    Notes: Abstract Objective The purpose of this trial was to clarify the effets of intravenous ketamine at anaesthetic and sub-anaesthetic dosages on gastrointestinal motility. Design 20 beagles (group 1: 3 mg/ketamine/kg/h,n=10; group 2: 30 mg ketamine/kg/h,n=10), were investigated. Gastric emptying (nuclide gastric emptying studies, liquid and semi-solid test meal), intestinal transit time (Hydrogen breath test with lactulose) and intestinal motor function (perfusion manometry with 8 measuring ports) were determned. As a control condition, the tests were performed on all dogs in the two groups during infusion of physiological saline solution. Results No significant differences in the motility patterns were present between 3 mg ketamine/kg/h and the control condition. For group 2, a moderately significant (p〈0.05) increase in the interdigestive motility index was observed for 30 mg k ketamine/kg/h. However, this did not change the transit criteria. There was no significant difference between ketamine and control condition tests with regard to cycle and phase lengths or the propagation rate of the activity front. Conclusions We conclude that ketamine provokes no basic changes in gastrointestinal motility, at either sub-anaesthetic doses. It can there-fore be used to advantage in the continuous postoperative analgesia of intensive care patients, where repeated interventions are necessary and no cardiopulmonary contraindications are present.

    Notes: Abstract. Fluorine-18 labelled fluoromisonidazole ([18F]FMISO) has been shown to accumulate in hypoxic tissue in inverse proportion to tissue oxygenation. In order to evaluate the potential of [18F]FMISO as a possible positron emission tomography (PET) tracer for imaging of liver tissue hypoxia, we measured the [18F]FMISO uptake in 13 domestic pigs using dynamic PET scanning. Hypoxia was induced by segmental arterial hepatic occlusion. During the experimental procedure the fractional concentration of inspired oxygen (FiO2) was set to 0.67 in group A (n=6) and to 0.21 in group B (n=7) animals. Before and after arterial occlusion, the partial pressure of O2 in tissue (TPO2) and the arterial blood flow were determined in normal flow and flow-impaired liver segments. Standardised uptake values [SUV=kBq tissue (in g) / body weight (in kg) × injected dose (in kBq)] for [18F]FMISO were calculated from PET images obtained 3 hours after injection of about 10 MBq/kg body weight [18F]FMISO. Immediately before PET scanning, the mean arterial blood flow was significantly decreased in arterially occluded segments [group A: 0.41 (0.32–0.52); group B: 0.24 (0.16–0.33) ml min–1 g–1] compared with normal flow segments [group A: 1.05 (0.76–1.46); group B: 1.14 (0.83–1.57) ml min–1 g–1; geometric mean (95% confidence limits); P〈0.001 for both groups]. After PET scanning, the TPO2 of occluded segments (group A: 5.1 (4.1–6.4); group B: 3.5 (2.6–4.9) mmHg] was significantly decreased compared with normal flow segments [group A: 26.4 (21.2–33.0); group B: 18.2 (13.3–25.1) mmHg; P〈0.001 for both groups]. During the 3-h PET scan, the mean [18F]FMISO SUV determined in occluded segments increased significantly to 3.84 (3.12–4.72) in group A and 5.7 (4.71–6.9) in group B, while the SUV remained unchanged in corresponding normal liver tissue [group A: 1.4 (1.14–1.71); group B: 1.31 (1.09–1.57); P〈0.001 for both groups]. Regardless of ventilation conditions, a significant inverse exponential relationship was found between the TPO2 and the [18F]FMISO SUV (r 2=0.88, P〈0.001). Our results suggest that because tracer delivery to hypoxic tissues was maintained by the portal circulation, the [18F]FMISO accumulation in the liver was found to be directly related to the severity of tissue hypoxia. Thus, [18F]FMISO PET allows in vivo quantification of pig liver hypoxia using simple SUV analysis as long as tracer delivery is not critically reduced.

