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.

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.

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.

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.

INTRODUCTION: Epidural 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 ANALYSIS: This 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 DISSEMINATION: This 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 NUMBER: NCT05731973.

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.

Limited data are available on the implications on pregnancy following pectus bar implantation for correction of pectus excavatum (Nuss procedure), while the pectus bars are in place. Limited data is also available on long-term reproductive implications following pectus bar removal.Providers at times need to consider the necessity to counsel a woman desiring pectus excavatum correction and pregnancy whether to postpone one of the two in favour of the other.We present the case of a woman of reproductive age with an uneventful pregnancy and delivery while carrying an implanted pectus bar and subsequent uneventful pregnancy and delivery after bar removal.

PURPOSE: Pectus excavatum (Pectus) repair may be offered for those with significant cardiopulmonary compromise or severe cosmetic defects. The influence of hospital center volume on postoperative outcomes in children is unknown. This study aimed to investigate the outcomes of children undergoing Pectus repair, stratified by hospital surgical volume. METHODS: The Nationwide Readmission Database was queried (2016-2020) for patients with Pectus (Q67.6). Patients were stratified into those who received repair at high-volume centers (HVCs; ≥20 repairs annually) versus low-volume centers (LVCs; <20 repairs annually). Demographics and outcomes were analyzed using standard statistical tests. RESULTS: A total of 9414 patients with Pectus underwent repair during the study period, with 69% treated at HVCs and 31% at LVCs. Patients at LVCs experienced higher rates of complications during index admission, including pneumothorax (23% vs. 15%), chest tube placement (5% vs. 2%), and overall perioperative complications (28% vs. 24%) compared to those treated at HVCs, all p < 0.001. Patients treated at LVCs had higher readmission rates within 30 days (3.8% vs. 2.8% HVCs) and overall readmission (6.8% vs. 4.7% HVCs), both p < 0.010. Among readmitted patients (n = 547), the most frequent complications during readmission for those initially treated at LVCs included pneumothorax/hemothorax (21% vs. 8%), bar dislodgment (21% vs. 12%), and electrolyte disorders (15% vs. 9%) compared to those treated at HVCs. CONCLUSION: Pediatric Pectus repair performed at high-volume centers was associated with fewer index complications and readmissions compared to lower-volume centers. Patients and surgeons should consider this hospital volume-outcome relationship. TYPE OF STUDY: Retrospective Comparative. LEVEL OF EVIDENCE: III.

BACKGROUND: Pectus excavatum (PE) is the most common congenital abnormality of the chest wall. Most patients with PE have slim bodies. Some studies have been conducted on the physical growth of children and adolescents who underwent the Nuss procedure. This study aimed to evaluate body measurement changes in adult patients with PE after the Nuss procedure. METHODS: A total of 272 adult PE patients, who underwent the Nuss procedure and pectus bars removal from August 2014 to December 2020, were evaluated retrospectively. Body measurement [body height (BH), body weight (BW), and body mass index (BMI)] of the patients were collected before Nuss repair and after bar removal. We used the interquartile range (IQR) to identify and exclude outliers. Associations between changes in body measurement and clinical and radiological features were evaluated. RESULTS: The BH, BW and BMI showed significantly increased after pectus bar removal, compared to pre-Nuss procedure parameters (BH 173.8 ± 5.9 cm vs. 173.9 ± 5.9 cm, P < 0.001; BW 60.3 ± 8.1 kg vs. 61.1 ± 8.8 kg, P = 0.005; BMI 19.9 ± 2.2 kg/m2 vs. 20.1 ± 2.4 kg/m2, P = 0.02). The same result were observed in the male subgroup, the HI ≥ 4 group and the male subgroup within the HI ≥ 4 group. CONCLUSIONS: The BH, BW and BMI were significantly increased after completing surgical correction of PE using the Nuss procedure, particularly in young males and patients with more pronounced deformities.

Surgical treatment of the pectus excavatum has led to the introduction of the Nuss procedure, a minimally invasive surgical procedure that involves inserting a metal bar under the sternum through a small lateral thoracic incision. An additional metal bar was inserted in patients with pectus excavatum to improve the retention of the restored chest wall after the Nuss procedure. However, a need still exists to analyze the mechanistic advantages and disadvantages of the double-bar method owing to the increased surgical time and proficiency. The purpose of this study is to compare and evaluate the efficiency of single- and double-bar methods using rotational and equilibrium displacement simulations of the Nuss procedure. A finite-element model was constructed for two types of metal bars inserted into the chest wall. Boundary conditions for the rotation and equilibrium displacements were set for the metal bar. The anterior sternal translation, Haller index and maximum equivalent stress and strain owing to the behavior of the metal bar were estimated and compared with the single-bar method and postoperatively acquired patient data. The simulation results showed that the influences of the intercostal muscle and equilibrium after rotation displacement were significant. The stresses and strains were distributed across the two metal bars, and the upper-metal bar was heavily loaded. The double-bar method was advantageous regarding the load distribution effects of the two metal bars on the chest wall. However, mechanical assessments are also important because an excessive load is typically applied to the upper-metal bar.

