Evaluation of Inflammation Activity in Ulcerative Colitis by pCLE
Evaluation of Inflammation Activity in Ulcerative Colitis by Probe-based Confocal Laser Endomicroscopy
Study Overview

Conditions
Detailed Description
Patients with acute inflammatory infiltrates seen on histological assessment are more likely to experience relapse than are those without infiltrates,studies suggest that severity of inflammation is a risk factor for colorectal neoplasia in UC.
The assessment of inflammation activity by conventional colonoscopy is inaccurate in the prediction of acute inflammation in some cases. Confocal laser endomicroscopy (CLE) allows for real-time endoscopy and histological diagnosis of gastrointestinal diseases. In our previous study, we confirmed a simplified four-grade classification system of crypt architecture(Grade A :normal; Grade B: an irregular arrangement of colonic crypts with normal size and shape, and enlarged spaces between crypts; Type C: an enlarged crypt opening and a more irregular crypt arrangement than type B; Type D: crypt destruction and / or crypt abscess) by eCLE in predicting acute inflammation, and found a good correlation with histology. In this study, the investigators aimed to test the accuracy of the proposed tne four-grade classification system in evaluating inflammation activity in UC by pCLE.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
A valuable realtime- and offline- diagnosis of pCLE in evaluating the inflammation activity in UC.
Time Frame: 2 years
|
Recruited more than 100 UC patients,pCLE diagnostic criteria was the four-grades crypt architecture classification system ( inactive cases with Grade A or B, active with Grade C or D), histological assessment according to the Geboes Index ( inactive disease with Geboes index ≤ 3.0; active disease with a index > 3.0). Using Spearman's text, calculating the corelation between pCLE real-time finding and the Geboes index, if p<0.05, it means a strong corelation,vice versa. Also for the offline diagnosis. Also calculate the corelation between white-light colonoscopy (Baron Score) and histopathology. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Good or Excellent interobserver and intraobserver agreement of pCLE diagnosis.
Time Frame: 2 years
|
Assessment of interobserver variability of pCLE was conducted in a randomized pCLE videos' order by two independent investigators.
After a 2-week interval, all pCLE videos were reassessed by the two investigators to evaluate the intraobserver agreement.