    Notes: Abstract. The biological fate of allogenic bone grafts in the acetabular cavity and their metabolic activity after acetabular augmentation is uncertain but is most important for the stability of hip implants after hip revision arthroplasty. The aim of this study was to quantify regional bone metabolism after hip replacement operations. Dynamic [18F]fluoride ion positron emission tomography (PET) was used to investigate the metabolic activity of acetabular allogenic bone grafts and genuine bone, either 3–6 weeks (short-term group, n = 9) or 5 months to 9 years (long-term group, n = 10) after hip revision arthroplasty. Applying a three-compartment model, the fluoride influx constant was calculated from individually fitted rate constants (K nlf) and by Patlak graphical analysis (K pat). The results were compared with genuine cancellous and cortical acetabular bone of contralateral hips without surgical trauma (n = 7). In genuine cortical bone, K nlf was significantly increased in short- (+140.9%) and long-term (+100.0%) groups compared with contralateral hips. Allogenic bone grafts were characterised by a significantly increased K nlf in the short-term group (+190.9%) compared with contralateral hips, but decreased almost to the baseline levels of contralateral hips (+45.5%) in the long-term. Values of K nlf cor-related with the rate constant K 1 in genuine (r = 0.89, P〈0.001) and allogenic bone regions (r = 0.79, P〈0.001), indicating a coupling between bone blood flow and bone metabolism in genuine bone as well as allogenic bone grafts. K pat values were highly correlated with K nlf measurements in all regions. In conclusion, [18F]fluoride ion PET revealed the presence of an increased host bone formation in allogenic bone grafts early after hip revision arthroplasty. In contrast to genuine cortical bone, allogenic bone graft metabolism decreased over time, possibly due to a reduced ability to respond to the same extent as genuine bone to elevated metabolic demands after surgery.

    Notes: Abstract Six European nuclear medicine centres per formed immunoscintigraphy first retrospectively in 34 patients using indium-111-labelled carcinoembryonic antigen (CEA)-specific and/or 19-9 F(ab')2 fragments. Results for sensitivity and specificity in tumour sites were 94% and 87%, respectively, for the pelvis and 73% and 100% for the extrahepatic abdomen. A second prospective series concerned 58 other patients previously operated on for colorectal adenocarcinoma (27 colon, 31 rectum). Two-thirds of these patients had a suspected recurrence signalled by an isolated rise in tumour markers, and 46 patients examined by immunoscintigraphy, X-ray computed tomography and ultrasonography were found to have a recurrence (a total of 62 tumour sites). Sensitivity and specificity with immunoscintigraphy were 90% and 97%, respectively, for the pelvis and 62% and 95% for the extrahepatic abdomen. For 29 patients injected with CEA-specific fragments, sensitivity was 90% and specificity 94% for the pelvis. For 25 patients injected with 19-9 fragments, pelvic sensitivity and specificity were 80% and 100%, respectively, whereas sensitivity for the extrahepatic abdomen was only 29% since several cases of peritoneal carcinosis were not visualized. In the prospective series, comparison of the three imaging techniques for all tumour sites (including liver and in 5 cases thorax) gave a sensitivity and specificity of 82% and 91 %, respectively, for immunoscintigraphy, 52% and 95% for X-ray computed tomography and 59% and 100% for ultrasonography. These results thus confirm the advantage of using111In-labelled CEA-specific or 19-9 to visualize and localize recurrences of colorectal cancer.

    Description / Table of Contents: Summary Although the detection of pancreatic carcinoma has been considerably improved by recently developed imaging procedures, differential diagnosis between cancer and benign tumor masses, as well as lymph node staging, is still difficult. In vivo evaluation of regional glucose metabolism by means of positron emission tomography (PET) and fluorine-18-labelled fluorodeoxyglucose (FDG) is a new approach utilizing metabolic instead of morphological tumor properties for diagnosis. Patients and methods: A total of 85 patients with suspected pancreatic carcinoma were investigated by FDG-PET prior to surgery. Static PET scans were evaluated visually as well as quantitatively, taking increased FDG uptake as a sign of malignancy. PET results were correlated with intraoperative findings and histopathology of surgical specimens. Results: Forty-seven out of 55 (85 %) malignant tumors and 23 out of 30 (77 %) benign lesions were correctly classified by PET. Lymph node metastases were present in 31 patients, 19 of them (61 %) positive in PET. In 7 our of 13 (54 %) patients with liver metastases, PET detected hypermetabolic lesions. False-negative findings were mainly due to disturbance of glucose metabolism in diabetic patients, while most false-positive results could be attributed to acute inflammatory lesions in chronic pancreatitis. Conclusions: Our results indicate that classification of pancreatic masses can be improved by use of FDG-PET, which might lead to a reduction of unnecessary laparotomies in patients with benign or incurable disease.
