Thoracoscopy

Thoracoscopy

There are many health conditions in medical practice where imaging alone doesn't give us the complete answer. A CT scan may reveal fluid around the lung, or thickening of the pleural lining, or a shadow that doesn't quite fit a straightforward diagnosis. The patient has been treated empirically, the X-rays have been repeated, and yet the question remains: What exactly is causing this? Thoracoscopy is often how we find out. It is a procedure we recommend at our Department of Pulmonology for a purpose, not routinely. When it is indicated, it changes the clinical trajectory almost every time.

Thoracoscopy, also called pleuroscopy in certain contexts, is a minimally invasive procedure that allows direct visualization of the pleural cavity, the space between the two layers of membrane that surround the lung. Through a small incision, typically 1 to 2 centimetres, made in the lateral chest wall, usually between the fourth and seventh intercostal spaces, a thin, rigid or semi-rigid telescope is introduced. This transmits real-time images to a monitor, allowing the treating physician to examine the visceral and parietal pleural surfaces, identify abnormalities, take targeted biopsies, and perform certain therapeutic procedures.

It is important to distinguish between two forms of this procedure that patients often confuse:

  • Medical Thoracoscopy (Pleuroscopy)
    performed by a pulmonologist, usually under conscious sedation with local anaesthesia, in a bronchoscopy suite or procedure room; primarily diagnostic, with some therapeutic applications such as fluid drainage and pleurodesis; the patient is awake but comfortable, and recovery is relatively quick
  • Video-Assisted Thoracoscopic Surgery (VATS)
    performed by a thoracic surgeon in an operating theatre under general anaesthesia; more complex, capable of lung resections, lymph node dissection, and surgical interventions; the scope and capability are significantly broader

Conditions for which thoracoscopy is commonly indicated include:

  • Undiagnosed pleural effusion
    especially exudative effusions where cytology and pleural fluid biochemistry have been inconclusive
  • Suspected pleural tuberculosis
    TB remains one of the leading causes of pleural effusion in our patient population; thoracoscopy allows targeted biopsy of pleural granulomas with a diagnostic yield significantly higher than blind biopsy
  • Suspected mesothelioma
    a malignancy of the pleural lining, often linked to asbestos exposure; diagnosis requires adequate tissue, which thoracoscopy reliably provides
  • Malignant pleural effusion
    secondary to lung, breast, or other cancers; thoracoscopy confirms the diagnosis and allows pleurodesis in the same sitting
  • Pleural empyema and complicated parapneumonic effusion
    where adhesions and loculations need to be broken down to allow drainage
  • Unexplained pneumothorax
    to identify blebs or bullae and assess the pleural surface
  • Staging of lung cancer
    assessing pleural involvement before treatment decisions are made

Patients are understandably apprehensive when thoracoscopy is first mentioned. In practice, medical thoracoscopy is far less daunting than most patients expect.

The procedure typically unfolds as follows:

  • Positioning
    you will lie on your side, with the affected side facing upward; monitoring lines for oxygen saturation, heart rate, and blood pressure are placed
  • Anaesthesia
    local anaesthetic is infiltrated into the skin and intercostal muscles at the entry site; intravenous sedation is administered to keep you comfortable and relaxed; you remain breathing on your own throughout
  • Port insertion
    a small incision is made, and a trocar (a narrow access port) is placed through the chest wall into the pleural space
  • Visualisation
    the thoracoscope is introduced; the pleural surfaces are examined methodically; any fluid present is simultaneously drained
  • Biopsy
    if abnormal areas are identified, targeted biopsies are taken using forceps passed through the same port; multiple samples are collected to maximise diagnostic yield
  • Pleurodesis
  • a talc slurry or other sclerosing agent may be instilled into the pleural cavity to cause the two pleural layers to adhere, preventing fluid from re-accumulating
  • Chest tube placement
    a small intercostal drain is left in position at the end of the procedure to drain residual air or fluid; this is usually removed within 24 to 48 hours

The procedure itself takes approximately 30 to 60 minutes in most cases.

Recovery from medical thoracoscopy is generally faster than patients anticipate. Most individuals are observed in the ward for 24 to 48 hours following the procedure, primarily to monitor the chest drain and confirm adequate lung re-expansion on a post-procedure X-ray.

After discharge, strenuous activity should be avoided for approximately one week. The small incision site heals well and rarely requires more than simple wound care. Biopsy results, depending on the nature of analysis required, are typically available within 5 to 10 working days.

Thoracoscopy is a safe procedure when performed by an experienced team, but as with any invasive intervention, certain risks exist:

  • Bleeding at the biopsy site - usually self-limiting
  • Fever and transient inflammatory response, especially after pleurodesis
  • Prolonged air leak if the lung surface is fragile
  • Infection at the port site - uncommon with proper technique
  • Incomplete lung re-expansion - occasionally requiring extended drainage
  • In rare cases, conversion to an open surgical procedure if significant bleeding occurs

Patients with uncorrected bleeding disorders, severe respiratory compromise on the contralateral side, or an obliterated pleural space due to extensive adhesions may not be suitable candidates. These factors are evaluated thoroughly before the procedure is planned.

Thoracoscopy outcomes depend heavily on two things: the quality of the visualization and the experience of the physician interpreting and acting on what is seen. At UMC Hospitals, we offer the best thoracoscopy treatment in Navi Mumbai performed by senior pulmonologists. Our team offers multidisciplinary care to ensure thoracoscopy findings get the required treatment at the earliest.
