摘要
Pectus excavatum(PE) is a congenital chest deformity characterized by deep depression in the sternum. Autologous fat transplantation has been used for aesthetic purposes, mainly on the face, and has recently gained relevance in thoracic and breast surgeries. The present study aims to present a case of mild PE associated with hypomastia. A 24-year-old female patient attended the consultation for breast augmentation due to hypomastia, but the clinical examination also revealed an associated mild PE that the patient did not notice. Surgical planning included breast augmentation and autologous fat transfer. A 260ml silicone breast implant was used, and 250ml of fat was injected in the sternal region and the lower medial contour of the breasts. There were no complications during the 12-month follow-up period. The combination of augmentation mammoplasty and fat transplantation in treating PE deformity proved to be a minimally invasive, good, safe option with high patient satisfaction.
Pectus excavatum (PE) é uma deformidade torácica congênita, caracterizada como uma depressão profunda no esterno. O transplante autólogo de gordura tem sido utilizado para fins estéticos, principalmente na face, e recentemente ganhou relevância nas cirurgias torácica e das mamas. O objetivo do presente estudo é apresentar um caso de PE leve associado a hipomastia. Uma paciente de 24 anos compareceu à consulta para mamoplastia de aumento por hipomastia, mas o exame clínico também revelou um PE leve associado que não foi percebido pela paciente. O planejamento cirúrgico incluiu a mamoplastia de aumento e a transferência de gordura autóloga. Foi utilizado um implante mamário de silicone de 260ml, e uma quantidade total de 250ml de gordura foi injetada na região esternal e no contorno medial inferior das mamas. Não houve complicações durante o período de acompanhamento de 12 meses. A associação de mamoplastia de aumento e transplante de gordura no tratamento da deformidade de PE revelou-se uma opção minimamente invasiva, boa, segura e com alta satisfação da paciente.
摘要
El pectus excavatum (PEX) es una deformación de la pared torácica que obedece a una alteración de los cartílagos costales con el consiguiente hundimiento del esternón. Históricamente, se clasificaba como un defecto únicamente estético o cosmético, sin embargo, en los últimos años se han desarrollado nuevos métodos de estudio para la valoración de las repercusiones de esta patología. Existe cada vez más bibliografía que demuestra importantes repercusiones funcionales. Se realizó una puesta al día de las repercusiones cardíacas de la patología y un análisis de los artículos más relevantes de los últimos años. La evidencia actual permite afirmar que existe una afectación cardíaca por compresión esternal en la mayoría de los pacientes con PEX. Las afectaciones incluyen alteraciones anatomofuncionales (trastornos del ritmo, disminución del llenado ventricular), del volumen sistólico, aumento de la presión de la aurícula derecha, valvulopatías, compresión del ventrículo derecho, derrame pericárdico, entre otras. Todo lo cual permite concluir que el PEX puede presentar importantes alteraciones cardíacas que deben ser tenidas en cuenta a la hora de valorar los pacientes con esta patología.
Pectus excavatum (PEX) is a deformation of the chest wall caused by an alteration of the costal cartilages with the consequent collapse of the sternum. Historically, it had been classified as a solely aesthetic or cosmetic defect, however, in recent years new study methods have been developed to assess the repercussions of this pathology, with increasing bibliography showing important functional consequences. We updated the cardiac pathological repercussions and analyzed the most relevant articles of recent years. The current evidence suggests that there is cardiac involvement due to sternal compression in most patients with PEX. These affectations include anatomical functional alterations: rhythm disorders, decreased ventricular filling, decreased stroke volume, increased right atrial pressure, valve disease, right ventricular compression, pericardial effusion, among others. All of which enables us to conclude that PEX can present important cardiac alterations that must be taken into account when assessing patients with this pathology.

As evidências atuais permitem afirmar que há acometimento cardíaco por compressão esternal na maioria dos pacientes com PEX. As afecções incluem alterações anatomofuncionais: distúrbios do ritmo, diminuição do enchimento ventricular, diminuição do volume sistólico, aumento da pressão atrial direita, doença valvular, compressão do ventrículo direito, derrame pericárdico, entre outras. Tudo isso permite concluir que o PEX pode apresentar alterações cardíacas importantes que devem ser levadas em consideração na avaliação de pacientes com essa patologia.

