Methods: In a retrospective study, 62 patients underwent CE in our department, each case was scored by six factors: adequate
bowel cleansing, duplicates, impurities, clearance, air bubbles and brightness. The final score was compared to the diagnosis accuracy. Results: According to the reviewing, there were significant difference of the comparison of 2 groups’ scores (Qualified, unqualified) (P < 0.001). Receiver operating Cytoskeletal Signaling inhibitor characteristic curve analysis indicted that the score less than or equal to 71 was the best critical point for predicting an poor quality including medium and unqualified (the senstivity and specificity were 87.5%, 83.2% respectively). Conclusion: The CE images score system was reliable and effective
in reviewing and evaluating CE cases quality, it should be further studied. Key Word(s): 1. Capsule Endoscope; 2. Image Quality; 3. Profile Score; Presenting Author: RONG CCI-779 concentration WU Additional Authors: GUOXIONG LI Corresponding Author: GUOXIONG LI Affiliations: Gastrointestinal Department Objective: Compare with the conventional endoscopy, white vinegar staining, narrow band imaging (NBI) guidance in Barrett esophageal biopsy significance. Methods: 126 endoscopic BE patients diangnosed from February in 2012 to February in 2013 were enrolled. They were randomly divided into three groups: the control group of 42 cases, male 30 cases, female 12 cases, age 26–76 years old, average 51.02 ± 12.15 years old; white vinegar group 42 cases, male 28 cases, female 14 cases, age 23–74 years old, average 上海皓元医药股份有限公司 50.29 ± 12.81 years; 42 cases in group NBI, male 31 cases, female 11 cases, age 28–81 years old, average 52.64 ± 11.85 years old. On three groups of intestinal metaplasia and dysplasia detection rate for comparison. Results: Intestinal epithelial metaplasia of white vinegar group was markedly higher than that of
the control group, the difference was statistically significant (X2 = 4.429, P = 0.035); NBI group and white vinegar group dysplasia detection rate is higher than that of control group, but no significant difference; with intestinal metaplasia or (and) with dysplasia of esophageal mucosa were higher “white effect” than that of Barrett Inflammatory changes, the difference was statistically significant (X2 = 5.459, P = 0.019). Conclusion: the white vinegar staining can improve the detection rate of intestinal metaplasia, narrowband endoscopic and white vinegar staining can improve the detection rate of special-shaped lesions, the detection rate of whitening effect is high in intestinal metaplasia and dysplasia.
