Localization of small islet-cell tumors. Preoperative and intraoperative ultrasound, computed tomography, arteriography, digital subtraction angiogra…

1985

A total of 42 islet-cell tumors were examined between 1972 and 1984. Problems of localization were only encountered in 31 tumors less than 2 cm in diameter. Of 31 small tumors, 27 were correctly localized using a combined diagnostic approach: ultrasound was successful in 12/20 tumors, CT in 9/21, angiography in 20/31, intraarterial digital subtraction angiography in 1/2, and pancreatic venous sampling in 13/16. The smallest tumor found by ultrasound and CT was 7 mm in diameter. Intraoperative ultrasound demonstrated all 9 insulinomas examined. Currently, the most useful techniques for localizing small islet-cell tumors are ultrasound, CT, and angiography. CT is particularly useful for tumor…

Anwendungsm�glichkeiten der intraoperativen Sonographie

1983

Sonographie, Computertomographie, Angiographie und endoskopisch retrograde Cholangiopancreaticographie haben sich in der Allgemein- und Gefaschirurgie als wertvolle Untersuchungsmethoden etabliert. Schwierigkeiten bestehen jedoch manchmal in der Korrelation der Praoperativen Befunde mit dem intraoperativen Befund. Hier ist das Anwendungsgebiet der intraoperativen Sonographie (IOS) zu sehen. Sie bietet dem Chirurgen eine zusatzliche Information durch Darstellung von pathologischen Gefasprozessen, Kontrolle von Gefasanastomosen, intraoperative FlowMessung in Gefasen, Lokalisationsdiagnostik in parenchymatosen Organen. Die intraoperative Sonographie ist somit ein neues Instrument des Chirurgen…
