Background: The information on the clinicopathologic/outcome differences between ampullary adenocarcinoma (AC) and pancreatic adenocarcinoma (PC) has been conflicting to the extent that it still is questioned whether ACs need to be recognized separately from PCs.
Methods: The characteristics of 413 ACs were compared with those of 547 PCs.
Results: The ACs had a better prognosis than the PCs (5-year survival, 57 % vs 23 %; p < 0.
Purpose: The aim of this study was to compare the accuracy of colonoscopy (CS) and CT colonography (CTC) in the measurement of colorectal polyps using pathological size as a reference.
Materials And Methods: The analysis included 61 colorectal polyps in 28 patients who underwent preoperative CTC at our institution. All polyps were endoscopically resected.
