ABSTRACT
Introducción. La ingesta de cáusticos continúa siendo un problema de salud pública en los países en vía de desarrollo, por lo que a veces es necesario realizar un reemplazo esofágico en estos pacientes. Aún no existe una técnica estandarizada para este procedimiento. Caso clínico. Masculino de 10 años con estenosis esofágica por ingesta de cáusticos, quien no mejoró con las dilataciones endoscópicas. Se realizó un ascenso gástrico transhiatal por vía ortotópica mediante cirugía mínimamente invasiva como manejo quirúrgico definitivo .Discusión. Actualmente existen varios tipos de injertos usados en el reemplazo esofágico. La interposición colónica y gástrica son las que cuentan con mayores estudios, mostrando resultados similares. Conclusiones. La elección del tipo y posición del injerto debe ser individualizada, tomando en cuenta las características de las lesiones y la anatomía de cada paciente para aumentar la tasa de éxito.
Introduction. The ingestion of caustics continues to be a public health problem in developing countries, which is why sometimes is necessary to perform an esophageal replacement in these patients. There is still no standardized technique for this procedure. Clinical case. A 10-year-old male with esophageal stricture due to caustic ingestion, who did not improve with endoscopic dilations. A laparoscopic transhiatal gastric lift was performed orthotopically as definitive surgical management using minimally invasive surgery. Discussion. Currently there are several types of grafts used in esophageal replacement. Colonic and gastric interposition are the ones that have the most studies, showing similar results. Conclusions. Choice of type and position of the graft must be individualized, taking into account the characteristics of the lesions and anatomy of each patient, in order to increase the success rate.

Objective:To investigate the characteristics, process, and prognosis of esophageal stricture after circumferential endoscopic submucosal dissection (ESD), and to preliminarily analyze the prevention and treatment effects of simple dilation, stent placement, mucosal transplantation, and glucocorticoid (hereinafter referred to as hormone) application in esophageal stricture.Methods:From August 2017 to March 2022, at the First Affiliated Hospital of Zhengzhou University, the clinical and follow-up data of 55 patients who underwent circumferential ESD for early esophageal cancer and precancerous lesions were retrospectively analyzed. According to the prevention and treatment methods for esophageal stricture, the patients were divided into two groups: simple dilation group (23 cases) and combined dilation group (32 cases). The combined dilation group was divided into mucosal transplantation subgroup (9 cases), stent placement subgroup (14 cases), hormone application subgroup (7 cases), and bleomycin subgroup (2 cases, excluded from comparative analysis due to limited cases). Overall prognosis of patients was observed. Treatment efficacy, prognosis, and adverse events were compared among the simple dilation group, mucosal transplantation subgroup, stent placement subgroup, and hormone application subgroup. Independent samples t-test, chi-square test, and Fisher′s exact test were used for statistical analysis. Results:Among the 55 patients, the follow-up time was (894.1±417.7) days. Refractory esophageal stricture (total dilation times ≥ 5) occurred in 33 patients (60.0%). Fifty-two patients (94.5%) achieved clinical remission of the stricture. The total number of dilations was 5.8±4.0, and the average dysphagia-free period was (52.3±37.1) days. The dysphagia-free period of mucosal transplantation subgroup was longer than that of the simple dilation group, stent placement subgroup, and hormone application subgroup ((114.5±50.0) days vs. (40.9±20.0), (39.7±10.0), and (40.9±25.5) days, respectively), and the differences were statistically significant ( t=4.82, 3.77 and 3.14, P<0.001, =0.011, =0.009). There were no statistically significant differences between the simple dilation group and the mucosal transplantation subgroup, stent placement subgroup, and hormone application subgroup in the total number of dilations (6.8±4.8 vs. 3.0±2.5, 5.8±2.2, and 5.7±5.0), stricture remission rate (95.7%, 22/23 vs. 8/9, 13/14, and 7/7), and incidence of adverse events (17.4%, 4/23 vs. 5/9, 5/14, and 2/7; all P>0.05). Conclusions:Esophageal stricture formed after circumferential ESD shows the characteristics of recurrence and intractability. The over all number of dilations is high, and the average dysphagia-free period is short. Most patients can achieve clinical remission of the stricture after multiple times of endoscopic dilation treatment. However mucosal transplantation, stent placement, and hormone application cannot well intervene the natural process of esophageal stricture.
ABSTRACT
Objective:To investigate the consistency between the iodine-unstained area and the pathological size of endoscopic submucosal dissection (ESD) specimens of superficial esophageal cancer.Methods:A retrospective study was performed on data of 32 patients with superficial esophageal cancer who accepted ESD from May 2019 to April 2020 in the First Affiliated Hospital, Zhejiang University School of Medicine. The maximum transverse diameter and maximum longitudinal diameter of the iodine-unstained area were compared with the tumor pathological area. A size difference no more than 0.5 cm was considered as conformity, any difference between 0.5 and 1.0 cm was considered as non-conformity, and any difference no less than 1.0 cm was considered as serious non-conformity. At the same time, pink sign after spraying Lugo solution and the consistency of pink sign area with the iodine free area were observed.Results:A total of 32 patients with 33 lesions were enrolled in this study, including 23 males and 9 females and the age of the patients was 59.5±7.3 years. There were 19 (57.6%) lesions whose size of iodine-unstained area was consistent with the tumor pathological area. These 19 lesions were all positive for the pink sign, and the pink sign area overlapped with the iodine-unstained area. In addition, 4 (12.1%) iodine-unstained areas of the lesions did not match the size of the pathological area, and 10 (30.3%) iodine-unstained areas of the lesions were seriously inconsistent with the size of the pathological area. These 14 (42.4%) lesions were all positive for pink sign, and the pink sign area was significantly smaller than the iodine-unstained area. Among the 14 discordant lesions, 2 lesions underwent ESD according to the iodine-unstained area, which resulted in excessive resection and postoperative stenosis.Conclusion:Determining the extent of superficial esophageal cancer by iodine-unstained areas before ESD may lead to excessive resection of the lesions, which is related to the fact that the iodine-unstained areas of the lesions are sometimes significantly larger than the pink sign areas. Therefore, in order to achieve precise treatment, endoscopists can choose the iodine-unstained area with positive pink sign as the first choice for resection.
