Utility of CEH-EUS uses sonographic contrast agent to diagnose pancreatic tumors

Endoscopic ultrasonography (EUS) is a highly sensitive diagnostic method for the detection of small pancreatic carcinomas. Recently, there have been some reports describing the utility of contrast-enhanced harmonic EUS (CEH-EUS) which uses sonographic contrast agent for differentiation of a pancreatic mass.

A research team from Japan reported a case of small adenocarcinoma of the pancreas distinct from branch duct intraductal papillary mucinous neoplasm (IPMN) in which investigation by EUS took place every 6 mo and diagnosis was made accurately by additional CEH-EUS during the follow-up of the branch duct IPMN.

Their study will be published on November 21, 2009 in the World Journal of Gastroenterology.

Their results suggest that the performance of periodical EUS with CEH-EUS imaging during the follow-up of branch duct IPMN allowed the establishment of an accurate diagnosis of the disease.
