A, Standard videoendoscopic image of columnar mucosa in the distal esophagus without visible mucosal pit pattern before AA chromoendoscopy. B, High-resolution AA-enhanced image of the same area of esophageal columnar mucosa, showing a villous mucosal pit pattern in 1 area (yellow arrow) corresponding to intestinal metaplasia in biopsy specimens and a reticular-type pit pattern (white arrow) corresponding to gastric metaplasia. Both images obtained with a “close focus” high-resolution endoscope (XGIF-H160Y2; Olympus Corp, Center Valley, Pa), which allowed close mucosal inspection, without loss of focus and combined optical and digital magnification of ×75.
