    Description / Table of Contents: Résumé Dans l'évaluation pré-opératoire du cancer du rectum au moyen d'une tomographie computérisée, une nouvelle technique de distension complète du rectum à l'aide d'un lavement d'eau a été comparée avec la technique standard de tomographie computérisée au cours d'une étude non randomisée. Cent vingt et un patient ont été inclus dans l'étude. Cinquante sept ont subi un lavement à l'eau et 64 ont subi un CT-Scan standard. L'étendue de l'affection a été établie selon des critères stricts et comparés avec le résultat de l'examen anatomo-pathologique de la pièce opératoire. Le CT-Scan avec lavement à l'eau était significativement plus précis que le CT-Scan standard: 84,2% contre 62,5% (Kappa: 0.56 vs 0,33: Kappa pondéré: 0,93 vs 0,84). Le gain diagnostique était particulièrement prononcé dans l'identification de l'invasion pariétale en-deçà ou au-delà de la couche musculaire (94,7 vs 61). L'augmentation de sensibilité était de 33,7% (CL95: 17–49;P〈0,0001). Les résultats montrent que la technique avec lavement à l'eau devrait remplacer le CT-Scan standard dans le staging du cancer du rectum et peut représenter une alternative á l'échographie endo-rectale.
    Notes: Abstract A new technique in the preoperative staging computed tomography of rectal cancer using a water enema to promote full distension of the rectum was compared with standard CT in a non-randomised blind study. One hundred and twenty-one patients were enrolled. There were 57 in the water enema CT group and 64 in the standard group. The stage of the disease was assessed following strict criteria and tested against the pathological examination of the resected specimen. Water enema CT was significantly more accurate than standard CT with an accuracy of 84.2% vs. 62.5% (Kappa: 0.56 vs. 0.33: Kappa Weighted: 0.93 vs. 0.84). The diagnostic gain was mainly evident in the identification of rectal wall invasion within or beyond the muscle layer (94.7 vs. 61). The increased accuracy was 33.7% (CL95: 17–39;P〈0.001). The results indicate that water enema CT should replace CT for staging rectal cancer and may offer an alternative to endorectal ultrasound.

    Notes: Abstract Background: To increase the value of ultrasound in the staging of stenotic rectal carcinoma. Methods: Water enema transvaginal ultrasound (WE-TVUS) was performed in 21 consecutive female patients with severely stenotic rectal tumor (adenocarcinoma histologically proved) who were selected on the basis of clinical and double-contrast barium enema study. All patients underwent surgery, and histopathologic correlation was possible. Results: Rectal tumors were well demonstrated in all cases, and a good correlation between perirectal neoplastic infiltration, and lymph node involvement at WE-TVUS and histologic data were observed. Compared with histologic results, WE-TVUS correctly staged 19 of 21 tumors (overall accuracy = 90%); one case was understaged (T4 as T3) and one case was overstaged (T3 as T4). In the detection of lymph node involvement, the sensitivity was 50% and specificity was 78%. Conclusion: WE-TVUS is a potentially valuable technique for defining the local extension of severely stenotic rectal tumors in women.

    Notes: Abstract. Computed tomography is an accurate method of identifying the various types of abdominal wall hernias, especially if they are clinically occult, and of distinguishing them from other diseases such as hematomas, abscesses and neoplasia. In this study we examined the CT images of 94 patients affected by abdominal wall hernias observed over a period of 6 years. Computed tomography clearly demonstrates the anatomical site of the hernial sac, the content and any occlusive bowel complications due to incarceration or strangulation. Clinical diagnosis of external hernias is particularly difficult in obese patients or in those with laparotic scars. In these cases abdominal imaging is essential for a correct preoperative diagnosis and to determine the most effective treatment.

    Notes: Abstract. The MR imaging appearance of a duodenal duplication cyst is reported. MR imaging confirmed the diagnosis suggested by ultrasound and CT scans. Fat-suppressed MR imaging before and after oral administration of the positive contrast agent Gd-DTPA was able to define tissue planes between the lesion and adjacent structures, such as the head of the pancreas, providing useful information for an accurate surgical approach. To our knowledge this is the first reported case of a duodenal duplication cyst in an adult demonstrated by MR imaging.

    Notes: Abstract. The aim of the study was to verify the efficacy of ultrasonography (US) in evaluating the morphology of normal trochlea, especially the sulcus angle and the trochlear depth, in comparison with computed tomography (CT) (gold standard). The knees of 11 asymptomatic volunteers were subjected to US and CT evaluation of the same section planes and the results were compared. For statistical evaluation Spearman's correlation coefficient analysis was used. A statistically significant correlation was found between the two diagnostic procedures (sulcus angle: r = 0.820; trochlear depth: r = 0.802; Spearman's correlation coefficient) and the intra-observer variability for the US measurements (sulcus angle: r = 0.966; trochlear depth: r = 0.914; Spearman's correlation coefficient). The mean value of sulcus angle and trochlear depth was 132 ° and 5.6 mm, respectively, similar to those reported in the literature. We conclude that evaluation by US of both sulcus angle and trochlear depth is as reproducible and sensitive as that performed with CT.

    Notes: Summary An echographic study of Tietze's syndrome was carried out. Three patients with clinical evidence of Tietze's syndrome were examined. Ten normal volunteers were studied as controls. In Tietze's syndrome a dishomogeneous increase of the echogenicity in pathological cartilage and an increased thickness vs. the oposite normal side were observed. A moderate thickness and a decreased echogenicity of surrounding soft tissues was observed in one case.

    Notes: Summary We studied an echographic technique by which precise reproducible measurements of articular cartilage thickness of the knee is possible. Two groups of individuals were studied: a group of 18 patients with gonarthrosis and a control group of 10 normal individuals. The group of 18 patients with gonarthrosis was studied by ultrasound (US) before knee prosthesis surgery. The cartilage thickness was measured within the weight-bearing area. US re-evaluation and histological measurements were made on the pathological specimen following the operation. Results of pre- and post-operative US data were compared with histological data. A good correlation between these measurements was found [P(t)〉10%]. In order to have comparative reference values of the articular cartilage within the weight-bearing area of the femoral trochlea a group of 10 control subjects was also studied with US as above. We found that the articular cartilage thickness of the femoral trochlea in the weight-bearing area has a mean of 2.2±0.3 mm for the lateral condyle and 2.3±0.2 mm for the medial condyle. The intra-observer and inter-observer difference in measurements was evaluated with Student's t-test. Our data demonstrate that US measurements of articular cartilage thickness of femoral condyles is a sensitive and reproducible technique which permits early diagnosis and management of knee arthropathy as well as quantification of cartilage damage.
