Evaluation of the effect of H. pylori eradication on regression of H. pylori-related gastric polyp (Ranomized controlled trial)
Study design: open labeled RCT
Study group H. pylori eradication group (N=17), non-eradication group (N=15)
Treatment plan
Baseline EGD
: 0.3-1cm sized polyp - bx & CLO test (antrum & body)
==> if H. pylori positive and eligible patients, randomization
Triple therapy
UBT (4week after eradication)
Follow-up EGD: gross finding, CLO test
Evaluation of polyp regression
Full description
(A) Study population
inclusion HP-realetd polyp polyp size with 0.3cm-1cm 20 yr - 70yr exclusion peptic ulcer, healing stage or acute stage recent use of PPI within 4weeks Liver cirrhosis, renal insufficiency, other serious chronic or acute disease current infection of other bacteria, virus, or fungus cancer, psychologic disease heavy drinker drug abuser pregnant women, Penicillin allergy, digoxin, antifungal, wafarin previosu H. pylori eradication enroll gastric polyp with bleeding or malignant transformation tiny polyp less than 3mm.
(B) Study method
Study design: open labeled RCT Study group H. pylori eradication group (N=17), non-eradication group (N=15)
Treatment plan
Baseline EGD: 0.3-1cm sized polyp - bx & CLO test (antrum & body) ==> if H. pylori positive and eligible patients, randomization Triple therapy UBT (4week after eradication) if eradication failure in triple therapy, 2nd line treatment (metroniazole based quadraple therpay) and the UBT (4week after eradication) Follow-up EGD (3-9M): gross finding, CLO test
Evaluation of polyp regression
disappear regression over 50% (size, number) no change or increase (size, number)
Statistical analysis
Chi-square test to compare polyp regression between treatment & control group. t-test to compare continuous variables between treatment & control group. Paired T-test to compare the size between baseline and follow-up EGD. Regression analysis: univariate & multivariate analysis.
