RESUMEN
PURPOSE: The current standard method for pectus excavatum (PE) repair is the Nuss procedure. One major postoperative complication is the displacement of the implanted metal bar, which is used to remodel the chest wall. Blocking the possible ways that the bar can be displaced with the use of stabilizers and peri/intracostal sutures has reduced the incidence of bar displacement. Despite the modifications, bar dislocation is often reported. We adopted the medial position stabilizer placement method and imposed no postoperative restrictions. In this study, we analyzed the bar dislocation rate with this modification and concurrent postoperative full activity. METHODS: Nuss procedure modification where stabilizers are placed bilaterally in the medial location was done on patients irrespective of age and Haller index greater than 3.25. A single bar was used for all patients. Cryoanalgesia was performed on every patient. No postoperative restrictions were imposed on the patients. Full immediate activities, including sports, were allowed. RESULTS: 114 patients (103 male, 11 female) were analyzed from 2016 to 2023. The median age was 15 years old. There was zero incidence of bar displacement. The combined incidence of other postoperative complications was 4%: 2 wound infections and 2 hematoma formations, both needing incision and drainage. CONCLUSION: Bilateral medial stabilizer placement resulted in no incidence of bar dislocation. Return to immediate full activities after the Nuss procedure did not appear to increase the incidence of bar displacement if stabilizers were placed medially.

ABSTRACT: Coexisting congenital cystic adenomatous malformation of the lungs and severe pectus excavatum (PE) is an uncommon presentation that poses significant management challenges. Conventionally managed in a staged manner, there are increasing reports of superior outcomes with single-staged concurrent repair with minimally invasive techniques (video-assisted thoracoscopic surgery [VATS] and minimally invasive repair of PE [MIRPE]). The outcome of a single-stage open repair for both anomalies has not been previously reported to the best of our search. We report the successful single-stage management of a 9-month-old infant with both anomalies who had an open lobectomy and modified Ravitch procedure. We aim to report the feasibility and safety of a single-stage concurrent repair of both conditions using open techniques, as VATS and MIRPE are not readily available in our environment.

Anterior chest wall instability as a result of sternocostal non-union is a rare complication but can give rise to invalidating pain and cardiac arrhythmias. A woman in her 40s was referred to us with anterior chest wall pain and instability after a modified Ravitch procedure. Sternocostal pseudoarthrosis was seen for which multiple operations were performed which were complicated by low-grade infections. A patient-specific three-dimensional modelled and printed prostheses was used in an operation to both lift the sternum for pectus correction and to reconnect the sternum and the sternal costal junction to regain anterior chest wall stability.

BACKGROUND: Lung transplantation (LTx) is a crucial therapeutic strategy for patients suffering from end-stage respiratory diseases, necessitating precise donor-recipient size matching to ensure optimal graft function. While standard allocation protocols rely on predicted lung capacity based on factors such as sex, age, and height, a subset of patients with respiratory diseases presents an additional challenge - thoracic or vertebral deformities. These deformities can complicate accurate volume predictions and may impact the success of lung transplantation. METHODS: In this retrospective cohort study of patients who underwent LTx at Tohoku University Hospital between January 2007 and April 2022, with follow-up until October 2022, the primary objective was to assess the influence of thoracic and vertebral deformities on perioperative complications, emphasizing interventions, such as volume reduction surgery. The secondary objective aimed to identify any noticeable impact on long-term prognoses in recipients with these deformities. RESULTS: Of 129 LTx recipients analyzed, 17.8% exhibited thoracic deformities, characterized by pectus excavatum, while 16.3% had vertebral deformities. Perioperative complications, requiring delayed chest closure, tracheostomy, and volume reduction surgery, were more prevalent in the deformity group. Thoracic deformities were notably associated with the need for volume reduction surgery. However, long-term prognoses did not differ significantly between patients with deformities and those without. Vertebral deformities did not appear to significantly impact perioperative or long-term outcomes. CONCLUSIONS: This study highlights the prevalence of thoracic deformities in LTx recipients, correlating with increased perioperative complications, particularly the potential need for volume reduction surgery. Importantly, these deformities do not exert a significant impact on long-term prognoses. Additionally, patients with vertebral deformities, such as scoliosis and kyphosis, appear to be manageable in the context of LTx.

