Abstract
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.

Abstract
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.

Abstract
Background Chest wall re-depression after bar removal (BR) in pectus excavatum (PE) is insufficiently investigated. However, it is not easy to investigate chest wall re-depression due to its multifactorial characteristics. Herein, we investigated chest wall re-depression after BR using machine learning algorithms. To the best of my knowledge, this is the first study of chest wall re-depression after BR using machine learning algorithms. Methods We retrospectively reviewed 199 consecutive subjects who underwent both minimally invasive repair of pectus excavatum (MIRPE) and BR at a single hospital from March 2012 to June 2020. We investigated attributes of chest wall re-depression and risk factors for recurrence after BR, predicted final degree and recurrence of PE after BR, and suggested the optimal age at the time of MIRPE based on recurrence. Data for the chest wall re-depression were analyzed to discover differences according to age group [<10 years (early repair group; EG) vs. ≥10 years (late repair group; LG)]. Results We observed no significant difference between the Haller index and radiographical pectus index (RPI) (P=0.431) and a significant correlation between Haller index and RPI (P<0.001). RPI significantly increased for the first 6 months after BR in both age groups (both P<0.001) and was maintained at 1 year after BR. RPI value of the LG were significantly higher than those of the EG for the entire period after MIRPE (P=0.041). Recurrence of PE in the LG was significantly more frequent than in the EG (P<0.001). RPI values before and after MIRPE and age group were identified as independent risk factors for recurrence after BR (P<0.001, P=0.007, and P=0.001, respectively). The linear regression model outperformed for final RPI with performance scores of mean squared error 0.198, root mean squared error 0.445, mean absolute error 0.336, and R2 0.415. In addition, the logistic regression model outperformed for predicting recurrence with performance scores of 0.865 the area under the curve, 0.884 accuracy, 0.859 F1, 0.865 precision, and 0.884 recall. Conclusions The present study shows that machine learning algorithms can provide good estimates for postoperative results in PE. An approach integrating machine learning models and readily available clinical data can be used to create other models in the thoracic surgery field.

Abstract
BACKGROUND Our study aimed to compare the prevalence of postoperative fever during the COVID-19 pandemic period with that of the preceding non-pandemic period. METHODS A retrospective analysis was conducted on patients with pectus excavatum (PE) undergoing minimally invasive repair (also called NUSS procedure) at Nanjing Children's Hospital from January 1, 2017 to March 1, 2019 (Group 2019), and from January 1, 2020 to March 1, 2021 (Group 2021). Data from a total of 284 patients, consisting of 200 (70.4%) males and 84 (29.6%) females with an average age of 9.73 ± 3.41 (range, 4 to 17) years, were collected. The presence of post-operative fever (defined as a forehead temperature of 37.5℃ or above within 72 h post-surgery), as well as the time of operation, duration of postoperative mechanical ventilator and urinary catheter use, and length of hospitalization were all assessed in admitted patients from Group 2019 (n = 144) and Group 2021 (n = 140). Postoperative white blood cell (WBC), C-reactive protein (CRP) levels, and prevalence of postoperative complications (i.e., pneumothorax, pulmonary atelectasis, pneumonia, wound infection, and dehiscence) were also determined. RESULT Our results showed a statistically significant decrease in the incidence of postoperative fever within 24 to 72 h of surgery in patients admitted from Group 2019 as compared to Group 2021 (p < 0.001), as well as a decrease in peak body temperature within 72 h (p < 0.05). Meanwhile, no significant differences were observed in age and body mass index (BMI), time of operation, or duration of postoperative mechanical ventilator and urinary catheter use between the two groups (p > 0.05). The average hospitalization length of Group 2021 was significantly shorter than Group 2019 (12.49 ± 2.57 vs. 11.85 ± 2.19 days, p < 0.05). Furthermore, while the WBC count between the two groups 24 h after surgery showed a statistical difference (p < 0.05), no differences in CRP levels or the incidence of postoperative complications were observed (p > 0.05). CONCLUSION The prevalence of postoperative fever within 72 h of surgery and the length of hospital stay for patients with PE undergoing NUSS surgery were both decreased in Group 2021. We propose that the above phenomenon may be related to increased used of personal protection equipment (such as surgical masks and filtering facepiece respirators (FFRs)) by physicians, nurses, and the patients themselves.

A Novel Method of Minimally Invasive Repair of Pectus Excavatum (MIRPE) in Patients with Bilateral Breast Prostheses: a Report of Two Patients. Indian J Surg 2022.

Abstract
Abstract The literature on minimally invasive repair of pectus excavatum in patients with breast prostheses is very scarce, with only one report to date. We present two cases treated in our center in which this technique was performed without prior removal of the breast prostheses. In one of the patients, a sternal zenithal traction system was additionally used to facilitate retrosternal dissection. In this work, we present the technical details of the procedure. One of the patients presented with postoperative Dressler’s syndrome which resolved with conservative measures. We found no correlation between this complication and the presence of breast prostheses. After 4 and 2 years respectively, both patients are asymptomatic, with an adequate correction of the defect, and being followed up. Minimally invasive repair of pectus excavatum technique is safe and feasible in patients with bilateral breast prostheses. The placement of breast prostheses prior to the correction of rib cage deformities leads to an unpredictable aesthetic result in certain aspects, such as the exact positioning of the nipple areola complex. The approach to this pathology by a pediatric surgeon, who considers not only the aesthetic aspect but also the rib cage involvement and the potential presence of additional malformations (for example, a Poland sequence), is, in the authors’ opinion, beneficial to the overall outcome of these patients.

Abstract
INTRODUCTION The surgical Nuss correction of the funnel chest deformity is a painful procedure without an established consensus of pain relief methods. High doses and long duration of opioids requirements impedes the ERAS protocol introduction. The aim of this study was to evaluate the effectiveness of intraoperative intercostal nerve cryolysis in terms of pain management in relation to the routinely used multimodal analgesia in Poland. We also assessed the impact of using the proprietary "BackOnFeet" application on the quality of life of patients after surgery in relation to the ERAS protocol. METHODS The prospective, single-centre, non-randomised, before-after pilot study was conducted. Inclusion criteria were: funnel-shaped chest deformity, age range 11-18 years, first chest wall operation, agreement for the cryolysis and regional analgesia, no history of chronic painkillers use. The results of the "control group" (multimodal analgesia with regional analgesia commonly performed in Poland) were assessed. The interdisciplinary perioperative protocol with the "BackOnFeet" application and intraoperative intercostal nerve cryoanalgesia were introduced to the "intervention group". RESULTS Eighteen children were treated with standard protocol typical for Polish management and matched to eighteen patients who received cryoanalgesia and the "BackOnFeet" application access "intervention group". We noticed lower NRS points in first 24 h (p = 0.0048), shortening of time of opioid use (p = 0.0002), hospitalisation time (p = 0,01), improved quality of postoperative rehabilitation (p < 0.0001) and quality of life (p < 0.0001) among the "intervention group". CONCLUSIONS Intraoperative intercostal nerves cryolysis performed during the minimally invasive Nuss correction of funnel deformation in combination with bilateral is more effective in terms of acute pain management in relation to the routinely used multimodal analgesia in Poland, allowing for the shortening of time of opioid use, hospitalisation time, improved quality of postoperative rehabilitation and enabled ERAS protocol introduction. The use of the proprietary "BackOnFeet" application has a positive effect on the quality of life of patients after surgery.
