## TL;DR

This study finds that older age at diagnosis and surgery is linked to higher dysplasia risk in ulcerative colitis patients undergoing colectomy.

## Contribution

The study identifies age as a novel risk factor for dysplasia in UC patients from an Iranian national registry.

## Key findings

- Patients with dysplasia were older at diagnosis and surgery compared to those without dysplasia.
- Age emerged as a significant risk factor for dysplasia in UC patients undergoing colectomy.
- No significant associations were found between dysplasia and other clinical factors.

## Abstract

Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) marked by rectal and colon inflammation, leading to relapsing symptoms. Its prevalence is increasing, particularly in developed nations, impacting patients’ health. While its exact cause remains unclear, genetic and environmental factors are implicated, elevating the risk of colorectal cancer (CRC). Colectomy, though declining, is still performed in select UC cases, necessitating further study.

We analyzed data from the Iranian Registry of Crohn’s and Colitis (IRCC) to examine UC patients undergoing colectomy. We collected demographic and clinical data from 91 patients, focusing on dysplasia. Statistical analyses assessed dysplasia risk factors.

Patients with dysplasia were older at diagnosis and surgery compared to those without dysplasia. Age emerged as a significant risk factor for dysplasia in UC patients undergoing colectomy. No significant associations were found between dysplasia and other factors.

Age plays a crucial role in dysplasia risk among UC patients undergoing colectomy. Older age at diagnosis and surgery may indicate a higher risk of dysplasia and CRC. Clinicians should consider age when managing UC patients and implementing screening protocols. Further research with larger samples is needed to confirm these findings.
