Background: Duodenal intraepithelial lymphocytosis (DIL) is a histological finding characterized by the increase of intraepithelial CD3T-lymphocytes over the normal value without villous atrophy, mostly associated to coeliac disease (CD), Helicobacter pylori (Hp) gastritis and autoimmune diseases. Objective: To assess the occurrence of DIL, CD and Hp gastritis in an endoscopic population over a 13 year period.

Background: Atrophic gastritis (AG) is at increased risk of gastric neoplasia, thus surveillance gastroscopy
has been proposed.
Aims: To assess cost of detecting gastric neoplasias by surveillance endoscopy according to identified risk
factors in Italy.
Methods: Post-hoc analysis of a cohort study including 200 AG-patients from Italy followed up for a mean
of 7.5 (4–23.4) years was done. Considered risk factors were: age >50 years, extensive atrophy, pernicious
