[A case of diverticular gastric heterotopy of the small intestine].

Report of an observation of a small intestine diverticulum with colic and gastric heterotopy in a seven year old girl. Unrecognized for many years, the lesion was at the origin of a severe digestive hemorrhage for which an urgent operation was necessary. A propos of this new enough case (30 published cases), characteristics of diverticular gastric heterotopy are remembered from diagnostic, nosologic and therapeutic point of view.

[Rare congenital aerodigestive fistulae].

Within the 1984 Symposium of the French Society of Pediatric Surgery, concerning tracheal and main bronchi malformations surgery, a synthesis is done from the observations of rare aerodigestive fistulae (esophageal atresia, H type tracheoesophageal fistula, esolaryngotracheal clefts excluded). The two types of aerodigestive fistulae reported in the literature are the communications with the esophagus and the biliary tract. 1) In the group of communications with the esophagus, the study concerned: fistulae associated with tracheal agenesia, with bad prognosis; fistulae associated with bronchopulmonary agenesia, with possible esophageal atresia; fistulae associated with bronchopulmonary foregut malformations.

[Review of the organogenesis of the respiratory system (excluding the pulmonary parenchyma)].

A simplified panorama of the different formation phases of the upper respiratory system (larynx, trachea, main bronchi) is presented. Chronologic evolution of organogenesis in embryologic phase and fetal phase is emphasized. Post-natal growing is also described.

[Value of the use of surgical endoscopy in chest surgery in children].

The authors emphasize the various possibilities of exploration of chest with the mediastinoscope, in a 11 patients series, aiming and reducing surgical parietal approach in infancy, while preserving the feasibility of the procedure. In the thoracic level: beyond the mediastinal approach by the transcervical pathway (mediastinoscopy), the principal application is the pleural cavity access (pleuroscopy) which was performed in seven 3 to 12 years old children. Pleuroscopy was realised through a small intercostal access permitting biopsy with a good visibility (pulmonary biopsy: 4 cases; lateral mediastinal tumor: 2 cases).
