Diagnostic value of terminal ileum biopsies in patients with abnormal terminal ileum mucosal appearance.
OBJECTIVE
To investigate the necessity of obtaining routine ileal biopsy during colonoscopy in the patients with abnormal terminal ileum mucosal appearance if the inflammatory bowel disease is not considered.


METHODS
A retrospective analysis was performed for 57 patients who were referred to a private hospital for colonoscopy between January 2008 and February 2009, in whom terminal ileum intubation was achieved and an abnormal appearance was observed.


RESULTS
There were 33 men and 24 women; the mean age was 44.12±11.42 years. In 22 patients, the abnormality was ulcers and/or erosions. In 10 patients, there were mucosal nodularity and in 24, the finding was erythema. The time to reach to ileum from cecum was 28.78±24.30 s. The mean length of the examined ileum was 12.93±6.05 cm. There was no difference between groups according to distance covered in the ileum for diagnostic yield, but going further than 2 cm was important.


CONCLUSIONS
There should be no need to obtain routine biopsy in patients with abnormal terminal ileum mucosa appearance, when inflammatory bowel disease is not considered. In these patients, histopathology also reveals non-specific ileitis. Furthermore, in these patients, the macroscopic pathological diagnosis overlaps the histopathology, and it has a low diagnostic yield and lower clinical significance.
