TürkçeThoracic surgery is the medical specialty that focuses on the diagnosis and surgical treatment of diseases affecting the lungs, pleura, mediastinum, diaphragm, and chest wall. This specialty encompasses a broad spectrum of conditions ranging from traumatic injuries to tumors and utilizes advanced surgical techniques.
Diseases managed by thoracic surgery include lung cancer, pleural tumors, mediastinal masses, and chest wall deformities. In addition, emergency conditions such as pneumothorax, hemothorax, and empyema are also evaluated and treated by this specialty.
Surgical diseases originating from the lungs and pleura may lead to serious clinical conditions that directly affect respiratory function. Especially in malignant lung tumors, early diagnosis and appropriate surgical resection increase survival rates. In pleural diseases, fluid accumulation and infections are managed with surgical techniques.
Minimally invasive thoracic surgery procedures include video-assisted thoracoscopic surgery and robotic techniques. These methods allow operations through smaller incisions, shorten hospital stays, and reduce complication rates. A multidisciplinary approach is essential in advanced-stage cases.
Which Organs and Regions Does Thoracic Surgery Cover?
The thoracic cavity is a closed and protected anatomical compartment extending from the base of the neck to the powerful diaphragm muscle that separates it from the abdominal cavity.
The primary function of this cavity is to protect the major organs of the respiratory system and the center of the circulatory system from external influences. While the heart and the major blood vessels arising from it belong to the field of cardiovascular surgery, all the remaining tissues and organs within this vital cavity fall under the responsibility of thoracic surgery.
The lungs, located on the right and left sides, are sponge-like organs responsible for filtering air and delivering oxygen to the bloodstream, occupying the central part of this region. Covering these lungs like an envelope are the double-layered membranes known as the pleura, which prevent friction during breathing. The trachea, which carries inhaled air into the depths of the lungs, and the esophagus, which transports food from the mouth to the stomach while passing through the thoracic cavity, are also integral components of this complex system.
Surrounding all these organs externally are the flexible yet durable rib cage, the sternum (breastbone), and the intercostal muscles, which together form the chest wall. Located in the center of the thoracic cavity is the mediastinum surrounding the heart, a critical region where various cysts and tumors may develop. All these structures function continuously together like an extraordinarily well-coordinated machine.
The principal structures included in this specialty are:
- Lungs
- Trachea
- Esophagus
- Pleural membranes
- Diaphragm muscle
- Chest wall bones
What Surgical Approach Does Thoracic Surgery Take in Lung Cancer?
Lung cancer constitutes the largest, most detailed, and most critical area of thoracic surgical practice. Numerous factors, including the stage of the cancer, the patient’s age, overall health, cardiac function, and the capacity of the remaining healthy lung tissue, determine the type of operation. The primary objective of surgery is to completely remove the cancerous tissue while preserving sufficient lung capacity for comfortable breathing after the procedure.
Anatomically, the lungs are not single structures. The right lung consists of three lobes, while the left consists of two. In early-stage lung cancer, the internationally accepted standard surgical procedure is lobectomy. During this operation, the lobe containing the tumor is completely removed together with its associated blood vessels and airways. This approach is preferred because cancer has the potential to spread not only to the visible tumor but also through microscopic pathways within the affected lobe.
If the detected tumor is very small, has not yet spread to the lymph nodes, or if the patient’s respiratory reserve is insufficient to tolerate removal of an entire lobe, smaller resections may be preferred. Wedge resection, in which the tumor and a margin of healthy tissue are removed, or segmentectomy, in which a smaller anatomical segment of the lung is excised, may be life-saving in these circumstances. In rare cases where the tumor is located very close to the central structures of the lung, removal of the entire lung on that side may become necessary.
The main surgical procedures include:
- Lobectomy
- Segmentectomy
- Wedge resection
- Pneumonectomy
Which Chest Wall Deformities Are Treated by Thoracic Surgery?
Chest wall deformities are structural abnormalities that are usually congenital or become prominent during childhood growth due to abnormal development of the ribs and sternum. Although often regarded as cosmetic concerns, these conditions may reduce the volume of the thoracic cavity and restrict the function of internal organs.
The most well-known deformity is a sunken chest, where the chest wall collapses inward like a bowl. This depression may mechanically compress the heart and lungs, causing children to tire easily during physical activity, experience shortness of breath, or develop palpitations. Another common deformity is an outward protrusion of the chest wall. Both conditions may result in significant psychological distress, poor posture, and social withdrawal, particularly during adolescence.
