Abstract
Congenital heart disease may present with pectus excavatum. Concomitant and staged repair are described, but the optimal approach is controversial. We report a 17-year-old male with left aortic arch, aberrant right subclavian artery, and Kommerell diverticulum who presented with long standing swallowing difficulties, prandial nausea, and pectus excavatum with cosmetic concerns. Kommerell diverticulectomy, carotid-subclavian bypass, and modified Ravitch pectus excavatum repair were performed without complication. Concomitant congenital heart surgery and pectus excavatum repair may be successfully performed in a single operation via sternotomy. Incidence, operative approaches, and complications of concomitant versus staged correction of congenital heart disease and pectus excavatum are briefly reviewed.

Goel A, Goel A. Optimal timing for plastic surgical procedures for common congenital anomalies: A review. World J Clin Pediatr 2024; 13:90583. [PMID: 38947997 PMCID: PMC11212758 DOI: 10.5409/wjcp.v13.i2.90583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 04/04/2024] [Accepted: 04/11/2024] [Indexed: 06/07/2024] Open
Abstract
Apart from listening to the cry of a healthy newborn, it is the declaration by the attending paediatrician in the labour room that the child is normal which brings utmost joy to parents. The global incidence of children born with congenital anomalies has been reported to be 3%-6% with more than 90% of these occurring in low- and middle-income group countries. The exact percentages/total numbers of children requiring surgical treatment cannot be estimated for several reasons. These children are operated under several surgical disciplines, viz, paediatric-, plastic reconstructive, neuro-, cardiothoracic-, orthopaedic surgery etc. These conditions may be life-threatening, e.g., trachea-oesophageal fistula, critical pulmonary stenosis, etc. and require immediate surgical intervention. Some, e.g., hydrocephalus, may need intervention as soon as the patient is fit for surgery. Some, e.g., patent ductus arteriosus need 'wait and watch' policy up to a certain age in the hope of spontaneous recovery. Another extremely important category is that of patients where the operative intervention is done based on their age. Almost all the congenital anomalies coming under care of a plastic surgeon are operated as elective surgery (many as multiple stages of correction) at appropriate ages. There are advantages and disadvantages of intervention at different ages. In this article, we present a review of optimal timings, along with reasoning, for surgery of many of the common congenital anomalies which are treated by plastic surgeons. Obstetricians, paediatricians and general practitioners/family physicians, who most often are the first ones to come across such children, must know to guide the parents appropriately and convincingly impress upon the them as to why their child should not be operated immediately and also the consequences of too soon or too late.

Fenikowski D, Tomaszek L. Factors Related to Anxiety in Paediatric Patients and Their Parents before and after a Modified Ravitch Procedure-A Single-Centre Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16701. [PMID: 36554581 PMCID: PMC9779648 DOI: 10.3390/ijerph192416701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 12/08/2022] [Accepted: 12/10/2022] [Indexed: 06/17/2023]
Abstract
OBJECTIVE To assess the factors related to perioperative state anxiety in paediatric patients and their parents. METHODS A cohort study was conducted on paediatric patients 9-17 years of age, who underwent the modified Ravitch procedure (n = 96), and their parents (n = 96). The level of anxiety was measured using the State-Trait Anxiety Inventory questionnaire. Multivariable linear regression models were calculated to find the relationships between the pre- and postoperative state anxiety of the patients/parents and the independent variables, both demographic (age, gender) and clinical (e.g., postoperative pain, trait anxiety). RESULTS Preoperative anxiety in the paediatric patients was positively correlated with their trait anxiety (β = 0.47; 95% CI: 0.29 to 0.64) and preoperative parental anxiety (β = 0.24; 95% CI: 0.07 to 0.42). The high level of preoperative anxiety (vs. low and moderate) (β = 0.40; 95% CI: 0.22 to 0.58), trait anxiety (β = 0.22; 95% CI: 0.04 to 0.40) and average postoperative pain at rest (β = 0.18; 95% CI: 0.01 to 0.34) had a positive impact on the postoperative anxiety in patients. However, the patients' age was negatively correlated with postoperative anxiety (β = -0.19; 95% CI: -0.35 to -0.02). Three variables were found to predict preoperative parental anxiety: their trait anxiety (β = 0.41; 95% CI: 0.23 to 0.59), female gender (β = 0.18; 95% CI: 0.002 to 0.36) and the intravenous route for the postoperative pain management in the patients (β = -0.18; 95% CI: -0.36 to -0.001). The parental postoperative anxiety was influenced by their trait anxiety (β = 0.24; 95% CI: 0.04 to 0.43), preoperative anxiety in patients (β = 0.21; 95% CI: 0.02 to 0.40) and female gender of children (β = 0.19; 95% CI: 0.001 to 0.39). CONCLUSIONS Trait anxiety was a strong factor positively affecting the perioperative state anxiety. In addition, paediatric patient anxiety before surgery was related to their parents' anxiety, and, after surgery, this was associated with high preoperative anxiety, pain and age. The parents' anxiety before surgery was influenced by gender and the type of postoperative analgesia in the patients, while, after surgery, this was influenced by the patients' preoperative anxiety/gender.

Abstract
The authors present a new study on 789 cases of congenital thoracic malformations including 638 pectus excavatum and 151 Poland syndromes, according to a new classification which completes Chin's one. All these malformations were treated with silicone elastomer implants. The contribution of computer-aided design and manufacturing (CAD/CAM) since 2008 is essential. The one-stage surgical protocol is precisely described. The results are impressive, permanent, for life, and complications are rare. The authors evoke a common vascular etiopathogenesis theory at the embryonic stage and question the heavy techniques of invasive remodeling that are most often unjustified.

