Aims:

Microstructure and the vascularity of the superficial gastric mucosa have been evaluated more clearly with HRME and digital chromoendoscopy methods which have been used in recent years. Structural changes in the gastric mucosa is known to be closely associated with intestinal metaplasia, atrophy, Helicobacter Pylori (H. Pylori) and chronic inflammation. The purpose of this study is to investigate the efficacy of the FICE added on HRME in evaluation of structural changes in the gastric mucosa.

Methods:

A total of 104 patients were included in the study. At examination of gastric mucosal structure in patients, first HRME then HRME + FICE methods were used. After imaging the investigated areas were examined histologically. Mucosal appearance was evaluated by the modified Yagi classification. HRME + FICE technique that was undefined earlier in the antrum, mucosal pattern observed independently of the underlying mucosal image is also classified as Type 5.

Results:

Sensitivity and specificity values of H. Pylori detection with the image patern HRME in the antrum was found as 67.9% and 84.6% while 93.5% and 92.3% with YRME+FICE, respectively. The Type 5 patern that we consider to be associated with intestinal metaplasia was not observed in any patient with HRME. Sensitivity and specificity values of Type 5 pattern observed with HRME + FICE method for intestinal metaplasia were 50% and 98.8%, respectively.

Conclusions:

The findings shows that digital chromoebdoscopic method FICE added HRME application has contributed an additional method for the presence of H. Pylori and intestinal metaplasia to HRME and has a higher sensitivity and specificity. Previously not defined in the assessment of gastric mucosa with FICE, antrum mucosal thinning is probably due to secondary submucosal vascular fields watched “patched image” (Type 5), especially for the diagnosis of intestinal metaplasia may be finding a lead.
