To improve the diagnostic accuracy of intraoperative ultrasonography (IOUS) in biliary neoplasms, particularly gall bladder, we investigated the usefulness of the Sonazoid contrast agent in a preliminary study.\nSubjects and Methods:We examined IOUS images of 23 patients with gall bladder disease. Sonazoid was administered intravenously, and early arterial and venous phase images of the tumor were obtained during laparotomy.\nResults:Tumors included the localized type of adenomyomatosis in the fundus of the gallbladder (GAM) in seven patients as benign controls, adenomatous diseases in three, and gallbladder carcinoma (GC) in 13. Sonazoid IOUS scanning was performed in all patients, with no adverse effects. Although GC showed high enhancement in 77% of the tumors, GAM and adenoma also showed mild enhancement in more than half of them. Pseudo-positivity was observed in one case of hyperplastic polyps, and pseudo-negativity was observed in two patients. Cholesterol polyps and a suspicious lesion of liver metastasis by the computed tomography were not enhanced with Sonazoid treatment.\nConclusion:Although there remains a problem of pseud-positivity in the intracystic lesions, Sonazoid IOUS may be a useful tool to detect vascularity and its location or extension of gallbladder diseases; however, neither significance of differential diagnosis with benign diseases nor other clinical significance was found.
