    Description / Table of Contents:
    Zummmenfassung Die radiologische Darstellung von Krebsvorstufen am Verdauungstrakt wird diskutiert. Der Nachweis einer malignen Degeneration gelingt erst dann, wenn die malignen Prozesse sich makroskopisch von den zugrunde liegenden gutartigen Veränderungen unterscheiden. Die Röntgendiagnostik von Krebsvorstufen wird am Beispiel der chronischentzündlichen Veränderungen an Speiseröhre, Magen und Dickdarm und am Beispiel der Magen- und Colonpolypen dargestellt. Ausführlich wird auf die Beziehungen zwischen Magenuleus und -carcinom als Grundlage für deren radiologische Beurteilung eingegangen.
    Notes:
    Summary The problems of X-ray diagnostics of cancer precursors in the gastrointestinal tract are discussed. The demonstration of malignant degeneration is not possible until the malignant foci are distinguishable from the benign background by their macroscopic structure. The radiologic detection and evaluation of chronic inflammatory processes in esophagus, stomach and colon receive as much attention as the problem of polyps of the stomach and colon. The relations between stomach ulcer and cancer are discussed in detail.

    Description / Table of Contents:
    Résumé La cholangiopancréaticographie endoscopique rétrograde est indiquée dès lors que les données cliniques, biochimiques ou échographiques sont en faveur d'une éventuelle lithiase de la voie biliaire principale (VBP). Une étude r'etrospective de 599 patients traités pour maladie lithiasique a permis de développer un moyen de prédiction de lithiase de la VBP par analyse discriminante. Les variables les plus utiles pour prédire la présence d'une lithiase de la VBP étaient l'âge (ans), les valeurs de bilirubine (micromol/l), des ALAT (U/L) et des gamma GT (U/I). Il y a 22 faux positifs (3.7%) et 11 faux négatifs (1.8%) dans ce système de discrimination, comparés à 198 faux positifs (33.1%) et trois faux négatifs (0.5%) lorsque la discrimination était clinique. La correction par élimination d'une variable n'a pas changé les résultats. Chez un sous-groupe de 157 patients ayant eu une cholécystectomie, l'utilisation des seules données cliniques a produit 44.6% de faux positifs contre 4.5% de faux positifs en cas d'analyse discriminante. L'analyse discriminante aurait méconnu un patient avec une lithiase de la VBP. La sélection par l'analyse discriminante semble réduire la nécessité de CPRE sans augmenter la fréquence de lithiase de la VBP méconnue.
    Abstract:
    Resumen La colangiopancreatografia endoscópica retrógrada (CPER) ha sido utilizada en pacientes referidos para colecistectomía cuando la información clínica, los exámenes bioquímicos o la ultrasonografia indicaban la posible presencia de cálculos en el colédoco. Se hizo un estudio retrospectivo de 599 pacientes tratados por enfermedad biliar con el propósito de desarrollar un procedimiento de caracterización que permitiera predecir la presencia de cálculos en el colédoco por un proceso de análisis discriminado. Las variables seleccionadas para el análisis como mejores factores de predicción de cálculos en el colédoco fueron la edad (años), los niveles de bilirrubina (micromol/l), la ALAT (U/l) y la GT gama (U/I). La caracterización resultó positiva falsa en 22 casos (3.7%) y negativa falsa en 11 casos (1.8%), frente a 198 casos positivos falsos (33.1%) y 3 negativos falsos (0.5%) en la caracterización clinica. Las correccìones estadísticas no cambiaron los resultados. En un grupo de prueba de 157 pacientes sometidos a colecistectomia, la caracterización clínica fue positiva falsa en 44.6% de los pacientes, frente a 4.5% resultados positivos falsos al usar el procedimiento de análisis discriminado. El procedimiento de analisis discriminado habria fallado en 1 paciente con cálculos en el colédoco. La selección mediante el procedimiento de caracterización por análisis discriminado parece reducir la frecuencia de CPER en forma significativa sin aumentar el número de casos no detectados de cálculos en el colédoco.
    Notes:
    Abstract Endoscopic retrograde cholangiopancreatography (ERCP) has been used in patients referred for cholecystectomy when clinical information, biochemical values, or ultrasonography (clinical characterization) have indicated possible presence of common bile duct stones. A retropective study of 599 patients treated for gallstone disease was used to develop a characterization procedure for predicting common bile duct stones by a discriminant analysis procedure. The variables selected by the analysis as the best combination for CBDS prediction were age (years), the values of bilirubin (micromol/I), ALAT (U/I) and gamma GT (U/I). The characterization was false positive in 22 cases (3.7%) and false negative in 11 cases (1.8%), compared to 198 false positive cases (33.1%) and three false negative cases (0.5%) by the clincal characterization. A leaving-one-out correction did not change the results. In a test set of 157 cholecystectomy patients, clinical characterization was false positive in 44.6% of the patients, compared to 4.5% false positive results when using the discriminant analysis procedure. The discriminant analysis procedure would have missed one patient with common bile duct stones. Selection by the discriminant analysis characterization procedure seems to reduce the frequency of preoperative ERCP significantly without an inerease in undetected common bile duct stones.
