Introduction

Thoracic surgery, a specialized branch of surgery focusing on the chest region, has witnessed remarkable advancements in recent years. These advancements have revolutionized the field, leading to the development of innovative techniques and technologies aimed at improving respiratory health outcomes. With the increasing prevalence of respiratory conditions such as lung cancer, thoracic surgery plays a critical role in the diagnosis, treatment, and management of these diseases [1]. This introduction provides an overview of the advancements in thoracic surgery, highlighting the innovations and techniques that have emerged to enhance respiratory health. One of the key breakthroughs in thoracic surgery is the advent of minimally invasive techniques. Traditional open surgeries, involving large incisions and extensive tissue manipulation, are being replaced by minimally invasive approaches like video-assisted thoracic surgery (VATS) and robotic-assisted surgery. These techniques utilize smaller incisions and specialized instruments, allowing for reduced trauma, decreased postoperative pain, and faster recovery times for patients. The use of VATS and robotic-assisted surgery has expanded across various thoracic procedures, including lung resections, esophageal surgeries, and thymectomy, among others. In parallel with minimally invasive techniques, advancements in imaging and navigation have significantly contributed to improved outcomes in thoracic surgery. High-resolution imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) provide detailed anatomical information, aiding surgeons in preoperative planning and intraoperative guidance. These imaging techniques allow for precise localization and assessment of lung nodules, tumors, and other abnormalities, facilitating targeted interventions with reduced damage to healthy tissues. Furthermore, image-guided procedures have emerged as powerful tools in the field of thoracic surgery [2-4]. Techniques like electromagnetic navigation bronchoscopy (ENB) and transthoracic needle biopsy utilize real-time imaging to guide instruments and needles to previously challenging-to- reach areas of the lung. These procedures enable less invasive diagnostics and therapeutics, leading to improved patient outcomes and reduced risks. Lung-sparing resections have also gained prominence as an innovative approach in thoracic surgery. Traditionally, lobectomy, the removal of an entire lobe of the lung, has been the standard treatment for lung cancer. However, advancements in surgical techniques and imaging have made it possible to perform more conservative procedures, such as segmentectomy and wedge resections, which preserve a greater amount of healthy lung tissue while still ensuring adequate removal of the tumor. These lung-sparing techniques have demonstrated favorable outcomes in selected cases, particularly for early-stage lung cancer patients with compromised lung function. In addition to these advancements, robotic-assisted thoracic surgery (RATS) has emerged as a valuable tool in complex thoracic procedures. With improved dexterity, precision, and visualization, robotic systems enable surgeons to perform intricate maneuvers with enhanced control. RATS has been successfully applied in lung resections, thymectomy, and other challenging thoracic surgeries, further expanding the capabilities of minimally invasive approaches [5-8]. Transplantation innovations have also played a significant role in improving respiratory health. Lung transplantation remains a vital treatment option for patients with endstage lung diseases. Advances in donor organ preservation, recipient selection, and surgical techniques have led to improved outcomes and expanded the donor pool. Ex vivo lung perfusion (EVLP), a technique that allows assessment and reconditioning of donor lungs outside the body, has contributed to the utilization of previously marginal organs, thereby increasing the availability of suitable lungs for transplantation. These advancements in thoracic surgery are complemented by the implementation of Enhanced Recovery After Surgery (ERAS) protocols. These multidisciplinary approaches focus on optimizing perioperative care, including preoperative preparation, minimally invasive techniques, multimodal pain management, and early mobilization. By incorporating evidence-based practices, ERAS protocols have shown promising results in reducing complications, shortening hospital stays, and promoting faster recovery following thoracic surgery[9,10].