Pectus excavatum (PEX) is a thoracic wall malformation due to an alteration of the costal cartilages with subsequent sinking of the sternum. Historically, it was considered a mere aesthetic or cosmetic defect, however, in recent years, new assessment methods have been developed to evaluate the repercussions of this pathology, and there is an increasing literature that demonstrates important functional consequences. We carried out an update of this pathology's pulmonary repercussions and analyzed the most relevant articles of the recent years. Respiratory symptoms are frequent, present in more than half of the patients. A decrease in FVC, FEV1 and PEF25%-75% has been shown; as well as the presence of a restrictive and/or obstructive pattern, an increase in RV and an alteration in respiratory dynamics. The affectation of PEX on pulmonary function has been objectified, and it has been determined categorically that this pathology has important functional consequences.

Objective:To investigate the effects of ultrasound-guided bilateral erector spinal plane nerve block on postoperative pain and sleep quality in children with pectus excavatum undergoing Nuss.Methods:From February 2020 to December 2021, 40 children with pectus excavatum undergoing Nuss from Hunan Children′s Hospital were prospectively selected and randomly divided into two groups: group E (group E) with erector spinal muscle plane block combined with general anesthesia and group G (group G) , with 20 patients in each group. After general anesthesia, ultrasound guided plane nerve block of bilateral erector spinal muscles was performed in group E, and general anesthesia with tracheal intubation was performed in group G. The Visual Analogue Scale (VAS) Score were recorded at 2, 6, 12, 24 and 48 hours after surgery; The addition of sufentanil, the time of extubation of post anesthesia recovery room (PACU) and the time of leaving the PACU in each group were recorded; The effective pressure times of analgesic pump and the number of people for remedial analgesia were recorded. Pittsburgh sleep quality index (PSQI) was used to score the sleep quality of children before and 2 days after surgery. The occurrence of hypoxemia and restlessness after extubation, nausea and vomiting, pneumothorax, local anesthetic poisoning and other complications were recorded.Results:The VAS score of group E at 2, 6, 12 and 24 hours after operation was lower than that of group G (all P<0.05). There was no significant difference in VAS score 48 hours after operation between the two groups ( P>0.05). The time of decannulation and recovery of PACU in group E was shorter than that in group G (all P<0.05). Compared with group G, there were fewer cases of sufentanil added in group E during operation, and the number of analgesia pump pressing times and cases of postoperative remedial analgesia in group E were less than those in group G (all P<0.05). The PSQI score of sleep quality index 2 days after operation in group E was better than that in group G ( P<0.05). The incidence of hypoxemia, restlessness, nausea and vomiting in group E was lower than that in group G (all P<0.05). Conclusions:Ultrasound-guided bilateral erector spinal nerve block can effectively reduce postoperative pain and complications of NUSS in children with pectus excavatum, and can also reduce the amount of sufentanil used during the operation, improve the sleep quality after the operation, which is conducive to the recovery of children, and is worthy of promotion.

ABSTRACT Objective: This study aims the treatment results of broad pectus excavatum after a long-term follow-up and skeletal maturity. Methods: Eighty-four children and adolescents with broad-type pectus excavatum were selected for evaluation after treatment with a dynamic orthosis that applies compression to the lower rib projections and prescription of exercises. The broad pectus excavatum was defined as a deformity that the depressed area was greater and covered the area above and below the nipple line. All patients were evaluated for more than 1 year after the end of treatment and skeletal maturity. Post-treatment results were categorized as mild, moderate and severe. Statistic correlations between results and deformity flexibility, deformity severity, and adherence to treatment were assessed. Results: The mean age at the beginning of treatment was 13.3 years, and the follow-up duration was 25.7 months after suspension of orthosis use. Forty-eight percent of patients showed good results. With regular use of orthoses and performance of exercises, this rate increased to 70% (p < 0,001). Mild cases showed more success than severe cases (p = 0,007). Initial flexibility didn't influence the results (p = 0,63). Conclusion: Treatment of broad pectus excavatum with orthoses and exercises led to good definitive results in most resilient patients, especially in those with mild deformities. Level of Evidence V, Expert Opinion.
