    Notes: Summary In 28 patients with surgically proved loosening of hip-joint endoprostheses and 42 patients without loosening between 2 and 12 years after implantation and without clinical or radiological signs of loosening we performed clinical evaluation, and radiographs, a three-phase bone scan, and a 111indium-labeled leukocyte scan (ILLS). The sensitivity of radiographs in the group with loosening of hip-joint endoprostheses in the femoral as well as in the acetabular component was only about 50%, while the specificity was almost 100%. With a combination of radiographs and ILLS we reached a sensitivity in the acetabular component of 100% and in the femoral component of 88%, but specificities of only 57% in the acetabular component and 40% in the femoral component were found. We found that the ILLS is a very helpful method of examination to detect loosening of hip-joint arthroplasties in doubtful cases.

    Description / Table of Contents: Zusamenfassung 24 Patienten wurden 6 Monate bis 5 J. nach Gastrektomie und 2 Formen der Ersatzmagenbildung (17x Longmire-Gütgemann [LG], 7x Y-Roux [Y-R] klinisch und szintigraphisch nachuntersucht. Die Ersatzmagenfunktion zeigte keine signifikanten Unterschiede zwischen beiden Gruppen. Bei der hepato-biliären Sequenzszintigraphie fand sich jedoch eine deutlich verzögerte Reizantwort der Gallenblase bei Aufhebung der Duodenalpassage. Die Auswurffraktion war mit 16,2±4,9% (Y-R) gegenüber 46,8±24,9% (LG) deutlich verringert. Die ausgeprägte Fettresorptionsstörung beim Y-Roux-Ersatzmagen ist demnach durch eine Störung der Synchronisation von Speisenpassage und Gallengangsentleerung bei Aufhebung der Duodenalpassage bedingt.
    Notes: Summary Twenty-four patients were investigated clinically and scintigraphically 6 months to 5 years after gastrectomy; two different types of substitute stomach had been used (17x Longmire-Gütgemann [LG]; 7x Y-Roux [Y-R]. There was no significant difference in the substitute stomach function between the two groups. On hepatobiliary scintigraphy, delayed beginning of gallbladder contraction was detected in the Y-R substitute stomachs. Bile output was significantly lower in Y-R 616. (16.2%±4.9%) than in LG substitute stomachs (46.8%±24.9%). These results suggest that the defect in fat absorption after performing an Y-R substitute stomach is caused by a synchronization failure between chyme transit and bile flow in patients without a duodenal passage.