This paper reports the case of a female patient who underwent minimally invasive repair of pectus excavatum (MIRPE) in another service that evolved with bar rotation and cardiac perforation caused by the left stabilizer. The unique and frightening aspect of the case is that despite having the stabilizer inside the ventricle, the patient was oligosymptomatic: occasional chest pain and respiratory discomfort. Preoperative imaging showed rotation of the bar with stabilizers within the thoracic cavity. During surgery, intense ossification was observed around the prosthesis and it was noted that the left stabilizer had perforated the patient's left ventricle. Cardiac repair required a Clamshell incision and cardiopulmonary bypass. This case reinforces the validity of late radiological follow-up after MIRPE in an attempt to avoid this type of event, and the need to reevaluate the use of stabilizers perpendicular to the bar since they are not safe to prevent rotation of these implants.

Pectus defects are a group of congenital conditions found in approximately 1 in 250 people, where the sternum is depressed back towards the spine (excavatum), protrudes forwards (carinatum) or more rarely is a mixture of both (arcuatum or mixed defects). For the majority of patients, it is well tolerated, but some patients are affected psychologically, physiologically or both. The deformity becomes apparent at a young age due to the growth of the ribs and the cartilage that links them to the sternum. The majority of defects are mild and are well tolerated, i.e. they do not affect activity and do not cause psychological harm. However, some young people develop lower self-esteem and depression, causing them to withdraw from activities (such as swimming, dancing) and from interactions that might 'expose' them (such as sleepovers, dating, going to the beach and wearing fashionable clothes). This psychological harm occurs at a crucial time during their physical and social development. A small number of patients have more extreme depression of their sternum that impedes their physiological reserve, which can occur when engaging in strenuous exercise (such as running) but can also limit moderate activity such as walking and climbing stairs. The effects can be so extreme that symptoms occur at rest or cause life-threatening compression of the major blood vessels and organs. The group of patients with physiological impairment usually also suffer from low self-esteem and depression. This paper summarizes the current evidence for the different treatment strategies for this condition, including supportive care, psychological support and non-surgical techniques including bracing and vacuum bell therapy. We also consider surgical techniques including the Ravitch procedure, the Nuss procedure (minimally invasive repair of pectus excavatum), pectus implants and other rare procedures such as Pectus Up. For the majority of patients, supportive care is sufficient, but for a minority, a combination of the other techniques may be considered. This paper also outlines best practice guidance for the delivery of such therapies, including standardized assessment, consent to treatment, audit, quality assurance and long-term support. All the interventions have risks and benefits that the patient, parents and clinicians need to carefully consider and discuss when deciding on the most appropriate course. We hope this evidence review of 'Best Practice for Pectus' will make a significant contribution to those considerations and help all involved, from patients to national policy makers, to deliver the best possible care.

OBJECTIVES: Pectus excavatum, or funnel chest, causes both physical and psychosocial issues, affecting health-related quality of life. However, the literature on how funnel chest affects daily living prior to corrective surgery is sparse. Therefore, the study aimed to describe the experiences of living with funnel chest prior to correctional surgery. MATERIALS AND METHODS: The study had a qualitative exploratory design. Consecutive sampling was applied in which all individuals from a single cardiothoracic department scheduled for the minimally invasive repair of pectus excavatum were asked to participate. Nineteen participants, 17 men and two women, participated in the study. Individual telephone interviews were conducted from February 2020 until April 2021. The interviews were analyzed with qualitative content analysis using an inductive approach. RESULTS: The overall theme "To have or not to have a cavity in my chest, it could make a difference" was interpreted as the latent meaning of the participants' experiences. The theme included two subthemes with three categories each. The subtheme "The funnel chest puts a weight on my shoulders" describes the heavy burden the funnel chest places on the participants. The second subtheme, "This is me, but I want to change my future", describes that participants see the funnel chest as a part of themselves; nevertheless, they look forward to surgery and a life without it. CONCLUSION: The results emphasize the heavy burden funnel chest causes and the great limitations it places on the individual. It also highlights the importance of surgery and the hope for a better future for individuals with funnel chest.