    Notes: Zusammenfassung Trotz methodischer Verbesserungen in der Diagnostik des Pankreaskarzinoms ist die Differentialdiagnose pankreatischer Raumforderungen bei bestehender chronischer Pankreatitis sowie der Nachweis etwaiger Lymphknotenmetastasen bislang nur unvollständig gelöst. Die Bestimmung des regionalen Glukosestoffwechsels mit Hilfe der Positronenemissionstomographie (PET) und Fluor-18-markierter Fluordesoxyglukose (FDG) stellt einen neuen diagnostischen Ansatz dar, der nicht auf dem Nachweis morphologischer sondern metabolischer Tumorcharakteristika beruht. Bei 85 Patienten mit vermutetem Pankreaskarzinom wurde präoperativ eine FDG-PET durchgeführt und der Befund mit der histopathologischen Aufarbeitung des Operationspräparats verglichen. Von 55 malignen Tumoren konnten 47 anhand ihres Hypermetabolismus korrekt klassifiziert werden (85 %), 23 von 30 benignen Tumoren (77 %) wiesen keine Stoffwechselsteigerung auf (richtig-negativ). In der Ausbreitungsdiagnostik zeigte PET in 19 von 31 Fällen (61 %) korrekt das Vorliegen regionaler Lymphknotenmetastasen, in 7 von 13 Fällen (54 %) eine Lebermetastasierung an. Falsch negative Befunde fanden sch bei Diabetikern (5 von 8 unentdeckten Primärtumoren) während falsch positive Ergebnisse mehrheitlich (4 von 7) auf akut entzündliche Veränderungen bei chronischer Pankreatitis zurückzuführen waren. Diese Ergebnisse belegen, daß durch die FDG-PET eine Verbesserung der Diagnostik unklarer pankreatischer Raumforderungen erreicht werden kann, die zu einer Reduktion unnötiger Laparatomien beitragen könnte.

    Description / Table of Contents: Abstract Background. Renal studies have a long tradition in nuclear medicine and are available for routine use for more than 30 years. Their high clinical acceptance is mainly based upon the fact that they allow for quantitative evaluation of different functional parameters such as glomerular filtration, effective renal plasma flow, or postrenal transport. The used methods are validated by experimental as well as numerous clinical studies and are performed throughout the world in a highly standardized way. Indications. Indications are verification/exclusion of a disturbed renal function, detection or evaluation of renal artery stenosis, and differential diagnosis of urinary tract obstruction. Further diagnostic improvement might be achieved by use of positron emission tomography which has the potential for absolute quantification of physiological parameters such as renal blood flow in ml · min−1· 100g−1 tissue.
    Notes: Zusammenfassung Hintergrund. Untersuchungen der Nieren zählen zu den ältesten und am besten etablierten diagnostischen Anwendungen der Nuklearmedizin. Begründet ist dies durch die Verfügbarkeit nierenspezifischer Radiopharmaka, die eine Quantifizierung physiologischer Funktionsparameter (glomeruläre Filtrationsrate, effektiver renaler Plasmafluss) und luminaler Transportvorgänge (Harnabfluss zur Blase) zulassen. Die hierzu eingesetzten Methoden sind in Jahrzehnten klinischer Anwendung validiert und stehen weltweit in standardisierter Form zur Verfügung. Indikationen. Als wichtigste Indikationen sind derzeit der Nachweis/Ausschluss von Nierenschädigungen, die Differenzierung postrenaler Harnabflussstörungen und die funktionelle Bewertung von Nierenarterienstenosen anzusehen. Aktuelle Entwicklungen unter Einbeziehung der Positronenemissionstomographie deuten eine weitere Verbesserung der Quantifizierungsmöglichkeiten an (z. B. renaler Blutfluss in ml min−1 100g−1), die vorerst allerdings wissenschaftlichen Fragestellungen vorbehalten bleibt.

