    Notes: Summary The efficacy of intraoperative ultrasonographic detection of colorectal cancer liver metastases was evaluated in 85 patients undergoing operation for primary colorectal tumors or liver secondaries. The results of intraoperative ultrasonography were compared with those of preoperative ultrasonography and computed tomography, as well as the intraoperative appearances of the liver. Additional information about the number of metastases was obtained in 12 cases (14.1%); 17 (24.3%) out of 70 metastases could only be detected by intraoperative ultrasonography. In 4 cases (4.7%) these lesions were solitary. As a result, the operative procedure of choice was changed in 15.3% of the patients. We conclude that intraoperative ultrasonography has a significantly higher ability to detect colorectal cancer liver metastases than preoperative methods or intraoperative inspection and palpation. Intraoperative ultrasonography should be performed in patients without preoperative evidence of liver metastases and in all patients with planned resection of metastases.

    Description / Table of Contents: Zusammenfassung 12 beatmete Intensivpatienten mit Peritonitis bzw. Sepsis wurden in einer prospektiv randomisierten Doppelblindstudie mit 300 mg Ranitidin/d bzw. 2 g Cimetidin/d jeweils über Dauerinfusion behandelt. Beide Untersuchungsgruppen waren hinsichtlich Alter, Geschlecht und Gefährdungsgrad streßinduzierter Blutungen vergleichbar. Durch Ranitidin gelang eine zur Blutungsprophylaxe ausreichende, wenn auch nicht vollständige Kontrolle des intragastralen pH-Wertes. Mit Cimetidin als Monotherapie konnten wir dagegen selbst in einer hohen Dosierung (2 g/d) bei unserem Patientengut keine ausreichende Kontrolle des Magen-pH-Wertes erzielen. Für 3 Patienten erwies sich sogar die Kombination von Cimetidin mit 2 × 10 mg Pirenzepin/d als nicht ausreichend.
    Notes: Summary Twelve patients in an intensive care unit on a respirator who had peritonitis or sepsis were treated with 300 mg/day of ranitidine or 2 g cimetidine/day, which was administered via perfusor infusion under the conditions of a random double-blind study. Both groups under study were comparable with respect to age, sex, and grade risk of stress-induced bleeding. With ranitidine, we were able to control bleeding sufficiently, but not completely control intragastric pH values. With cimetidine as monotherapy, however, even under the high dosage of 2 g/day, we were not successful in controlling intragastric pH. With three patients even the combination of ranitidine and 2 × 10 mg pirenzepine/day did not prove sufficient.

    Description / Table of Contents: Zusammenfassung In einer prospektiven Studie wurde bei 85 Patienten mit Operation colorectaler Carcinome eine intraoperative Sonographie der Leber zum Nachweis von Lebermetastasen durchgeführt. Die Befunde wurden verglichen mit den Ergebnissen der präoperativ vorgenommenen Sonographie und Computertomographie sowie der intraoperativen Inspektion und Palpation der Leber. Siebzehn (24,3%) der insgesamt 70 Metastasen dieser Untersuchungsserie konnten allein durch die intraoperative Sonographie nachgewiesen werden. Dieses betraf 12 (14,1%) der untersuchten Patienten. Vier (5,7%) dieser Herde waren solitär und betrafen 4,7% der Fälle. In 15,3% der Patienten wurde aufgrund der intraoperativen Ultraschallbefunde die Operationstaktik geändert. Beim Nachweis von Lebermetastasen colorectaler Carcinome hat die intraoperative Sonographie eine signifikant höhere Sensitivität als die präoperative Sonographie und Computertomographie bzw. die intraoperative Inspektion und Palpation. Die intraoperative Ultraschalluntersuchung sollte bei allen Patienten ohne präoperativen Nachweis von Lebermetastasen und bei Patienten mit geplanter Metastasenresektion durchgeführt werden.
    Notes: Summary In a prospective study of 85 patients with operation of colorectal cancer intraoperative ultrasonography of the liver was performed for the detection of liver metastases. The findings were compared with the results of preoperative ultrasonography and CT-scan as well as the findings of intraoperative inspection and palpation of the liver. Seventeen (24.3%) of a total of 70 metastases of this series could only be detected by intraoperative ultrasonography. This was related to 12 (14.1 %) of the examined patients. Four (5.7%) of these lesions were solitary and concerned 4.7% of the cases. Due to the intraoperative sonographic findings the tactics of operation was changed in 15.3% of the patients. Intraoperative ultrasonography has a significantly higher sensitivity for the detection of liver metastases from colorectal cancer than preoperative ultrasonography and computed tomography or intraoperative inspection and palpation. Intraoperative ultrasonography of the liver should be applied in all patients without preoperative evidence of liver metastases and in patients with a planned resection of metastases.
