A simple way of avoiding post-ERCP pancreatitis.

Background: Pancreatitis occurs in up to 30% of patients who undergo ERCP. This study tested the hypothesis that post-ERCP pancreatitis can be avoided by initially accessing the bile duct with a soft-tipped Teflon tracer 0.035-inch guidewire.

In diffuse atrophic gastritis, routine histology underestimates Helicobacter pylori infection.

Background: histologic detection of shows high diagnostic accuracy in chronic nonatrophic gastritis. However, when atrophy occurs, the sensitivity of bacterial detection varies. This study assessed the routine histologic sensitivity for current infection in patients with atrophic gastritis, with and without intestinal metaplasia.
