Abstract:
Objective To evaluate the value of endoscopy with narrow-band imaging(NBI)for tar-geting biopsy of lesions in children with allergic colitis. Methods The colorectal lesions under the model of traditional white light imaging and NBI in children with allergic colitis were observed and recorded. The re-sults of biopsy under white light imaging and NBI were compared with postoperative pathological diagnosis. Results A total of 60 patients completed the study. Under NBI,47(78. 3%)rectal lesions,52(86. 7%) sigmoid colon lesions and 19(31. 7%)descending colon lesions were found. There were 21(35. 0%),25 (41. 7%),and 8(13. 3%)lesions in the transverse colon,ascending colon and iloececus,respectively. For the lesions in transverse colon and ascending colon,the detection rate under NBI was significantly higher than that under white light endoscopy[35. 0% VS 16. 7%(10/ 60),P<0. 05;41. 7% VS 18. 3%(11/ 60),P<0. 05]. No significant difference was found between two methods for the sigmoid and rectal lesion[86. 7% VS 83. 3%(50/ 60),P>0. 05;78. 3% VS 76. 7%(46/ 60),P>0. 05].There was no significant difference in ileo-cecus and descending colon[13. 3% VS 5. 0%(3/ 60),P>0. 05;31. 7% VS 28. 3%(17/ 60),P>0. 05]. The targeted biopsy results by NBI indicated that the ratio of EOS≥6/ HP was significantly higher than the biopsy results by white light imaging. Conclusion NBI is easy to operate and can discern the microcosmic structure which cannot be observed by the traditional endoscopy. It can provide higher diagnostic accuracy of allergic colitis. After suspicious lesions were found under conventional endoscopic check,NBI could be used to guide the targeted biopsy.