Today, large open procedures have largely been replaced by minimally invasive techniques. Through tiny incisions made on both sides of the chest, specially bent steel or titanium bars are placed behind the sternum. These bars either elevate the depressed sternum or apply pressure to correct an outward protrusion. After remaining in place for several years, they permanently reshape the chest wall into a normal anatomical position.
The principal deformities treated include:
- Pectus excavatum
- Pectus carinatum
- Poland syndrome
Which Treatments Does Thoracic Surgery Perform for Pleural Diseases?
The lungs do not lie directly within the chest cavity. Instead, they are enclosed by a thin double-layered membrane known as the pleura. Under normal circumstances, a small amount of lubricating fluid exists between these layers, allowing the lungs to move smoothly during breathing. Trauma, infection, or systemic diseases may disrupt this balance and cause significant respiratory problems.
One of the most common emergencies is pneumothorax, commonly known as a collapsed lung. This occurs when a congenital weak air sac on the lung surface ruptures during coughing, sneezing, or heavy lifting, allowing air to leak into the pleural cavity. The trapped air compresses the lung from outside, causing it to collapse. Another common condition is abnormal fluid accumulation between the pleural layers. Pneumonia, heart failure, or malignant diseases may lead to liters of fluid collecting around the lungs, compressing them and causing severe shortness of breath.
In these situations, a thin tube is inserted into the pleural cavity under local anesthesia to drain the accumulated air or fluid. If the problem recurs or persists, minimally invasive surgery is performed to repair ruptured blebs or remove infected pleural tissue.
The main pleural diseases include:
- Pneumothorax
- Pleural effusion
- Empyema
- Mesothelioma
Does Thoracic Surgery Provide a Permanent Solution for Excessive Sweating?
Excessive sweating is characterized by uncontrollable perspiration of the hands, underarms, or face, regardless of stress, excitement, or environmental temperature. Besides physical discomfort, it often causes significant psychological distress by making individuals reluctant to shake hands, handle paper, or participate comfortably in social situations. Although creams, medications, and injections may provide temporary relief, they rarely offer permanent results.
The sympathetic nervous system controls sweat gland activity. Interestingly, the sympathetic nerve chain responsible for sweating of the hands and underarms runs along both sides of the spine within the chest cavity. In hyperhidrosis, these nerves continuously send excessive signals.
The most definitive treatment is a minimally invasive operation performed through a tiny incision beneath the armpit. Using a camera, the surgeon identifies the sympathetic nerve chain and either divides or clips the specific branches responsible for excessive sweating. The procedure is brief, and patients typically notice that their hands become warm and dry immediately after waking from surgery. This operation provides a dramatic improvement in quality of life.
Are Esophageal Diseases Included in Thoracic Surgery?
The esophagus is a muscular and flexible tube that transports food from the mouth to the stomach. It extends from the neck through the chest, passes behind the heart, traverses the diaphragm, and joins the stomach in the abdomen. Because most of its anatomical course lies within the thoracic cavity, surgical treatment of esophageal diseases is among the most challenging areas of thoracic surgery.
Esophageal cancers require extremely delicate surgery due to their proximity to the trachea, aorta, and heart. After removing the cancerous esophagus, a narrow tube is usually created from the stomach and brought into the chest, where it is connected to the remaining healthy portion of the esophagus in the neck. In addition to cancer, esophageal diverticula and perforations resulting from penetrating injuries also require surgical treatment.
The principal conditions treated include:
- Esophageal cancer
- Esophageal perforation
- Esophageal diverticulum
- Esophageal stricture
How Does Thoracic Surgery Manage Trauma and Injuries?
Traffic accidents, falls, workplace injuries, blunt chest trauma, and firearm injuries are all classified as thoracic trauma. Because the chest protects the body’s most vital organs, disruption of this protective structure may rapidly become life-threatening.
Rib fractures are particularly common following motor vehicle accidents. Although they may appear to be simple bone injuries, fractured ribs can puncture the pleura, collapse the lung, or cause significant bleeding into the chest cavity. Multiple fractures may destabilize the chest wall, resulting in paradoxical movement during breathing.
The initial life-saving intervention usually involves inserting a chest tube under local anesthesia to rapidly evacuate air or blood from the pleural cavity, allowing the lung to re-expand. Severe cases involving ongoing bleeding, airway disruption, or unstable rib fractures require emergency open surgery to control bleeding and stabilize the chest wall using titanium plates and screws.
