Efficacy of endoscopic removal in the treatment of subglottic ductal cysts. / Eficacia de la escisión endoscópica en el tratamiento de los quistes ductales subglóticos.

INTRODUCTION: Subglottic cyst is a rare cause of airway obstruction, and there is a lack of evidence about the best treatment in the literature. This report describes our experience with endoscopic removal. MATERIAL AND METHODS: A retrospective study of all patients undergoing endoscopic removal of subglottic cyst at our healthcare facility between 2014 and 2019 was performed. Clinic and demographic data regarding gestational age, intubation, comorbidities, surgical procedures, first symptoms, endoscopic findings, treatment, and follow-up were collected. RESULTS: Four patients were identified. Two out of four (50%) were preterm, and all patients were intubated during their neonatal period. Median age and weight at diagnosis were 6.5 months (6-8) and 5.9 kg (3.6-7). Median time between last intubation and diagnosis was 119.5 days (71-171). Biphasic stridor and progressive respiratory distress were the most common clinical symptoms. Airway obstruction of at least 50% was found during upper airway endoscopy in all patients. Endoscopic removal was performed as a first-line treatment in 3 patients, and as a second-line treatment in 1 patient. Median intubation time after treatment and hospital stay were 13.5 hours (0-48) and 7 days (6-9). All four patients are free of disease, with a median follow-up of 17.5 months (6-42). CONCLUSION: Subglottic cyst is a rare cause of post-extubation stridor. Endoscopic removal seems to be a feasible and effective treatment with a low recurrence rate.

INTRODUCCION: Los quistes ductales subglóticos adquiridos (QDSA) son una causa rara de obstrucción de la vía aérea, sin consenso en la literatura en cuanto al tratamiento más eficaz. Presentamos nuestra experiencia en el tratamiento de los QDSA. MATERIAL Y METODOS: Estudio retrospectivo de los pacientes tratados en nuestro centro por QDSA en los últimos 5 años. Se recogieron los antecedentes de intubación, la clínica presentada, el tratamiento realizado, la evolución postquirúrgica, el seguimiento en consulta y los controles endoscópicos. RESULTADOS: Se identificaron 4 pacientes, con unas medianas de edad y peso de 6,5 meses (6-8) y 5,9 kg (3,6-7), respectivamente. Todos presentaron antecedentes de intubación por intervenciones quirúrgicas, siendo prematuros 2 de ellos. La mediana entre la última intubación y el diagnóstico fue de 119,5 días (71-171). La clínica consistió en estridor bifásico con mejoría postural presentando una ocupación de la luz traqueal de más del 50% en la endoscopia diagnóstica. Se realizó escisión endoscópica (EE) al diagnóstico en 3 de los pacientes y como técnica de rescate en el cuarto por recidiva tras tratamiento con drenaje y dilatación con balón. La mediana de tiempo de intubación postquirúrgico fue de 13,5 horas (0-48) y la estancia hospitalaria de 7 días (6-9). Tras un seguimiento mediano de 17,5 meses (6-42) no se ha presentado ninguna recidiva. CONCLUSION: Los QDSA son una causa poco frecuente de estridor post-extubación. La EE permite un tratamiento eficaz con baja tasa de recidiva.

[Management of suspected foreign body aspiration in children. 10-year experience in a single center]. / Sospecha de aspiración de cuerpos extraños en pacientes pediátricos. Nuestra experiencia en 10 años.

INTRODUCTION: Foreign body aspiration (FBA) is a potentially life-threatening event, and is the leading cause of death in children after road traffic injuries. If suspected, a prompt exploration of the airway should be performed. We present our experience in FBA treatment in the last 10 years. MATERIAL AND METHODS: A retrospective study of patients admitted in our center with suspected FBA between 2005 and 2015 was performed. Clinical history, physical findings, radiologic imaging, treatment and evolution were assessed. RESULTS: A total of 115 children (70 M/45 F) with a median age of 2 years old (8 months-13 years), presented with a clinical history of FBA. All of them suffered a choking event and the most frequent symptoms were persistent cough (88.3%) and respiratory distress (46.8%). Pathologic physical examination was registered in 75% and an abnormal chest X-ray was seen in 72%. Rigid bronchoscopy (RB) was performed in 100% based on compatible history, regardless of physical and radiologic exams. A foreign body was found during RB in 78 patients (68.1%) and the most frequent were seeds and nuts (63.4%), located mainly in the right bronchus (46.8%). If the criteria for RB had been based on a compatible history along with clinical findings and abnormal chest X-ray, 21 foreign bodies (26.9%) would have been missed, with the subsequent risk of sudden death. All the foreign bodies were removed with success, without any immediate complication during the procedure. CONCLUSION: FBA is a frequent accident among children. The history, clinical findings and imaging cannot always concur. In case of a positive history of FBA an examination of the tracheobronchial tree must be done.