    Description / Table of Contents: Zusammenfassung In einer prospektiven Studie wurde bei 32 Patienten mit primären kolorektalen Tumoren eine präoperative Radioimmunszintigraphie mit dam CEA-Antikörper BW 431/26 markiert mit entweder 131J (Gruppe 1, n = 17) oder 99Tc (Gruppe 2, n = 15) durchgeführt. Als Modell für die intraoperative Radioimmunszintimetrie folgte unmittelbar postoperativ eine Präparatszintigraphie mit Markierung aller positiven Lymphknoten. Die Ergebnisse wurden mit den Daten der präoperativen Diagnostik (CT, MR, Endosonographie) verglichen und histologisch Bowie immunhistochemisch kontrolliert. Die Analyse (Sensitivität, Spezifität) erfaßte die Parameter: Untersuchungsart und -zeitpunkt, Radionuklidtyp, Lymphknotengröße and CEA-Serumspiegel. Die Präparatszintigraphie zeigte bei Verwendung des 131J-Antikörpers die besten Ergebnisse in der Lymphknotendiagnostik (Sensitivität: 1, Spezifität: 0,57) und war allen anderen Verfahren überlegen. Die Spezifität konnte bei einer Untersuchung am 6. bis 8. Tag auf 1 angehoben warden. Kleine (〈 1 cm) Lymphknotenmetastasen wurden präparatszintigraphisch am exaktesten diagnostiziert (Sensitivität: 1, Spezifität: 0,91). Immunhistochemisch konnte eine gute Korrelation von szintigraphischer Positivität und CEA-Exprimierung nachgewiesen werden, während der Serum- CEA-Spiegel keinen Einfluß auf die Ergebnisse hatte. Wir folgern, daß die intraoperative Radioimmunszintimetrie einen Beitrag zur Verbesserung der Radikalität bei der Resektion kolorektaler Tumoren leisten kann. Die besten Ergebnisse werden mit einer 131J-Markierung und der Applikation des Radionuklid-Antikörper-Komplexes am 6. bis 8. präoperativen Tag erreicht.
    Notes: Abstract In a prospective study 32 patients with primary colorectal carcinomas were studied by means of radioimmunoscintigraphy with the anticarcinoembryonic antigen monoclonal antibody BW 431/26 labelled with either 131I (group 1, n = 17) or 99Tc (group 2, n = 15). Scintigraphy of the resected specimen was used as a model for intraoperative radioimmunoscintimetry, and all positive lymph nodes were marked during the investigation. The results were compared with the data yielded by preoperative investigations (CT, MR, endosonography) and checked by histology and immunohistochemistry. The analysis (sensitivity, specificity) included: type of investigation, time interval from antigen application, type of radionuclide, size of lymph nodes investigated, and serum level of CEA. 131I-Scintigraphy of the resected specimen gave the best results in the detection of lymph node metastases (sensitivity 1, specificity 0.57) and was superior to all other diagnostic procedures. When the investigation was performed 6–8 days after administration of the antibody the specificity improved to 1. The best results (sensitivity 1, specificity 0.91) were achieved in small (〈 1 cm) lymph node metastases. A good correlation between scintigraphic diagnosis and immunohistochemical CEA detection was confirmed. Serum levels of CEA had no influence on the scintigraphic results. We conclude that intraoperative radioimmunodetection of lymph node metastases may improve the radicality in the resection of colorectal tumors. The best results are achieved with 131I-labelling and with application of the antibody 6–8 days before the operation.

