High incidence of tracheobronchial diverticulum in esophageal cancer patients: a retrospective survey alerting pitfall during thoracoscopic esophagectomy
ConclusionSince tracheobronchial DVs are not as rare as previously thought, careful evaluation of thin-slice CT scans is necessary before thoracoscopic esophagectomy. If a tracheobronchial DV is injured during surgery, it is important to carefully repair it and confirm that there is no air leak to avoid complications.

Endoscopic resection of tracheal lobular capillary haemangioma with ultrasonically activated device
We reported the case of a 55-year-old man with a large tracheal lobular capillary haemangioma attached to posterior tracheal wall and successfully managed with arterial embolization followed by endoscopic resection using Harmonic ™ ACE Plus. Because of the high risk of bleeding, Harmonic™ was used in this case due to its ability to cut and cauterize simultaneously. The instrument jaw repeatedly grasped the attachment point of tumor, and then the cavitation effect, created by the longitudinal vibration of the blade tip, s eparated it from the posterior tracheal wall, reducing the risk of perforation. Yet, the ul...

Hybrid surgical resection of a tumor invading the superior vena cava
AbstractRecently, hybrid operations featuring vascular interventions have become more common, but applications in the thoracic surgery are few. Superior vena cava (SVC) resection and reconstruction is a typical complex thoracic surgery. Traditional SVC resection/reconstruction requires advanced vascular surgical skills. We developed a simple and safe procedure; we insert a stent during malignant tumor surgery involving the SVC. This approach renders such surgery easier, increasing the probability of success.

Management of congenital lobar overinflation in an adult
AbstractCongenital lobar overinflation is characterized by disruption of bronchopulmonary development which produces lobar or segmental bronchial abnormalities and overinflation of normal lung tissue. This is a 44-year old man, never smoker, who presents dyspnea every time he arrived in highlands, marked decreased breathing sounds and hyperresonance in the left hemithorax. Imaging studies suggested left upper lobe overinflation. The affected area was resected resulting in symptoms improvement. Accepted treatment is resection, however conservative management has been proposed for asymptomatic patients because cases of spont...

Three-dimensional reconstruction computed tomography demonstrated a feeding artery from the pulmonary artery draining into the pulmonary vein. We diagnosed her with extralobar sequestration and resected the sequestered lung using video-assisted thoracic surgery. Therefore, three-dimensional reconstruction computed tomogr...

Sentinel lymph node biopsy for lung cancer
AbstractSentinel lymph node biopsy is a technique to identify the first lymph node (or nodes) draining a tumor. The underlying principle is that as the first site of cancer spread, evaluation of the sentinel node will be most predictive for wider nodal involvement. The introduction of sentinel node biopsy revolutionized the surgical management of cutaneous melanoma and breast cancer, becoming a key component in the management of such patients. For over 20  years, thoracic surgeons have similarly worked to apply this technique to lung cancer but have thus far not had the same impact on lung surgery. In this review, we ...