RESUMO Objetivo: Estudar os resultados de longo prazo e com seguimento até a maturidade esquelética do tratamento do pectus excavatum amplo. Métodos: 84 crianças e adolescentes foram tratados com uma órtese que aplicacompressão nas saliências costais inferiores, associada a exercícios específicos. A deformidade foi classificada como ampla quando a depressão tem maior extensão e abrange uma área acima e abaixo da linha mamilar. Os resultados foram categorizados em ruim, regular ou bom, sendo correlacionados estatisticamente com a flexibilidade, a gravidade da deformidade e a adesão ao tratamento, com avaliação um ano após o fim do tratamento e na maturidade esquelética. Resultados: A idade média no início do tratamento foi de 13,7 anos e o seguimento médio foi de 25.7 meses após a suspensão do uso da órtese. 48% dos casos apresentaram sucesso com o tratamento, mas quando os exercícios e o uso da órtese foram regulares, esta taxa aumentou para 70% (p < 0,001). Os casos mais leves tiveram maior sucesso que os de maior gravidade (p = 0,007), mas a flexibilidade inicial não influenciou os resultados (p = 0,63). Conclusão: O tratamento do pectus excavatum amplo com o uso de órtese e exercícios apresentou bons resultados definitivos na maioria dos pacientes resilientes, em especial nos casos mais leves.

ABSTRACT Objective: Pectus excavatum is a deformity that affects aesthetics and causes emotional disorders. Surgical correction is well established, but conservative treatment is less common. We investigated the long-term results of using a brace and performing specific physical exercises to treat localized pectus excavatum, a type of deformity in which the depressed area is restricted to the midline region along the nipple line. Methods: We selected 115 patients (mean age 12.8 years), with a minimum follow-up of 36 months, who were evaluated more than one year after the end of treatment and skeletal maturity. Results were correlated with deformity flexibility, severity, regular use of the device, and performance of specific exercises. The chi-square (χ2) and the Cochran-Mantel-Haenszel tests were used for statistical analysis. Results: Treatment was successful in 58% of patients, however, when exercises were performed and the brace was used regularly by patients with flexible deformities, the rate increased to 83% (p = 0.005). Severity and adherence to treatment greatly impacted successful treatment (p = 0.009 and < 0.001, respectively). Conclusion: The proposed treatment method was effective for correction or partial correction of the deformity in motivated patients followed up until skeletal maturity, especially when started early in milder and more flexible deformities. Level of Evidence V, Expert opinion.
RESUMO Objetivo: O pectus excavatum é uma deformidade importante por comprometer a estética e causar distúrbios emocionais. A sua correção cirúrgica é bem estabelecida, mas o tratamento conservador é menos familiar. Investigamos os resultados de longo prazo do tratamento do pectus excavatum localizado (deformidade restrita a linha média e na linha mamilar) com uso de órtese e exercícios físicos específicos. Métodos: Selecionamos 115 pacientes (média de 12,8 anos) com seguimento mínimo de 36 meses, sendo avaliados mais de um ano após o término do tratamento e maturidade esquelética. Os resultados foram relacionados estatisticamente (qui-quadrado e Cochran-Mantel-Haenszel) com a flexibilidade da deformidade, a gravidade, o uso regular da órtese e a realização de exercícios específicos. Resultados: O tratamento foi bem-sucedido em 58% dos pacientes, mas quando o uso da órtese e os exercícios foram regulares em pacientes com deformidades flexíveis, essa taxa aumentou para 83% (p = 0,005). A gravidade e a adesão ao tratamento tiveram grande impacto no sucesso do tratamento (p = 0,009 e <0,001, respectivamente). Conclusão: O método de tratamento proposto foi eficaz para correção total ou parcial da deformidade em pacientes motivados acompanhados até a maturidade esquelética, principalmente quando a terapêutica foi iniciada precocemente em deformidades mais leves e flexíveis.

