Lung cancer, a leading cause of cancer-related death, often requires surgical resection for early-stage cases, with recent data supporting less invasive resections for tumors smaller than 2 cm. Central to resection is lymph node assessment, an area of controversy worldwide, compounded by advances in minimally invasive techniques. The review aims to assess current standards for lymph node assessment, recent data from the surgical era, and the immunobiological basis of how lymph node metastases impact patient outcomes...

BACKGROUND: The inflation-deflation (ID) method has long been the standard for intraoperative margin assessment in segmentectomy. However, with advancements in vision technology, the use of near-infrared mapping with indocyanine green (ICG) has become increasingly common. This study was conducted to compare the perioperative outcomes and resection margins achieved using these methods. METHODS: This retrospective study included patients who underwent direct segmentectomy for clinical stage I lung cancer between January 2018 and September 2022...

AIMS: Radiotherapy is a well-known local treatment for spinal metastases. However, in the presence of postoperative systemic therapy, the efficacy of radiotherapy on local control (LC) and overall survival (OS) in patients with spinal metastases remains unknown. This study aimed to evaluate the clinical outcomes of post-surgical radiotherapy for spinal metastatic non-small-cell lung cancer (NSCLC) patients, and to identify factors correlated with LC and OS. METHODS: A retrospective, single-centre review was conducted of patients with spinal metastases from NSCLC who underwent surgery followed by systemic therapy at our institution from January 2018 to September 2022...

OBJECTIVE: Chemoradiation followed by esophagectomy is a standard treatment option for locally advanced esophageal cancer (LAEC) patients. Esophagectomy is a high-risk procedure, and recent evidence suggests select patients may benefit from omitting or delaying surgery. This study aims to compare surgery versus active surveillance for LAEC patients with complete clinical response (cCR) after neoadjuvant chemoradiotherapy (nCRT). METHODS: Decision analysis with Markov modelling was utilized...

The treatment of traumatic rib fractures and sternal fractures have focused on pain and respiratory management, and conservative treatment has been recommended. Recently, however, a number of case series from abroad have been reported and demonstrated the usefulness of surgical stabilization of rib fractures (SSRF) and sternal fractures (SSSF). We have experienced seven cases of SSRF and two cases of SSSF at International University Health and Welfare Narita Hospital and Atami Hospital. Based on our experienced cases, we have outlined the preoperative evaluation, indication for surgery, timing of surgery, surgical techniques, and postoperative course...

In case that met several indication criteria with 4 or more rib fractures, we performed surgical stabilization of multiple fractured ribs using a plate and screw system( Super FIXORB MX) that was made of uncalcined hydroxyapatite (u-HA)/poly-L-lactic acid (PLLA) composite material with excellent bioactivity and absorbability. We report our clinical experience of 7 cases in which this device was used. Although there is still room for further consideration of the technique and the strength of the device itself, computed tomography( CT) images taken 9 months after surgery showed that the fixative device was almost assimilated with the bone at the fracture repair site in cases where fixation was successful...

We summarized the experience of surgical stabilization of rib fractures (SSRF) at a core hospital in eastern Hiroshima, which is a primary center for tertiary emergency medical care, especially for high-energy trauma cases including chest injuries. The study focuses on patients who underwent SSRF from January 2016 to September 2023, analyzing patient characteristics, injury mechanisms, associated injuries, fracture locations, time from injury to surgery, fixation devices used, and postoperative outcomes. Our hospital primarily treats elderly patients, and falls are the most common cause of injury, followed by traffic accidents...

BACKGROUND: Intra-thoracic organ bleeding and chest wall injury following chest trauma can easily lead to life-threatening emergencies and a delay in treatment may lead to fatal outcomes. Interestingly, the optimal timing, indications, and surgical techniques have not been standardized. METHOD: We retrospectively analyzed 35 patients who underwent surgical treatment for chest trauma. RESULTS: All patients with penetrating trauma (n=4) underwent emergency surgery for a hemothorax...

BACKGROUND: Currently, conventional closed thoracic drainage for pneumothorax involves a painful procedure with a higher risk and wider (1~1.5 cm) incision. Minimally invasive catheterized drainage techniques are urgently needed to address this challenge. OBJECTIVE: This retrospective study aims to observe the effects of conventional closed thoracic drainage with deep venous catheterization drainage techniques on pneumothorax patients. DESIGN: It was a retrospective study...

BACKGROUND: Next-day discharge (NDD) outcomes following uncomplicated self-expanding transcatheter aortic valve replacement have not been studied. Here, we compare readmission rates and clinical outcomes in NDD versus non-NDD transcatheter aortic valve replacement with Evolut. METHODS AND RESULTS: Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry patients (n=29 597) undergoing elective transcatheter aortic valve replacement with self-expanding supra-annular valves (Evolut R, PRO, and PRO+) from July 2019 to June 2021 were stratified by postprocedure length of stay: ≤1 day (NDD) versus >1 day (non-NDD)...