Pectus excavatum is a common chest wall deformity, most often treated during adolescence, that presents a significant postoperative pain control challenge for pediatric surgeons following surgical correction. The purpose of this article is to review the technique and outcomes of intercostal spinal nerve cryoablation for postoperative analgesia following surgical correction of pectus excavatum. Contemporary and historic literature were reviewed. Findings are summarized to provide a concise synopsis of the benefits of intercostal spinal nerve cryoablation relative to alternative analgesic modalities, as well as advocate for more widespread inclusion of this technique into multimodal pain regimens.

BACKGROUND: We aimed to assess the effectiveness of the Nuss procedure for pectus excavatum (PE) and explore the impacts of sex and age on outcomes. METHODS: We retrospectively reviewed 594 consecutive children ≤18 years of age who underwent the thoracoscopy-assisted Nuss technique between January 2006 and July 2019. The severity of pectus deformity was calculated according to the Haller index (HI). The classification of PE and clinical data including complications was analyzed. RESULTS: Of the 594 patients, 456 (76.8%) were boys and 138 (23.2%) were girls. The mean age at surgery was 10.0 ± 5.0 years. The most common types of PE were 1A and 2A2 according to Park classification. Intraoperative and postoperative complication rates were 2/594 (0.3%) and 74/594 (12.5%), respectively. The most common complication was bar displacement. The bar was removed in 414 patients 3.5 ± 0.8 years later. The mean preoperative HI, postoperative HI with bar, and HI after bar removal were 4.2 ± 1.7, 2.4 ± 0.3, and 2.7 ± 0.5, respectively. Compared to the preoperative HI, both the postoperative HI with bar and HI after bar removal were significantly lower ( p < 0.001). For preschool-age children, the preoperative HI was significantly higher ( p = 0.027) and the change in HI significantly improved compared to school-age children ( p = 0.004). Boys and adolescents needed significantly more bars and stabilizers. CONCLUSION: Surgical correction of PE using the Nuss procedure is a safe procedure and improves the HI in children of different ages, even in those younger than 6 years of age.

PURPOSE: The most recent procedure for pectus excavatum repair involves crane-powered entire chest wall remodeling, which employs crane lifting, multiple-bar approach, bridge stabilization, and sandwich techniques. This resulted in a paradigm shift in pectus deformity repair from merely lifting the sunken bone to remodeling the chest wall into normal anatomy. METHODS: We analyzed 649 patients who underwent surgery for pectus excavatum or complex combined deformities between March 2018 and January 2022. A crane with sternal wiring or screwing was used to lift the chest wall without using the pectus bar turning power. Multiple bars with bridge connections were placed to eliminate bar displacement. Modified sandwich techniques were applied to relieve the lower coastal flare (flare-buster) and focal protuberance (magic string). RESULTS: The mean age of the patients included in the study was 12.2 years (range: 3-45 years). A single bar was used for 202 patients until 2021. For the multiple-bar technique, parallel bars (n = 142), crossbars (n = 166), and crossbars plus upper horizontal bars (XI pattern; n = 139) were used. The overall complication rate was 6.2 %. There was no cases of bar displacement were observed, but other minor complications such as pneumothorax (n = 20, 3.1 %), pleural effusion (n = 7, 1.1 %), and wound infection (n = 5, 0.8 %) were detected. Three patients required reoperation (infection, two: hemorrhage, one). CONCLUSIONS: The crane-powered entire chest wall remodeling technique improved the safety and comprehensiveness of the repair procedure. By incorporating bridge stabilization and the use of multiple bars, we effectively resolved the issues related to bar displacement and incomplete repair. TYPE OF STUDY: Retrospective Cohort Study.

Since the 1970s, magnets have been progressively harnessed for use in minimally invasive treatment of pediatric surgical disease. In particular, multiple magnetic devices have been developed for treating esophageal atresia, pectus excavatum and scoliosis. These devices, which can be placed via small incisions or under endoscopic or fluoroscopic guidance, provide the added benefit of sparing patients multiple large, invasive procedures, and allowing for gradual correction of congenital anomalies over days to months, depending on the disease. In the following text, we detail the current landscape of magnetic devices used by pediatric surgeons, illustrate their use through clinical cases, and review the available body of literature with respect their outcomes and complications.