OBJETIVOS: La aspiración de cuerpos extraños (ACE) es una urgencia pediátrica frecuente, descrita como segunda causa de muerte infantil tras los accidentes de tráfico. Presentamos nuestra experiencia en el tratamiento de la ACE en los últimos 10 años. MATERIAL Y METODOS: Estudio retrospectivo de pacientes atendidos por sospecha de ACE entre los años 2005-2015, describiendo historia clínica, sintomatología, pruebas de imagen, procedimiento y evolución. RESULTADOS: Un total de 115 pacientes (70 V/45 M), con una mediana de 2 años (8 meses-13 años), presentaron historia sugestiva de ACE. Los síntomas más frecuentes fueron: tos (88,3%) y dificultad respiratoria (46,8%). El 75% presentaban exploración física patológica y un 72% presentaban alteraciones en la radiografía de tórax. Se realizó broncoscopia rígida (BR) en el 100% de los pacientes con historia compatible, sin importar los resultados de la exploración física o las pruebas de imagen. En 78 pacientes (68,1%) se encontró un cuerpo extraño (CE) durante la BR, siendo los más frecuentes semillas y frutos secos (63,4%); localizándose sobre todo en el bronquio derecho (46,8%). Si el criterio para realizar una BR se hubiese basado en la historia compatible, junto con alteraciones en la exploración física y pruebas de imagen, 21 CE (26,9%) no habrían sido diagnosticados con el consiguiente riesgo de muerte. Todos los CE se extrajeron con éxito, sin ninguna complicación inmediata. CONCLUSIONES: La ACE es frecuente en la infancia. La historia y los hallazgos clínico-radiológicos pueden no concordar, por lo que ante historia sugestiva de ACE es recomendable una exploración de la vía aérea, dado el bajo riesgo que asocia.

[Bean or blue rubber blue nevus syndrome. Presentation of 6 patients]. / Síndrome de bean o Blue rubber bleb nevus syndrome. presentación de 6 pacientes.

INTRODUCTION/AIMS: Bean or Blue Rubber Bleb Nevus Syndrome (BRBNS) is an uncommon disease characterized by multifocal venous malformations that predominantly affect the skin, soft tissues and gastrointestinal tract. Our objective is to familiarize the pediatric surgeon with this condition, promoting early diagnosis and seriated surgical treatment as therapeutic options. We have reviewed the diagnosis and treatment of 6 patients treated from 1993 to 2009. MATERIAL AND METHODS: All the patients had a venous malformation (> 10 cm) that acted as a marker. After, characteristic skin lesions appeared as well as chronic anemia due to digestive bleeding associated to hypofibrinogenemia. Age of appearance of the anemic picture varied from 6 months to 7 years, it being more aggressive the earlier its appearance. The diagnosis of the disease was made by endoscopically. All the patients required transfusion with blood derivatives 5 to 25 times a year. Treatment was multidisciplinary: periodic transfusions in every case, endoscopic sclerosis in lesions that affect the colon or stomach and surgical treatment for lesions of the jejunum and ileum. In two of these patients, 23 and 46 lesions were excised, respectively. In the last year, the tendency has been to use enterotomy and fulguration with Argon. RESULTS: The patients who have undergone excision of the digestive malformations have experienced a significant decrease in their transfusion needs. One female patient with miliary dissemination died. CONCLUSIONS: BRBNS is a difficult to diagnose due to its low frequency. Treatment of gastrointestinal tract lesions is multidisciplinary, combining endoscopic and surgical techniques that decrease transfusions and improve the quality of life of the patients.
