Summary

Pulmonary resections are key in treating lung neoplasms, with techniques adapted to tumor size and location. Minimally invasive approaches like VATS have replaced open thoracotomy, but intercostal trocar placement can lead to nerve injury and chronic pain.

Robotic-assisted thoracic surgery (RATS) is usually done via a transthoracic (RATS-TT) approach using intercostal trocars. A newer "out of cage" method (RATS-OTC), using subcostal or subxiphoid ports, avoids intercostal access, potentially reducing nerve damage. A French study showed less opioid use and acute pain with RATS-OTC, but chronic pain outcomes are still unknown.

At CHUM, a hybrid RATS technique (RATS-TTH) is also used-intercostal for instruments, but with out-of-cage specimen extraction-to limit intercostal trauma.

Conditions

  • Thoracic Surgery
  • Video-assisted Thoracic Surgery
  • Robotic-assisted Thoracic Surgery

Interventions

OTHER

Evaluation of chronic pain at 3 and 6 months after thoracic surgery

The presence of persistent postoperative pain, defined as ipsilateral chest pain (on the same side as the surgery) occurring at rest and/or with coughing on a daily basis. Assessed by a 'yes' or 'no' response when asked at 3 and 6 months postoperatively.