BACKGROUND: Recent data highlight the internet's pivotal role as the primary information source for patients. In this study, we emulate a patient's/caregiver's quest for online information concerning chest deformities and assess the quality of available information. METHODS: We conducted an internet search using combination of the terms "pectus excavatum," "pectus excavatum surgery," "funnel chest," "pectus excavatum repair" and identified the first 100 relevant websites from the three most popular search engines: Google, Yahoo, and Bing. These websites were evaluated using the modified Ensuring Quality Information for Patients (EQIP) instrument. RESULTS: Of the 300 websites generated, 140 (46.7%) were included in our evaluation after elimination of duplicates, non-English websites, and those targeting medical professionals. The EQIP scores in the final sample ranged from 8 to 32/36, with a median score of 22. Most of the evaluated websites (32.8%) originated from hospitals, yet none met all 36 EQIP criteria. DISCUSSION: None of the evaluated websites pertaining to pectus excavatum achieved a flawless "content quality" score. The diverse array of websites potentially complicates patients' efforts to navigate toward high-quality resources. Barriers in accessing high-quality online patient information may contribute to disparities in referral, patient engagement, treatment satisfaction, and overall quality of life.

This novel report presents the first known case, to our knowledge, of a 16-year-old male patient who experienced intraventricular thrombosis and pulmonary embolism after a Nuss procedure for pectus excavatum, attributed to chronic bar displacement. Two years after the operation, the patient experienced post-exercise cough and hemoptysis, which led to his admission. Imaging revealed pulmonary embolism, thrombosis in the right ventricular outflow tract, and lung infiltrative lesions. We hypothesize that the chronic bar displacement led to its embedment in the right ventricle, resulting in thrombus formation, which subsequently contributed to partial pulmonary embolism. Surgery revealed the bars' intrusion into the right ventricle and lung. This case highlights the risk of severe complications from bar displacement in the Nuss procedure, which necessitates long-term follow-up evaluation, caution against strenuous activities after surgery, and use of thoracoscopic guidance during bar implantation and removal. It underscores the importance of vigilant evaluation for late-stage complications in patients with respiratory distress or thrombosis after a Nuss procedure.

BACKGROUND Computer-aided design (CAD) has been used in the Nuss procedure to determine the bar length and shape. Despite computer aid, the shape and design remain quite intuitive. We tested a new algorithm to determine the optimal bar shape. MATERIAL AND METHODS The normal sterno-vertebral distance was defined on computed tomography (CT) scans of patients without pectus excavatum (PEx) at the same level where the deepest depression was found on CT scans of 97 patients with PEx. Four points were marked on the CT scan of 60 patients with PEx at the deepest deformity: P1: edge of the vertebra; P2: edge of the deformity; P3: the expected contact point of the bar and the rib; and P4: the expected end of the bar. The algorithm generated 3 circles upon these points, and the fusion of the arcs drew the line of the ideal bar. Corrected and normal sterno-vertebral distance values were compared with the Mann-Whitney U test. Ten bars were bent manually guided by a 1: 1 printout of the designed bar and were implanted in 10 adolescents. RESULTS The shortest sterno-vertebral distance was 3 cm below the intermammillary line in PEx patients. The normal mean sterno-vertebral distance at this level was 10.16±1.35 cm in non-PEx patients. The mean virtually corrected sterno-vertebral distance was 10.28±1.27 cm. No significant difference was found (P=0.44). The bars were seamless and were successfully implanted. No bar needed adjustment, the operation time was shorter, and the patient satisfaction score was 9.4/10. CONCLUSIONS With our new algorithm, an optimal Nuss bar can be designed.

BACKGROUND: Pectus arcuatum, also known as horns of steer anomaly or Currarino-Silverman Syndrome, is a distinct chest wall anomaly characterized by severe manubriosternal angulation, a shortened sternum, and mild pectus excavatum. The anomaly is typically repaired using open techniques, employing orthopedic fixation devices. Here, we report the results of a minimally invasive hybrid procedure to repair pectus arcuatum. METHODS: The procedure combines a standard Nuss procedure to correct the depressed sternum with a short upper chest (in boys) or inter-mammary (in girls) incision for bilateral subperichondrial resection of the upper costal cartilages, osteotomy, and correction of the manubrial angulation. The medical records of all patients who underwent the procedure over the last 10 years were reviewed. RESULTS: Five patients, 3 boys and 2 girls, aged 14 to 17 years, underwent the procedure. Three patients had their pectus bars removed 3-4 years after repair. Follow-up after correction ranged from 6 months to 7 years. Good correction resulted in all patients achieving recovery without complications and recurrence. To date, all patients have been satisfied with their results. CONCLUSIONS: The minimally invasive hybrid procedure adequately corrects pectus arcuatum with minimal scarring and high satisfaction.