ABSTRACT
To investigate the effect of long-term indwelling gastric tube on the prevention and treatment of esophageal stenosis after endoscopic submucosal dissection (ESD) for esophageal circumferential superficial cancer, data of patients with esophageal circumferential superficial cancer who underwent ESD in the First Affiliated Hospital of Nanjing Medical University from January 2018 to December 2021 were retrospectively analyzed. There were 15 patients with gastric tube placement (GTP) after ESD (the GTP group ), and 23 patients without GTP (the non-GTP group). The general information, lesion location, pathological stage, postoperative complications, degree of esophageal stenosis (water intake), pain conditions, number of hospitalizations and medical expenses were compared between the two groups. The results showed that there was no significant difference in age, gender, lesion location or postoperative pathological stage between the two groups ( P>0.05). Compared with the non-GTP group, the rate of water intake in the GTP group was significantly higher (11/15 VS 6/23, P<0.05), the frequency of pain was less in the GTP group (7.3±3.1 times VS 10.7±3.6 times, t=3.00, P<0.05), and the number of hospitalizations and the medical expenses after ESD to before and after stent placement were significantly lower in the GTP group than those in the non-GTP group ( P<0.05). There were no significant differences in the incidence of delayed bleeding and perforation, or time of the first stenosis after ESD between the two groups ( P>0.05). The results of the study initially showed that long-term indwelling gastric tube after ESD can reduce the degree of esophageal stenosis with good safety for esophageal circumferential superficial lesions.
ABSTRACT
Objective:To investigate the risk factors of restenosis after dilation of anastomotic stenosis in patients with esophageal cancer surgery.Methods:Clinical data of 997 patients who underwent endoscopic dilation due to anastomotic stenosis after esophageal cancer radical surgery in the Affiliated Huai′an First Hospital of Nanjing Medical University from June 2015 to July 2021, were retrospectively analyzed. There were 486 cases receiving single dilation (single dilation group) and 511 cases receiving more than two dilations (multiple dilation group). The risk factors of restenosis were explored using univariate and multivariate logistic regression analysis.Results:There were 682 males and 315 females with a median age of 65 years, the median distance between the stenosis and incisor was 20 (20, 22) cm, the median stenosis diameter was 4 (3, 5) mm, and the median stenosis diameter after dilation was 11 (11, 13) mm. Univariate analysis showed that there were significant differences in the distance of the stenosis and incisor ( Z=-2.303, P<0.05), stenosis diameter ( Z=-4.637, P<0.05) and stenosis diameter after dilation ( Z=-5.773, P<0.05) between single and multiple dilation groups. Stratified multivariate logistic regression showed that for male patients, risk of multiple dilations dropped by approximately 3% for every 1-mm increase in the distance between the stenosis and incisor ( OR=0.97, 95% CI:0.93-1.00, P=0.047); the risk of multiple dilations decreased by about 15%, for every 1-mm increase in stenosis diameter ( OR=0.85, 95% CI:0.76-0.94, P=0.004); the risk of multiple dilations decreased by about 13% for every 1-mm increase in stenosis diameter after dilation ( OR=0.87, 95% CI:0.78-0.96, P=0.007). For females patients under 60 years old, the risk of multiple dilations decreased by about 31%, for every 1-mm increase in stenosis diameter after dilation ( OR=0.69, 95% CI:0.47-0.98, P=0.049); for female patients≥60 years old, the risk decreased by about 5%, for every 1-year increase in age ( OR=0.95, 95% CI:0.91-1.00, P=0.037), risk of multiple dilations dropped by 17%( OR=0.83, 95% CI:0.70-0.99, P=0.039) for every 1 mm increase in stenosis diameter after dilation. Stratified smooth curve fitting indicated that the distance between the stenosis and incisor≤23 mm, stenosis diameter≤4.5 mm, stenosis diameter after dilation≤12 mm were risk factors for multiple dilations. Conclusions:The study indicates that patients with the distance between the stenosis and incisor≤23 mm, stenosis diameter≤4.5 mm, stenosis diameter after dilation≤12 mm may need multiple dilations; and the first dilation should expand the stenosis diameter to 12 mm or above as far as possible to reduce the risk of restenosis in patients receiving esophageal cancer radical surgery.
