Historical developments


Thoracic surgery has an integral role in the management of pleural disease, augmented by significant advancements in both thoracic anaesthesia and operative techniques over the last century. Minimally invasive techniques, in particular, have evolved significantly since they were first performed in 1910 by H.C. Jacobeus using a modified cystoscope. At the turn of the twentieth century, this technique for intrapleural pneumolysis transformed operative treatment for tuberculosis (TB). However, over the following decades, advancements in the medical treatment for TB resulted in a decline in the number of procedures performed. This continued to decline until the advent of video‐assisted devices vastly widened applications in the management of pleural disease and developed into the current video‐assisted thoracic surgery (VATS). Increasingly, such keyhole advancements have allowed interventional pleural procedures to be carried out by chest physicians who perform such procedures under sedation in selected patients.


Thoracic surgery has evolved alongside the development of aseptic techniques, advancements in radiology, transfusion and monitoring techniques. However, the most profound changes to practice have resulted from developments in thoracic anaesthesia.


Thoracic anaesthetic


Thoracic anaesthesia has altered almost unrecognisably from the early days of ether and chloroform. At the time, surgery was time‐limited, because of the physiological effects of the iatrogenic pneumothorax caused when the thoracic cavity is first entered.This posed significant risk, together with the potential for contaminating the contralateral healthy lung in procedures which were largely performed for infection. The ability to secure the airway with a cuffed endotracheal (ET) tube allowed deeper anaesthesia and periods of apnoea during which a more effective procedure could be performed. Further strides were made in the 1930s with the introduction of bronchial blockers which facilitated single‐lung ventilation. A pivotal leap in the management of thoracic patients occurred with the introduction of double lumen ET tubes, in particular the Robertshaw, introduced in 1962, with its wide lumen and moulded curvature which is still widely used today. Safe surgery for pleural disease was further optimised thanks to advances in multi‐modal pain management, mechanical ventilation and novel anaesthetic agents.


Additional advancements in anaesthesia have also influenced the groups now considered for thoracic surgery, including patients who may have previously been seen as poor surgical candidates such as elderly frail patients with multiple comorbidities or complex anatomy. The accurate placement of double lumen ET tubes to enable good lung isolation in patients with difficult airways is now possible with the use of fibreoptic bronchoscopy. Patients with poor preoperative lung function can have their oxygenation maximised during surgery with positive pressure ventilation and patients with multiple comorbidities or at high risk for general anaesthesia can now have complex thoracic intervention performed safely as awake non‐intubated procedures.


Thoracic surgery


The current operative techniques for thoracic surgery have largely been guided by technological advancement. The key pieces of equipment are under a constant process of revision and refinement but, at present, include a rigid 5 or 10 mm diameter thoracoscope with either a 0 or 30 degree angle. A light source and cable are essential, and higher light output is required than with other scopes as blood in the operative field absorbs 50% of the light, darkening the picture. An image processor and camera complete the set up and most recently 3D cameras, which increase the surgical depth of field, have been trialled.