Objective:To explore the incidence and risk factors of intercostal muscular avulsion for pectus excavatum after Nuss procedure.Methods:From April 2012 to April 2019, the clinical data were analyzed retrospectively for 159 hospitalized cases of Nuss procedure for pectus excavatum in Xi'an Children' s Hospital. The age ranged from 3.2 to 17.0 years old, mean(6.8±3.4) years old; 124 males, 35 females. Haller index ranged from 2.7 to 7.5(mean 4.0±1.0); intercostal muscular avulsion was 13 cases, 9 males, 4 females.The age ranged from 3.4 to 18.4 years old, mean(4.8±1.5) years old. Follow-ups were conducted for at least 20 months.Analyzed retrospectively the relevant data included age, gender, haller index, t test and χ2 test was used for statistical analysis.Results:There were statistically significant differences between intercostal muscle avulsion and age after funnel chest operation ( P=0.001), and between intercostal muscle avulsion and typing( P=0.034). Children at young ages and asymmetric pectus excavatum were prone to intercostal muscle avulsion. There were no significant differences in gender, Haller index, surgical method and intercostal muscle avulsion( P>0.05). Conclusion:The cause of intercostal muscle avulsion after postoperative complication of pectus infundibulis Nuss is mostly related to age. Children at young ages, especially asymmetric pectus excavatum are prone to intercostal muscle avulsion. We recommend surgery after the age of 6 for avoid intercostal muscle avulsion after funnel chest operation.
摘要
Abstract Introduction: The erector spinae plane (ESP) block is a relatively new interfascial block about which several applications have been described, both in abdominal and thoracic surgical procedures. Case presentation: A 17-year old patient programed for removal of a Nuss bar through mini-thoracotomy. Following the induction with anesthesia, a US-guided bilateral ESP block was administered; no pain was reported during the immediate postoperative period and over the 48-hour follow-up. Conclusion: Bilateral ESP block seems to be promising, easy to administer, and an acceptable alternative to the epidural catheter (the gold standard in the management of analgesia for thoracic surgery), providing adequate and opiate-free analgesia.
Resumen Introducción: El bloqueo erector de la espina (ESP) es un bloqueo interfascial relativamente nuevo, sobre el cual se han descrito diferentes aplicaciones, tanto en cirugías abdominales como torácicas. Presentación del caso: Paciente de 17 años programado para el retiro de una barra de Nuss por minitoracotomía, a quien, después de la inducción anestésica, se le realizó un bloqueo ESP bilateral guiado con ecografía, y en su posoperatorio inmediato y seguimiento a las 48 horas no reportó dolor alguno. Conclusión: El bloqueo ESP bilateral parece ser prometedor, de fácil realización y apunta a ser una alternativa aceptable al catéter epidural (estándar de oro en el manejo analgésico en cirugías de tórax), por la cual se obtiene analgesia adecuada y libre de opioides.

ABSTRACT Objective: Minimally invasive repair of pectus excavatum (MIRPE) is a surgical treatment for PE. During the procedure, a specialized introducer is used to tunnel across the mediastinum for thoracoscopic insertion of a metal bar. There have been reported cases of cardiac perforation during this risky step. The large introducer can be a dangerous lever in unskilled hands. We set out to determine the safety and feasibility of using regular instruments (i.e., not relying on special devices or tools) to create the retrosternal tunnel during MIRPE. Methods: This was a preliminary study of MIRPE with regular instruments (MIRPERI), involving 28 patients with PE. We recorded basic patient demographics, chest measurements, and surgical details, as well as intraoperative and postoperative complications. Results: Patients undergoing MIRPERI had Haller index values ranging from 2.58 to 5.56. No intraoperative complications occurred. Postoperative complications included nausea/vomiting in 8 patients, pruritus in 2, and dizziness in 2, as well as atelectasis, pneumothorax with thoracic drainage, pleural effusion, and dyspnea in 1 patient each. Conclusions: In this preliminary study, the rate of complications associated with MIRPERI was comparable to that reported in the literature for MIRPE. The MIRPERI approach has the potential to improve the safety of PE repair, particularly for surgeons that do not have access to certain special instruments or have not been trained in their use.