Which Operations Does Thoracic Surgery Perform for Tracheal Diseases?
The trachea is the body’s only airway for delivering air to the lungs. It is supported by flexible cartilage rings that maintain its structure. Patients requiring prolonged mechanical ventilation may develop narrowing of the trachea due to pressure from the endotracheal tube, which compromises blood supply and eventually leads to scar formation.
These strictures cause wheezing and severe shortness of breath, even during minimal physical activity. Surgical treatment involves removing the narrowed or diseased segment of the trachea and reconnecting the healthy ends using meticulous suturing techniques. Careful postoperative management is essential to prevent excessive tension on the repair during neck movement.
Why Is Respiratory Capacity Measured Before Thoracic Surgery?
Making the decision to perform thoracic surgery involves much more than identifying diseased tissue on imaging. Successful surgery depends on whether the patient can tolerate the operation and breathe independently afterward. When part or all of a lung is removed, surgeons must accurately predict whether the remaining lung tissue will meet the body’s oxygen requirements.
Pulmonary function testing provides this information. Patients are asked to inhale deeply and then exhale forcefully into a computerized device. These tests measure lung volume, detect hidden airway obstruction, and assess cough strength. If results are borderline, more advanced exercise testing is performed to evaluate how efficiently the body utilizes oxygen. The goal is to ensure safe surgery while minimizing the risk of postoperative respiratory failure.
The principal tests used before surgery include:
- Spirometry
- Diffusion capacity test
- Cardiopulmonary exercise test
- Six-minute walk test
- Stair climbing test
How Are Patients Prepared Before Thoracic Surgery?
Patients with borderline respiratory function or increased surgical risk are not immediately excluded from surgery. Instead, they undergo a period of preoperative rehabilitation designed to improve their physical condition before the operation.
The most important requirement is complete smoking cessation at least one month before surgery. Stopping smoking reduces airway inflammation, decreases mucus production, and significantly lowers the risk of postoperative pneumonia. Patients with chronic bronchitis or asthma receive medications to maximize airway function. Nutritional deficiencies are corrected, anemia is treated, and patients with sleep apnea may begin positive airway pressure therapy before surgery to reduce postoperative complications.
The primary goals during preparation include:
- Smoking cessation
- Breathing exercises
- Nutritional support
- Medication adjustment
- Weight management
What Are Minimally Invasive Thoracic Surgery Techniques and Their Advantages?
In the past, thoracotomy required long incisions extending between the ribs. Surgeons often had to spread the ribs widely or even remove part of a rib to gain adequate exposure. Although this approach provided excellent visualization, it resulted in considerable pain and prolonged recovery.
Advances in cameras and microsurgical instruments have transformed thoracic surgery. Today, many procedures, including lung cancer operations, are performed using video-assisted thoracoscopic surgery (VATS). Through one or several small incisions, high-definition cameras and slender instruments are introduced into the chest. The surgeon performs the operation while viewing magnified images on monitors. Robotic surgery represents an even more advanced approach, allowing the surgeon to control articulated robotic arms from a console using three-dimensional visualization.
The greatest advantage of minimally invasive surgery is preservation of the chest wall muscles and ribs. Patients experience significantly less pain, breathe and cough more comfortably, leave the hospital sooner, and return more quickly to normal activities or additional cancer treatments if necessary.
The most commonly performed surgical approaches include:
- Open surgery
- Video-assisted thoracoscopic surgery
- Robotic surgery
What Should Be Considered During Recovery After Thoracic Surgery?
A successful operation represents only the first half of recovery. Full rehabilitation depends on careful postoperative management in both the intensive care unit and the surgical ward. Regardless of whether minimally invasive techniques are used, patients naturally tend to breathe shallowly because of pain.
Shallow breathing may cause collapse of the lower lung segments, retention of secretions, and eventually pneumonia. Postoperative care therefore focuses on pain control, lung expansion, and early mobilization. Adequate pain relief enables patients to breathe deeply without fear.
Patients are provided with incentive spirometers that encourage repeated deep breathing exercises every hour. These exercises reopen collapsed air sacs within the lungs. Early walking, often beginning the day after surgery or even on the same day, stimulates circulation, improves bowel function, and reduces the risk of blood clots. Patients are encouraged to support their chest with a pillow while coughing forcefully to clear secretions. Successful recovery depends on teamwork among the surgeon, nursing staff, and patient.
The key elements of postoperative care include:
- Pain medication
- Early mobilization
- Deep breathing
- Forceful coughing
- Incentive spirometry exercises
