Description
The endoscopic appearance of gastric antral vascular ectasia (GAVE) can be easily misinterpreted as inflammatory changes of gastric mucosa. We report on a case of GAVE that had been missed by conventional transnasal endoscopy but was diagnosed by flexible spectral imaging color enhancement (FICE) with a transnasal endoscope. A 45-year-old woman with severe anemia presented with a 1-month history of increasing fatigue. She was previously diagnosed as having acute antral gastritis by conventional transnasal endoscopy (EG 530N2) because of the presence of reddish mucosal changes on the entire antral rugal fold. However, the FICE images produced using a combination of new processor system (VP4450) and new small-caliber endoscope (EG 530NW), did not show reddish mucosal changes on the entire rugal fold, but gave a clear image of dilated vessels associated with GAVE distinct from the surrounding normal mucosa on the same fold. These findings are useful to differentiate GAVE from ordinary gastritis. The lesions of GAVE were managed with a combination of focal pulse and spray-painting techniques to obliterate the bulk of the disease in two sessions of argon plasma coagulation therapy. Three months later, the patient recovered from iron deficiency anemia with an oral medication of iron tablets.