RESUMO Objetivo: O minimally invasive repair of pectus excavatum (MIRPE, reparo minimamente invasivo do pectus excavatum) é um tratamento cirúrgico do PE. Durante o procedimento, utiliza-se um introdutor específico a fim de criar um túnel mediastinal para a colocação toracoscópica de uma barra metálica. Já houve casos relatados de perfuração cardíaca durante essa etapa arriscada. O introdutor grande pode ser uma perigosa alavanca em mãos inábeis. Propusemo-nos a determinar a segurança e viabilidade do uso de instrumentos comuns (isto é, sem contar com dispositivos ou ferramentas especiais) para criar o túnel retroesternal durante o MIRPE. Métodos: Estudo preliminar sobre o MIRPE with regular instruments (MIRPERI, MIRPE com instrumentos comuns), envolvendo 28 pacientes com PE. Foram registrados dados demográficos básicos dos pacientes, medições torácicas e detalhes cirúrgicos, bem como complicações intra e pós-operatórias. Resultados: Os pacientes submetidos ao MIRPERI apresentavam índice de Haller entre 2,58 e 5,56. Não ocorreram complicações intraoperatórias. As complicações pós-operatórias incluíram náusea/vômito em 8 pacientes, prurido em 2 e tontura em 2, bem como atelectasia, pneumotórax com drenagem torácica, derrame pleural e dispneia em 1 paciente cada. Conclusões: Neste estudo preliminar, a taxa de complicações associadas ao MIRPERI foi comparável à relatada na literatura para o MIRPE. A abordagem de MIRPERI tem o potencial de melhorar a segurança do reparo do PE, particularmente para cirurgiões que não têm acesso a certos instrumentos especiais ou não foram treinados para utilizá-los.

Abstract Introduction: Significant anatomical and functional changes occur following pneumonectomy. Mediastinal structures displace toward the side of the resected lung, pulmonary reserve is reduced. Owing to these changes, surgical access to heart and great vessels becomes challenging, and there is increased risk of postoperative pulmonary complications. Methods: We performed a mitral valve replacement combined with a Ravitch procedure in a young female with previous left pneumonectomy and pectus excavatum. Results: She was discharged on postoperative day 9 and remains symptom-free 3 months after surgery. Conclusion: Thorough preoperative evaluation and intensive respiratory physiotherapy are essential before performing cardiac operations on patients with previous pneumonectomy.

Objective To evaluate the effect of bilateral thoracic paravertebral block (TPVB) combined with general anesthesia on early recovery after Nuss procedure in patients with pectus excavatum.Methods Sixty patients of both sexes with pectus excavatum,aged 8-18 yr,with body mass index＜ 18.5-32.0 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective Nuss procedure,were divided into 2 groups by using a random number table method:general anesthesia group (group GA,n=30) and bilateral TPVB combined with general anesthesia group (group TPVB+ GA,n=30).Bilateral TPVB was performed at the level of T5 under ultrasound guidance at 30 min before operation in group TPVB+GA.Anesthesia was induced by intravenous injection of fentanyl,propofol and rocuronium and maintained by inhalation of sevoflurane,intravenous infusion of remifentanil 0.1-0.5 μg · kg-1 · min-1,and intermittent intravenous boluses of rocuronium.Patients received patient-controlled intravenous analgesia after operation.Tramadol 1-2 mg/kg or dizocin 0.1 mg/kg was intravenously injected as rescue analgesic,maintaining visual analogue scale score ≤ 3 within 2 days after operation.The intraoperative consumption of remifentanil,postoperative consumption of snfentanil,requirement for rescue analgesia and development of nausea and retching/vomiting were recorded.Quality of recovery was assessed using the Quality of Recovery-15 at 1 and 2 days after operation.Results Compared with group GA,the intraoperative consumption of remifentanil,postoperative consumption of sufentanil,rate of rescue analgesia and incidence of nausea and vomiting were significantly decreased,and Quality of Recovery-15 scores were increased at 1 and 2 days after operation in group TPVB +GA (P＜0.05).Conclusion Bilateral TPVB combined with general anesthesia can reduce the perioperative consumption of opioids and is beneficial for the early recovery after Nuss procedure in patients with pectus excavatum.