BACKGROUND: Pectus excavatum (PE) severity and surgical candidacy are determined by computed tomography (CT)-delineated Haller Index (HI) and Correction Index (CI). White light scanning (WLS) has been proposed as a non-ionizing alternative. The purpose of this retrospective study is to create models to determine PE severity using WLS as a non-ionizing alternative to CT. METHODS: Between November 2015 and February 2023, CT and WLS were performed for children ≤18 years undergoing evaluation at a high-volume, chest-wall deformity clinic. Separate quadratic discriminate analysis models were developed to predict CT HI ≥ 3.25 and CT CI ≥ 28% indicating surgical candidacy. Two bootstrap forest models were trained on WLS measurements and patient demographics to predict CT HI and CT CI values then compared to actual index values by intraclass correlation coefficient (ICC). RESULTS: In total, 242 patients were enrolled (86.4% male, mean [SD] age 15.2 [1.3] years). Quadratic discriminate analysis models predicted CT HI ≥ 3.25 with specificity = 91.7%, PPV = 97.7% (AUC = 0.91), and CT CI ≥ 28% with specificity = 92.3%, PPV = 93.5% (AUC = 0.84). Bootstrap forest model predicted CT HI with training dataset ICC (95% CI) = 0.91 (0.88-0.93, R2 = 0.85) and test dataset ICC (95% CI) = 0.86 (0.71-0.94, R2 = 0.77). For CT CI, training dataset ICC (95% CI) = 0.91 (0.81-0.93, R2 = 0.86) and test dataset ICC (95% CI) = 0.75 (0.50-0.88, R2 = 0.63). CONCLUSIONS: Using noninvasive and nonionizing WLS imaging, we can predict PE severity at surgical threshold with high specificity obviating the need for CT. Furthermore, we can predict actual CT HI and CI with moderate-excellent reliability. We anticipate this point-of-care tool to obviate the need for most cross-sectional imaging during surgical evaluation of PE. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Study of Diagnostic Test.

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.

PURPOSE: The utility of pulmonary function testing (PFT) in pectus excavatum (PE) has been subject to debate. Although some evidence shows improvement from preoperative to postoperative values, the clinical significance is uncertain. A high failure-to-completion rate for operative PFT (48%) was identified in our large institutional cohort. With such a high non-completion rate, we questioned the overall utility of PFT in the preoperative assessment of PE and sought to evaluate if other measures of PE severity or cardiopulmonary function could explain this finding. METHODS: Demographics, clinical findings, and results from cardiac MRI, PFT (spirometry and plethysmography), and cardiopulmonary exercise tests (CPET) were reviewed in 270 patients with PE evaluated preoperatively between 2015 and 2018. Regression modeling was used to measure associations between PFT completion and cardiopulmonary function. RESULTS: There were no differences in demographics, symptoms, connective tissue disorders, or multiple indices of pectus severity and cardiac deformation in PFT completers versus non-completers. While regression analysis revealed higher RVEF, LVEF, and LVEF-Z scores, lower RV-ESV/BSA, LV-ESV/BSA, and LV-ESV/BSA-Z scores, and abnormal breathing reserve in PFT completers vs. non-completers, these findings were not consistent across continuous and binary analyses. CONCLUSIONS: We found that PFT completers were not significantly different from non-completers in most structural and functional measures of pectus deformity and cardiopulmonary function. Inability to complete PFT is not an indicator of pectus severity.

Pectus excavatum, also called sunken chest, is the most common deformation of the sternum (90%). The deformation is caused by the depression of the sternum and costal cartilages, which causes reduction of the chest cavity and dysfunction of cardio-pulmonary systems in it. Sunken chest is more common in males than females, prevalence is 5/1. Most of the cases appear in the first year of life, however severity of the pathology is formed during puberty. Etiopathogenesis, genetic factors, and associated diseases of Pectus Excavatum are various and are still the subject of study. The manifestation of the disease is determined by the degree of chest deformation, which is calculated using the "Haller index". Providing that a high degree of deformation can lead to pathological functioning of the cardiovascular and respiratory systems. The treatment of this condition is an urgent, complex, and developing issue. The main method of treatment for sunken chest is surgical intervention; However, in cases of mild degrees of the mentioned deformation, different approaches are used. Our goal is to discuss contrasting treatment techniques and present our improved repairing technique for sunken chest, which is performed in Georgia.

