Intraoperative ultrasound as an aid to surgical strategy in liver tumor.
Ultrasonography of the liver was performed on 27 patients during laparotomy for liver lesions--11 primary and 13 metastatic mainly colon/rectum malignancies, and three benign conditions. Supplementary information on the liver parenchyma was provided in 11 cases (41%) in which the surgical strategy was decided simply by inspection and palpation of the liver. Ultrasound was most valuable for visualizing the vascular anatomy of the liver, giving clarification in 18 cases (66%), especially the relationship of tumor to portal and hepatic veins. This was decisive for the surgical strategy in four cases, enabling resection in two and modifying planned procedure in two. In a case of polycystic liver, ultrasonography imaged deep-lying cysts and aided the fenestration procedure. Liver resection was performed in 16 cases without operative mortality. Hepatic ultrasonography is useful for determining tumor spread, but of even greater value for the determination of strategy by clarifying tumor/vascular anatomic relationships.
