Third-Generation Capsule Endoscopy Outperforms Second-Generation Based on the Detectability of Esophageal Varices

Figure 2

Esophageal varices classified by form, according to their appearance on esophagogastroduodenoscopy. Specifically, (a) straight, small-caliber varices (stage F1); (b) moderately enlarged, beady varices (stage F2); and (c) markedly enlarged, nodular, or tumor-shaped varices (stage F3). The same varices are shown as visualized by capsule endoscopy (d–f), specifically, (d) F1 varices, (e) F2 varices, and (f) F3 varices.
