Brief summary
Follow up of patients who underwent percutaneous cryoneurolysis for pectus excavatum repair (the Nuss procedure) pain management
Detailed description
Follow up of patients after receiving percutaneous cryoneurolysis for pectus excavatum repair, who undergo a physical examination and a neurosensory assessment of the chest wall at 1, 3, 6, 12, and 24 months postoperatively, corresponding to the scheduled follow-up visits. In addition, to evaluate neuropathic pain, chronic pain, and quality of life, patients complete validated questionnaires.
Interventions
Assessment tools include validated questionnaires - the S-LANSS (Self-report Leeds Assessment of Neuropathic Symptoms and Signs, range 0-24, higher scores indicating greater likelihood of neuropathic pain) and the PedsQL™ (Pediatric Quality of Life Inventory, v4.0, Adolescent/Young Adult Report, range 0-100, higher scores indicating better health-related quality of life) - together with the Patient Self-Assessment Sensory Scale (range 0-10, 0 indicating no sensitivity and 10 indicating normal sensitivity) and a structured physical examination of thoracic sensitivity. These tools are administered at pre-specified follow-up timepoints. The physical examination assesses four sensory modalities corresponding to specific afferent fibre classes of the intercostal nerves: cold thermal sensation (Aδ fibres, ice-water contact, 4-10°C), warm thermal sensation (C fibres, \~40°C water), light touch (Aβ fibres, camel-hair brush), and pressure sensitivity (Aβ fibres, Von Frey filament 5.07/10g)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Self-report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) questionnaire results | The same patients are followed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how S-LANSS score evolve over time. | To assess the incidence of neuropathic pain using the validated S-LANSS (Self-report Leeds Assessment of Neuropathic Symptoms and Signs) scale, administered at the scheduled follow-up visits. The S-LANSS score ranges from 0 to 24, with higher scores indicating greater likelihood and severity of neuropathic pain (a score ≥12 is suggestive of pain of predominantly neuropathic origin |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pediatric Quality of Life Inventory (PedsQL) questionnaire | The same patients are assessed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how quality of life evolve over time. | To describe the quality of life of patients using a specific validated questionnaire appropriate for adolescents and young adults (Pediatric Quality of Life Inventory - PedsQL™ version 4.0 for adolescents and young adults). The PedsQL total score ranges from 0 to 100, with higher scores indicating better health-related quality of life. |
| chronic postoperative pain (CPSP) assessment | The same patients are followed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how chronic pain evolve over time. | To describe the incidence of chronic postoperative pain (CPSP), defined as persistence of pain beyond one month, according to two parameters: direct measurement using the NRS (Numeric Rating Scale) for pain intensity, and indirect measurement through consumption of analgesic medications included in the institutional current protocol (acetaminophen and NSAIDs). The NRS ranges from 0 (no pain) to 10 (worst possible pain), with higher scores indicating greater pain intensity. |
| sensitivity recovery using the Patient Self-Assessment Sensory Scale | The same patients are assessed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how sensitivity recovery evolve over time. | To describe the evolution of thoracic thermotactile hypoesthesia over time, starting from the day of cryoneurolysis, using the Patient Self-Assessment Sensory Scale. The scale ranges from 0 to 10, with 0 indicating no sensitivity (complete anaesthesia) and 10 indicating maximal/normal sensitivity, with higher scores indicating better (more complete) sensory recovery. |