ABSTRACT
Introdução: Crianças menores de cinco anos são as principais vítimas de acidentes por ingestão de cáusticos, assim considerando a epidemiologia brasileira e dos riscos à exposição desses agentes ressalta-se a importância deste estudo que objetiva realizar uma análise descritiva dos casos de acidentes cáusticos em pacientes pediátricos atendidos em um hospital universitário de Minas Gerais. Método: Este é um estudo transversal descritivo, de caráter quantitativo, a partir dos dados obtidos de prontuários de pacientes pediátricos (0-13 anos) atendidos por ingestão de substâncias cáusticas, no Hospital de Clínicas da Universidade Federal de Uberlândia (Minas Gerais, Brasil). Resultados: Foram levantados 132 prontuários de crianças atendidas por ingestão de substâncias cáusticas de janeiro de 2011 a abril de 2018. Os acidentes acometeram crianças na faixa etária de 08 meses a 12 anos, sendo que 82,60% dos casos ocorreram em ambiente domiciliar. Entre as principais substâncias ingeridas estão os produtos de limpeza, quanto à sua composição química predominaram soda cáustica, hipoclorito de sódio e amoníaco. A endoscopia digestiva alta (EDA) foi realizada em 104 pacientes. Quase 13% das crianças apresentaram estenose esofágica e necessitaram de dilatação esofágica. No período estudado, foram realizados 296 procedimentos de dilatações, com média de 17,4 procedimentos por paciente. Discussão: Considerando que os acidentes cáusticos são prevalentes em crianças menores de cinco anos e em ambiente domiciliar, as principais substâncias ingeridas são aquelas de caráter alcalino, que causam lesão no trato respiratório e gastrointestinal, sendo a principal consequência a estenose esofágica. Ademais, não há protocolos bem definidos para o manejo e a condução de pacientes que fizeram a ingestão dessas substâncias. As principais limitações do estudo foram o preenchimento incompleto dos prontuários analisados e os trâmites burocráticos para o acesso aos mesmos. Conclusão: Predominaram os acidentes cáusticos domiciliares e em crianças menores de 2 anos, o que implica a necessidade de ações educativas e preventivas. [au]
Introduction: Children under five years old are the principal victims of accidents caused by the ingestion of caustics, so considering Brazilian epidemiology and the risks of exposure to these agents the importance of this study is emphasized. This study aims to carry out a descriptive analysis of cases of caustic accidents in pediatric patients treated in a university hospital in Minas Gerais. Method: This is a descriptive cross-sectional study, with a quantitative character, based on data obtained from medical records of pediatric patients (0-13 years old) treated for ingestion of caustic agents at the Hospital of the Federal University of Uberlândia (Minas Gerais, Brazil). Results: We collected 132 medical records of children treated for ingestion of caustic substances from January 2011 to April 2018. The accidents affected children aged between 8 months and 12 years, with 82.60% of the cases occurring in the home environment. Among the main substances ingested are cleaning products, as for their chemical composition, caustic soda, sodium hypochlorite, and ammonia predominated. Upper digestive endoscopy (UGE) was performed in 104 patients. Almost 13% of the children had esophageal strictures and required esophageal dilation. During the study period, 296 dilatation procedures were performed, with an average of 17.4 procedures per patient. Discussion: Considering that caustic accidents are prevalent in children under five years of age and the home environment, the main substances ingested are those of an alkaline nature, which cause injury to the respiratory and gastrointestinal tract, the main consequence being esophageal stenosis. Furthermore, there are no well-defined protocols for the management of patients who have ingested these substances. The main limitations of the study were the incomplete filling of the medical records analyzed and the bureaucratic procedures for accessing them. Conclusion: Caustic accidents predominated in children under two years old in the home environment, which implies the need for educational and preventive actions. [au]

Materiales y Método: Un estudio observacional, transversal, con recolección de datos retrospectivo, donde se incluyeron todos los expedientes de pacientes que presentaban patología del esófago por causa adquirida o congénita que fueron operados de sustitución esofágica con tubo gástrico invertido en dos hospitales pediátricos durante 3 años. Resultados: Encontramos 29 niños sometidos a sustitución esofágica, de los cuales 27 cumplieron criterios de inclusión. La edad comprendida entre 2 y 17 años. El 63% corresponde al sexo femenino. La causa más frecuente de sustitución esofágica es por estenosis esofágica por ingesta caustica (92,59%). El 70% presentó algún tipo de complicación luego de la cirugía. La fístula esofagocutánea es la complicación principal con 33,33%. La permanencia en la unidad de cuidados intensivos es menor de 24 horas en un 74% de los niños. Se inicia la vía oral en casi la mitad de casos entre los 10-12 días de posquirúrgico, la estancia hospitalaria es en promedio 18,5 días. La mortalidad es 3,7%. Conclusión: La sustitución esofágica por tubo gástrico invertido vía ascenso retroesternal, es una técnica comparable en resultados a la interposición de colón. Para los autores, el estómago es un órgano ideal para realizar la reconstrucción esofágica, y sus complicaciones son manejables.
Aim: To describe the results of esophageal replacement surgery with an inverted gastric tube via retrosternal ascent in two pediatric hospitals during the period March 2015 to March 2018. Materials and Method: an observational, cross-sectional study with retrospective data collection that included all the records of patients with esophageal discontinuity due to acquired or congenital causes who underwent esophageal replacement surgery with an inverted gastric tube in two pediatric hospitals for 3 years. Results: We found 29 children undergoing esophageal replacement, of which 27 met inclusion criteria. The age between 2 to 17 years. 63% corresponds to the female sex. The most frequent cause of esophageal replacement is esophageal stricture due to caustic ingestion (92.59%). 70% presented some type of complication after surgery. The esophagocutaneous fistula is the main complication with 33.33%. The stay in the intensive care unit is less than 24 hours in 74% of children. The oral route is started in almost half of cases between 10-12 days after surgery; the hospital stay is on average 18.5 days. Mortality is 3.70%. Conclusión: The esophageal substitution by inverted gastric tube via retrosternal ascent is a technique comparable in results to the interposition of the colon. For the authors, the stomach is an ideal organ to perform esophageal reconstruction, and its complications are manageable.

