    The study analyzed 153 patients with Inflammatory Bowel Disease Unclassified (IBD-U) over a long-term follow-up period.

  • 2

    Patients with IBD-U had a mean age of 46.6 years and a mean disease duration of 13.1 years.

  • 3

    IBD-U patients were less likely to receive mesalazine compared to ulcerative colitis but more likely than Crohn's disease patients.

  • 4

    Biologics were used more frequently in IBD-U patients than in ulcerative colitis patients but less than in Crohn's disease patients.

  • 5

    At the end of follow-up, 88.2% of patients remained classified as IBD-U, indicating stability in diagnosis over time.
