Notizen: Abstract Adenocarcinoma of the small intestine is uncommon. Due to this paucity and the lack of specificity of symptoms, patients are usually seen late in the course of their illness, when curative therapy, mainly represented by extensive surgical resection, is unlikely. The authors report a case of primary well-differentiated tubular adenocarcinoma (T4N0M0) arising in the duodenal limb of a reconstructed Billroth I gastroduodenostomy, 9 years after a distal gastrectomy for signet-ring cell carcinoma of the stomach (T4N0M0). Evidence for excluding the possibility of a recurrence of the primary gastric cancer was based on the different histologic pattern, the long disease-free interval, and other features of the second neoplasm. Relatively early diagnosis of the neoplasm, followed by curative surgical therapy was made possible by the early onset of the obstructive symptoms and the favorable anatomical location of the tumor.

Notizen: First, the three-dimensional elasto-plastic analyses of 1CT and 18 mm thick CCT specimens are carried out by using the finite element method, and the thickness effects of both specimens are studied. In elastic states, there is no significant difference between the CT and CCT specimen in the distribution of the J-integral along the straight or curved crack front. However, in elasto-plastic states, quite the contrary tendency is obtained in the distributions of J x and COD along the curved crack front for both specimens. Secondly, elasto-plastic analyses are carried out for CCT specimens of four kinds of thickness (B = 200, 18, 6 and 4 mm). The distributions of the J-integral along the crack front are obtained and compared. Finally, the availability of the JR value is examined, which is evaluated from the load versus displacement curve by using Rice's formula.