ABSTRACT BACKGROUND: Caustic ingestion is still a health problem of utmost importance in the West. In developing countries, this incident remains at increase and it is associated with unfavorable factors like social, economic, and educational handicaps, besides a lack of prevention. Esophagocele is a rare consequence of caustic ingestion. AIM: We aimed to describe a patient with multiple caustic ingestions who presented an esophagocele resected by videothoracoscopy. METHODS: A woman ingested caustic soda when she was only 17 years old in a suicidal attempt during a depressive crisis. Initially, she was submitted to a retrosternal esophagocoloplasty with the maintenance of her damaged esophagus. After 1 year of this first surgery, she ingested caustic soda again in a new suicidal attempt. Her transposed large bowel in the first surgery became narrow, being replaced in a second surgery by a retrosternal esophagogastroplasty. Still, at the second surgery, her damaged esophagus remained in its original position in the posterior mediastinum. However, after 5 years, she developed an esophagocele. RESULTS: The esophagocele was resected through videothoracoscopy in a prone position, employing four trocars. The postoperative was uneventful. CONCLUSION: Esophageal exclusion must always be recorded because esophagocele presents unspecific symptoms. The videothoracoscopy in a prone position is an excellent technical option to resect esophagoceles.
RESUMO RACIONAL: A ingestão de produtos cáusticos ainda é um problema de saúde de extrema importância no Ocidente. Nos países em desenvolvimento, este incidente continua em ascensão e está associada a fatores desfavoráveis como sociais, econômicos e educacionais, além da falta de prevenção. A esofagocele é uma consequência rara da ingestão de cáusticos. OBJETIVO: Nosso objetivo é descrever um paciente com múltiplas ingestões cáusticas que apresentou uma esofagocele ressecada por videotoracoscopia. MÉTODOS: Doente feminina que ingeriu soda cáustica com 17 anos de idade, como tentativa de suicídio, durante uma crise depressiva. Inicialmente, foi submetida a esofagocoloplastia retroesternal com manutenção do esôfago lesado. Após um ano desta primeira cirurgia, voltou a ingerir soda cáustica, em nova tentativa de suicídio. Seu intestino grosso transposto na primeira cirurgia tornou-se estenosado, sendo substituído em uma segunda cirurgia, por esofagogastroplastia retroesternal. Ainda assim, nesta segunda cirurgia, o esôfago lesado permaneceu em sua posição original no mediastino posterior. No entanto, após cinco anos, ela desenvolveu uma esofagocele. RESULTADOS: A esofagocele foi ressecada por videotoracoscopia, em decúbito ventral, empregando-se quatro trocartes. O pós-operatório transcorreu sem intercorrências. CONCLUSÕES: A exclusão esofágica deve ser sempre registrada, pois a esofagocele apresenta sintomas inespecíficos. A videotoracoscopia em posição prona é uma excelente opção técnica para ressecção de esofagoceles.
ABSTRACT
Introducción. El divertículo de Zenker es una evaginación sacular ciega que puede presentarse a nivel faringoesofágico. No se conoce exactamente su incidencia en la edad pediátrica, constituyendo una patología muy infrecuente. La sintomatología es inespecífica, lo que dificulta el diagnóstico precoz y determina un mayor riesgo de complicaciones asociadas. Caso clínico. Paciente preescolar femenina con cuadro recurrente de emesis con deshidratación, posteriormente asociado a disfagia, a quien se le diagnosticó un divertículo de Zenker. Se realizó tratamiento quirúrgico con hallazgo intraoperatorio de dilatación esofágica, un área de estenosis secundaria al hallazgo incidental de un cuerpo extraño y divertículo de Zenker en la región lateral del esófago dilatado. Discusión. Esta patología es extremadamente rara, pero se debe tener en cuenta dentro de los diagnósticos diferenciales en pacientes con sintomatología faringo-esofágica. Conclusión. Se presenta una preescolar sin antecedente de procedimientos esofágicos o malformaciones congénitas asociadas con diagnóstico de un divertículo de Zenker y dilatación esofágica por un cuerpo extraño, tratada quirúrgicamente de forma exitosa.
Introduction. Zenker's diverticulum is a blind saccular evagination that can present at the pharyngoesophageal level. Its incidence in pediatric age is not exactly known, constituting a very infrequent pathology. The symptoms are nonspecific, which makes early diagnosis difficult and determines a higher risk of associated complications.Clinical case. Female preschool patient with recurrent dehydration due to emesis, later associated with dysphagia, who was diagnosed with Zenker's diverticulum. Surgical treatment was performed with intraoperative finding of esophageal dilation, an area of stenosis secondary to the incidental finding of a foreign body, and a Zenker's diverticulum in the lateral region of the dilated esophagus. Discussion. This pathology is extremely rare, but it should be taken into account within the differential diagnoses in patients with pharyngo-esophageal symptoms. Conclusion: We present a preschool female patient with no history of esophageal procedures or congenital malformations associated with a diagnosis of Zenker's diverticulum and esophageal dilation due to a foreign body, successfully treated surgically.

