Introduction: Altered lipid metabolism has been reported to be associated with prognosis in multiple cancers. This study aimed to investigate the association of polymorphisms in lipid metabolism pathway genes with survival outcomes in patients with surgically resected non-small cell lung cancer (NSCLC).

Methods: In total, 744 patients with surgically resected NSCLC (380 in the discovery cohort and 364 in the validation cohort) were included in this study.

Anesthetic management for inhibiting sympathetic activation in an adolescent patient diagnosed with catecholaminergic polymorphic ventricular tachycardia and undergoing left cardiac sympathetic denervation: A case report.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a genetic disorder in which catecholamine release during exercise or emotional stress cause fatal tachyarrhythmias. In this paper, we discuss methods to minimize the sympathetic stimulation that can occur during the perioperative period in patients undergoing left cardiac sympathetic denervation to surgically treat CPVT.

Ultrasound-guided lung biopsy for small (≤2 cm) subpleural lung lesions: comparison of diagnostic yield and safety with larger lesions.

Background: Ultrasound (US)-guided percutaneous core needle biopsy (PCNB) has been used to diagnose subpleural lung lesions with high diagnostic performance and acceptable complication rates. However, with regard to the role of US-guided needle biopsy for the diagnosis of small (≤2 cm) subpleural lesions, limited information is available.

Methods: From April 2011 to October 2021, a total of 572 US-guided PCNBs in 572 patients were retrospectively reviewed.

Effect of Minimum Bronchial Cuff Volume of Left-Sided Double-Lumen Tube for One-Lung Ventilation on the Change in Bronchial Cuff Pressure during Lateral Positioning in Thoracic Surgery: A Prospective Observational Study.

The minimum bronchial cuff volume (BCVmin) of a double-lumen tube (DLT) without air leaks during lung isolation may vary among individuals, and lateral positioning could increase the bronchial cuff pressure (BCP). We investigated the effect of initially established BCVmin (BCVi) on the change in BCP by lateral positioning. Seventy patients who underwent elective lung surgery were recruited and divided into two groups according to the BCVi obtained during anesthetic induction in each patient.

Clinical implication of minimal presence of solid or micropapillary subtype in early-stage lung adenocarcinoma.

Background: We investigated the clinical features and surgical outcomes of lung adenocarcinoma with minimal solid or micropapillary (S/MP) components, with a focus on stage IA.

Methods: We enrolled 506 patients with lung adenocarcinoma who underwent curative resection in this study. Clinical features and surgical outcomes were compared between the groups with and without the S/MP subtype (S/MP+ and S/MP-, respectively), and between the group with an S/MP proportion of ≤5% (S/MP5) and the S/MP-.

Ultrasound-Guided Percutaneous Needle Biopsy for Small Pleural Lesions: Diagnostic Yield and Impact of CT and Ultrasound Characteristics.

Ultrasound (US)-guided percutaneous pleural needle biopsy (PCPNB) is widely used to evaluate pleural lesions, although its diagnostic accuracy is variable. The purpose of this study is to assess the diagnostic yield of US-guided PCPNB for small (≤ 2 cm) pleural lesions and the impact of CT and US morphologic and technical factors. A total of 103 patients (73 men and 30 women; mean [± SD] age, 68.

Genetic Variants in One-Carbon Metabolism Pathway Predict Survival Outcomes of Early-Stage Non-Small Cell Lung Cancer.

Background: This study was conducted to investigate the association between genetic variants in one-carbon metabolism and survival outcomes of surgically resected non-small cell lung cancer (NSCLC).

Methods: We genotyped 41 potentially functional variants of 19 key genes in the one-carbon metabolism pathway among 750 NSCLC patients who underwent curative surgery. The association between genetic variants and overall survival (OS)/disease-free survival (DFS) were analyzed.

Transpedal lymphatic embolization for lymphorrhea at the graft harvest site after coronary artery bypass grafting.

Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there is no standard effective treatment.

Idiopathic Pleural Effusions: Characteristics and Discrimination From Cytology-Negative Malignant Pleural Effusions.

Background: The etiology of pleural effusions often remained unknown notwithstanding surgical pleural biopsy and further clinical observation. A better understanding of clinical characteristics of patients with idiopathic pleural effusion (IPE) may improve the ability to differentiate between IPEs and cytology-negative malignant pleural effusions (MPEs) and facilitate the identification of patients requiring invasive investigation. However, little is known about the clinical factors that can help distinguish patients with IPE from those with cytology-negative MPE.

Characteristics and survival impact of polymorphonuclear leucocyte-predominant malignant pleural effusions secondary to lung cancer.

Introduction: In comparison with mononuclear leucocyte (MNL)-predominant malignant pleural effusions (MPEs), polymorphonuclear leucocyte (PMNL)-predominant MPEs have rarely been investigated and may be associated with a poorer prognosis.

