1/11. Gastrointestinal malformations in two infants born to women with hyperthyroidism untreated in the first trimester.We report two infants with gastrointestinal anomalies: one with esophageal atresia and tracheo-esophageal fistula and the other with biliary tree atresia, born to hyperthyroid women diagnosed and treated with methimazole after 14 weeks' gestation. Euthyroidism was documented in both infants. These cases raise the issue of whether untreated hyperthyroidism and not methimazole intake is the teratogen.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/11. tracheoesophageal fistula associated with perforated Meckel's diverticulum.Neonates with esophageal atresia and tracheoesophageal fistula (TEF) may present with respiratory distress. intubation and mechanical ventilation may force air from the tracheobronchial tree, through a distal fistula and into the gastrointestinal tract. We present a newborn with TEF who became moribund during mechanical ventilation. High ventilator pressures transmitted via the TEF caused over distention of the gastrointestinal tract and perforation of a Meckel's diverticulum.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/11. Multiple airway abnormalities in a patient with rothmund-thomson syndrome.rothmund-thomson syndrome (RTS) is a rare autosomal recessive disorder that is characterized by skin manifestations, juvenile cataracts, and extracutaneous manifestations. The presence of congenital airway abnormalities has not previously been documented in rothmund-thomson syndrome. We report the case of a child with rothmund-thomson syndrome suffering from multiple airway abnormalities. Our case highlights the importance of suspecting multiple airway abnormalities in any child with respiratory distress with other systemic anomalies. This necessitates meticulous anatomical and dynamic examination of the laryngotracheo-broncheal tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/11. Multidetector-row computed tomography three-dimensional volume reformatted 'transparency' images to define an upper pouch fistula in oesophageal atresia.Oesophageal atresia (OA) is an important congenital malformation in which prompt diagnosis and appropriate management can significantly improve outcome. The surgical approach to repair of OA and associated tracheo-oesophageal fistulae (TOF) depends upon correct evaluation of the tracheobronchial tree. Three-dimensional imaging of the tracheobronchial tree using CT data to produce shaded surface displays and virtual bronchoscopy has been reported in paediatric and neonatal patients with OA and TOF and is described as accurate and helpful, non-invasively facilitating the appreciation of complex anatomy prior to surgery. We describe the technique of reconstructing 3D volume-reformatted 'transparency' images using insufflated air as a negative contrast medium. This technique is fast, accurate and produces high-quality images that are easy to reproduce.- - - - - - - - - - ranking = 2keywords = tree (Clic here for more details about this article) |
5/11. esophageal atresia, distal tracheoesophageal fistula, and an air shunt that compromised mechanical ventilation.Infants with esophageal atresia and a distal tracheoesophageal fistula are predisposed to respiratory failure on the basis of prematurity, respiratory distress syndrome, aspiration of saliva, and reflux of gastric contents into the tracheobronchial tree. thoracotomy and primary repair may be delayed to allow time for complete evaluation of the infant and respiratory stabilization. Poorly compliant lungs and a large distal fistula can result in selective passage of ventilatory gases into the gastrointestinal tract with resultant hypercarbia. Fogarty balloon occlusion of the distal esophageal segment halts this air shunt and facilitates effective mechanical ventilation.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/11. Management of esophageal atresia and tracheoesophageal fistula in the neonate with severe respiratory distress syndrome.In a 10-year period, 22 neonates with esophageal atresia (EA) and tracheoesophageal fistula (TEF) required high pressure ventilatory support soon after birth because of respiratory distress syndrome (RDS). Eleven of the 22 or 50% survived overall, but if the 5 patients who died before definitive surgical repair could be attempted are excluded, 11 of 17 or 65% survived. More importantly, 4 of 7 (57%) patients who had gastrostomy performed first survived while 7 of 10 (70%) who had fistula ligation performed first survived. The difficulties with intraoperative management of those who had gastrostomy performed first were even more impressive. Our experience leads us to conclude that patients with EA and TEF with severe RDS who require high pressure ventilation preoperatively represent a group of patients who require special consideration. The danger to such patients with increased pulmonary resistance is not gastric distention but sudden loss of intragastric pressure. In the presence of poor lung compliance, the upper gastrointestinal tract functions in continuity with the tracheobronchial tree. A sudden loss of intragastric pressure, as with placement of a gastrostomy tube, results in an acute loss of effective ventilating pressure. resuscitation of such a patient is not possible until leakage from the esophagus is controlled by ligation of the fistula or transabdominal occlusion of the distal esophagus. Placement of a Fogarty catheter into the fistula via a bronchoscope is effective but may not be feasible in every case. Early thoracotomy and ligation of the fistula in patients with progressive RDS provides immediate improvement in ventilatory efficiency and relief of gastric distention.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/11. Management of benign fistulae between Zenker's diverticulum and the trachea.Cases of acquired benign fistula of the respiratory tree and esophagus have been reported in relation to mycobacterium tuberculosis and trauma. Fistula formation between the trachea and a Zenker's diverticulum is a similar type of condition in which nutritional and immunological deficiencies can rapidly result in further complications which may mimic a malignancy. Spontaneous fistula formation and vocal cord paralysis may result. Surgical management of this condition includes interposing viable muscle between the esophagus and trachea at the repair site.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
8/11. Tracheal compression as a cause of respiratory symptoms after repair of oesophageal atresia.A case of tracheal compression in an infant after repair of a tracheo-oesophageal fistula and oesophageal atresia is reported. Tracheopexy completely relieved the symptoms of apnoeic attacks, cyanosis, and convulsions. We suggest that tracheal compression in infants and children with repaired oesophgeal atresia can not only cause life-threatening attacks but also be responsible for recurrent chest infections. All infants and children with signs and symptoms of tracheal compression as shown by the presence of a barking type of cough, recurrent chest infections, or persistent mild respiratory symptoms should be referred for thorough investigation of the tracheobronchial tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
9/11. Prevention of gastroesophageal reflux using Nissen fundoplication in the staged repair of esophageal atresia with distal tracheoesophageal fistula.To prevent the reflux of gastric contents into the bronchial tree through the tracheoesophageal fistula in patients with esophageal atresia with tracheoesophageal fistula, Nissen fundoplication was performed in the first-stage repair of staged operations. After elimination of the pulmonary complication, a correction of esophageal atresia and tracheoesophageal fistula was successfully performed through the extrapleural route at the age of 16 days. Thus, because Nissen fundoplication is simple to perform and effective in preventing gastroesophageal reflux, this procedure is considered to be useful in the staged repair of esophageal atresia with tracheoesophageal fistula.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/11. Unusual manifestation of tuberculosis: TE fistula.Fistulas between the tracheobronchial tree and the esophagus (TE fistula) caused by tuberculosis are rare; usually they are associated with readily apparent pulmonary and/or mediastinal infection, and require surgical management. The patient we describe presented with a TE fistula as the only manifestation of active tuberculosis. This case represents the first report of successful nonsurgical treatment of tuberculous TE fistulas.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