To investigate the efficacy and safety of endoscopic bougie dilation and stent implantation for pediatric caustic esophageal stenosis. Clinical characteristics, diagnosis and treatment of children with pediatric caustic esophageal stenosis from October 2009 to December 2019 at Department of Gastroenterology, the Seventh Medical Center of PLA General Hospital were retrospectively analyzed. A total of 50 caustic esophageal stenosis cases were enrolled, among whom, 94.0% (47/50) received conservative treatment before sending to our hospital. Thirty-six (72.0%) of them accidently ingested caustic substance of alkali and 22.0% (11/50) of them accidently ingested caustic substance of acid. Forty-six children (92.0%) who ingested caustic agents were younger than 7 years old. The stenosis was more common in the upper esophagus, accounting for 64.0% (32/50). Twenty-seven cases (54.0%) underwent simple bougie dilation and 16 cases (32.0%) underwent bougie dilation combined with stent treatment. All 50 children underwent a total of 1 260 expansions. The numbers of simple dilations and dilations combined with stent implantation were 37.8±26.2, 20.9±12.6 respectively with significant difference ( t=2.453, P=0.021). Among them, 2 cases (4.0%) underwent surgery, 5 cases (10.0%) underwent surgery combined with dilatation and stent implantation. The stenosis diameter widened significantly after treatment (1.1±0.2 cm VS 0.2±0.1 cm, t=23.004, P<0.001), and the Stooler grade of dysphagia improved significantly (grade 3.5±0.5 VS 1.2±0.7, t=19.925, P<0.001). Perforation occurred in only 1 patient, who was cured by conservative treatment with stent implantation. The total effective rate was 100.0% (50/50) and the satisfaction rate was 98.0% (49/50). Endoscopic bougie dilation and bougie dilation combined with stent implantation is safe and effective for pediatric caustic esophageal stenosis. Combination with stent implantation can reduce the number of dilation times.
ABSTRACT
Objective:To summarize the clinical features, diagnosis and treatment experience of esophageal hamartoma in children.Methods:From December 2013 to December 2019, 3 cases of esophageal hamartoma were admitted to our hospital, and a retrospective analysis was conducted.Results:There were 1 male and 2 females, with an average age of 6.4 years old. The clinical manifestations were vomiting in 2 cases and dysphagia with esophageal foreign body sensation in 1 case. Esophagography, chest contrast-enhanced CT, and esophagoscopy showed esophageal stenosis or esophageal mass effectg, and esophageal dilatation above the affected segment. The tumor was found in upper esophagus in 1 case and lower esophagus in 2 cases. Tumors were complete resection in all 3 cases and the patients were discharged smoothly. All the 3 cases were followed up after surgery for 10-74 months(average 37 months), and 1 case had gastroesophageal reflux. No stenosis or recurrence was found in all the cases, and all the patients could eat normal diet.Conclusion:The main manifestations of esophageal hamartoma in children are vomiting and choking. Complete surgical resection is the main treatment method, and the prognosis is good.
ABSTRACT
ABSTRACT BACKGROUND: Esophageal stenosis (ES) in children is a fixed intrinsic narrowing of the esophagus due to numerous aetiologies. OBJECTIVE: This study aimed to determine the clinical and nutritional impacts of endoscopic balloon dilation (EBD) in Iranian children with an esophageal stricture. METHODS: This retrospective study, pediatric patients (aged <18 years) who underwent EBD for esophageal stricture from April 2015 until March 2020 in Abuzar Children's Hospital (Ahvaz, Iran) were enrolled in the study. Outcome parameters were the frequency of dilations, nutritional status, complications, and clinical success rates. EBD was used in children with radiologic evidence of esophageal stenosis. The nutritional status was evaluated by weight-for-age (z-score). Clinical success was considered as no necessity of EBD for a minimum of one year and/or increasing interval among dilation and the frequency of EBD was less than four times per year. RESULTS: A total of 53 cases (mean age, 4.72±3.38 years) were enrolled. There were 25 (47.2%) females and 28 (52.8%) males. During follow-up, a total of 331 EBD sessions were performed, with an average of 6.24 sessions per patient. There was one case of perforation and one case of mediastinitis, while there was no other complication or mortality. The clinical success rate of EBD therapy was 62.3% (33/53). The mean standard deviation z-score weight-for-age of patients before and after endoscopic dilation was 2.78 (2.41) and 1.18 (1.87), respectively. The t-test showed a significant difference between the weights-for-age (z-score) before and after endoscopic dilation. The majority of the patients had raised weight-for-age (z-score) after EBD treatment. CONCLUSION: EBD attained a good clinical success rate and nutritional improvement in children with an esophageal stricture.
RESUMO CONTEXTO: Estenose esofágica (EE) em crianças é um estreitamento intrínseco fixo do esôfago devido a inúmeras etiologias. OBJETIVO: Este estudo teve como objetivo determinar os impactos clínicos e nutricionais da dilatação do balão endoscópico (DBE) em crianças iranianas com restrição esofágica. MÉTODOS: Foram inscritos neste estudo retrospectivo, pacientes pediátricos (com idade <18 anos) submetidos a DBE para restrição esofágica de abril de 2015 a março de 2020 no Hospital Infantil de Abuzar (Ahvaz, Irã). Os parâmetros de desfecho foram a frequência de dilatações, o estado nutricional, complicações e taxas de sucesso clínico. A DBE foi usada em crianças com evidência radiológica de estenose esofágica. O estado nutricional foi avaliado pelo peso-por-idade (escore z). O sucesso clínico foi considerado como não necessidade de DBE por um período mínimo de um ano e/ou aumento de intervalo entre dilatações e frequência inferior a quatro vezes por ano. RESULTADOS: Foram incluídos 53 casos (média de idade, 4,72±3,38 anos). Eram 25 mulheres (47,2%) e 28 homens (52,8%). Durante o acompanhamento, foram realizadas 331 sessões de DBE, com média de 6,24 sessões por paciente. Houve um caso de perfuração e um caso de mediastinite, enquanto não houve outra complicação ou mortalidade. A taxa de sucesso clínico da terapia de DBE foi de 62,3% (33/53). A média (escore z) peso-para-idade dos pacientes antes e depois da dilatação endoscópica foi de 2,78 (2,41) e 1,18 (1,87), respectivamente. O teste t mostrou uma diferença significativa entre os pesos por idade (escore z) antes e depois da dilatação endoscópica. A maioria dos pacientes havia aumentado o peso por idade (escore z) após o tratamento com DBE. CONCLUSÃO: A DBE atingiu boa taxa de sucesso clínico e melhora nutricional em crianças com restrição esofágica.
