ABSTRACT
Objective To evaluate the efficacy of narrow-band imaging (NBI) in diagnosis of color-ectal neoplasm. Methods A total of 96 colorectal neoplasm from 78 patients were observed under NBI, and the findings were compared with those from magnifying chromo-endoscopy and pathologic examinations. Re-suits The sensitivity of conventional colonoscopy in diagnosis of polyps was 78. 7%, which was increased to 99% (P < 0. 05) under NBI, with the clear identification of the shape and boundary of the lesions. Magnif-ying NBI colonoscopy provided images of pit patterns similar to those from chromo-endoscopy in diagnosis of type Ⅱ , ⅢL, Ⅳ and ⅤN, which showed better recognition than conventional colonoscopy, but less sensitiv-ity than chromo-endoscopy. Superficial vascular morphologic features could be better classified with NBI, with sensitivity of 100% and specificity at 87. 8%, which was superior to conventional colonoscopy but infe-rior to chromo-endoscopy. Conclusion Both chromo-endoscopy and NBI colonoscopy have better sensitivity and specificity in detection of colon polyps, while chromo-endoscopy reveals clear superficial structure of le-sion and pit pattern, and NBI demenstrates capillary morphology, which can distinguish neoplasm from non-neoplasm colorectal lesions. NBI, easy and convenient to switch, is an effective technique to make early di-agnosis of colorectal neoplasm.
