Airway Complications after Lung Transplantation-A Contemporary Series of 400 Bronchial Anastomoses from a Single Center.

(1) Objective: To determine whether recent advances in lung transplantation (LT) have reduced the incidence and changed the risk factors for airway complications (AC). (2) Methods: Retrospective analysis of patients receiving a lung transplant between January 2007 and January 2019. An AC was defined as a bronchoscopic abnormality in the airway, either requiring or not requiring an endoscopic or surgical intervention. Both univariable and multivariable analyses were performed to identify risk factors for AC. (3) Results: 285 lung transplants (170 single and 115 bilateral lung transplants) were analysed, comprising 400 anastomoses at risk. A total of 50 anastomoses resulted in AC (12%). There were 14 anastomotic and 11 non-anastomotic stenoses, 4 dehiscences, and 3 malacias. Independent predictors for AC were: gender male (OR: 4.18; p = 0.002), cardiac comorbidities (OR: 2.74; p = 0.009), prolonged postoperative mechanical ventilation (OR: 2.5; p = 0.02), PaO2/FiO2 < 300 mmHg at 24 h post-LT (OR: 2.48; p = 0.01), graft infection (OR: 2.16; p = 0.05), and post-LT isolation of Aspergillus spp. (OR: 2.63; p = 0.03). (4) Conclusions: In spite of advances in lung transplantation practice, the risk factors, incidence, and lethality of AC after LT remains unchanged. Graft dysfunction, an infected environment, and the need of prolonged mechanical ventilation remain an Achilles heel for AC.

Routinely ultrasound surveillance improves outcome after endovascular treatment of peripheral arterial disease: propensity-matched comparisons of clinical outcomes after ultrasound or clinical-hemodynamic based surveillance programs.

BACKGROUND: Endovascular treatment (EVT) has replaced open repair as the first option in intermittent claudication (IC) and chronic limb-threatening ischemia (CLTI) in several centers. However, evidence of the most optimal post-procedural surveillance strategy is sparse. This study aimed to compare two routine surveillance programs after EVT of IC/CLTI: clinical and hemodynamic assessment (CHA) vs. duplex ultrasound (DUS) and clinical/hemodynamic assessment in combination. METHODS: Between February 2012 and December 2015, all patients with EVT of IC/CLTI were allocated to either CHA or DUS-based routine surveillance programs. The allocation-ratio was 1:2 (CHA:DUS), and propensity score matching (PSM) was used to control baseline differences between the groups. Follow-up visits in the CHA group consisted of clinical assessment and ABI at 3, 6, 12 and 24 months. Follow-up visits in DUS group consisted of clinical assessment, ABI, and target vessel DUS at 1, 3, 6, 12, 18 and 24 months. RESULTS: In total, 340 legs in 305 patients suffering from IC/CLTI were included; 111 (33%) in the CHA-group and 229 (67%) in the DUS group. The two groups were identical except for a significantly lower incidence of diabetes mellitus in the CHA group than the DUS group, 55% vs. 72%, respectively (P=006). Based on PSM, the CHA-group vs. the DUS-group was burdened of an increased risk of amputation (12.5% vs. 8.27%, HR=0.41 [95% CI: 0.17-0.96]), and a higher mortality (21.2% vs. 12.8%, HR=0.37 [95% CI: 0.19-0.72]). The reported differences in reintervention rate (7.5% vs. 12.8%, HR=1.12 [95% CI: 0.44-2.84]) were insignificant. The mean follow-up was 317 days (SD=0.214) in the CHA group and 611 days (SD=0.298) in the DUS group. CONCLUSIONS: Our results suggest that DUS-based routine surveillance after EVT of IC/CLTI is superior to CHA-based routine surveillance in improved amputation rate and mortality.

Role of Botulinum Toxin in Pectoralis Minor Syndrome.

