Gastroenterology and Hepatology is the first journal to cover the latest advances in pathology of the gastrointestinal tract, liver, pancreas, and bile ducts, making it an indispensable tool for gastroenterologists, hepatologists, internists and general practitioners. In addition to the rigorously selected, systematically peer-reviewed manuscripts published in the research sections (Original Articles, Scientific Letters, Editorials, and Letters to the Editor), the journal also contains other important sections, such as Review Articles and Clinical Decision-Making Support, which offer in-depth reviews and updates on issues relating to the specialty.

Abstract

Objective

There is little information available at the national level on inflammatory bowel disease (IBD) in Argentina. The objective was to describe the methodology of the Argentinian Crohn's Disease and Ulcerative Colitis Registry (RADECCU).

Patient and methods

RADECCU was developed in 2023 with the aim of facilitating the collection of relevant information from patients with IBD in Argentina. After the registry's website platform was developed (01/2023), a nationwide promotion campaign was carried out to incorporate centers into RADECCU.

Results

From 02/2023 to 6/2025, 69 centers (41 private, 28 public) were incorporated, including 142 professionals, and 4081 patients (2275 women and 1806 men) were enrolled in the registry.

Conclusion

RADECCU is the first national IBD registry in Argentina. This registry will provide information on the status of IBD in Argentina and contribute to Latin American data with the potential to generate real-world evidence on different aspects of interest.
