Surgical outcomes and learning curve of complex versus simple segmentectomy for uniportal video-assisted thoracoscopic surgery: an initial experience of 100 cases of a single experienced surgeon.

Background: Complex segmentectomy for uniportal video-assisted thoracoscopic surgery (VATS) remains controversial due to procedural complexity and the risk of increased complications, unlike multiportal VATS. Demonstrating the perioperative results and proficiency of individual surgeon is believed to influence future dissemination for uniportal VATS. In this study, we aimed to compare the perioperative outcomes and learning curves of complex versus simple segmentectomy for uniportal VATS.

Successful surgical intervention for acute pyothorax caused by methicillin-resistant Staphylococcus aureus thoracic pyogenic spondylitis: a case report.

Background: Pyogenic spondylitis or intervertebral discitis rarely spreads into the thoracic cavity, resulting in pyothorax. Moreover, no study has reported methicillin-resistant Staphylococcus aureus (MRSA) as a cause. Conservative and surgical treatments are reportedly effective for the above-mentioned situations; however, there have been no comprehensive reports owing to the disease's rarity.

Lymphoid follicular hyperplasia arising from the chest wall presenting as a substantial mass.

Lymphoid follicular hyperplasia (LFH) is a benign lymphoproliferative disease. Although it can occur within the thoracic cavity, LFH originating from the chest wall has not been reported. A 79-year-old woman was incidentally found to have a well-defined mass on the left posterior chest wall during a preoperative examination for aortic valve replacement.

Predictive factors of early autologous blood pleurodesis for postoperative air leak.

Background: The usefulness of autologous blood pleurodesis for air leak after pulmonary resection is well known; however, factors predicting the therapeutic efficacy are poorly understood. Herein, we aimed to examine the predictors of early autologous blood pleurodesis for air leak following pulmonary resection.

Methods: Patients who underwent pulmonary resection and autologous blood pleurodesis with thrombin for postoperative air leak between January 2016 and October 2022 were retrospectively analyzed.

Prediction of visceral pleural invasion of clinical stage I lung adenocarcinoma using thoracoscopic images and deep learning.

Purpose: To develop deep learning models using thoracoscopic images to identify visceral pleural invasion (VPI) in patients with clinical stage I lung adenocarcinoma, and to verify if these models can be applied clinically.

Methods: Two deep learning models, one based on a convolutional neural network (CNN) and the other based on a vision transformer (ViT), were applied and trained via 463 images (VPI negative: 269 images, VPI positive: 194 images) captured from surgical videos of 81 patients. Model performances were validated via an independent test dataset containing 46 images (VPI negative: 28 images, VPI positive: 18 images) from 46 test patients.

Effectiveness and failure factors of manual aspiration using a small needle for large pneumothorax in stable patients.

Background: Manual aspiration as the initial management of a large pneumothorax in a clinically stable patient has been reported to be safe and effective. However, the effect with smaller needles, the number of aspiration, the indication other than spontaneous pneumothorax and failure factors are unknown. We assessed the effectiveness and failure risk factors of manual aspiration up to three using a 20- or 22-gauge (G) needle in patients with a large, clinically stable pneumothorax.

Adverse factors and postoperative neuropathic pain in challenging video-assisted thoracoscopic surgery.

Background: Whether challenging video-assisted thoracoscopic surgery (VATS) is a minimal invasive surgery remains controversial. This study aimed to analyze causes of challenging conventional multiple-port VATS (CVATS) and conversion to thoracotomy and postoperative pain to provide indications for VATS.

Methods: This was a two-center retrospective study.

Utility of the sliding lung sign for the prediction of preoperative intrathoracic adhesions.

Background: To assess the potential of the ultrasonographic sliding lung sign to detect severe intrathoracic adhesions before surgery.

Methods: This was a prospective, single-center, observational study including all patients aged 20-89 years undergoing elective thoracic surgery. Patients with pneumothorax, pyothorax, hemothorax, chylothorax, and hydrothorax were excluded.