Video-assisted thoracic surgery (VATS) is currently used for the repair of pectus excavatum. Analgesia after thoracic surgery can be provided with nerve blocks, intravenous drugs, or neuraxial techniques. Serratus posterior superior intercostal plane block (SPSIPB) is a novel interfascial plane block and it is performed between the serratus posterior superior muscle and the intercostal muscles at the level of the second and third ribs. In this case, we present our successful analgesic experience with SPSIPB in a patient who underwent minimally invasive pectus excavatum repair with a VATS technique.

BACKGROUND: The minimally invasive repair of pectus excavatum (MIRPE) is associated with significant postoperative pain and opioid use. The objective of this study was to determine the effect of intercostal nerve cryoablation (Cryo) on inpatient and post-hospital opioid prescription practices following MIPRE. METHODS: A retrospective review at a single pediatric center was conducted of patients ≤21 years old who underwent MIRPE. Oral morphine equivalents (OME) of inpatient and discharge opioids were compared between Cryo and no-Cryo cohorts. RESULTS: 579 patients were identified (82.8% male, mean age 15.4 ± 2.0 years). Cryo was performed in 73.5% of patients. The total inpatient OME use was less in the Cryo group (0.89 ± 0.68 vs. 1.6 ± 0.5 OME/kg/day; p < 0.001). Patients who underwent Cryo were prescribed significantly less OME at discharge compared to the no-Cryo group (3.9 ± 1.7 vs. 10.0 ± 4.1 OME mg/kg, p < 0.001). There was no statistically significant difference in the proportion of patients who required an opioid prescription refill (Cryo 12.4% vs. no-Cryo 11.5%, p = 0.884) or were readmitted (Cryo 5.3% vs. no-Cryo 4.6%, p = 0.833). CONCLUSION: Patients who underwent cryoablation during MIRPE were prescribed significantly less opioid at the time of discharge without increasing the need for opioid refills or hospital readmissions. LEVEL OF EVIDENCE: Treatment study; Level III evidence.

OBJECTIVES: The Haller index (HI) is widely utilized as a quantitative indicator to assess the extent of the pectus excavatum (PE) deformity, which is the most common chest wall abnormality in children. Both preoperative correction planning and postoperative follow-up need to be based on the standard of normal thoracic growth and development. However, there is currently no established reference range for the HI in children. Consequently, the goal of this study was to conduct a preliminary investigation of normal HI values among children to understand thoracic developmental characteristics. METHODS: Chest computed tomography images obtained from January 2012 to March 2022 were randomly selected from the imaging system of the Children's Hospital of Chongqing Medical University. We divided the images of children into a total of 19 groups: aged 0-3 months (1 group), 4-12 months (1 group) and 1 year to 17 years (17 groups), with 50 males and 50 females, totaling 100 children in each group. HI was measured in the plane where the lowest point of the anterior thoracic wall was located and statistically analysed using SPSS 26.0 software. RESULTS: A total of 1900 patients were included in the study. Our results showed that HI, transverse diameter and anterior-posterior diameter were positively correlated with age (P < 0.05). Using age as the independent variable and HI as the dependent variable, the best-fit regression equations were HI-male = 2.047 * Age0.054(R2 = 0.276, P<0.0001) and HI-female = 2.045 * Age0.067(R2 = 0.398, P<0.0001). Males had significantly larger thoracic diameters than females, and there was little difference in the HI between the 2 sexes. CONCLUSIONS: The HI rapidly increases during the neonatal period, slowly increases during infancy and stops increasing during puberty, with no significant differences between the sexes.