Abstract
Most common congenital malformation of the thorax, Pectus Excavatum affects about one in 500 people. Several surgical or medical techniques have been proposed. Some are followed by complications or insufficient results even though their constant functional value is highly controversial. Secondary surgery with a deep customized 3D elastomer implant, may be an elegant effective and safe solution compared to others; it allows a good aesthetic result expected by patients in the absence of any respiratory or cardio-vascular functional context.

Abstract
BACKGROUND Wound healing problem is one of the main complications after correction of chest wall deformity. Orthopedic flap tissue repair technique has a clear significance in non-healing wound and defect wound and provides a new choice for poor wound healing after orthopedic surgery of chest wall deformity. OBJECTIVE To investigate, the application value of modified local rotary flap and latissimus dorsi myocutcutaneous flap in the treatment of poor wound healing after orthodontic treatment of chest wall deformity. METHOD A retrospective analysis was performed on patients who admitted to our department from August 2012 to November 2019 due to non-healing incision after surgery for thoracic deformity. Skin flap was selected according to the size of the wound surface, and the effect of skin flap repair was observed. The clinical data of the included patients were recorded, and the preoperative and postoperative wound conditions were evaluated. RESULTS This study included 13 patients with chest wall deformity who received plastic surgery tissue using flap technique for wound repair, 11 cases used modified local rotation skin flap, and 2 cases used modified latissimus dorsi myocutaneous flap. The mean age of the 13 patients was 18.54 ± 4.14 years old, the mean body mass index (BMI) was 17.02 ± 2.16 kg/m2 , and the mean preoperative nonunion time of the incision was 64.77 ± 93.01 days. Five patients had positive bacteria culture on the wound surface, including 3 cases of Staphylococcus aureus, 1 case of Pseudomonas aeruginosa, and 1 case of Staphylococcus epidermidis. All the 13 patients achieved primary grade A healing. CONCLUSION The modified local rotary flap and latissimus dorsi musculocutaneous flap have a significant effect on the postoperative correction of chest wall deformity, which can ensure wound healing while retaining the orthopedic plate to the maximum extent to ensure the effect of the correction.

Abstract
BACKGROUND Pectus excavatum (PE) is the most common congenital chest wall deformity. Most individuals with PE suffer from psychosocial problems, with low self-esteem and poor body image. Correctional surgery for PE is available, the most widely used is the Nuss procedure. The Nuss procedure has previously been reported to improve self-esteem, body image and health-related quality of life (HRQoL). To assess HRQoL among individuals with PE, the Nuss Questionnaire modified for Adults (NQ-mA) and Single Step Questionnaire (SSQ) has been developed. The aim of the current study was to translate and culturally adapt NQ-mA and SSQ to fit a Swedish context, and to evaluate the psychometric properties, and validate the culturally adapted versions. METHODS Individuals who had undergone the Nuss procedure for pectus excavatum were invited to participate in a multicentre study with cross-sectional design. HRQoL was assessed by NQ-mA, SSQ and RAND-36. Psychometric properties for NQ-mA and SSQ were evaluated by content validity index and construct validity (exploratory factor analysis, confirmatory factor analysis, and inter-scale correlations). Known-groups validity, as well as floor and ceiling effects, were evaluated. Internal consistency reliability was examined using Cronbach's alpha. RESULTS In total 236 individuals participated in the study. Content validity index for NQ-mA showed satisfactory results, except for two items. Factor analysis for NQ-mA suggested a two-factor model, with exclusion of two items. Subscales correlated adequately with RAND-36's domains. Known-groups validity for NQ-mA demonstrated high sensitivity for between-group differences. Ceiling effects were present in several items. Cronbach's alpha for NQ-mA was .89. Confirmatory factor analysis for SSQ resulted in a three-factor model, with exclusion of five items. However, this model was shown to be unstable through further exploratory factor analysis testing, and no further psychometric tests were conducted for SSQ. CONCLUSION The 10-item Swedish version of NQ-mA was shown to be valid for research and clinical assessment of HRQoL in individuals with pectus excavatum. The Swedish version of SSQ requires revision of items before further validation can be performed.

Abstract
Introduction: The anti-Nuss procedure has gradually been found to have several shortcomings in clinical practice. Accordingly, our department previously designed and introduced a new steel plate. However, there is limited evidence regarding its safety and efficacy. Thus, we aim to compare the efficacy and safety of the conventional anti-Nuss operation with those of a modified anti-Nuss operation using a flexible plate. Methods: Patients with pectus carinatum who underwent surgery between January 2014 and August 2019 were consecutively enrolled in this single-center, retrospective study. In all, 53 patients underwent the modified procedure using the new steel plate (new procedure group), whereas 43 underwent the conventional anti-Nuss procedure (traditional procedure group). Outcome analysis was performed using SPSS to compare the intraoperative and postoperative short-term outcomes. Results: All patients in the new procedure group had shorter operation duration (75.23 ± 11.90 vs. 82.45 ± 9.30 min, p = 0.008), postoperative hospitalizations (3.42 ± 0.95 vs. 4.64 ± 1.53 days, p = 0.039), and plate removal surgery durations (40.60 ± 3.47 vs. 60.30 ± 9.75 min, p = 0.041) than patients in the traditional procedure group. There were no significant differences in the length of incision, postoperative Haller index, cost, postoperative surgical outcome, and incidence of complications between the two groups. Conclusion: Our data reveal that the main clinical outcomes were similar for after anti-Nuss operation and modified anti-Nuss operation. However, the modified procedure for pectus carinatum had a shorter operation duration, postoperative hospitalization, and plate removal surgery duration.
