IntroductionEpidural analgesia is currently considered the gold standard in postoperative pain management for the minimally invasive Nuss procedure for pectus excavatum. Alternative analgesic ...strategies (eg, patient-controlled analgesia and paravertebral nerve block) fail in accomplishing adequate prolonged pain management. Furthermore, the continuous use of opioids, often prescribed in addition to all pain management strategies, comes with side effects. Intercostal nerve cryoablation seems a promising novel technique. Hence, the primary objective of this study is to determine the impact of intercostal nerve cryoablation on postoperative length of hospital stay compared with standard pain management of young pectus excavatum patients treated with the minimally invasive Nuss procedure.Methods and analysisThis study protocol is designed for a single centre, prospective, unblinded, randomised clinical trial. Intercostal nerve cryoablation will be compared with thoracic epidural analgesia in 50 young pectus excavatum patients (ie, 12–24 years of age) treated with the minimally invasive Nuss procedure. Block randomisation, including stratification based on age (12–16 years and 17–24 years) and sex, with an allocation ratio of 1:1 will be performed.Postoperative length of hospital stay will be recorded as the primary outcome. Secondary outcomes include (1) pain intensity, (2) operative time, (3) opioid usage, (4) complications, including neuropathic pain, (5) creatine kinase activity, (6) intensive care unit admissions, (7) readmissions, (8) postoperative mobility, (9) health-related quality of life, (10) days to return to work/school, (11) number of postoperative outpatient visits and (12) hospital costs.Ethics and disseminationThis protocol has been approved by the local Medical Ethics Review Committee, METC Zuyderland and Zuyd University of Applied Sciences. Participation in this study will be voluntary and informed consent will be obtained. Regardless of the outcome, the results will be disseminated through a peer-reviewed international medical journal.Trial registration numberNCT05731973.
A male patient in his early 30s underwent minimally invasive repair of pectus excavatum. According to standard Nuss bar procedure, a 30-degree thoracoscope was introduced through a right midaxillary ...10 mm trocar in the 4th intercostal space. Two bars and five stabilisers were placed in a retromuscular position. After discharge, the patient experienced right upper back pain requiring prolonged opioid usage for three months and right scapular winging limiting functional activities. After conservative treatment with physiotherapy for 11 months, the patient still suffered from residual scapula alata with pain and muscle weakness. On suspicion of long thoracic nerve neuropraxia related to the thoracoscope placement, an electromyogram was conducted 16 months following surgery, revealing mild polyphasic potentials of the serratus anterior muscle without abnormal muscle unit action potential. After extended conservative therapy for another year, physical examination 28 months after surgery showed almost complete resolution of scapular winging.
BackgroundPectus excavatum often imposes significant burden on the patients' quality of life. However, despite the known biopsychosocial effects, the deformity remains underappreciated. Patient ...reported outcome measures can be used to measure and appreciate results from a patient's perspective. The pectus excavatum evaluation questionnaire (PEEQ) is the most employed disease specific instrument to measure patient-reported outcome measures (PROMs). A translation and linguistic validation of this questionnaire is presented for its use in the Dutch pediatric pectus excavatum population. By providing an insight in our translation process, we want to encourage other researchers to perform translations to other languages to make the questionnaire available to clinicians and researchers worldwide. MethodsThe 22-item PEEQ was translated and adapted according to the leading guidelines for the translation of patient reported outcome measures. Conceptual equivalence and cultural adaptation were emphasized. ResultsOne forward translation was produced through reconciliation of two forward translations. Back translation resulted in 15 identical items, as well as 6 literal, and 1 conceptual discrepancy. The latter was expected as during the forward translation a more culturally appropriate translation was chosen. Ten patients were involved during the cognitive debriefing process, following which one item was revised and the final Dutch version was established. ConclusionsWe provide a culturally appropriate and linguistically validated Dutch version of the PEEQ.
Pectus excavatum is the most common congenital anterior chest wall deformity. Currently, a wide variety of diagnostic protocols and criteria for corrective surgery are being used. Their use is ...predominantly based on local preferences and experience. To date, no guideline is available, introducing heterogeneity of care as observed in current daily practice. The aim of this study was to evaluate consensus and controversies regarding the diagnostic protocol, indications for surgical correction, and postoperative evaluation of pectus excavatum.
The study consisted of 3 consecutive survey rounds evaluating agreement on different statements regarding pectus excavatum care. Consensus was achieved if at least 70% of participants provided a concurring opinion.
All 3 rounds were completed by 57 participants (18% response rate). Consensus was achieved on 18 of 62 statements (29%). Regarding the diagnostic protocol, participants agreed to routinely include conventional photography. In the presence of cardiac impairment, electrocardiography and echocardiography were indicated. Upon suspicion of pulmonary impairment, spirometry was recommended. In addition, consensus was reached on the indications for corrective surgery, including symptomatic pectus excavatum and progression. Participants moreover agreed that a plain chest radiograph must be acquired directly after surgery, whereas conventional photography and physical examination should both be part of routine postoperative follow-up.
Through a multiround survey, international consensus was formed on multiple topics to aid standardization of pectus excavatum care.
