Background: Prescription opioids are a major cause of the opioid epidemic. Despite the minimally invasive nature of medical thoracoscopy (MT), data on the efficacy of non-opioid-based pain control after MT is lacking. The purpose of this study is to assess the feasibility and efficacy of a non-opioid-based pain management strategy in patients who underwent MT. Methods: We performed a retrospective analysis of all patients who underwent MT in the Mayo Clinic (Minnesota and Arizona) outpatient setting. We assessed their pain level and the need for analgesia post-MT from August 1, 2019, to May 24, 2021. Results: Forty patients were included. In the first 24 hours, 5/40 (12.5%) reported no pain. Twenty-eight patients out of 40 (70%) reported minor pain (pain scale 1-3), and 7/40 (17.5%) reported moderate pain (pain scale 4-6). No patients reported severe pain. Twenty-two out of 35 patients who experienced discomfort (63%) required acetaminophen, 6/35 patients (17%) required nonsteroidal anti-inflammatory drug, and 7/35 patients (20%) did not require analgesia. Of the 7 patients who had moderate pain, 5 (71%) reported that the moderate pain improved to mild at 72 hours post-MT. Zero patients required opioids, and none reported contacting any provider to manage the pain post-MT. Fourteen patients (78%) who had both parietal pleural biopsies and tunneled pleural catheter placed reported minor pain, 3 patients (17%) reported moderate pain, and 1 patient (6%) experienced no discomfort. Conclusion: MT is well-tolerated by patients with non-opioid-based pain management strategy as needed if there is no absolute contraindication.
