    Notes: Abstract Transrectal ultrasound (TRUS) was performed preoperatively in 35 patients with rectal carcinoma and the results were compared to histologic findings. In the same group, postoperative studies were performed in 22 patients; in women, transvaginal ultrasound (TVUS) was added to the transrectal study. According to Duke's classification modified by Astler-Coller, in relation to the “T” parameter, TRUS correctly staged 33 of 35 neoplasms (accuracy, 94.3%); one was overstaged and one was understaged. In detection of lymph node involvement, accuracy was 74% (sensitivity 69%, specificity 73.9%). Recurrent local tumors, histologically confirmed, developed in two of 22 postoperative patients who had undergone curative anterior resection. This study demonstrates that TRUS is an accurate method in preoperative staging of rectal carcinoma. In the prospective study, the role of follow-up TRUS and TVUS in detection of local recurrences is evaluated.

    Abdominal computed tomographic findings in adults with hypovolemic shock (1997)
    Springer
    Emergency radiology 4 (1997), S. 10-15

    Notes: Abstract The clinical charts and contrast mediumenhanced computed tomographic (CT) examinations of 15 adults with a history of serious shock and resuscitation were reviewed. Several hypovolemia-related abnormalities were recognizable and were variably associated with each other. Diminished caliber of the abdominal vessels with intense vascular contrast medium enhancement and renal abnormalities were the most common findings; decreased and/or increased enhancement of the abdominal organs and other hypovolemic changes were also present. Most of the series in the radiologic literature describe findings in pediatric subjects, but the various vascular and extravascular CT findings with regard to shock in adults may be different from those reported in children. Although the diagnosis of shock is based on clinical signs, hypovolemia-related CT abnormalities must be distinguished from organic lesions. CT may also identify a previously unsuspected shock state.
