Abstract | BACKGROUND: AIMS: METHODS: Standard endoscopy and endomicroscopy were performed in 18 pouches. Confocal images were scored for the presence of villous atrophy, inflammation, ulceration, colonic metaplasia and dysplasia. Targeted biopsies were taken. Endomicroscopic and histological findings were compared. RESULTS: At standard endoscopy, the signs of pouchitis were recorded in 7/18 (38.9%) patients. At endomicroscopy, pathological features were found in 16/18 (88.9%), villous atrophy in 15/18 (83.3%), inflammation in 13/18 (72.2%), ulceration in 3/18 (16.7%), and colonic metaplasia in 12/18 (67.7%). No dysplasia was observed. At histology, abnormalities were present in 17/18 (94.4%): villous atrophy in 15/18 (83.3%), inflammation in 17/18 (94.4%), ulceration in 6/18 (33.3%), colonic metaplasia in 15/18 (83.3%). Morphological changes of the ileal pouch could be predicted with an accuracy of 94.4% (95% CI: 74.2-99.0). The k-value for intra- and interobserver agreement was 0.93 and 0.78, respectively. CONCLUSIONS: Endomicroscopy may be helpful in the evaluation of morphologic changes in ileal pouch. The small size of the population sample requires further studies for the results to be confirmed.
