ABSTRACT
We evaluated the efficacy of contrast-enhanced ultrasonography (CEUS) with intra-arterial injection of CO2 microbubbles in 37 cases of gall bladder diseases. CEUS clearly visualized arterial flow and vascularity in every lesions without debris and gave us the precise information of vascular structure for the differential diagnosis of gall bladder tumors. For example, highly bifurcated tumor vessels and strong enhancement was observed in gall bladder cancer and we could detect relatively strong enhancement along the lumen with lack of enhancement of Rokitansky-Aschoff sinus in localized-type adenomyomatosis. Though CEUS is now an invasive modality, it will enable us to understand the non-invasive modality such as color doppler imaging with intra-venous administration of microbubbles in the future.

A 71-year-old male suffering from an intraductal papillary tumor of the pancreas was admitted to our hospital for further investigation. Diagnostic trials, including endoscopic retrograde pancreatography, did not produce an adequate ductography because of a large amount of mucinous fluid. Therefore, we performed endoscopic ultrasonographic-guided punctured pancreatic ductography (EPPD). This procedure was safely performed without any complications. We report this initial and successful trial of EPPD.
