{"title":"[Intraoperative Transesophageal Echocardiography].","authors":"Kazumasa Orihashi","doi":"","DOIUrl":"","url":null,"abstract":"Transesophageal echocardiography (TEE) is a valuable diagnostic and intraoperative tool that allows high-resolution, real-time imaging of deep cardiovascular structures without interfering with surgery. It offers dynamic information similar to computed tomography (CT) or magnetic resonance imaging (MRI) but without radiation exposure, making repeated assessments feasible. During cardiovascular surgery, TEE guides cannula placement, monitors myocardial protection, detects complications like air embolism and intraoperative aortic dissection, and facilitates real-time surgical navigation. Its utility extends to postoperative intensive care unit (ICU) care and emergency settings, where it helps diagnose complications when CT is not feasible. In thoracic surgery, TEE aids in assessing tumor invasion into cardiovascular structures. However, TEE's effectiveness heavily relies on the operator's skill, unlike the objectivity of radiologic modalities. Thus, fostering collaboration between anesthesiologists and surgeons is essential. As a critical part of perioperative management, TEE proficiency is now a requirement for board certification in cardiovascular anesthesia in Japan. Supporting anesthesiologists in developing TEE skills enhances surgical outcomes and institutional capability.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

{"title":"[Latest Innovations in Illumination and Engineering Equipment for Thoracic Surgery].","authors":"Daisuke Takeyoshi, Hiroyuki Kamiya","doi":"","DOIUrl":"","url":null,"abstract":"In thoracic surgery, where precision and safety are paramount, advanced lighting and optical technologies play a critical role in enhancing surgical outcomes. Recent developments in lighting systems have improved brightness, reduced heat generation, and enabled more accurate color rendering, supporting safer and more efficient procedures. The shift toward minimally invasive techniques, such as thoracoscopic and robot-assisted surgeries, has further accelerated the need for high-quality visualization tools. Three-dimensional (3D) imaging, high-resolution displays, and fluorescence-guided visualization now allow for better identification of anatomical structures. Furthermore, augmented reality (AR) and artificial intelligence (AI) are being integrated into surgical practice. Preoperative imaging data can be reconstructed in 3D and overlaid during surgery to enhance accuracy in tumor localization and vascular mapping. Wearable optical devices and digital operating room systems are also improving communication and collaboration among surgical teams, allowing for real-time sharing of visual information and remote guidance. These technologies are increasingly contributing not only to surgical precision but also to team-based workflows, education, and training. Looking ahead, real-time AI-AR fusion systems and remote navigation support may further transform thoracic surgery by enabling safer, more informed decision-making in complex procedures.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

{"title":"[Photodynamic Therapy for Peripheral Lung Cancer].","authors":"Jitsuo Usuda","doi":"","DOIUrl":"","url":null,"abstract":"Photodynamic therapy (PDT) utilizes a tumor-specific photosensitizer with low-power laser irradiation and this treatment has been established for centrally located lung cancers. However, its application to peripheral type lung cancers remains investigational. Recently, there has been interest in minimally invasive ablative therapies are needed for peripheral type lung cancer and several bronchoscopic ablative modalities are currently under investigation. In this study, a novel laser probe was developed and a multicenter randomized clinical trial was conducted to assess the safety and efficacy of PDT for peripheral lung cancer, and to establish a novel bronchoscopic treatment. Patients with non-small cell lung cancer diagnosed by transbronchial lung biopsy with a tumor diameter of 25 mm or less and ineligible for surgery or radiotherapy were enrolled. A randomized controlled trial was conducted with a 2:1 ratio between the PDT group and the best supportive care (BSC) group. The primary endpoint was progression-free survival (PFS), and the secondary endpoint was overall survival (OS). For the BSC group, salvage PDT (sPDT) was permitted for patients with a PD diagnosis and a tumor diameter of 30 mm or less. Patients were enrolled from May 2020 to May 2023 at six hospitals, with a total of 54 cases included, including 35 cases in the PDT group and 19 cases in the BSC group. Among the cases in the BSC group, sPDT was performed in 14 cases. The median PFS was 12.7 months [95% confidence interval (CI): 6.7, 30.0] in the PDT group, and the median PFS was 4.1 months (95% CI: 2.9, 7.4) in the BSC group. Kaplan-Meier survival analysis (log-rank test, p=0.0172) demonstrated a significant prolongation of the PFS in the PDT group. The incidence of serious adverse events was 5.9% (two patients) in the PDT group and 0% in the sPDT group. The findings of this study indicate that PDT for peripheral lung cancer led to a significantly prolongation of PFS and was safe to perform. PDT demonstrated efficacy in preserving lung function, inhibiting lung cancer progression, and maintaining a good quality of life.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

{"title":"[Mediastinoscopic and Transabdominal Robotic Esophagectomy Using da Vinci Xi].","authors":"Takashi Mitsui, Yuhei Hakozaki","doi":"","DOIUrl":"","url":null,"abstract":"Mediastinoscopic esophagectomy (ME) for esophageal cancer, first reported by Tangoku et al. in 2004, has evolved into a standardized procedure incorporating radical lymphadenectomy. The surgery is performed using a mediastinoscope from the neck and a laparoscope from the abdomen, creating a connected operative field within the mediastinum. ME avoids thoracotomy and one-lung ventilation, preserving respiratory muscles and significantly reducing postoperative pneumonia, while maintaining pulmonary function and quality of life. Meta-analyses have shown that although recurrent laryngeal nerve palsy is relatively common, ME results in shorter operative time, less blood loss, lower incidence of pneumonia, and a reduced overall complication rate compared to conventional approaches. Its greatest advantage lies in expanding surgical indications to patients who were previously considered inoperable due to thoracic adhesions, poor pulmonary function (e.g., chronic obstructive pulmonary disease (COPD)), or prior thoracic surgery. These patients often cannot tolerate radiation either, making ME particularly valuable. As Japan's population continues to age, the need for ME is expected to grow. Although ME was covered by national insurance in 2018, evidence from Japan remains limited. The 2022 esophageal cancer guidelines refrain from recommending ME due to insufficient data. However, recent retrospective studies using propensity score matching have shown significantly better overall and disease-free survival compared to thoracotomy, and prospective multicenter trials are underway.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.
