Endoscopic ultrasonography (EUS) has been shown to be superior to conventional CT in detecting and staging pancreatic cancer. We conducted a prospective trial to compare EUS and MDCT, in discriminating benign/malignant, in determining local and vascular invasion of a suspected pancreatic cancer and deciding its resectability.
The study was performed at the Gastroenterology Department of Izmir Ataturk Training and Research Hospital, from June 2009 to June 2010, all patients with suspected pancreatic and periampullary tumors referred to our department were enrolled. A total of 56 patients were evaluated at the beginning. Five patients having distal CBD tumor (n=2), gallbladder tumor (n=1) and papillary tumor (n=2) were excluded from the study. Analysis was done for the remaining 51 patients.
For the diagnosis of resectability/unresectability, EUS alone demonstrated a definite role in 4 (9%) of the 43 patients in confirming surgical and pathologic results and MDCT alone demonstrated a definite role in 6 (14%) of the 43 patients in confirming their results. An accurate diagnostic decision regarding resectability/unresectability was accomplished in 27 (63%) patients with EUS and MDCT.
While MDCT is clinically quite effective, in terms of a correct resectability/unresectability decision, EUS should also be used.
