Correlation of endoscopic findings with histological alterations in pediatric ulcerative colitis.

Ulcerative colitis (UC) is a chronic and relapsing inflammatory bowel disease (IBD) characterized by abdominal pain and bloody diarrhea. Its diagnosis requires endoscopy and biopsies for histopathological analysis, revealing characteristic endoscopic findings. Currently, the correlation between these endoscopic abnormalities and the histopathological diagnosis of UC remains a controversial topic in pediatrics. This study evaluates the clinicopathological association of various endoscopic alterations in UC. We conducted an analytical study of patients under 15 years old who underwent upper and lower gastrointestinal endoscopy for suspected IBD at a pediatric hospital between 2015 and 2022.
