title: Non-endoscopic method to obtain Helicobacter pylori for culture.
abstract: A sampling method to collect samples for Helicobacter pylori culture that is easier than endoscopy would be useful. We used a capsule attached to a highly absorbent nylon string, which is swallowed to obtain gastric secretions. Antral biopsy and string specimens, sequentially obtained from 36 adults with clinically suspected ulcer or gastric disease were cultured. 9 (25%) patients were negative in both tests; 18 (50%) were positive by both methods; 6 (17%) were biopsy positive and string-test negative; and 3 (8%) were biopsy negative and string-test positive. The new test is useful, simple, and causes little discomfort.