ABSTRACT
Abstract Esophageal trauma is a rare but life-threatening event associated with high morbidity and mortality. An inadvertent esophageal perforation can rapidly contaminate the neck, mediastinum, pleural space, or abdominal cavity, resulting in sepsis or septic shock. Higher complications and mortality rates are commonly associated with adjacent organ injuries and/or delays in diagnosis or definitive management. This article aims to delineate the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia, on the surgical management of esophageal trauma following damage control principles. Esophageal injuries should always be suspected in thoracoabdominal or cervical trauma when the trajectory or mechanism suggests so. Hemodynamically stable patients should be radiologically evaluated before a surgical correction, ideally with computed tomography of the neck, chest, and abdomen. While hemodynamically unstable patients should be immediately transferred to the operating room for direct surgical control. A primary repair is the surgical management of choice in all esophageal injuries, along with endoscopic nasogastric tube placement and immediate postoperative care in the intensive care unit. We propose an easy-to-follow surgical management algorithm that sticks to the philosophy of "Less is Better" by avoiding esophagostomas.
Resumen El trauma esofágico es un evento poco frecuente pero potencialmente mortal. Una perforación esofágica inadvertida puede ocasionar la rápida contaminación del cuello, el mediastino, el espacio pleural o la cavidad abdominal, lo cual puede resultar en sepsis o choque séptico. Las complicaciones y la mortalidad aumentan con el retraso en el diagnóstico o manejo definitivo, y la presencia de lesiones asociadas. El objetivo del presente artículo es describir la experiencia adquirida por el grupo de cirugía de Trauma y Emergencias (CTE) de Cali, Colombia en el manejo del trauma de esófago de acuerdo con los principios de la cirugía de control de daños. Las lesiones esofágicas deben sospecharse en todo trauma toraco-abdominal o cervical en el que el mecanismo o la trayectoria de la lesión lo sugieran. El paciente hemodinámicamente estable se debe estudiar con imágenes diagnósticas antes de la corrección quirúrgica del defecto, idealmente por medio de tomografía computarizada del cuello, tórax y abdomen con contraste endovenoso. Mientras que en el paciente hemodinámicamente inestable se debe explorar y controlar la lesión. El reparo primario es el manejo quirúrgico de elección, con la previa colocación de una sonda nasogástrica y el seguimiento postoperatorio estricto en la unidad de cuidado intensivo. Se propone un algoritmo de manejo quirúrgico que resulta fácil de seguir y adopta la premisa "Menos es Mejor" evitando realizar derivaciones esofágicas.
ABSTRACT
ABSTRACT BACKGROUND: Caustic ingestion and development of esophageal strictures are recognized major public health problems in childhood. Different therapeutic methods have been proposed in the management of such strictures. OBJECTIVE: To evaluate efficacy and risk of endoscopic topical application of mitomycin C in the treatment of caustic esophageal strictures. METHODS: We searched MEDLINE, EMBASE, Central Cochrane, and LILACS databases. The outcomes evaluated were dysphagia resolution rate, number of dilations performed in resolved cases, and the number of dilations performed in all patients. RESULTS: Three randomized clinical trials were included for final analysis with a total of 190 patients. Topical mitomycin C application group showed a significant increase in dysphagia resolution rate, corresponding to a 42% higher dysphagia resolution as compared to endoscopic dilation alone, with statistical significance between the two groups (RD: 0.42 - [CI: 0.29-0.56]; P-value <0.00001). The mean number of dilations performed in resolved cases were significantly less in the topical mitomycin C application group, compared to endoscopic dilations alone, with statistical significance between the two groups (MD: 2.84 [CI: 1.98-3.69]; P-value <0.00001). When comparing the number of dilations in all patients, there was no statistical difference between the two groups (MD: 1.46 [CI: -1.53-4.44]; P-value =0.34). CONCLUSION: Application of topical mitomycin C with endoscopic dilations in caustic esophageal strictures was more effective in dysphagia resolution than endoscopic therapy alone in the pediatric population. Moreover, topical mitomycin C application also reduced the number of dilation sessions needed to alleviate dysphagia without rising morbidity.
