Evaluación de técnicas mínimamente invasivas en el diagnóstico de enfermedades benignas y malignas del tórax / An Assessment of Minimally Invasive Techniques for the Diagnosis of Benign and Malignant Thoracic Diseases

Introducción: Los cambios en la tecnología médica abarcan todas las especialidades y dentro de ellas, en la cirugía general. Las técnicas mínimamente invasivas han ocupado un papel cimero en el diagnóstico y tratamiento de enfermedades en la cavidad torácica. Objetivo: Describir el uso de las técnicas mínimamente invasivas en el diagnóstico de enfermedades intratorácicas. Métodos: Se realizó un estudio observacional, retrospectivo de corte transversal para evaluar el uso de técnicas mínimamente invasivas en el diagnóstico de las enfermedades intratorácicas en el Hospital Universitario "Manuel Ascunce Domenech" desde enero de 2017 hasta mayo de 2020. El universo estuvo compuesto por 104 pacientes con sospecha diagnóstica de enfermedades benignas o malignas del tórax. Resultados: La mayor parte de los pacientes con enfermedades benignas y malignas del tórax tenían una edad de 49 (±7,05) años, sin significación intersexo. La hipertensión arterial predominó como principal comorbilidad. La videotoracoscopia fue la técnica mínimamente invasiva más empleada y la sospecha de cáncer pulmonar y enfermedad pleural constituyeron las indicaciones más frecuentes que motivaron el proceder. El diagnóstico posoperatorio que predominó en la serie fue el cáncer pulmonar. Las técnicas mínimamente invasivas empleadas mostraron una alta validez. La mayoría de los pacientes egresaron vivos y sin complicaciones. Conclusiones: El uso de técnicas mínimamente invasivas en varias enfermedades intratorácicas son de vital importancia para definir diagnóstico y tratamiento(AU)

Introduction: Changes in medical technology cover all specialties and, within them, general surgery. Minimally invasive techniques have played a paramount role in the diagnosis and treatment of thoracic cavity diseases. Objective: To describe the use of minimally invasive techniques in the diagnosis of intrathoracic diseases. Methods: An observational, retrospective and cross-sectional study was carried out, from January 2017 to May 2020, in order to assess the use of minimally invasive techniques in the diagnosis of intrathoracic diseases at Manuel Ascunce Domenech University Hospital. The universe was made up of 104 patients with suspected benign or malignant diseases of the chest. Results: Most of the patients with benign and malignant chest diseases were 49 (± 7.05) years old, without intersex significance. Arterial hypertension predominated as the main comorbidity. Videothoracoscopy was the most widely used minimally invasive technique, while suspicion of lung cancer and pleural disease were the most frequent indications that motivated the procedure. The postoperative diagnosis that predominated in the series was lung cancer. The minimally invasive techniques used showed high validity. Most of the patients were discharged alive and without complications. Conclusions: The use of minimally invasive techniques in various intrathoracic diseases are of vital importance to define diagnosis and treatment(AU)

Type 2 Myocardial Infarction Resulted from the Left Thoracic Stomach.

The universal definition of myocardial infarction (MI) provides five subtypes of acute myocardial infarction (AMI). We present an interesting case of a type 2 myocardial infarction caused by the dilation of the left thoracic stomach.

Radiography and computed tomography of the heart and lower respiratory tract in toco toucans (Ramphastos toco).

This study aimed to evaluate normal features of the heart and lower respiratory tract in toco toucans by means of radiography and helical computed tomography (CT) scanner. Fifteen healthy adult toco toucans (Ramphastos toco), 10 females and 5 males, average body mass of 650 g were studied. CT examination as well as right lateral and ventrodorsal radiographic examinations of the coelomic cavity were performed under chemical restraint. Heart, lungs, air sacs, trachea and syrinx were analysed. The mean values of heart length, heart width and thoracic cavity in radiographs were, respectively, 23.76 mm, 25.94 mm and 48.87 mm. In both X-rays and CT scans, the lung parenchyma had honeycomb-like pattern. The topographic areas of the anterior and posterior air sacs were visualized as dark and air-filled spaces in X-rays. On CT evaluation, the air sacs occupied a larger area in the coelomic cavity compared to X-ray. In the lateral radiographic view, the cervical part of the trachea was positioned more ventrally in the transition from cervical to thoracic regions showing a V-shaped appearance. In all CT planes was visible division of the trachea into the right and left main bronchi at the level of 3rd thoracic vertebra. The syrinx was difficult to visualize in X-rays, but on CT it was easily identified in axial slice. In conclusion, the normal features of toco toucan's heart and lower respiratory tract that were determined on X-rays and CT scans are useful to compare with sick toco toucans, as well as other bird species.
