Comparing Chronic Pain After Lung Surgery Using Three Robotic Approaches RATS-TT, RATS-OTC, and Hybrid RATS Techniques

What this Trial Is About

This research aims to compare chronic pain outcomes following different robotic-assisted thoracic surgery RATS techniques used for pulmonary resections in patients with lung tumors. These surgeries are important for treating lung neoplasms, with approaches tailored to tumor size and location. Minimally invasive surgeries like video-assisted thoracic surgery VATS have reduced acute pain but chronic pain remains a concern. The study evaluates three RATS methods the transthoracic approach RATS-TT, the out of cage technique RATS-OTC that avoids intercostal nerve injury, and a hybrid method RATS-TTH used at CHUM. Participants will have pulmonary resection surgery using one of the three RATS techniques. RATS-TT uses intercostal trocars for instruments and specimen removal, RATS-OTC avoids intercostal access by using subcostal or subxiphoid ports, and RATS-TTH combines intercostal instrument access with out-of-cage specimen extraction to reduce nerve trauma. The study observes pain at 3 and 6 months post-surgery to assess chronic pain incidence. These approaches are compared to understand their effects on persistent pain after surgery. Participants will be followed up at 3 and 6 months after surgery to assess persistent postoperative pain, including chest pain at rest or with coughing. Pain will be evaluated by patient response, and additional assessments include neuropathic pain components, overall recovery, analgesic use, opioid consumption, hospital stay length, residual pain intensity, and presence of dysesthesia. The study collects data on these outcomes to better understand long-term pain following different surgical techniques for lung tumor removal.
