Management of Pulmonary and Mediastinal Pathology by Uniportal Video-Assisted Thoracic Surgery (Uniportal VATS)

Management of Pulmonary and Mediastinal Pathology by Uniportal Video-Assisted Thoracic Surgery (Uniportal VATS)

What is VATS?

Video-assisted thoracic surgery (VATS) is minimally invasive thoracic surgery. During a video-assisted thoracic surgery procedure, a tiny camera and surgical instruments are inserted into your chest through a small incision in your chest wall. The thoracoscope transmits images of the inside of your chest onto a video monitor, guiding the surgeon in performing the procedure. Its main benefit has been the avoidance of a thoracotomy incision or median sternotomy. This allows a shorter operating time, less postoperative complications, and earlier return to normal activity compared to open surgery. The average length of hospital stay is 1-3 days when compared to 5-7 days for open surgery.


In the past, the surgeons had to make 3-4 incisions for camera and surgical instrument insertions. This so-called baseball diamond approach aligns the camera and instruments to perform a surgery. Although the incisions are smaller than open surgery, the patient still has significant pain during the post-operative period due to the presence of nerves underneath the lower edge of each rib and therefore many small incisions can lead to severe pain.

Uniportal VATS technique

Ongoing improvements in techniques and instruments for video-assisted thoracic surgery (VATS) has made minimally-invasive uniportal VATS possible. The surgeon has to make only one 3-4 centimeters incision in the chest. The surgeon who performs this technique should have comprehensive experience with VATS procedure. With the uniportal VATS technique, the patient will experience less pain with the same successful outcome as multiple port VATS1-4.

Uniportal VATS technique can be used in various conditions where pulmonary and mediastinal surgeries are required. There are some limitations in the conditions such as metastatic lung cancer, malignant mesothelioma, and chronic empyema thoracis. As with any novel technique, the success factor is highly experienced surgeons. Bangkok hospital offers comprehensive medical, surgical, and therapeutic services. With a world-class medical staff, we provide innovative technologically advanced care for each patient.
