Gastric polyps: a retrospective cohort analysis of 23,668 endoscopies indicates changing epidemiological and phenotypic characteristics.

Introduction: Growing adoption of endoscopic procedures in clinical practice has gradually increase the detection rate of gastric polypoid lesions.

Aim: To identify the epidemiologic characteristics of gastric polyps as well as changes of these parameters during a 15-year period.

Material And Methods: We reviewed all the upper endoscopies archived in our database reporting a polypoid lesion from 2003 to 2018.

Metastatic renal cell carcinoma presenting as a duodenal mass.

We report a case of renal cell carcinoma metastasis to the duodenum.

An unusual case of colonic mass.

Colonic metastasis due to pancreatic adenocarcinoma is extremely rare. Although it is rare, colonic metastasis should be included in the differential diagnosis of colonic mass.

Optimal duration of concomitant nonbismuth quadruple therapy as first-line therapy for Helicobacter pylori: a prospective, open-label, comparative study.

Background: Concomitant nonbismuth quadruple therapy is recommended as first-line treatment for Helicobacter pylori infection in high clarithromycin resistance areas, but the ideal duration of the regimen remains elusive. Aim of this study was to assess the efficacy and tolerability of 10- versus 14-day concomitant therapy for H. pylori eradication in an area of high clarithromycin and low dual clarithromycin/metronidazole resistance.
