Brief summary (from the registry)
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.