    Description / Table of Contents: Zusammenfassung Zur Klärung der intestinalen Motilitätsbedingungen nach Gastrektomie wurde eine tierexperimentelle Studie durchgeführt. Acht männliche Beaglehunde (22,5–27,2kg) wurden gastrektomiert und mit einer standardisierten Jejunuminterposition (JI, n = 4) oder Roux-Y-Ersatzmagenbildung (RY, n = 4) rekonstruiert. Als Meßmethoden kamen die 8-Kanalperfusionsmanometrie, nuklearmedizinische Entleerungsstudien der Ersatzmägen und der H2-Atemtest mit Laktulose zur intestinalen Passagezeitbestimmung zum Einsatz. Die präoperativen Untersuchungen der Versuchstiere dienten als Kontrollen (K). Zur Erfassung evtl. auftretender Adaptationsprozesse wurden die postoperativen Untersuchungen in der 6.–8., 12.–14. und 24.–30. Woche durchgeführt. Die Ersatzmagenentleerung war bei beiden Rekonstruktionsformen nach einem halben Jahr deutlich beschleunigt (T50:5,8–8,1min) und, im Gegensatz zu den Kontrollen, nach einer kalorischen Testmahlzeit eher schneller als nach einer akalorischen. Die intestinale Transitzeit zeigte frühpostoperativ deutlich beschleunigte Werte, wies jedoch im weiteren Verlauf eine signifikante Verlangsamung auf die bei JI deutlich ausgeprägter war (K: 101 ± 26min, JI: 104 ± 18,2min, RY: 71,3 ± 13,4min; p 〈 0,01). Als Erklärung konnten pathologische Motilitätsmuster by RY indentifiziert werden die insbesondere eine markante Erhöhung der Motilitätsindex (p 〈 0,0001) im proximalen Jejunum und die Dissoziation zwischen Ersatzmagen- und duodenaler Motilität beinhalteten. Die Beobachtungen legen die Vermutung nahe, daß Duodenum und Ersatzmagen nach RY-Rekonsturktion 2 unabhängig voneinander agierende de Schrittmacher generieren, die beide die unteren Dünndarmabschnitte beeinflussen. Wir folgern, daß Motilitätsphänomene in erheblichem Umfang die postoperative Funktion der Ersatzmagenbildung nach Gastrektomie beeinflussen, und daß die postoperative Funktion mehr von der Motorik des gesamten Intestinaltraktes abhängt als von den Parameters der Ersatzmagenentleerung. Die Jejunuminterposition scheint im Hinblick auf die intestinale Motilität Vorteile gegenüber der Roux-Y-Rekonstruktion zu haben.
    Notes: Abstract An experimental study in animals was conducted to evaluate the motility patterns after total gastrectomy. Eight male beagle dogs (22.5–27.2kg) had total gastrectomy with standardized designs of gastric substitution: (1) jejunal interposition (JI, n=4); (2) Rouxen-Y reconstruction (RY, n=4). Motility patterns were detected with perfused manometry (eight measuring ports), sequential scintigraphic emptying studies of the gastric substitute (caloric and acaloric medium viscosity test meals), and a hydrogen breath test with lactulose. The preoperative studies of the same individuals served as controls (CO). To detect postgastrectomy adaptation processes the postoperative studies were conducted 6–8, 12–14, and 24–30 weeks after total gastrectomy. The emptying of the gastric substitutes was markedly accelerated compared with CO after 6 months (T50: 5.8–8.1 min). In contrast to the preoperative studies, caloric test meals caused a trend to increase the velocity of the evacuation. The intestinal transit time was accelerated too in the weeks immediately, after the operation. In JI dogs intestinal transit was then markedly slowed and to a highly significant difference after 6 months compared to RY animals (CO: 101±26min, JI: 104±18.2min, RY: 71.3±13.4min; p〈0.01). Pathologic motility patterns could be identified as the cause of this observations: RY dogs showed a marked increase of the intestinal motility index in the proximal jejunum (p〈0.0001) and a dissociation between the motility patterns of the duodenum and the gastric substitute. The observations gave rise for the supposition that this parts of the small bowel might generate two independent pacemarkers that both influence the lower intestinal parts after RY reconstruction. We conclude that the motility patterns of the entire small bowel highly influence the postoperative function of reconstruction procedures after total gastrectomy. The emptying velocity of the jejunal gastric substitute does not seem to have a major influence on the postoperative results. According to motility patterns jejunal interposition has a better outcome than Roux-en-Y reconstruction.
