摘　　要：目的通过对比同一型号两代产品的活检钳活检取材情况，分析可旋转活检钳在胃癌前病变诊断中的意义。方法同一内镜操作医师在窄带成像（NBI）胃镜下对60例怀疑胃癌前病变处分别使用2种活检钳活检，根据病理学诊断对2组取材进行比较。结果新型可旋转活检钳在取材满意度及减少对活检组织的损伤方面均优于常规活检钳（P〈0．05），前者所得病理诊断与最终诊断一致性高于后者，但无统计学意义。结论在对胃癌前病变诊断中，可旋转活检钳性能优于常规活检钳。Objective To evaluate the sampling efficiency of rotary biopsy forceps in gastric precancerous lesions. Methods A total of 60 gastric lesions with suspected pre-cancerous characters under narrow band imaging were enrolled, and consecutive samples were taken from same lesion by one endoscopist with routine and rotary forceps, respectively. The most severe pathological diagnosis was regarded as the final diagnosis. Results There was a significant difference between rotary biopsy forceps and routine ones in regarding of sample quality and capability of minimize tissue damage （ P 〈 0.05 ）. The concordance rate with final pathological diagnosis from sample taken by rotary biopsy forceps was higher than that from routine ones, but without significance （P 〉0. 05 ）. Conclusion The rotary biopsy forceps is superior to routine ones in sampling of gastric pre-cancerous lesions.