BACKGROUND: Thoracic outlet syndrome (TOS) causes neurogenic symptoms in 95% of the cases due to neurovascular bundle compression. The treatment goal is the decompression of the neurovascular structures. In the last decade, non-surgical treatments have been evaluated as a treatment option for spastic syndromes and thoracic outlet syndrome. In this study we report the use of botulinum toxin (BTX-A) injection as a diagnostic tool to identify the pectoral minor syndrome, and as a less aggressive treatment-option. METHODS: An observational cohort study of patients with neurogenic thoracic outlet syndrome who underwent sonographically guided chemodenervation of pectoral minor muscle with botulinum toxin. Follow-up includes clinical evaluation at one month, 3 months and 6 months after the procedure. Clinical evaluation was made with clinical questionnaire. In case of patients with partial improvement of the symptoms, a second infiltration of BTX-A was performed. The categorical variables were shown as percentages, and the continuous variables as mean and standard deviation (SD). For the comparison of categorical variables, the Fisher's exact test was used. Statistical analysis was performed using the SPSS version 20.0 program. We consider P <0.05 to be statistically significant. RESULTS: A total of twenty-six patients were diagnosed with thoracic outlet syndrome in this period, and 20 accomplished the inclusion criteria. 7 patients were excluded (1 due to neoplasia, 2 did not sign the informed consent, 1 due to neoplasia, 2 did not sign the informed consent, 1 was lost during the follow-up and 3 due to anomalies of the first rib secondary to fractures and cervical rib and 1 was lost during the follow-up), therefore a sample of 13 patients aged between 24 and 55 years was obtained. The most common type of procedure performed was the single injection of 50 IU of botulinum toxin. 4 patients were infiltrated in 2 occasions due to partial improvement in symptoms at 1month follow-up. Clinical stability was found at three months and at 6 months follow-up. CONCLUSION: The ultrasound-guided botulinum injection of the pectoralis minor muscles provides symptoms relief in patients with pectoral minor syndrome, and could be considered a safe tool in the diagnosis of the pectoralis minor syndrome within the spectrum of thoracic operculum syndrome.

Surgical Risk Following Anatomic Lung Resection in Thoracic Surgery: A Prediction Model Derived from a Spanish Multicenter Database. / Riesgo quirúrgico tras resección pulmonar anatómica en cirugía torácica. Modelo predictivo a partir de una base de datos nacional multicéntrica.

INTRODUCTION: The aim of this study was to develop a surgical risk prediction model in patients undergoing anatomic lung resections from the registry of the Spanish Video-Assisted Thoracic Surgery Group (GEVATS). METHODS: Data were collected from 3,533 patients undergoing anatomic lung resection for any diagnosis between December 20, 2016 and March 20, 2018. We defined a combined outcome variable: death or Clavien Dindo grade IV complication at 90 days after surgery. Univariate and multivariate analyses were performed by logistic regression. Internal validation of the model was performed using resampling techniques. RESULTS: The incidence of the outcome variable was 4.29% (95% CI 3.6-4.9). The variables remaining in the final logistic model were: age, sex, previous lung cancer resection, dyspnea (mMRC), right pneumonectomy, and ppo DLCO. The performance parameters of the model adjusted by resampling were: C-statistic 0.712 (95% CI 0.648-0.750), Brier score 0.042 and bootstrap shrinkage 0.854. CONCLUSIONS: The risk prediction model obtained from the GEVATS database is a simple, valid, and reliable model that is a useful tool for establishing the risk of a patient undergoing anatomic lung resection.