摘要
BACKGROUND: The nonsurgical treatment of chest wall deformity by a vacuum bell or external brace is gradual, with correction taking place over months. Monitoring the progress of nonsurgical treatment of chest wall deformity has relied on the ancient methods of measuring the depth of the excavatum and the protrusion of the carinatum. Patients, who are often adolescent, may become discouraged and abandon treatment. METHODS: Optical scanning was utilized before and after the intervention to assess the effectiveness of treatment. The device measured the change in chest shape at each visit. In this pilot study, patients were included if they were willing to undergo scanning before and after treatment. Both surgical and nonsurgical treatment results were assessed. RESULTS: Scanning was successful in 7 patients. Optical scanning allowed a visually clear, precise assessment of treatment, whether by operation, vacuum bell (for pectus excavatum), or external compression brace (for pectus carinatum). Millimeter-scale differences were identified and presented graphically to patients and families. CONCLUSION: Optical scanning with the digital subtraction of images obtained months apart allows a comparison of chest shape before and after treatment. For nonsurgical, gradual methods, this allows the patient to more easily appreciate progress. We speculate that this will increase adherence to these methods in adolescent patients.

Objective Based on the disadvantages of NUSS procedure, we design a new type of funnel chest orthodontic steel bars for clinical application to simplify surgery operation , reduce the surgical trauma, improve operation effect, enhance the safety of operation, and relieve the suffering of the patients, etc.Methods From June 2010 to July 2015, 1020 patients used the new type of funnel chest orthodontic metal plates, including 706 cases of males and 314 cases of females, aged 3-40(aver-age age 11.38 ±5.31).Haller index of 3.36 to 15.45(average index 4.97 ±1.58).668 symmetrical funnel chest cases, 281 cases of asymmetry and 71 recurrent funnel chest cases are involved.Surgical steel bars, having 15 specifications, are arc-shaped, the lengths of which are from 12cm to 26cm.The two ends of steel bars have fixed piece, one end of the bar was fused with a stabilizer and the other end connected to an introducer or a stabilizer and use screws to fix two ends .Steel plates, as the design product, are finalized in the factory.Therefore we need not make intraoperative reprocess.Front tip of introducer and the back-end can be connected to the metal plate.Patients were placed supine position under general anesthesia.Two inci-sions, with length about 2cm and deep to the rib periosteum were made along axillary midline line on the both sides .In the di-rection of high blunt slightly medial free for subcutaneous tunnel to the highest point .Fixed wires were worn around the ribs on both sides.A thoracoscope to guide the bar was inserted from the highest point on the right side of the rear of the medial by sternum low into the chest from the left corresponds to the highest point of the medial , remove the introducer to connect another stator, use screws to fix the connection, with a fixed stator and steel plate stabilized.At the end of the surgery, the stabilizer on either side was secured with sutures.Results The median first operation time was 23 -45(32.31 ±3.57)min, second op-eration time was about 34-147(68.27 ±30.25)min..The bleeding volume(first operation) was 0-2(0.40 ±0.36)ml, the bleeding of second operation time was 1-630(144.00 ±57.00)ml.The hospital stay was 3-9(4.22 ±0.61)days after the operation.All the cases were followed up for 34-48(34.4 ±6.1)months.Steel plate was fixed at the bottom of the sternum in 957 of them,with slight shifting in 58 patients.There was another 5 cases who need re-operation because of the obvious shift-ing.Conclusion The new type of funnel chest orthodontic steel bars simplify surgery operation, reduce the surgical trauma, improve operation effect, relieve the suffering of the patients and enhance the safety of operation.
