The aim of the study is to analyze the prevalence of chronic pain, including neuropathic pain following operations for funnel chest deformity of the anterior chest wall in children.
Pectus excavatum is the most common congenital deformity of the anterior chest wall. The minimally invasive repair of pectus excavatum (MIRPE), is the standard surgical treatment. Intraoperative intercostal nerve cryoanalgesia (INC) has emerged as an important advance in postoperative pain management after MIRPE, reducing opioid consumption and length of hospital stay. Potential complications of intercostal nerve cryoanalgesia include transient sensory disturbances (hypoesthesia and paresthesia), neuropathic pain, local hematoma formation, infection, and injury to adjacent structures. Most sensory abnormalities are temporary and resolve spontaneously within several months.
We conducted a prospective observational before-and-after cohort study. The aim of the study was to analyze the prevalence of chronic pain, including neuropathic pain following operations for funnel chest deformity of the anterior chest wall in children with and without cryoanalgesia.