Spanish Video-Assisted Thoracic Surgery Group: Method, Auditing, and Initial Results From a National Prospective Cohort of Patients Receiving Anatomical Lung Resections / Grupo Español de Cirugía Torácica Videoasistida: Método, Auditoría y Resultados Iniciales de una Cohorte Nacional Prospectiva de Pacientes Tratados con Resección Pulmonar Anatómica

INTRODUCTION: Our study sought to know the current implementation of video-assisted thoracoscopic surgery (VATS) for anatomical lung resections in Spain. We present our initial results and describe the auditing systems developed by the Spanish VATS Group (GEVATS). METHODS: We conducted a prospective multicentre cohort study that included patients receiving anatomical lung resections between 12/20/2016 and 03/20/2018. The main quality controls consisted of determining the recruitment rate of each centre and the accuracy of the perioperative data collected based on six key variables. The implications of a low recruitment rate were analysed for "90-day mortality" and "Grade IIIb-V complications". RESULTS: The series was composed of 3533 cases (1917 VATS; 54.3%) across 33 departments. The centres' median recruitment rate was 99% (25-75th:76-100%), with an overall recruitment rate of 83% and a data accuracy of 98%. We were unable to demonstrate a significant association between the recruitment rate and the risk of morbidity/mortality, but a trend was found in the unadjusted analysis for those centres with recruitment rates lower than 80% (centres with 95-100% rates as reference): grade IIIb-V OR = 0.61 (p = 0.081), 90-day mortality OR = 0.46 (p = 0.051). CONCLUSIONS: More than half of the anatomical lung resections in Spain are performed via VATS. According to our results, the centre's recruitment rate and its potential implications due to selection bias, should deserve further attention by the main voluntary multicentre studies of our speciality. The high representativeness as well as the reliability of the GEVATS data constitute a fundamental point of departure for this nationwide cohort

INTRODUCCIÓN: Nuestro estudio buscó conocer el grado de implementación actual de la cirugía toracoscópica asistida por video (VATS, por sus siglas en inglés) para las resecciones pulmonares anatómicas en España. Presentamos nuestros resultados iniciales y describimos los sistemas de auditoría desarrollados por el grupo español de VATS (GEVATS). MÉTODOS: Realizamos un estudio de cohortes prospectivo multicéntrico que incluyó pacientes que fueron tratados con resecciones pulmonares anatómicas entre el 20/12/2016 y el 20/03/2018. Los controles de calidad principales consistieron en determinar la tasa de reclutamiento de cada centro y la precisión de los datos perioperatorios recolectados en base a seis variables clave. Se analizaron las implicaciones de una baja tasa de reclutamiento para "mortalidad a los 90 días" y "complicaciones de grado IIIb-V". RESULTADOS: La serie estaba compuesta por 3533 casos (1917 VATS; 54,3%) en 33 servicios. La mediana de la tasa de reclutamiento de los centros fue del 99% (p25-p75: 76-100%), con una tasa de reclutamiento global del 83% y una precisión de los datos del 98%. No pudimos demostrar una asociación significativa entre la tasa de reclutamiento y el riesgo de morbi-mortalidad, pero se encontró una tendencia en el análisis no ajustado para aquellos centros con tasas de reclutamiento inferiores al 80% (usando los centros con tasas de 95-100% como referencia): OR = 0,61 para el grado IIIb-V (p = 0,081), OR = 0,46 para la mortalidad a los 90 días (p = 0,051). CONCLUSIONES: Más de la mitad de las resecciones pulmonares anatómicas en España se realizan a través de VATS. Según nuestros resultados, la tasa de reclutamiento del centro y sus posibles implicaciones debido al sesgo de selección, deberían recibir más atención por parte de los principales estudios multicéntricos voluntarios de nuestra especialidad. La alta representatividad y la confiabilidad de los datos de GEVATS constituyen un punto de partida fundamental para esta cohorte nacional

Guidelines on surgery of the thoracic sympathetic nervous system.

