Purpose : Postoperative pain for the minimally invasive repair for pectus excavatum (MIRPE) is a critical issue which leads to long postoperative length of stay and requirement of high dose of opiates. The aim of this study was to evaluate the efficacy of intercostal cryoablation during the MIRPE.

Methods : We retrospectively analyzed 18 patients who underwent the MIRPE with intercostal cryoablation or epidural PCA from January to August 2020. The opioid oral morphine milligram equivalent was used to calculate the dosage of opioid agents.

Results : In total, 15 was male and the median age was 15 years (7 – 28). The median postoperative length of stay was 4 days (2 – 6) and the median oral morphine milligram equivalent was 455 mg (0 – 1306). Intercostal cryoablation was performed in 8 patients and epidural PCA was performed in 10 patients. Intercostal cryoablation group had significant shorter postoperative length of stay and lower oral morphine milligram equivalent compared to epidural PCA group (3 days versus 5 days; P = 0.001, 25 mg versus 774 mg; P < 0.001).

Conclusion : Compared to epidural PCA, intercostal cryoablation during the MIRPE reduces length of stay and requirement of opioid dose. Intercostal cryoablation could be a safe and effective method for pain control.
