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. Methods From 2003 to 2015 we included adult patients who consecutively underwent oesophago‐gastro‐duodenoscopy (OGD) with duodenal biopsies assessing the overall and annual occurrence of DIL and CD and the prevalence of Hp gastritis. Results 160 (2.3%) patients with DIL and 275 (3.9%) with CD were detected among 7001 patients. CD occurrence was higher from 2003 to 2011, while since 2012 DIL occurrence gradually increased significantly compared to CD ( p = 0.03). DIL patients were more frequently female ( p = 0.0006) and underwent OGD more frequently for dyspepsia ( p = 0.002) and for indications not related to gastrointestinal symptoms than CD patients ( p = 0.0003). Hp gastritis occurred similarly in CD and DIL patients but the latter had higher frequency of atrophic body gastritis ( p = 0.005). Conclusions DIL is a condition increasing in the general endoscopic population mainly diagnosed by chance. Concomitant gastric histological evaluation is able in one third of DIL patients to identify associated possible causes of DIL, such as Hp and atrophic gastritis.
