    Notes: Abstract: We present the temperature dependence of elastic modes of Fe3-xZnxO4 with x = 0, x = 0.02 and x = 0.032. The c44 shear modes show a pronounced softening which can be normalized to a common behavior for all these substances. We can explain the softening with a bilinear coupling of the elastic strain to an order parameter linked to charge ordering processes. The other elastic modes (c11, c12 and the bulk modulus) do not show any softening. We present a symmetry analysis for the charge ordering model.

    Description / Table of Contents: Zusammenfassung Nach strenger Definition der benignen Magenausgangsstenose durch: verzögertes Erbrechen, Symptomwandel, Gewichtsverlust und intraoperative Prüfung mit Hegarstiften (〈 14) finden sich unter 619 operierten Ulcuspatienten 2,2% echte Stenosen. Operativ werden diese Patienten ausnahmslos durch SPV und digitale Magenausgangsdilatation über eine Gastrotomie behandelt. Bei Follow-up-Untersuchungen bis zu 10 Jahren ergab sich bei keinem Patienten die Indikation zur Reoperation. Alle Patienten zeigten Visick-Klassifikationen von I und II. Zusammen mit der SPV ergibt die digitale Magenausgangsdilatation bei Magenausgangsstenose gute klinische Ergebnisse bei Langzeit-Follow-up.
    Notes: Summary According to a strict definition of a benign gastric outlet obstruction i.e. delayed vomiting, changing of symptoms, weight loss and intraoperative test by Hegardilators (〈 14), 2.2% real stenoses among 619 operative treated duodenal ulcer patients were found. All patients were treated by SPV and digital dilatation of the stenosis through a gastrotomy. During up to a 10 year follow-up no reoperation was necessary. All patients showed Visick-classification of I and II. In conclusion SPV with digital dilatation showed good clinical results for patients with benign gastric outlet obstruction in long-term follow up.