摘要
OBJECTIVE: In pectus excavatum patients, Nuss procedure provides excellent cosmetic results, but it cause hypoxemia and hypercarbia by the reduction of alveolar ventilation due to severe thorax expansion and pain after operation. This study was designed to evaluate the effect of different oxygen flow rates via a nasal cannula in recovery room after correction of pectus excavatum by Nuss procedure. METHODS: Forty patients (3–12 years old) undergoing pectus excavatum repair were randomly assigned and divided into two groups. Patients were given 200 mL/kg/min flow of 100% oxygen (group 1) and 100 mL/kg/min flow of oxygen (group 2) via nasal cannula in the recovery room. Arterial blood gas analysis and peripheral oxygen saturation were measured at arrival and after 5, 10, 15, and 30 minutes in the recovery room. RESULTS: In group 1 compared with group 2, decrease of PaCO2 (partial pressure of CO2 in arterial blood) accumulation was observed in 5, 10, and 15 minutes. Arterial oxygen pressure (PaO2) difference was not significant between the group. But, in comparison within groups, PaO2 level was significantly higher at 5, 10, 15, and 30 minutes than just after arrival at the recovery room. In both group, heart rate and systolic blood pressure were no significant difference. CONCLUSION: We recommend that 200 mL/kg/min flow of 100% oxygen should be administered to patients who were taken Nuss procedure for prevention of hypoxemia and hypercarbia in recovery rooms.

Pectus arcuatum is a rare complex chest wall deformity. A 31-year-old female presented with a severely protruding upper sternum combined with a concave lower sternum. We planned a modified Ravitch-type operation. Through vertical mid-sternal incision, chondrectomies were performed from the second to fifth costal cartilages, saving the perichondrium. Horizontal osteotomy was performed in a wedge shape on the most protruding point, and followed by an additional partial osteotomy at the most concaved point. The harvested wedge-shape bone fragments were minced and re-implanted to the latter osteotomy site. The osteotomized sternum was fixed with multiple wirings. With chondrosternoplasty, a complex chest wall deformity can be corrected successfully.

BACKGROUND: Pectus excavatum (PE) and pectus carinatum (PC) are the most common chest wall deformities. In this study, we aimed to characterize how patients obtained information about these deformities, as well as patients' family history, associated medical problems, and postoperative satisfaction after the Nuss and Abramson procedures. METHODS: This cross-sectional retrospective study included patients who were operated by a single surgeon between 2006 and 2013. Follow-up calls were made after approval of our institution's ethics committee. We reached 207 of the 336 PE patients (61.6%) and 73 of the 96 PC patients (76%). RESULTS: The majority of the patients were male (85% of the PE patients and 91.8% of the PC patients). The age of diagnosis of PE was 14.52+/-0.51 years and the age at the time of operation was 17.89+/-0.42 years; for PC patients, the corresponding ages were 15.23+/-0.55 years and 16.77+/-0.55 years, respectively. A total of 70% of the PE patients and 63.8% of the PC patients obtained information about pectus deformities through the Internet. In 27.1% of the PE patients with an associated anomaly, 57.1% (n=13) had scoliosis, while 41.1% of the PC patients with an associated anomaly had kyphosis (n=5). Postoperative satisfaction, as evaluated on a scale from 0 to 10, was 8.17+/-0.15 for PE patients and 8.37+/-0.26 for PC patients. The postoperative pain duration was 51.93+/-5.18 days for PE patients and 38.5+/-6.88 days for PC patients. CONCLUSION: In this study, we found that most patients with pectus deformities were male. The Internet was an important resource for patients to learn about their deformities. Family history and associated anomalies were identified as important aspects for consideration in the clinical setting. The patients reported high levels of postoperative satisfaction, and pain management was found to be one of the most important elements of postoperative care.