BACKGROUND: Pectus excavatum repair is associated with significant discomfort, and pain is a primary contributor to postoperative hospital length of stay. Recent advances in postoperative pain control include the use of intercostal cryoablation techniques that may now make it possible to discharge patients on the day of surgery. Unnecessary variation in patient care and noncompliance with care bundles may be a factor in extended length of stay. The global aim of this quality improvement initiative was to successfully implement an enhanced recovery after surgery (ERAS) pathway on patients undergoing pectus excavatum repair. The SMART aim was to have a greater than 70% compliance for the perioperative bundle elements within 1 year of the pathway implementation. METHODS: Multiple Plan-Do-Study-Act (PDSA) cycles were designed to create and implement an ERAS pathway for patients undergoing a pectus bar insertion procedure. This multidisciplinary pathway was designed, managed, and implemented with key stakeholders from the Departments of Evidence Based Practice, Surgery, Anesthesiology, and Perioperative Nursing. Patient characteristics, outcomes, and compliance with elements of the pathway were measured for analysis for both the baseline and post-intervention groups with monthly automated reports. RESULTS: After implementation of the ERAS pathway, data on the first 50 patients showed a 90% compliance with the perioperative bundle elements. Mean length of stay was significantly decreased from 33 h (95% CI [28.76, 37.31]) to 18 h (95% CI [14.54, 21.70]). There were zero readmissions within 24 hours for patients who were discharged on the day of surgery. CONCLUSION: Employing a multidisciplinary approach in both planning and execution that standardized clinician practices and minimized unnecessary variation in patient care, an ERAS pathway for pectus bar insertion has been successfully established at our institution.

Pectus excavatum is the most encountered of chest wall deformities. It may produce respiratory and cardiovascular symptoms, hence surgical repair of this defect is performed. The procedure involving the insertion of metal bars under the sternum (the Nuss procedure) usually brings significant improvement to patients. However, the effect of the repair on the postural stability of patients has not been studied so far. To investigate the problem of patients' stability in the postoperative period male patients with pectus excavatum (n = 21) and healthy controls (n = 22) were included in the study. Using posturography methods, we showed a negative impact of the pectus excavatum repair surgery on patients' postural stability in the first postoperative phase. The centre of pressure displacement parameters used to measure postural stability were lower after the repair for both, the frontal and sagittal plane as well as for the velocity of displacements in the sagittal plane in the double stance with eyes open. Poorer postural stability was also found in patients with pectus excavatum when compared to healthy controls. Our findings may be useful for functional monitoring in the evaluation and surgical management of pectus excavatum patients and also when designing the rehabilitation of patients undergoing the Nuss procedure.

Chest wall deformities in children encompass a broad spectrum of disorders but pectus excavatum and carinatum are by far the most common. Treatment varies substantially by center, and depends on patient symptoms, severity of disease, and surgeon preference. Historically, surgical approaches were the mainstay of treatment for these disease processes but new advances in non-surgical approaches have demonstrated reasonable results in select patients. These non-surgical approaches include vacuum bell therapy, autologous fat grafting and hyaluronic acid injections for pectus excavatum, and orthotic brace therapy for pectus carinatum. There is debate with regards to optimal patient selection for these non-surgical approaches, as well as other barriers including reimbursement issues. This paper will review the current non-surgical approaches to chest wall deformities available, including optimal patient selection, treatment protocols, indications, contraindications, and outcomes.

BACKGROUND: Pectus excavatum (PE) is the most common congenital chest wall deformity, whose cardiopulmonary consequences are controversial. PE surgery is in our experience usually performed for aesthetic reasons. OBJECTIVES: The aim of this study was to evaluate the impact of PE on respiratory function and exercise capacity in patients with PE before patient-specific silicone implant correction. METHODS: This monocentric prospective study conducted at Toulouse University Hospital included sixty patients scheduled for custom-made silicone implants correction. Respiratory function (pulmonary function tests (FPTs)) and exercise capacity (VO2 max) were measured before surgery. RESULTS: Before surgery, no (0/60) restrictive lung disease was detected, with a mean total lung capacity (TLC) of 98.5% of predicted value (IC 95%; 80.4-137). Median VO2 max (n=56) was normal (89% predicted), with no cardiac limitation. CONCLUSION: In this cohort, PE had no impact on respiratory function nor exercise capacity. In patients without cardiac or respiratory effects of PE, silicone implants should be considered the preferred approach as it adequately addressed patients' main complaint of low self-esteem.
