Figure 1 Diagnostic yield of capsule endoscopy (CE) and push enteroscopy (PE) for the identification of a definite source of obscure gastrointestinal bleeding. Results are expressed as percentages ± 95% confidence intervals of patients randomized to CE (n = 40) and PE (n = 38) as the first-line exploration in which a definite bleeding source was identified for all sites and for small bowel, gastric, and colonic sites (*P = .02).

Figure 3 Transmission electron microscopy of sections of gastric mucosa immunostained with V4074 anti H pylori antibodies using 10-nm gold particles. (A) Three bacteria are found in the deep stroma (bottom) in between a blood vessel and a stromal cell, 2 of which are enlarged in (a1) and (a2) to show immunogold reactivity (original magnification ×58,000). Note the unusual shape of the (a1) bacterium, which closely resembles the luminal bacterium in (a) (original magnification ×58,600), also immunoreactive for H pylori antibodies. Note also marked dilation of intercellular spaces, filled with extensively developed lateral membrane placations, in H pylori-colonized epithelium (original magnification ×5400). (B) A bacterium, enlarged in (b) (original magnification ×52,500) to show H pylori immunogold reactivity is found inside a stromal vessel. Note basal epithelium on top right (original magnification ×7500). Gastroenterology 2007 132, 831-834DOI: (10.1053/j.gastro.2007.01.066) Copyright © 2007 AGA Institute Terms and Conditions
