Recently, multiple new endoscopic imaging technologies such as chromoendoscopy with indigo carmine, which with increased
sensitivity are able to obtain, and confocal laser endomicroscopy (CLE), which is developed to provide a more detailed visualization of the mucosa by enhancing morphology and vascularization with high specificity. Methods: In this prospective clinical trial, 20 patients from the First Hospital of Jilin University undergoing endoscopic screening and surveillance for AG were enrolled. High-definition white light endoscopy followed by indigo carmine sprayed in the antrum was performed for searching MAPK Inhibitor Library price for highly interested spot of lesions in antrum, followed by the CLE scan performed by two endoscopists experienced more than 30 CLE examinations and biopsy for standard histological pathologic diagnosis as “gold standard”, and sent to a single GI pathologist to provide diagnosis. The endoscopists CLE diagnosis and standard Cabozantinib datasheet pathologic diagnosis were compared. Results: The comparison of CLE plus chromoendoscopy to histological pathology diagnosis is sensitivity 89.00%, and specificity 87.50% in atrophic gastritis (Kappa = 0.0495, 0.4 < k < 0.75), sensitivity 97.98%, specificity 94.59% (Kappa = 0.557, 0.4 < k < 0.75). Conclusion: CLE has significant consistency to the pathology diagnosis
in the atrophic gastritis and intestinal metaplasia. CLE with chromoendoscopy enhances the diagnostic accuracy, clinical real-time result and decision. CLE with chromoendoscopy has potential advantage for diagnosis and treatment of atrophic gastritis.

Methods: We report a case of a 67-year-old woman with intermittent watery diarrhea, occurring more than 30 times per day, nausea and vomiting for 10 months without obvious cause. Her vomiting is contents of stomach after each meal. No fever, abdominal pain, tenesmus, coughing, and significant weight loss. Lab test reveal WBC 18.5 × 109/L, neutrophil 15.6 × 109/L. No findings in the stool culture, C-reaction protein, anti-nuclear antibodies series. Positron emission tomography revealed high functional metabolism or inflammation in colon. Key Word(s): 1.
