[An abdominal tumor of unusual nature. Synovial cyst in the iliopsoas bursa]. / A propos d'une tumeur de l'abdomen de nature exceptionnelle. Kyste synovial de la région iliaque développé de la bourse du psoas.

The authors report a case of tumour of the right iliac region in a 14 years old girl, disclosed by a light traumatism, without appreciable antecedents, nor locomotor disfunction. Ultrasonography and computed tomography showed its cystic constitution. Surgically, there was a synovial cyst of the ilioinguinal area, cyst of the iliopsoas bursa, with a hip joint communication. It was resected and a partial recurrence occurred, corrected surgically three years later. A recent MRI showed the spontaneous development of a same cyst on the left side, asymptomatic at all. A non exhaustive survey of literature confirmed the iliopsoas synovial bursa is uncommonly pathologic, but a constant natural formation in man. Pathology occurs only in over sixty years old adults. This case seems to be the first pediatric case. The cyst of the psoas bursa is generally revealed by an inguinal swelling; abdominal growing is rare. Imaging with ultrasonography, computed tomography and RMI such as in this case, showed the cyst issued between the coxofemoral joint and the iliac psoas terminal tendon. It can grow in a retroperitoneal way. Pathogenic hypothesis are debated. In this bilateral case, etiology evoke an anatomic anomaly, in relation a joint communication.

[A case of diverticular gastric heterotopy of the small intestine]. / A propos d'un cas d'hétérotopie gastrique diverticulaire de l'intestin grêle.

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. Their individualization with regard to Meckel's diverticulum and remainders of omphalo-mesenteric canal is emphasized.

[Review of the organogenesis of the respiratory system (excluding the pulmonary parenchyma)]. / Rappel de l'organogénèse de l'appareil respiratoire (parenchyme pulmonaire exclu).

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. A classification of malformations of the upper respiratory system is done, based on topographic data. The mechanism of genesis of the malformations remains of hypothetical value.

[Rare congenital aerodigestive fistulae]. / Les fistules aéro-digestives congénitales rares.

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. 2) The quite tracheobiliary fistulae, setting up the second group of aerodigestive fistulae, are reviewed. This report analyse the etiologic, anatomic, clinic and therapeutic data of every one malformations.

[Value of the use of surgical endoscopy in chest surgery in children]. / Intérêt de l'utilisation d'une "endoscopie chirurgicale" en chirurgie thoracique chez l'enfant.

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). A cloisonned pyopneumothorax drainage was performed once easily managed. Mediastinoscopy was used likewise in 3 cases of transcervical thymectomy (myasthenia gravis or thymic hyperplasia), permitting effective visual field to control quality of exeresis. This "surgical endoscopy" procedure offers so food indications in Pediatric Surgery, more especially as not any complication was observed.