STUDY DESIGN: A retrospective comparative study was conducted to analyze the outcome of surgical and conservative treatment for patients over 80 years old with thoracic spinal stenosis (TSS). OBJECTIVE: To evaluate the safety and efficiency of posterior spinal cord decompression surgery for over 80-year-old patients with TSS. SUMMARY OF BACKGROUND DATA: Concerned about the risk of surgery, over 80-year-old patients with TSS are usually treated conservatively, which often leads to a decline in quality of life...

OBJECTIVE: This study aimed to compare two commercially available off the shelf branched endografts for thoraco-abdominal aortic aneurysm (TAAA) repair, namely the E-nside (Artivion) and Zenith t-Branch (Cook Medical) devices. METHODS: This multicentre retrospective study (2020 - 2023) included patients treated by branched endovascular aortic repair (BEVAR) for TAAA using the inner branched E-nside or the outer branched t-Branch.

The presented case report demonstrates the successful operative treatment of a patient with thymic carcinoma located in the anterior mediastinum, infiltrating the vena cava, and affecting the upper lobe of the left lung. Our multidisciplinary approach, incorporating various operative techniques, proved effective in treating this type of pathology. The Clinic for Thoracic Surgery at UMHAT Kaspela, Plovdiv admitted a 72-year-old female patient due to complaints related to her cardiovascular and respiratory systems...

A 37-year-old lady with infective endocarditis of the mitral valve presented in congestive cardiac failure. However, the clinical scenario became complicated when she was also found to have antiphospholipid antibody syndrome. Meticulous optimization and timely surgical intervention by a multidisciplinary team helped mitigate this not so common situation and lead to successful outcome.

OBJECTIVES: Aortic pathologies often present with elevated inflammatory biomarkers due to the nature of the disease. Open aortic surgery causes significant trauma to the body due to often mandatory ischemic periods, long cardiopulmonary bypass times and polytransfusion. We aim to determine postoperative trends on inflammation biomarkers for different aortic pathologies and type of surgery in different segments of the aorta. METHODS: Retrospective review of prospectively collected data of 193 consecutive patients who underwent aortic surgery in our centre between 2017 and 2021, grouped according to the type of aortic intervention: (1) Type A aortic dissection (AD) repair with ascending aorta/hemiarch replacement, (2) Aortic root replacement (ARR), (3) Aortic arch + Frozen elephant trunk (FET), (4) Descending thoracic aorta (DTA)/Thoraco-Abdominal aortic repair (TAA)...

OBJECTIVES: The study was designed to evaluate the superiority of the subxiphoid approach comparing with the lateral intercostal approach during the process of operation, and other perioperative indices. METHODS: Patients diagnosed anterior mediastinal disease in our hospital between January 2018 and October 2019 were prospectively assigned into two groups, receiving the lateral intercostal approach or the subxiphoid approach VATS to resect the disease. The PaCO2, SaO2, PaO2 and circulation changes were recorded during the operation, neutrophil-to-lymphocyte ratio, and other perioperative outcomes, including clinical and surgical results, operation time, blood loss, postoperative complication, postoperative pain score were compared...

Intrathoracic needles are rarely used in clinical practice. They can migrate within the body, injure large blood vessels and other organs, and cause severe complications. We report an interesting case of intrathoracic needle removal using video-assisted thoracoscopic surgery. The needle was inserted under the left clavicle, penetrated the mediastinum, and migrated into the right thoracic cavity. Although pneumothorax developed during the disease course, no severe complications were observed. This rare case illustrates the course of needle migration from the mediastinum into the thoracic cavity...

BACKGROUND: Current management of axillosubclavian deep venous thrombosis (DVT) often uses thrombolysis for the DVT, prompt first rib removal, and occasional venoplasty or stenting. Our institution has increasingly used anticoagulation alone followed by interval first rib resection. We sought to analyze the effectiveness of this simplified technique. METHODS: Between September 2012 and April 2021, 27 patients were identified within the institution's electronic medical record as having undergone first rib resection for upper extremity DVT...

The acute aortic syndromes (AAS) are life-threatening vascular compromises within the aortic wall. These include aortic dissection (AD), intramural hematoma (IMH), penetrating aortic ulcer (PAU), and blunt traumatic thoracic aortic injury (BTTAI). While patients classically present with chest pain, the presentation may be highly variable. Timely diagnosis is critical to initiate definitive treatment and maximize chances of survival. In high-risk patients, treatment should begin immediately, even while diagnostic evaluation proceeds...
