Previous reports and our findings suggest that resection by ultrasound is of appreciable merit in liver surgery. Blood can be saved and bile leakage diminished as the larger vessels and bile ducts can be skeletonized unharmed, whereas the dissector selectively carries away the parenchyma. Otherwise virtually inaccessible tumours can be approached. The ultrasonic dissector/aspirator does not harm the tissue in depth beyond the resection surface and thus not much devitalized tissue is left in the wound.

Berichte aus der Literatur und eigene Erfahrungen zeigen, daß die Ultraschallresektion von beträchtlichem Wert in der Leberchirurgie ist. Es kann blutsparend operiert werden, Gallelecks werden verringert, da größere Gefäße und Gallengänge sorgfältig präpariert werden, während der Ultraschalldissektor selektiv das Leberparenchym abträgt. Sonst inoperable Tumoren können somit chirurgisch angegangen werden. Der Ultraschalldissektor/-aspirator läßt das tiefe Gewebe jenseits der Resektionsebene unangetastet, wodurch nur sehr wenig devitalisiertes Gewebe zurückbleibt.


Nous voulons montrer, à travers notre expérience et à la lumière de la littérature médicale, l’intérêt majeur du bistouri à ultrason en chirurgie hépatologique. Il permet une intervention peu sanglante, minimise une fuite biliaire car les gros vaisseaux sanguins, de même que les canaux hépatiques sont particuliérement bien préparés pendant l’utilisation du bistouri à ultrason sur le parenchyme hépatique. Des tumeurs non accessibles à la chirurgie en temps ordinaire le deviennent. Grâce à cet instrument, il n’y aura aucune atteinte du tissu sousjacent et donc très peu d’atteintes nerveuses.