Pectus excavatum é a deformidade congênita na parede torácica anterior mais comum e seu tratamento é essencialmente cirúrgico. Tratamentos cirúrgicos e repouso prolongado no leito levam a alterações metabólicas, músculoesqueléticas, cardiovasculares e respiratórias, que podem prolongar o tempo necessário para a recuperação funcional dos pacientes no pós-operatório, aumentar o tempo de internação e os custos em saúde. A reabilitação precoce após cirurgias, com a realização de exercícios físicos e respiratórios, reduzir estes efeitos adversos, garante melhor recuperação pós-operatória, com aumento da independência dos pacientes, maior bem-estar psicológico e melhores resultados funcionais. O objetivo deste estudo foi avaliar se os pacientes submetidos a reabilitação precoce após correção cirúrgica de Pectus excavatum pela técnica de Nuss apresentam melhor capacidade funcional de exercício e função pulmonar no dia da alta hospitalar quando comparados com os pacientes submetidos a cuidados convencionais. Os Candidatos a correção cirúrgica foram alocados aleatoriamente em 2 grupos: o grupo reabilitação precoce (GRP), que iniciou a intervenção logo após a cirurgia e o grupo de cuidados convencionais (GC), que recebeu os cuidados de rotina da instituição. O teste de função pulmonar por meio da espirometria simples e a avaliação da capacidade funcional de exercício pelo teste de caminhada de seis minutos (TC6), foram realizados antes da cirurgia (pré-operatório) e no dia da alta hospitalar (pós-operatório). Quarenta pacientes foram analisados, 20 em cada grupo. No teste de função pulmonar, todos os pacientes apresentaram redução significativa dos valores de CVF, VEF1 e PFE no pós-operatório, sem diferença entre os grupos. Todos os pacientes apresentaram redução significativa da distância percorrida no TC6 pós-operatório comparada com a distância percorrida no pré-operatório (p < 0,005). Houve diferença estatisticamente significante entre o...
Pectus excavatum is the most common congenital chest wall deformity and its treatment is essentially surgical. Surgical treatments and postoperative bed rest lead to metabolic, musculoskeletal, cardiovascular and respiratory alterations, with the possibility of prolonging the time required for postoperative patient recovery, increasing hospitalization time and health expenditure. Early rehabilitation after surgeries, which involves physical and breathing exercises, reduces these adverse effects and ensure better postoperative recovery, with increased independence of patients, greater psychological well-being and better functional outcomes. The objective of this study was to assess whether patients undergoing early rehabilitation after Pectus excavatum repair using the Nuss procedure have better functional exercise capacity and lung function on hospital discharge day compared with patients undergoing conventional care. Patients were randomly allocated into two groups: the early rehabilitation group (ERG) which started rehabilitation after surgery and the group of conventional care (CG) which received routine care of the institution. The lung function was assessed by simple spirometry and the functional exercise capacity by the 6-minute walk test (6MWT) were performed before surgery (preoperative) and in hospital discharge day (postoperative). Forty patients were evaluated, 20 in each group. All patients presented a significant reduction in FVC, FEV1 and PEF in the postoperative lung function test and there was no statistically significant difference between groups. All patients showed significant reduction in postoperative distance walked in 6MWT compared with the preoperative distance (p < 0.005). There was statistically significant different in functional exercise capacity between the ERG and CG in the postoperative evaluation (506.26 ± 66.54 vs 431.11 ± 75.61, p=0.02) and the difference between distance walked in the preoperative and postoperative period...

BACKGROUND: Pectus excavatum (PE) is the most common chest wall deformity. The Nuss Questionnaire modified for Adults (NQmA) is a disease-specific health-related quality of life assessment tool for patients with pectus deformities. The aim of this study is to adapt the NQmA into Turkish. METHODS: Two hundred and sixty-five patients with PE were participated, with an age range of 14 to 29 years. All patients underwent a physical examination and had not undergone corrective surgery. The Turkish version of the NQmA was completed by patients and their parents. RESULTS: The content validity index based on expert opinions was 91% for the patient questionnaire and 96% for the parent questionnaire. The Cronbach's alpha value for the NQmA was found to be 0.805 for the patient questionnaire and 0.800 for the parent questionnaire. Exploratory factor analysis was used to assess construct validity. Two factors explained 51.1% of the total variance in the patient questionnaire (psychosocial: 31.145%, Cronbach's alpha=0.818; physical: 19.955%, Cronbach's alpha=0.862). In the parent questionnaire, two factors explained 51.422% of the total variance (psychosocial: 26.097%, Cronbach's alpha=0.743; physical: 25.325%, Cronbach's alpha=0.827). Construct validity was confirmed by confirmatory factor analysis. CONCLUSION: The Turkish version of the NQmA was found to be valid and reliable for the assessment of quality of life in patients with PE.
