Background Nuss procedure for pectus excavatum is a minimally invasive, but painful procedure. Recently, intercostal nerve cryoablation has been introduced as a pain management technique.

Materials and Methods In this cohort study, we compared the efficacy of multimodal pain management strategies in children undergoing a Nuss procedure. The effectiveness of intercostal nerve cryoablation combined with patient-controlled systemic opioid analgesia (PCA) was compared with continuous epidural analgesia (CEA) combined with PCA. The study was conducted between January 2019 and July 2022. Primary outcome was length of stay (LOS), and secondary outcomes were operation room time, postoperative pain, opioid consumption, and gabapentin use.

Results Sixty-six consecutive patients were included, 33 patients in each group. The cryoablation group exhibited lower Numeric Rating Scale (NRS) pain scores on postoperative day 1 and 2 (p = 0.002, p = 0.001) and a shorter LOS (3 vs. 6 days (p < 0.001). Cryoablation resulted in less patients requiring opioids at discharge (30.3 vs. 97.0%; p < 0.001) and 1 week after surgery (6.1 vs. 45.4%; p < 0.001)). In the CEA group, gabapentin use was more prevalent (78.8 vs. 18.2%; p < 0.001) and the operation room time was shorter (119.4 vs. 135.0 minutes; p < .010). No neuropathic pain was reported.

Conclusions Intercostal nerve cryoablation is a superior analgesic method compared with CEA, with reduced LOS, opioid use, and NRS pain scores. The prophylactic use of gabapentin is redundant.

Given the nature of this research, not interfering with the treatment of patients, an official waiver of ethical approval (W20_235 # 20.271) was granted by the Medical Research Ethics Committee (METC) of the Amsterdam UMC, Amsterdam, the Netherlands (Chairperson MSc. O. Harlaar) on 28 May 2020. Informed consent was obtained from all individual patients (or their parents) included in this study.
