Robotic esophagectomy with function-preserving radical mediastinal lymphadenectomy for esophageal cancer.
Ann Gastroenterol Surg
January 2025
Radical lymphadenectomy is the critical component of surgery for esophageal cancer. However, lymphadenectomy significantly contributes to postoperative morbidity, particularly in terms of pulmonary complications following esophagectomy. Function-preserving mediastinal lymphadenectomy seeks to balance the procedure's necessary radicality and optimal functional outcomes.

Tracheobronchial amyloidosis is a rare condition characterized by the deposition of amyloid proteins in the trachea and bronchi, leading to significant respiratory symptoms such as chronic mucoid, cough, dyspnea, and recurrent respiratory infections. We present the case of a 61-year-old individual who developed tracheobronchial amyloidosis, which poses a diagnostic challenge due to its clinical and radiological resemblance to other pulmonary disorders, including chronic bronchitis. Histologically, tracheobronchial amyloidosis is characterized by the presence of amyloid deposits confirmed by Congo red staining, which shows apple-green birefringence under polarized light.

Pulmonary sequestrations comprise a spectrum of congenital lung malformations, with abnormal lung tissue lacking connection with the tracheobronchial tree, supplied by an aberrant systemic artery. Until a few years ago, lobectomy was considered the standard treatment for intralobar pulmonary sequestration. However, minimally invasive sublobar resection gained a place as an interesting alternative therapeutic approach, guided by indocyanine green and computed tomography-based 3-dimensional anatomical models.

Article Synopsis
- A study was conducted to assess the effectiveness of a specific MRI technique (delayed 3D IR FLASH) in evaluating the lower airways of children during routine cardiovascular magnetic resonance imaging.
- The study included 180 pediatric patients, with a high image quality rating and visibility of lower airways; around 21% of patients showed lower airway abnormalities, particularly among those with congenital heart disease.
- The results suggest that this MRI method is highly reliable and effective for viewing lower airway anatomy, enhancing the potential for identifying issues in children with heart conditions.
The reliability and accuracy of numerical models and computer simulations to study aerosol deposition in the human respiratory system is investigated for a patient-specific tracheobronchial tree geometry. A computational fluid dynamics (CFD) model coupled with discrete elements methods (DEM) is used to predict the transport and deposition of the aerosol. The results are compared to experimental and numerical data available in the literature to study and quantify the impact of the modeling parameters and numerical assumptions.
