    Notizen: Abstract The interplay between esophageal motility and gastroesophageal reflux (GER) was investigated with a new ambulatory system of 24-h monitoring of intraesophageal pressures and pH (MP24). The technique allows for simultaneous digital recordings and off-line data analysis. Both computer-aided and visual analyses were used, and algorithms for intercorrelation of mano- and pH-metry were developed. In a group of normal volunteers the physiological response of esophageal motility on GER was defined. In unselected patients suffering from GER disease, the esophageal motility prior to and during GER events was analyzed. In healthy people, most GER episodes occurred spontaneously and were cleared from the distal esophagus by peristaltic contractions. In GER patients, reflux episodes were often preceded by irregular contractions; during GER, esophageal motility was less often peristaltic compared with controls. Therefore, we conclude that MP24 gives relevant information in GER disease which might help in selecting patients for medical or surgical therapy.

    Notizen: 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.

    Beschreibung / Inhaltsverzeichnis: 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.
    Notizen: 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.
