Introduction. Foreign body ingestion is a common cause of consultation in the pediatric practice. Even though the most frequent ingested objects are coins, the button disk batteries are becoming a serious problem. Objectives: To describe the main esophageal lesions caused by the ingestion of button disk batteries, their response to treatment and clinical evolution. Methods. Files from patients admitted to our hospital with diagnosis of button disk battery ingestion between December 1996 to December 2007 were reviewed. We analyzed sex, age, symptoms, evolution time, radiological and endoscopical findings, management, complications and long term sequels. Results. We found 21 cases, male preponderance 4:1, age rank from 3 months to 12 years. Sialorrhea was the main symptom. Average time to treatment was 39.6 hours. Battery removal was accomplished with direct esophagoscopy using Jackson laryngoscope in 14 patients, rigid esophagoscope in 2 patients, and flexible esophagoscopy in 4. In most of the cases the battery was lodged in the proximal third of the esophagus. At endoscopic exploration, esophageal ulcers were found in 8 patients, necrosis in 6, ulcers and necrosis in 1, partial perforation in 1, perforation with traqueoesophageal fistula in 2, and no injury in 3 patients. Only 5 patients evolved to esophageal stenosis that resolved with dilatations. Two patients with perforation and traqueoesophageal fistula underwent surgical treatment, one of them died. Another patient with perforation was lost to follow up because of voluntary discharge. Conclusions. Button disk battery ingestion is becoming a more frequent event; removal from the esophagus should be an urgent procedure to avoid severe complications such as stenosis and traqueoesophageal fistula.

Introduction: Every year about 5,000 are reported a10, 000 patients with congenital or acquired esophageal requiring surgical treatment, unlike the rest of the gastrointestinal tract is not possible to use autologous tissue for reconstruction because of its limited size and its delicate vascularity, which are used by complex procedures such as colon interposition, a field that has been growing and could provide a solution to these problems is tissue engineering. The purpose of this work involves the construction of a esophageal prosthesis from autologous cells implanted on a collagen matrix and test its usefulness in an animal model. Material and Methods: We took a biopsy of healthy esophageal tissue at the neck of healthy rabbits, which were processed to desegregate its cellular components in epithelial and muscle cell viability was verified by MTT method and their presence by electron microscopy scanning. The prosthesis was implanted in a second surgery to create a defect in "patch" in the native esophagus, further studies of endoscopy, esophagogram and necropsy in animals. Results: After the biopsy epithelial and muscle cells were isolated and multiplied sown and harvested in Petri dishes and seeded at a concentration of 1x! 07 cel/cm2 in intestinal submucosa prostheses. Subsequently, the prostheses were implanted in four healthy rabbits N = 5, all rabbits subsequently underwent esophagogram and endoscopy studies, observing proper integration of the now called neoesófago, with adequate passage of contrast medium showed no leakage or stenosis, all animals remained alive, feeding by mouth without complications so far from being slaughtered except one who died for reasons unconnected with the study. In histopathological studies, there is an almost normal architecture neoesófago presence of mucosa and muscle layer proper. Conclusion: In this study we establish the conditions, general characterization for the isolation and multiplication of epithelial cells and muscle tissue healthy esophageal also created an esophageal prosthesis, which could be implanted in animals to which a defect was created 50 % of the light of it with proper integration of the now called neoesófago. All animals remained alive feeding by mouth without complications, which lays the basis for developing an esophageal prosthesis in the future which can be used in the treatment of children with congenital or acquired esophageal lesions.

Introduction: Foreign body (FB) ingestion is a common home accident during childhood; a timely management by the specialists may help prevent complications in the short and long term., Objective: To describe the characteristics and complications of FB ingestion located in the gastrointestinal tract in the pediatric population., Material and Methods: Two phases, retrospective, and prospective study. Patients diagnosed with FB ingestion between January 1971 and December 2016 were included. The general characteristics of patients, FB type, removal method, and complications were registered. A descriptive analysis was performed., Results: Over 45 years, 2637 FBs were removed from the pharynx (n= 118), the esophagus (n= 2410), the stomach (n= 103), and the intestines (n= 6). Male patients predominated (50.9%); 74% were younger than 5 years. Besides, 57% arrived within the first 24 hours; ptyalism, dysphagia, and vomiting were the main symptoms; 16% of patients had no symptoms. It was possible to locate the FB using an X-ray in 93% of cases; the most common FBs were coins (78%); the most frequent location was the upper third of the esophagus (79%); 86% of FBs were removed using a rigid endoscope, and complications were observed in 7.8% of patients., Conclusions: FB ingestion predominated among children younger than 5 years; metal objects were the most common ones. A plain X-ray is the test of choice for diagnosis; removal is usually done with a rigid or flexible endoscope, depending on the endoscopist's experience., (Sociedad Argentina de Pediatría.)

Introduction: Congenital pulmonary malformations are a rare cause of neonatal morbidity. Some of them have a common origin, which allows the identification of combined lesions. Its diagnosis can be made prenatally by ultrasound, with the limitation that this study is performed in specialized centers and depends on the expertise of the operator. The association of pulmonary sequestration and congenital malformation of the airway has been described in approximately 40-60 cases since its first description in 1949. Many lesions are not perceptible in intrauterine life and in the neonatal period there are recurrent respiratory symptoms that in some cases are associated with a congenital pulmonary malformation., Case Report: We report the case of a young infant, who was diagnosed with pulmonary sequestration at 24 weeks of gestational age, undergoing intrauterine surgical treatment with a report of complete resolution of the malformation in posterior ultrasounds. She was valued by pediatric pneumology at 4 months of age, where angiotomography was performed and the presence of pulmonary sequestration was confirmed by lobectomy. The histopathological study reported extralobar pulmonary sequestration with congenital malformation of the pulmonary airway type 2. These combined lesions were identified by histopathological study. The treatment of choice was surgical., Conclusions: Upon the confirmation of a malformation, we emphasize the importance of performing a screening in order to search for other that could be associated., (Copyright: © 2018 Permanyer.)

Background: Airway hemangiomas are congenital neoplasms of low incidence. Its clinical presentation consists of obstruction of the upper airway with progressive dyspnea and stridor and the life of the patient at risk. Infantile hemangiomas have an incidence at birth of 2%, increasing to 9% at 12 months of life. Almost 60% of childhood hemangiomas affect the head and neck region. However, localization in the upper airway is not as frequent and it is only reported in 1.8% of patients with cutaneous hemangiomas. The traditional treatment of laryngeal hemangiomas has been the administration of systemic corticosteroids for long periods, endolaryngeal surgery with CO 2 laser, open surgery, tracheostomy or, recently, oral propranolol., Case Report: Five cases of subglottic hemangioma treated with systemic propranolol are presented. The therapeutic time of response with the satisfactory control of obstructive symptoms and assurance of the airway was evaluated. In these cases, propranolol was shown to be an effective and safe option for the treatment of laryngeal hemangiomas with a therapeutic response time of 48 to 72 hours., Conclusions: In recent years, the treatment with oral propranolol has become the first therapeutic option due to its high efficacy and safety profile., (Copyright: © 2018 Permanyer.)