RESUMO CONTEXTO: A ingestão de soda cáustica e o desenvolvimento de estenoses esofágicas são reconhecidos como importantes problemas de saúde pública na infância. Diferentes métodos terapêuticos têm sido propostos no manejo dessas estenoses. OBJETIVO: Avaliar a eficácia e o risco da aplicação endoscópica tópica de mitomicina C no tratamento de estenoses esofágicas cáusticas. MÉTODOS: Buscamos as bases de dados MEDLINE, EMBASE, Central Cochrane e LILACS. Os desfechos avaliados foram taxa de resolução da disfagia, número de dilatações realizadas nos casos resolvidos e número de dilatações realizadas em todos os pacientes. RESULTADOS: Três ensaios clínicos randomizados foram incluídos para análise final com um total de 190 pacientes. O grupo de aplicação de mitomicina C tópica apresentou aumento significativo na taxa de resolução da disfagia, correspondendo a uma resolução da disfagia 42% maior em comparação à dilatação endoscópica isolada, com significância estatística entre os dois grupos (RD: 0,42 - [IC: 0,29-0,56]; P-valor <0,00001). O número médio de dilatações realizadas em casos resolvidos foi significativamente menor no grupo de aplicação tópica de mitomicina C, em comparação com as dilatações endoscópicas isoladas, com significância estatística entre os dois grupos (MD: 2,84 [IC: 1,98-3,69]; P-valor <0,00001). Ao comparar o número de dilatações em todos os pacientes, não houve diferença estatística entre os dois grupos (MD: 1,46 [IC: -1,53-4,44]; valor de P=0,34). CONCLUSÃO: A aplicação de mitomicina C tópica com dilatações endoscópicas em estenoses esofágicas cáusticas foi mais eficaz na resolução da disfagia do que a terapia endoscópica isolada na população pediátrica. Além disso, a aplicação tópica de mitomicina C também reduziu o número de sessões de dilatação necessárias para aliviar a disfagia sem aumentar a morbidade.

ABSTRACT Purpose To investigate the efficacy of cordycepin, an adenosine analogue, on prevention of esophageal damage and stricture formation due to esophageal caustic burns in rat model comparing with prednisolone. Methods Caustic esophageal burn was introduced by 37.5% of NaOH to distal esophagus. Thirty-two Wistar albino rats were divided in four groups: sham rats undergone laparotomy, treated with 0.9% NaCl; control rats injured with NaOH without cordycepin treatment; cordycepin group injured with NaOH, treated with 20 mg/kg cordycepin; prednisolone group injured with NaOH, treated with 1 mg/kg prednisolone for 28 days. Efficacy was assessed by histopathological and immunohistochemical analysis of esophageal tissues. Results Cordycepin treatment significantly decreased inflammation, granulation tissue and fibrous tissue formation and prevented formation of esophageal strictures shown by histopathological damage score and stenosis indexes compared to control group (p < 0.01). These effects are relatively more substantial than prednisolone, probably based on attenuation of elevation of proinflammatory cytokines hypoxia-inducible factor 1-alpha (HIF-1?), tumor necrosis factor alpha (TNF-?), proliferative and fibrotic factor fibroblast growth factor 2 (FGF2) and angiogenic factor vascular endothelial growth factor A (VEGFA) (p < 0.05). Conclusions The findings suggest that cordycepin has a complex multifactorial healing process in alkali-burned tissue, more successful than prednisolone in preventing the formation of esophageal strictures and may be used as a therapeutic agent in the acute phase of esophageal alkali-burn.

Data of 7 patients with complex benign esophageal strictures (CBESs) who underwent endoscopic longitudinal incision combined with local injection of bleomycin were retrospectively reviewed at Air Force Medical Center from August 2018 to November 2019.The length of preoperative esophageal stenosis was 4-14 cm and the minimum diameter of esophageal stenosis was 0.2-0.4 cm in 7 cases. The procedure was successful for all 7 patients.No adverse events occurred during 5-14 months of follow-up period.Restenosis and dysphagia occurred in 5 cases.The interval between the first endoscopic treatment and the recurrence of esophageal stenosis was 30-120 days.Among the 5 cases of recurrence, 4 cases remained unobstructed after 2 treatments and 1 case remained unobstructed after 4 treatments. The dysphagia scores of 7 patients were graded from 0 to 1 by the end of follow-up. Endoscopic longitudinal incision combined with bleomycin therapy in treatment of CBESs is safe and effective.
ABSTRACT
Objective:To investigate the risk factors of esophageal stenosis after endoscopic submucosal dissection (ESD) of early esophageal cancer and precancerous lesions, and to construct and assess a predictive model for esophageal stenosis.Methods:Data of 421 patients with early esophageal cancer or precancerous lesions who underwent ESD and were confirmed by pathology in the First Affiliated Hospital of Zhengzhou University between January 2015 and April 2020 were retrospectively analyzed.Eighty-nine cases developed postoperative esophageal stenosis (stenosis group) and 332 cases did not (non-stenosis group). Risk factors of esophageal stenosis were investigated by univariate and multivariate logistic regression analysis. Independent risk factors were used as predictors to construct a nomogram model by using the lasso algorithm.The accuracy of the model was evaluated by the consistency index (C-index) and the calibration curve. Bootstrap was applied to internal verification to avoid over-fitting of the model.Results:Univariate analysis showed that postoperative pathology, depth of infiltration, median long and short diameters of the specimen, circumferential resection range, and muscularis propria injury were related to postoperative esophageal stenosis( P<0.05). Further multivariate logistic regression analysis showed that the resection range≥1/2 of the circumference (VS <1/2 circumference: P<0.01, OR=48.453, 95% CI: 11.288-207.983), muscularis propria injury( P<0.01, OR=4.671, 95% CI: 2.283-9.557)and longitudinal length≥50 mm (VS <50 mm: P=0.008, OR=2.741, 95% CI: 1.299-5.785) were independent risk factors for esophageal stenosis after ESD. The nomogram model was constructed through the lasso algorithm by taking the longitudinal length, circumferential resection range, and muscularis propria injury as the predictive factors. The C-index of the nomogram was 0.934 (95% CI: 0.909-0.959)and was 0.931 after 100 times of Bootstrap internal sampling, which meant the prediction probability of the model in the calibration curve was in good agreement with the actual observation probability. Conclusion:Circumferential resection range ≥1/2, muscularis propria injury, and longitudinal length≥50 mm are independent risk factors for post-ESD esophageal stenosis. The nomogram model constructed by the above three indicators as predictors shows an ideal prediction effect on esophageal stenosis after ESD for early esophageal cancer and precancerous lesions, which is helpful to establish a standard plan for early intervention in patients at high risk of stenosis after ESD.
