Beyond well-known malformations, including tracheo-esophageal fistula and laryngo-tracheo-esophageal cleft, rarer anomalies have also been reported, including communicating bronchopulmonary foregut malformations and tracheal atresia. Herein, we describe a case of what we have called “esophageal trachea,” which, to our knowledge, has yet to be reported. A full-term neonate was born in our institution presenting with a foregut malformation involving both the middle esophagus and the distal trachea, which were found to be longitudinally merged into a common segment, 3 cm in length, located just above the carina and consisted of esophageal tissue without cartilaginous rings. At birth, the esophagus and trachea were surgically separated via right thoracotomy, the common segment kept on the tracheal side only, creating a residual long-gap esophageal atresia. T...

Four types of CBPFMs have been described, none of those contemplating a complete communication between the distal trachea and esophagus. Case Report This study reports a case of a full-term neonate presenting with a VACTERL association and a tracheoesophageal malformation characterized by the presence of a long common duct including both the middle esophagus and distal trachea, which consists in esophageal tissue, without any cartilaginous rings 3–4 cm above the carina. A few days after birth, the esophagus and trachea have been surgically separated, keeping the common duct on the tracheal side and creating a residual long-gap esophageal atresia (LGEA). The resulting severe tracheomalacia has been simultaneously treated by posterior splinting using an autologous pericardium patch, as well a...
Novel insights into the assessment of risk of upper gastrointestinal bleeding in decompensated cirrhotic children

Grade 2‐3 esophageal varices, red signs, and gastric varices are well‐known risk factors. However, the involvement of hemostatic factors remains controversial because of the rebalanced state of coagulation during cirrhosis.

The aim of this work was to investigate whether alterations of hepatic and systemic hemodynamics were correlated with cirrhosis severity in children. The impact of hemodynamic findings on surgical management in pediatric living donor liver transplantation (LT) was evaluated. Liver and systemic hemodynamics were studied prospectively in 52 children (median age, 1 year; 33 with biliary atresia [BA]). The hemodynamics of native liver were studied preoperatively by Doppler ultrasound and intraoperatively using invasive flowmetry. Portosystemic gradient was invasively measured. Systemic hemodynamics were studied preoperatively by Doppler transthoracic echocardiography and intraoperatively by using transpulmonary thermodilution. Hemodynamic parameters were correlated with Pediatric End-Stage Liver Disease (PELD) score and the histological degree of fibrosis (collagen proportionate area [CPA]). Cirrhosis was associated with a 60% reduction of pretransplant total liver flow (n 5 46; median, 36 mL/minute/100 g of liver) compared with noncirrhotic livers (n 5 6; median, 86 mL/minute/100 g; P 5 0.002). Total blood flow into the native liver was negatively correlated with PELD (P < 0.001) and liver CPA (P 5 0.005). Median portosystemic gradient was 14.5 mm Hg in children with cirrhosis and positively correlated with PELD (P < 0.001). Portal vein (PV) hypoplasia was observed mainly in children with BA (P 5 0.02). Systemic hemodynamics were not altered in our children with cirrhosis. Twenty-one children met the intraoperative criteria for PV reconstruction using a portoplasty technique during the LT procedure and had a smaller PV diameter at pretransplant Doppler ultrasound (median 5 3.4 mm; P < 0.001). Cirrhosis in children appears also as a hemodynamic disease of the liver, correlated with cirrhosis severity. Surgical technique for PV reconstruction during LT was adapted accordingly.

Materials and methods: From September 2013 to June 2014, a monocentric prospective study was performed on all children between 0 and 16 years-old, referred for chest X-ray for suspected pneumonia. Each child was examined by chest ultrasound by an examiner blinded to the chest X-ray. The presence or absence of areas of consolidation, their number and location were noted for each technique. The size of the consolidations identified only on ultrasound was compared with that of consolidations visible on both techniques. Results: 143 children (mean age 3 years; limits between 8 days and 14 years) were included. Ultrasound detected at least one area of consolidation in 44 out of 45 patients with positive X-rays. Of the 59 areas of consolidation on X-ray, ultrasound identified 54. In the 8 patients with negative X-ray, ultrasound revealed 17 areas of consolidation. The mean size of consolidations visible only on ultrasound was 9.4 mm; for consolidations visible on both techniques the mean size was 26 mm (p < 0.0001). The sensitivity and specificity of ultrasound were calculated at 98% and 92%. PPV and NPV were 85% and 99%, respectively. Conclusion: Chest ultrasound is a fast, non-ionizing and feasible technique. With its high negative predictive value, it can replace X-rays in order to exclude lung consolidation in children, thus reducing radiation exposure in this population.

Materiels et methodes Lors de l’echographie d’evaluation hepatique de routine et en l’absence de douleur abdominale, l’appendice ileo-caecal de 78 patients (âge 2 semaines a 41 ans, moyenne 14 ans et 2 mois) atteints de mucoviscidose a ete recherche. Le calibre antero-posterieur de l’appendice est mesure en coupe transversale suivant l’axe antero-posterieur. Resultats L’appendice ileo-caecal a ete visualise chez 66 patients (85 %) des cas. Chez 44 de ces 66 patients (67 %), le calibre de l’appendice depassait 6 mm (calibre moyen : 7,1 ± 2,3 mm), critere le plus communement admis pour le diagnostic echographique d’appendicite aigue. Le calibre moyen chez les patients pancreatiques suffisants (5,3 ± 1,8 mm) etait significativement plus petit (p = 0,006) que chez les patients necessitant une substitution enzymatique (7,4 ± 2,3 mm). Neanmoins, 40 % des patients pancreatiques suffisants (4/10) presentaient un calibre appendiculaire superieur a 6 mm pour 71 % (40/56) de patients sous substitution enzymatique. Conclusion Chez le patient atteint de mucoviscidose, le calibre de l’appendice ileo-caecal ne peut etre considere comme un critere d’appendicite aigue.

Materiels et methodes Analyse retrospective des OO reseques chirurgicalement dans une serie consecutive d’OO traites entre 1997 et 2007 par thermo-coagulation percutanee ou resection chirurgicale. Resultats Soixante-huit OO (48 hommes, 20 femmes ; âge moyen 21,1 ans) ont ete traites entre 1997 et 2007 (29 femurs, 13 vertebres, 8 tibias, 9 extremites, 9 autres). Douze resections chirurgicales ont ete realisees (7 vertebres, 5 extremites). Entre 1997 et 2001, 6 vertebres et 2 extremites ont ete operees. Entre 2002 et 2007, 1 vertebre, 2 extremites et 1 femur ont ete operes. Conclusion Les indications residuelles de la resection chirurgicale des OO ont evolue. Les localisations rachidiennes tendent a etre traitees par electrocoagulation. Le traitement des rares OO tres peripheriques reste parfois chirurgical suite aux difficultes de positionnement et au risque de necrose cutanee en cas de thermo-coagulation.