Use of Quickfix for tape fixation of chest tubes: a multi-center doctor-nurse questionnaire survey and fixing strength comparison study.

Background: Several tape fixations for chest tube were proposed, although none have a clear scientific basis. We performed a multicenter survey study to investigate the fixation of chest tubes using an available adhesive tape. We evaluated the strength of tape fixation and the effect of the skin coating material used on the fixation strength.

Peripheral pulmonary hamartoma with haemoptysis from the non-adjacent bronchus.

We report a rare case of peripheral pulmonary hamartoma that caused haemoptysis from the non-adjacent bronchus. A 54-year-old man was admitted to our hospital because of haemoptysis. Contrast-enhanced chest computed tomography revealed a tumour measuring 25 × 24 mm in the left lower lobe.

Treatment of airway stenosis with a customized bronchial stent using a three-dimensional printer and flexible filaments.

Stent placement is recommended for patients with airway stenosis. However, ready-made stents may be difficult to fit over lesioned areas. In the current case report, we describe the creation and placement of a custom stent in an 84-year-old woman with airway stenosis.

A case of a pulmonary mucosa-associated lymphoid tissue lymphoma with chromosomal aberration (49, XX, +3, +i(6)(p10), +mar).

We report a case of a primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma with chromosomal aberration (49, XX, +3, +i(6)(p10), +mar). A 59-year-old woman was referred to our hospital for an abnormal chest shadow detected during a routine health check-up in 2014. Chest computed tomography revealed a 3.

Efficacy of 50 mg pregabalin for prevention of postoperative neuropathic pain after video-assisted thoracoscopic surgery and thoracotomy: a 3-month prospective randomized controlled trial.

Background: This study analyzed the preventive effect of 50 mg/day pregabalin on postoperative neuropathic pain, and any additional benefits related to sleep and respiratory function.

Methods: This prospective randomized controlled study included lung resection patients 20-89 years of age. Patients were randomly assigned to the treatment (pregabalin; initial dose, 50 mg/day) or control (non-steroidal anti-inflammatory drugs) group.

Risk factors of neuropathic pain after thoracic surgery.

Background: This study aimed to clarify the incidence and risk factors of neuropathic pain after thoracic surgery, focusing especially on patients who underwent complete video-assisted thoracoscopic surgery (VATS).

Methods: We retrospectively identified 185 patients who underwent thoracic surgery at our hospital over a 2-year period. Logistic regression analysis was used to analyze the association of various factors with postoperative neuropathic pain.

Spontaneous Hemothorax Caused by Pulmonary Micro-Venous Hemangioma.

Various etiologies of spontaneous hemothorax have been reported, though the cause remains unidentified in some patients despite an exploratory thoracotomy. We report on an 89-year-old man with spontaneous hemothorax resolved by partial resection of the lung using complete video-assisted thoracoscopic surgery. The histopathologic findings revealed a ruptured micro-venous hemangioma located just below the bleeding visceral pleura.

Rare lipomatous tumor of the posterior mediastinum in children.

The mediastinum is a unique anatomic area containing various structures and pluripotent cells, which allow for the development of a range of tumors. We report two pediatric cases of a lipomatous tumor of the posterior mediastinum. Complete surgical excision of the mass in each was achieved through a lateral thoracotomy.

Complete thoracoscopic diaphragm plication using carbon dioxide insufflation: report of a case.

Diaphragm plication has become the accepted treatment for major respiratory impairment caused by diaphragmatic eventration and paralysis. Various open and minimally invasive plication techniques have been described and while video-assisted thoracoscopic diaphragm plication appears to be a safe and effective alternative to open surgery, the workspace is limited. We describe how we performed complete thoracoscopic diaphragm plication using carbon dioxide (CO2) insufflation for a patient with unilateral diaphragmatic eventration.