Thoracic sympathetic nervous system (TSNS) surgery has increased in importance in the last few years, generating great expectations among the general population and the scientific community. This has been due to the excellent results obtained by videothoracoscopy-assisted thoracic sympathectomy in the treatment of essential hyperhidrosis and other TSNS disorders. This minimally invasive surgical technique has been shown to be effective, and with a low morbidity it is accepted as one of the best therapeutic options for the treatment of palmar and bilateral axillary hyperhidrosis and the number of patients consulting with the intention of having the operation has increased considerably. Although compensatory sweating, which is occasionally intense, often occurs after the surgery, this and other secondary effects of the technique are well tolerated by patients. The current evidence on TSNS and the treatment of essential hyperhidrosis is based on observational studies, making it difficult to compare series and draw conclusions. There has been much discussion on standardising the technique, defining the most favourable levels for clipping, and choosing the type of denervation with least secondary effects. This has led to the need to draw up these guidelines which should clarify and standardise the criteria for managing patients with disorders of TSNS.

La cirugía del sistema nervioso simpático torácico (SNST) ha experimentado un gran auge en los últimos años, generando gran expectación entre la población general y la comunidad científica. Esto se ha debido a los excelentes resultados que ha obtenido la simpatectomía torácica por videotoracoscopia en el tratamiento de la hiperhidrosis esencial y en otros trastornos del SNST.Esta técnica de cirugía mínimamente invasiva ha demostrado ser efectiva y con baja morbilidad, aceptada como una de las mejores opciones terapéuticas para el tratamiento de la hiperhidrosis palmar y axilar bilateral, viéndose incrementado de manera considerable el número de pacientes que consultan con intención de operarse.Aunque la sudoración compensadora, intensa en ocasiones, aparece con gran frecuencia tras la cirugía, éste y otros efectos secundarios de la técnica son bien tolerados por los pacientes.La evidencia actual respecto a la cirugía del SNST y del tratamiento de la hiperhidrosis esencial se basa en estudios observacionales, haciendo difícil comparar series y extraer conclusiones. Se ha discutido mucho para unificar la técnica, definir los niveles de sección más favorables y elegir el tipo de denervación con menos efectos secundarios. Este hecho crea la necesidad de elaborar esta normativa que clarifique y unifique criterios para el manejo de los pacientes con trastornos del SNST(AU)

Syncope and facial blushing due to giant intrapulmonary bronchogenic cyst.

A 43-year-old man presented with dizziness, head instability, and facial reddening, always in relation to body posture and without fever or systemic manifestations. Chest radiography revealed a large cavity with an air-fluid level in the right upper hemithorax. A right upper lobectomy was performed to remove a large bronchogenic cyst. The presentation with cardiac but no respiratory symptoms is uncommon but should be considered in the differential diagnosis of patients with intrathoracic cysts.

Rotura traqueal yatrogénica por intubación orotraqueal / Iatrogenic tracheal rupture after endotracheal intubation

Las laceraciones traqueobronquiales traumáticas postintubación son una complicación clínica poco frecuente en la práctica diaria. Se han relacionado con intentos repetitivos de intubación e hiperinsuflación del balón, así como con alteraciones anatómicas y factores individuales que puedan predisponerla. El diagnóstico se obtiene, actualmente, mediante la endoscopia respiratoria, ya que informa sobre su localización y la extensión lesional. Presentamos el caso de una paciente con laceración de la cara posterior traqueal secundaria a intubación endotraqueal que comenzó con enfisema mediastínico subcutáneo y neumotórax bilateral en el postoperatorio inmediato. El diagnóstico se realizó mediante fibrobroncoscopia y tomografía computarizada y requirió cirugía traqueal de urgencia (AU)

Tracheobronchial rupture after tracheal intubation is rare in clinical practice. Possible contributory factors are multiple vigorous attempts at intubation, overinflation of the cuff, anatomic alterations, and predisposing individual factors. These lesions can be detected by bronchoscopy, which is the most effec-tive method to confirm the diagnosis and determine the exact location and extent of the tear. We report the case of a woman with membranous tracheal rupture after endotracheal intubation. Subcutaneous emphysema, pneumomediastinum and bilateral pneumothorax were noted after extubation. The diagnosis was confirmed by fiberoptic bronchoscopy and computed tomography scan, and the patient required emergency surgical repair (AU)
