poor survival at 5 years, which is why greater efforts are needed to combat the tobacco habit, the main etiological agent. Material and Methods: This is a cross-sectional descriptive study in adult patients treated from January 1, 2011 to December 31, 2021, admitted to the surgery service of the Hospital San Vicente de Guatemala, with diagnoses of lung cancer, lung mass, effusion pleural or solitary pulmonary nodule. Results: 202 patients with presumptive diagnoses of lung cancer were treated, finding no significant differences in relation to sex and the most affected age was established between 50 and 70 years. Stages IIIA, IIIB, and IV prevailed based on clinical, tomographic, and intraoperative findings, and only 10% underwent major lung resection surgery. NSCLC non-small cell cancers were reported in 68.7% and adenocarcinoma was the most frequent variety with 54.95% over 7.29% of epidermoid. Thirty-day mortality was established at 2.97%. Conclusion: Pulmonary adenocarcinoma occupies the first place in the incidence of lung cancers, thus displacing squamous cell carcinoma popularized since the middle of the last century. This trend in histological change is strongly associated with changes in smoking habits.

ABSTRACT

La purpurina es un pigmento en polvo de cobre, que se utiliza con frecuencia en actividades artesanales y manualidades escolares. La ingestión o inhalación de esta sustancia provoca un cuadro de intoxicación por cobre potencialmente fatal en niños. Se describe el caso de un niño de 15 meses con intoxicación por cobre, que se presenta con dificultad respiratoria aguda, alteración del sensorio y anemia hemolítica. El inicio temprano del tratamiento mediante broncoscopia y lavado bronquial con posterior intubación endotraqueal y ventilación mecánica, lograron la remisión completa del cuadro respiratorio sin secuelas. Ante una ingestión y/o inhalación de purpurina, debe indicarse de inmediato la broncoscopia con lavado bronquial, aún en ausencia de síntomas respiratorios.


Glitter is a powdered copper pigment frequently used in craft and decorative activities especially in schools and kindergartens.Ingestion or inhalation of this substance can cause acute, potentially fatal copper poisoning in children. We describe a case of a 15-month-old child with copper poisoning, presenting with acute respiratory distress, neurological impairment, and hemolytic anemia. Early onset of treatment by bronchoscopy and bronchial lavage with subsequent endotracheal intubation and mechanical ventilation, achieved complete remission of the respiratory symptoms without sequelae. In presence of glitter ingestion or inhalation, bronchoscopy with bronchial lavage should be indicated early even in the absence of respiratory symptoms.

Lung volume reduction loop uses bronchoscopic lung volume reduction(BLVR) technology to compress and collapse the necrotic emphysema tissue and exhaust the internal gas to achieve the purpose of lung volume reduction to treat emphysema. After the lung volume reduction loop is implanted into the human body, the compressed part of the lung tissue tends to expand with breathing, which makes the lung volume reduction loop expand into a linear trend periodically. Fatigue resistance is one of the most important performance indexes of the lung volume reduction loop. In the paper, Z-direction vibration fatigue machine was used to simulate the changes of human respiratory cycle movement to test the fatigue performance of lung volume reduction loop, which can provide some reference for the test method of in vitro fatigue performance of lung volume reduction related products in the future.

ABSTRACT

Lung cancer ranks the first cancer-related morbidity and mortality in China. With the development and penetration of imaging technology, increasing small pulmonary peripheral Nodules (SPPNs) have been detected. However, precise location and diagnosis of SPPNs is still a tough problem for clinical diagnosis and treatment in department of thoracic surgery. With the development of electromagnetic navigation bronchoscopy (ENB), it provides a novel minimally invasive method for the diagnosis and treatment of SPPNs. In this review, we summarized the application and progress of ENB in preoperative positioning, diagnosis, and local treatment, then, discussed the clinical application of ENB in the hybrid operating room.

ABSTRACT

With the popularization of health screening and the widespread use of low-dose computed tomography, the detection rate of lung nodules has increased year after year. However, the false positive rates testified by surgery of these lung nodules are still high. Therefore, it is vital in clinical practice to avoid overtreatment or undertreatment. But a series of problems on how to make an accurate diagnosis, how to reduce the psychological pressure of patients and follow up with regular imaging, how to clarify the indications for surgery and adopt the most minimally invasive diagnosis and treatment methods, etc. remain unsolved. Over the past decade, the diagnostic techniques for pulmonary nodules have improved significantly, including imaging progress such as the optimization of traditional imaging techniques (CT, MRI) and the emergence of new technologies (radiomics, artificial intelligence). In addition, histological improvements including percutaneous transthoracic needle biopsy, bronchoscopy, and minimally invasive surgical biopsy, etc. have brought more reliable and precise options for characterization of pulmonary nodules.

ABSTRACT

Objective: To investigate the clinical manifestation, pathological type, treatment and prognosis of primary lung tumors in children. Methods: We collected and retrospectively analyzed the clinical manifestation, pathological type, therapeutic method and prognosis of 56 primary lung tumors patients who diagnosed from 2009 to 2019 in Guangzhou Women and Children Medical Center. Results: There were 56 patients identified as the primary lung tumors, including pleuropulmonary blastoma (PPB, n=28), pulmonary inflammatory myofibroblastic tumor(IMT, n=20), mucoepidermoid carcinoma(n=6), infantile hemangioma (n=1), pulmonary sclerosing hermangioma(n=1). Respiratory symptoms were the most manifestation at the time of diagnosis including 26 patients with cough, 3 with hemoptysis, and 17 with dyspnea. Others included 15 with fever, 3 with chest pain, and 2 with epigastiric pain. The primary tumor of 18 cases were located in the lower lobe of left lung, 11 cases in the lower lobe of right lung, 10 cases in the upper lobe of left lung, 7 cases in the upper lobe of right lung, 6 cases in the middle lobe of right lung, and 4 cases in pulmonary hilum. Among the 56 patients, 41 patients underwent thoracotomy, 13 thoracoscopy, and 2 fiberoptic bronchoscopy. Five patients with type Ⅰ PPB were still alive at the end of follow-up without chemotherapy. Among 5 patients with type Ⅱ PPB, 2 patients without chemotherapy died after recurrence, 3 patients suffered postoperative chemotherapy were still alive at the end of follow-up. All of the 18 patients with type Ⅲ PPB underwent postoperative chemotherapy with IVADo regimen. Recurrence occurred in 6 cases, distant metastasis occurred in 3 cases, and cancer-related deaths occurred in 8 cases. For 20 patients with IMT, recurrence occurred in 5 of 13 patients experienced wedge resection, 1 of 6 patients experienced lobectomy and 1 of 6 underwent fiberoptic bronchoscopy, respectively. For 6 mucoepidermoid carcinoma patients, lobectomy was carried on 5 patients, wedge resection on 1 patient, all of them were still alive at the end of follow-up. One hermangioma patient underwent fiberoptic bronchoscopy and other 1 sclerosing hermangioma patient underwent wedge resection, both of them were still alive at the end of follow-up. Conclusions: The clinical manifestations of the primary lung tumors in children are nonspecific. Complete resection and achieving negative marginattribute to the excellent outcome. Adjunctive treatment such as chemotherapy is necessary for patients with type Ⅱ and type Ⅲ PPB.