OBJECTIVE: The Nuss bar removal procedure may bring about different complications. Some are mild while others can be life-threatening. An adequate surgery setup and the fulfilment of some security steps may reduce their incidence. This study aims to analyze our experience with the complications that occurred during bar removal and our safety protocol for the prevention and management of these complications. MATERIALS AND METHODS: Observational cohort study from a retrospective chart review of all patients who underwent Nuss bar removal from November 2013 to March 2022 at a University hospital. Variables analyzed include patients' demographics; presence of comorbidities; time elapsed from bar placement to removal, and the occurrence of operative and postoperative complications. Study written under the 'PROCESS Guideline'. RESULTS: Fourty (40) patients were included in the study; 37 were male. One bar was removed in 17 patients and two in 22 patients. Median age at surgery: 17.5 years (Percentile 25-75%: 16.75-19.25). Time elapsed from placement to removal: 26 months (Percentile 25-75%: 23.75-30.25). Complications: 10 in 9 patients (22.5%); 6 Clavien-Dindo class I (67%); 2 class II (22%); 1 class IIIb, 1 class IV. The hemorrhagic complication motivated the development of a safety protocol to reduce incidence of complications. CONCLUSION: Nuss bar removal is a safe procedure with usually scant complications. Nonetheless, these may be serious sometimes. To prevent them, a protocol for a safe procedure is important.
OBJETIVO: La retirada de la barra de Nuss puede provocar diversas complicaciones, algunas leves y otras potencialmente mortales. Su incidencia puede verse reducida con una preparación quirúrgica adecuada y siguiendo ciertos pasos de seguridad. El presente estudio tiene por objeto analizar nuestra experiencia con las complicaciones acontecidas durante la retirada de la barra, así como nuestro protocolo de seguridad para la prevención y el manejo de dichas complicaciones. MATERIAL Y METODOS: Estudio de cohortes observacional llevado a cabo a partir del análisis retrospectivo de todos los pacientes sometidos a cirugía de retirada de barra de Nuss entre noviembre de 2013 y marzo de 2022 en un hospital universitario. Se analizaron las siguientes variables: demografía de los pacientes, presencia de comorbilidades, tiempo desde la colocación de la barra hasta su retirada, y complicaciones operatorias y postoperatorias. El estudio se realizó conforme a las directrices de la PROCESS Guideline. RESULTADOS: Se incluyó a 40 pacientes, 37 de ellos varones. En 17 pacientes se retiró una barra, y en 22, dos. La edad media en el momento de la cirugía fue de 17,5 años (percentil 25-75%: 16,75 - 19,25). El tiempo transcurrido desde la colocación hasta la retirada fue de 26 meses (percentil 25-75%: 23,75 - 30,25). Se registraron 10 complicaciones en 9 pacientes (22,5%), 6 de clase I según la clasificación de Clavien-Dindo (67%), 2 de clase II (22%), 1 de clase IIIb y 1 de clase IV. La complicación hemorrágica motivó la creación de un protocolo de seguridad para disminuir la incidencia de las complicaciones. CONCLUSION: La retirada de la barra de Nuss es un procedimiento seguro, habitualmente con escasas complicaciones, aunque en ocasiones pueden ser graves. Para evitarlas, es importante contar con un protocolo que garantice la seguridad.

BACKGROUND: Usually, pectus bars are removed 3 years after the Nuss procedure in patients with pectus excavatum. However, the optimal timing for postoperative pectus bar removal remains undefined. Our study investigated the effects of delayed pectus bar removal after Nuss repairs. METHODS: Retrospective data were collected on patients who underwent Nuss procedures for pectus excavatum and had their bars removed from August 2014 to December 2020. Patients with correction periods > 3 years were divided into group A (< 6 years) and group B (≥ 6 years). Propensity score matching was used to compare complications and radiological outcomes associated with bar removal. RESULTS: Of the 542 patients who underwent bar removal, 451 (Group A: 419 patients, Group B: 32) had correction duration > 3 years. The average correction duration was 4.5 ± 1.4 years. After propensity score matching analysis, group B [median duration: 8.0 (6.0-16.2) years] exhibited significantly longer median operative times (85 vs. 55 min; P = 0.026), higher callus formation rates (68.8% vs. 46.9%; P = 0.029), and greater median intraoperative blood loss (35 vs. 10 mL; P = 0.017) than group A [median duration: 4.2 (3.0-5.9) years]. However, following bar removal, the groups showed no statistical differences in the surgical complication rates (group A: 6.3% vs. group B: 9.4%; P = 0.648) or median ratio of radiological improvement (an improvement on the Haller index on chest radiography; 21.0% vs. 22.2%; P = 0.308). CONCLUSIONS: Delaying pectus bar removal after Nuss repair presents certain challenges but does not compromise overall outcomes. These findings suggest that a longer correction period may be unnecessary. However, further multicenter studies with long-term follow-up are warranted to assess long-term outcomes.
