    Notizen: Abstract. The RETAIN project (Radiological Examinations Transfer on an ATM Integrated Network) has aimed at testing videoconferencing and DICOM image transfers to get advice about difficult radiological cases over an asynchronous transfer mode (ATM)-based network, which affords a more comfortable interface than narrow-band networks and allows exchange of complete image series using the DICOM format of studies. For this purpose, an experimental ATM network was applied between six university hospitals in four different countries. An assessment of the functionalities of the system was performed by means of log-file analysis, video recording of the sessions and forms filled out by the participants at the end of each session. Questionnaires were answered by the users at the end of the project to bring out perspectives of utilisation and added value. We discussed 43 cases during 20 sessions. For technical or organisational problems, only 20 of the 36 planned sessions took place. The throughput over ATM (10.5 Mbit/s, 20 times faster than six ISDN B-channels) was adequate. Despite the experimental configuration of the network, the system was considered as satisfactory by all the physicians. In 72 % of the sessions, the expected result (answer to the question) was gained. By common consent, videoconferencing was unanimously regarded as a prominent tool in improving the interaction quality. Asynchronous transfer mode is an efficient method for fast transferring of radiologic examinations in DICOM format and for discussing them through high-quality videoconferencing.

    Beschreibung / Inhaltsverzeichnis: Résumé Les duplications digestives sont rares, liées dans leur forme tubulaire à un trouble de l'organogenèse datant de l'isolement de la notochorde lors de la 4e semaine de gestation: sa division aboutit à la formation d'un œsophage surnuméraire, se trouvant dans le médiastin postérieur, associé à des malformations vertébrales et relié à son extrémité distale au tractus digestif. Nous rapportons une observation de duplication œsophagienne à révélation anténatale, sous la forme d'une image échographique de tonalité liquidienne du médiastin postérieur, à l'origine d'un épanchement pleural important. A la lumière de l'anatomie, de l'embryogenèse, et de l'aspect échographique de la lésion, les autres diagnostics possibles sont discutés.
    Notizen: Summary Alimentary tract duplications are rare, linked in their tubular form with a disturbance of organogenesis at the time of the separation of the notochord during the 4th week of gestation. Its division leads to the formation of a supernumerary esophagus, situated in the posterior mediastinum, associated with vertebral malformations and connected at its distal extremity with the alimentary tract. We report a case of esophageal duplication revealed antenatally as an ultrasound image of fluid tonality in the posterior mediastinum, causing a major pleural effusion. The other diagnostic possibilities are discussed in terms of the anatomy, embryogenesis and ultrasonographic appearance of the lesion.
