Minimally invasive lung surgery is also referred to as “keyhole surgery”. Minimally invasive approach requires two small incisions about 1 cm in size in the lower aspect of the chest wall. There is a third incision which is about 3 cm in the upper aspect of the chest which allows the surgeon to introduce instruments in the chest and also remove the resected lung through the small incision. This incision in technical terms is still called thoracotomy but differs compared to traditional open thoracotomy in not spreading ribs and not cutting large chunks of chest wall muscles. Surgery is done under general anaesthesia. The majority of time you will not have a urinary catheter. The entire operation is performed under the guidance of video assistance which is obtained by introducing a camera/telescope through one of the bottom holes. This camera provides a significantly magnified view of structure detailing anatomy. There is no rib spreading or cutting with this approach which makes it quite patient friendly in terms of postoperative pain and recovery. Most surgeries will take about 1-1.5 hrs. Patients are awake straight after surgery and transferred to the recovery room prior to sending them back to the ward. You will have a tube coming out of your chest connected to the drain bottle. This drain is left in deliberately to assist removal of any residual blood/fluid that accumulates,or for evacuation of air that may leak from suture lines from your lung. Majority of drains are removed after 48 hrs and patients are discharged home with pain killers.
During your hospitalization, your pain is very well managed by the anaesthetist and nurses looking after you . Sometimes we involve a pain team but generally this is not necessary. Your pain is controlled with either button controlled system or a nerve block introduced in your back. You will also get oral pain killers but they can sometimes have significant side effects like nausea, vomiting and constipation.