ABSTRACT
Objective:To investigate the characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection (ESD) for early esophageal carcinoma.Methods:Patients who underwent ESD in the Digestive Endoscopy Center of the Second Affiliated Hospital of Army Medical University from January 2011 to December 2018 were included. The data were obtained from medical records and follow-up. The influencing factors of stenosis were determined by single factor and Cox regression analysis.Results:A total of 654 patients underwent ESD and 79 (12.1%) of them developed postoperative esophageal stenosis. The median time of stenosis development was 27 (17, 43) days. The morphology and lesion circumferential proportion were independent factors for the occurrence of stenosis after ESD. The stenosis incidence of type Ⅱa was 6.601 times (95% CI: 1.518-28.709, P=0.012) compared with that of type Ⅱc. The incidence of stenosis in lesions with 75%-<100% and 100% circumference was 17.408 times (95% CI: 8.009-37.839, P<0.001)and 52.439 times (95% CI: 23.905-115.029, P<0.001) respectively compared with that of patients <75%. Among the 79 patients, 27 had severe stenosis, and the lesion circumferential proportion was an independent factor for stenosis. Compared with the group of lesion circumferential proportion of less than 75%, the incidences of stenosis of lesion circumferential proportion of 75%-<100% and 100% were 7.775 (95% CI: 1.977-30.577, P=0.003) and 70.062 (95% CI: 19.879-246.926, P<0.001) times respectively. Conclusion:The morphology and lesion circumferential proportion are two independent factors for the occurrence of esophageal stenosis after ESD. Additionally, lesion circumferential proportion is an independent factor for the occurrence of severe esophageal stenosis after ESD.
ABSTRACT
Objective:To evaluate the long-term efficacy and safety of a novel self-help inflatable balloon to prevent esophageal stenosis after extensive endoscopic submucosal dissection (ESD).Methods:Patients with early esophageal cancer or precancerous lesions, undergoing ESD in the First Medical Center of Chinese PLA General Hospital from January 2018 to December 2019 were included in the prospective study, who had post-ESD mucosal defect greater than 5/6 of the esophageal circumference and 30-100 mm in length. The self-help inflatable balloon was used to prevent esophageal stenosis after ESD. Mucosal defect of ESD was divided into grade 1 (≥5/6 and less than the whole circumference) and grade 2 (the whole circumference). The incidence of stricture, the time from ESD to the occurrence of stricture, the total number of endoscopic balloon dilations (EBD) or radial incision and cuttings (RIC), and other adverse events were observed.Results:A total of 27 patients met the including criteria with follow-up time of 14-38 months, including 3 patients of grade 1 and 24 of grade 2. The ulcer longitudinal length was 73.7±18.4 mm. The time of wearing balloons was 92.0±20.0 days. The overall frequency of stricture was 18.5% (5/27), and the stricture incidence of patients of grade 2 resection was only 16.7% (4/27). The median time from balloon removal to stricture was 17 days. To treat the stricture, two patients received 3 EBD sessions, and three other patients received 2, 1 and 2 RIC sessions, respectively. No balloon was removed in advance, and none had a perforation or delayed bleeding.Conclusion:The self-help inflatable balloon shows high efficacy and safety in preventing esophageal stenosis in patients with mucosal defect greater than 5/6 of the esophageal circumference and less than 100 mm in length after extensive esophageal ESD.
ABSTRACT
Objective:To analyze the clinical characteristics, endoscopic manifestations, complications and related risk factors of button battery ingestion in 58 children, thus providing the basis for clinical diagnosis and treatment.Methods:The medical data of 58 children with button battery ingestion were collected and researched at Children′s Hospital Affiliated to Zhengzhou University from September 2015 to September 2020.The demographic information, battery impaction location, duration, symptoms, mucosal injury level, battery size, treatment, complications and follow-up results were analyzed.Results:The average age of the patients with button battery ingestion was (25.7±15.4)months, including 40 boys(68.9%). The average retention time of the battery in digestive tract was 13.8(2, 96) h. Vomiting, salivation, dysphagia, cough and fever were the common chief complaints.There were 29(50.0%) cases of grade I mucosal injury, as well as 14(24.1%) cases, 10(17.2%) cases and 10(17.2%) cases for grade Ⅱ, grade Ⅲ and grade Ⅳ, respectively.Additionally, common complications included esophageal stenosis, esophageal perforation and esophageal-tracheal fistula.Logistic regression analysis showed that location(esophagus) and diameter(≥15 mm) of battery incarceration were important predictors of complications.Conclusion:The degree of mucosal damage is associated with the diameter and impaction location of battery.The button battery embedded in the esophagus is prone to complications, while the ones retained in the stomach were not vulnerable to serious complications.Endoscopy and other related examinations should be performed again in 1 to 3 weeks after the button removal to determine the outcome of complications and to intervene in time.
