목적 : 소화성 궤양 환자에 있어 H. pylori 박멸은 재발 억제를 위해 시행되고 있으나 박멸 후 장기간 추적에 대한 국내 보고는 드문 실정이다. 본 연구에서는 소화성 궤양으로 H. pylori 박멸요법을 시행받고 박멸이 확인되었던 환자에서 H. pylori 재감염율, 궤양의 재발을 장기간 고찰하고자 하였다. 방법 : 상부소화관 내시경검사상 H. pylori 양성인 소화성 궤양 환자 중 H. pylori 박멸요법을 시행하고 6주 이후에 박멸을 확인한 환자 763명 중 4년간 장기간 추적이 가능했던 환자 32명을 대상으로 상부소화관 내시경검사 소견, 13C-요소호기검사를 통한 H. pylori 감염 여부를 확인하여 기록하였다. 결과 : 32명 중 남성은 22명, 여성은 10명이었고, 평균 연령은 51.7세 (29∼69세)였으며 내시경적 진단은 위 궤양 9명, 십이지장 궤양 12명, 위 궤양 및 십이지장 궤양 11명이었다. 4년간의 추적 기간 동안 H. pylori 재감염은 2명에서 있었고, 연간 재감염율은 1.6%였다. 32명의 환자 중 3명에서 궤양의 재발이 있어 9.4%의 재발율을 보였다.

Background : Eradication therapy for H. pylori infection is known to decrease the recurrence rate of peptic ulcer disease. The aim of this study was to evaluate longterm effect of H. pylori eradication on the recurrence of peptic ulcer disease and the reinfection rate after treatment in Korea. Methods : Between July 1996 and February 1997, 763 patients who were diagnosed peptic ulcer diseases and H. pylori infection after upper endoscopies in Soonchunhyang university hospital. Among those patients, we reviewed 32 patients who achieved eradication of H. pylori after eradication therapy and could be followed for up to 4 years by 13C-urea breath test or endoscopy. Results : The mean age of the patients was 51.7 years (range: 29～68). Nine patients had gastric ulcer, 12 had duodenal ulcer and 11 had duodenal and gastric ulcer. An annual reinfection rate of H. pylori was 1.6% in our study. After H. pylori eradication, recurrence of peptic ulcer was detected in three patients (9.4%). Conclusion : In our study, the reinfection rate was similar to rates observed in developed countries. H. pylori eradication was effective for preventing recurrent peptic ulcers.(Korean J Med 63:23-28, 2002)
