窄带成像技术对Barrett食管治疗后随诊的临床应用

Clinical Application of Narrow Band Imaging in Post-treatment Follow-up of Barrett's Esophagus

目的探讨窄带成像技术(NBI)在Barrett食管(BE)治疗后随诊中的效果。方法收集在我院诊断为BE患者112例,经治疗后3个月和6个月后在胃镜下观察NBI分级与病理活检阳性率进行比较。结果治疗3个月和6个月后,NBI对BE的敏感性、特异性明显高于常规内镜(P <0.05);治疗3个月和6个月后,NBI图像分型I级与BE病理结果具有统计学差异(P <0.05),Ⅱ-Ⅲ级与病理活检结果无统计学差异(P >0.05)。结论 NBI在BE治疗后随诊中,如为Ⅱ级-Ⅲ级可考虑为BE未愈,仍需继续治疗,无需再次活检;如为I级,可考虑加活检以明确治疗效果。

Objective To investigate Clinical application of narrow band imaging in post-treatment follow-up of Barrett＆#39;s esophagus. Methods 112 cases of BE patients in our hospital December were collected,After treating for3 months and6 months, NBI grading and pathological biopsy positive rate were compared. Results After treating 3 months and 6 months, NBI sensitivity and specificity of BE was significantly higher than that of＆amp;nbsp;conventional endoscopy（P〈0.05）.After treating for 3 months and 6 months, I grade of NBI image classification and BE pathological results was with statistical difference（P〈0.05）, and II grade – III grade and biopsy results was with no statistical difference（P〉0.05）.Conclusion If the NBI typing results is grade II- III, BE can be considered as no cure,and there is needed to continue treatment,but no need to repeat biopsy. If the NBI type is grade I, biopsy should be performed to clarify treatment efficacy.
