Brief Summary
The main objective study is to compare the use of the cryoSPHERE probe to the standard-of-care method for pain management of patients receiving robotic-assisted thoracoscopic surgery, including reductions in opioid pain medication use and the development of post-surgical morbidity.

Nerve Block Using Liposomal Bupivacaine and cryoSPHERE Ablation
EXPERIMENTALThe experimental group (75 participants) will undergo intercostal nerve block using liposomal bupivacaine and the cryoSPHERE ablation of intercostal nerves during robotic-assisted thoracoscopic operation at Houston Methodist Hospital.
Historical Controls
OTHERA total of 75 propensity score-matched historical controls will be selected from the pool of patients who had standard intercostal nerve block using liposomal bupivacaine alone at Houston Methodist Hospital from January 1, 2017 through January 1, 2022, inclusively.
Interventions
The cryoSPHERE probe will be introduced through a thoracoscopic port and placed inferior to each rib level and 2cm lateral and away from the sympathetic chain when clearly visible or 4cm lateral and away from the spine when the sympathetic chain is not visible. Levels to be ablated are intercostal spaces 3-9. Each intercostal nerve will undergo cryogenic ablation of -70 degrees Celsius for 120 seconds. The probe will be firmly pushed against the nerve for 120 seconds and will only be released from the nerve when the probe has thawed. Axons within the intercostal nerve that send pain signals will be destroyed distal to the cryoablation site. However, the tubules structures (epineurium, perineurium, and endoneurium) of the nerve will remain intact, allowing the axons to regenerate and nerve function to resume after one to three months.
A long needle will be introduced through a thoracoscopic port, and in each intercostal space (1-11), 1ml of liposomal bupivacaine will be injected onto the intercostal nerves to induce intercostal nerve blockage.
Eligibility Criteria
You may qualify if:
- Male and female patients 18-90 years of age
- Diagnosis requiring robotic-assisted thoracoscopic surgery
- Daily opioid use for at least 30 days consecutively at any point during the last 12 months prior to surgery or using opioids at the time of study enrollment
- Experimental group only: agreement and consent to comply with all aspects of the study protocol and data collection, including follow-up contact.
You may not qualify if:
- Previous major surgery at the operative site (thoracotomy)
- Allergy to aluminum
- Allergy to plastics
- Allergy to bupivacaine
- Shingles disease
- Demyelinating illnesses
- Involvement with other interventional studies