Objectives: To investigate the characteristics and survival impact of PMNL-predominant MPEs secondary to lung cancer.

Methods: This retrospective study included patients with MPE secondary to lung cancer, which were classified into the PMNL- and MNL-predominant groups according to cellular predominance in the pleural fluid.

Over-the-wire deployment techniques of option elite inferior vena cava filter: 3D printing vena cava phantom study.

Purpose: To compare filter tilt and filter jumping during Option inferior vena cava (IVC) filter deployment with 3 different wires techniques using a 3-dimensional (3D) printing vena cava phantom.

Materials And Methods: An IVC 3D printed vena cava phantom was made from a healthy young male's computed tomographic data. Option IVC filters were deployed with 3 different wires: i) original push wire, ii) hydrophilic stiff wire, and iii) bent stiff wire.

Serratus Anterior Plane Block and Intercostal Nerve Block after Thoracoscopic Surgery.

Background:  This study aimed to compare the postoperative analgesic effect between ultrasound-guided serratus anterior plane block (Group S, SAPB) and intercostal nerve block (Group I, ICNB) after single port video-assisted thoracoscopic surgery (S-VATS) in primary spontaneous pneumothorax.

Methods:  In this prospective randomized controlled study, 54 patients were randomly assigned to two groups. Patients in Group S underwent the SAPB before the surgical drape by an anesthesiologist, and in Group I, ICNBs were performed just before the wound closure after S-VATS by an attending thoracic surgeon.

Traumatic Right Pulmonary Artery Rupture after Accidentally Being Stepped on the Chest.

Traumatic pulmonary artery rupture is a rare, life-threatening injury. Currently, no strict guidelines for its management exist. Herein, we report a successful surgical repair of a right pulmonary artery rupture caused by being stepped on.

Thoracic aortic aneurysms exerting high extrinsic pressure on the airway.

Background: Thoracic aortic aneurysms, although mostly asymptomatic, are life threatening owing to the risk of rupture. Moreover, the extrinsic pressure of a ruptured aneurysm may encroach the mediastinum.

Case Presentation: A 74-year-old woman diagnosed with ruptured descending thoracic aortic aneurysm compressing the lower trachea and both main bronchi underwent thoracic endovascular aortic repair; however, the extrinsic pressure on the airway persisted.

Under-recognized primary spontaneous pneumothorax in ALS: a multicenter retrospective study.

Primary spontaneous pneumothorax (PSP) is not an uncommon disease, especially in patients with risk factors such as male gender, history of smoking, and low body mass index (BMI). Amyotrophic lateral sclerosis (ALS) is a rare disease caused by neurodegeneration of the motor neurons that share risk factors with PSP. The aim of this study was to determine the prevalence of PSP in ALS and find the significant risk factors related to PSP.

Mid-term outcomes of endovascular repair for traumatic thoracic aortic injury: a single-center experience.

Purpose: Thoracic endovascular aortic repair (TEVAR) for traumatic thoracic aortic injury (TTAI) reports short-term benefits. However, long-term durability and the need of reintervention remain unclear. Here, we determined mid-term outcome of TEVAR for TTAI and investigated the influence of the length of proximal landing zone on aorta.

Successful Treatment Using Endoluminal Vacuum Therapy after Failure of Primary Closure in Boerhaave Syndrome.

Boerhaave syndrome is a transmural perforation of the esophagus and typically occurs after forceful emesis. Boerhaave syndrome is a destructive disease with a high mortality rate, though surgical intervention within 24 hours has a beneficial effect. On the other hand, late surgical intervention is associated with poorer prognoses.

Complete resection of primary pulmonary malignancy extending into the left atrium via the left pulmonary vein using cardiopulmonary bypass and single incision: A case series.

If the best treatment for a patient with a primary pulmonary tumor extending into the left atrium via the left pulmonary vein is surgical resection, it is necessary to determine the appropriate approach, that is, whether cardiopulmonary bypass (CPB) or complete resection, would be more suitable. Lung resections under CPB are rarely performed because of the unpredictable prognosis. We report two successful cases of safe and rapid complete resection of primary pulmonary malignancy extending into the left atrium with the support of CPB via median sternotomy.

Infarction of torsed extralobar pulmonary sequestration in adolescence.

Torsion of pulmonary extralobar sequestration is extremely rare in childhood and adolescence, and as it presents with a variety of symptoms ranging from intermittent pain to fever from infarction, differential diagnosis is necessary. Herein, we report a rare case of 13-year-old girl who presented with abdominal pain and fever was diagnosed as infarction of torsed extralobar pulmonary sequestration. Torsed extralobar pulmonary sequestration was removed by thoracoscopic surgery, and the patient remained in good clinical condition.
