| 1 | Antralization at the edge of proximal gastric ulcers:Does Helicobacter pylori infection play a role?显示文摘AIM: To determine the prevalence of antralization at the edge of proximal gastric ulcers, and the effect ofH. pylori eradication on the mucosal appearances.
METHODS: Biopsies were taken from the antrum, body and the ulcer edge of patients with benign proximal gastric ulcers before and one year after treatment. Gastric mucosa was classified as antral, transitional or body type.H. pylori positive patients receivedeither triple therapy, or omeprazole.
RESULTS: Patients with index ulcers in the incisura, body or fundus (n=116) were analyzed. Antral-type mucosa was more prevalent at the ulcer edge inH. pylori-positive patients thanH.pylori-negative patients (93% vs 60%, OR=8.95,95%CI: 2.47-32.4, P=0.001). At one year, there was a significant reduction in the prevalence of antralization (from 93 % to 61%, P=0.004) at the ulcer edge in patients with H. pyloribeing eradicated. However, there was no difference in the prevalence of antralization at the ulcer edge in those with persistent infection.
CONCLUSION: H. pylori infection is associated with antralization at the edge of proximal gastric ulcers, which may be reversible in some patients after eradication of the infection. | Harry Hua-Xinag Xia Shiu Kum Lam Wai Man Wong Wayne Hsing Cheng Hu Kam Chuen Lai Sau Hing Wong Suet Yi Leung Siu Tsan Yuen Nicholas A.Wright Benjamin Chun-Yu Wong | 2003 | World Journal of Gastroenterology2003，9，6： | 2 |
