Brief Summary
Intercostal cryoanalgesia is a technique that allows extensive and prolonged analgesia of the hemithorax. The aim of this study is to demonstrate the efficacy of intercostal cryoanalgesia as an adjunct to a single-injection paravertebral block for the prevention of chronic thoracic pain after VATS lung resection surgery.

Study Arms (2)
Intercostal cryoanalgesia AND single-injection paravertebral block
EXPERIMENTAL* Videothoracoscopic-guided single-injection paravertebral block at T5 with 0.4 mL/kg of Bupivacaine 0.5% with adrenalin 5 mcg/mL (maximum 40 mL) at the beginning of surgery * Cryoanalgesia 5 cm lateral to the neuraxial, on the inferior costal border, CO2 at (-)50C to (-)70C for 2 minutes, repeated on 7 costal levels (T3-T9), after the lung resection and before chest closure.
Single-injection paravertebral block
ACTIVE COMPARATOR-Videothoracoscopic-guided single-injection paravertebral block at T5 with 0.4 mL/kg of Bupivacaine 0.5% with adrenalin 5 mcg/mL (maximum 40 mL) at the beginning of surgery
Interventions

Paravertebral block with Bupivacaine 0.5%
Eligibility Criteria
You may qualify if:
- Patients scheduled for elective anatomical pulmonary resection (anatomical segmentectomy, lobectomy or bilobectomy) by VATS for lung cancer
- American Society of Anesthesiologists (ASA) score 1-3
You may not qualify if:
- Contraindication to the paravertebral block (coagulopathy, discontinuous paravertebral space, impossible thoracoscopic visualization of the paravertebral space)
- Contraindication to intercostal cryoanalgesia (cold urticaria, cryoglobulinemia)
- Epidural analgesia preferred (high risk of thoracotomy, marginal lung function)
- Surgical criteria (conversion to thoracotomy, non anatomical wedge resection)
- Preoperative thoracic or shoulder pain on the operated side
- Known allergy to acetaminophen, celecoxib, sulfa, or both hydromorphone and morphine
- History of thoracic surgery on the operated site
- Regular use of opioids or medication with effects against neuropathic pain (tricyclics, gabapentinoids, duloxetine, venlafaxine)
- Inability to understand pain scales or to communicate clearly despite adequate teaching
- Contraindication to non-steroidal anti-inflammatory drugs (renal filtration rate \< 60 mL/min, active gastric ulcer)
- Pregnancy
- Patient refusal to participate
