Abstract:
Objective To investigate the diagnostic value of narrow?band imaging in patients with nonampullary duodenal superficial elevated lesions. Methods Analysis were limited to respondents diagnosed with nonampullary duodenal superficial elevated lesions on endoscopic examination. The lesion distribution, fusion, diameter, vascular and surface pattern were evaluated and compared with NBI mode according to pathological group. Results 72 cases were collected, 35 (48.61%) cases were inflammation, 17 (23.61%) cases were heterotopic gastric mucosa, 12 (16.67%) cases were gastric duodenal metaplasia and 8 (11.11%) cases were adenoma. Among the four types of duodenal lesion, solitary adenomatous lesions were observed more frequently and larger in diameter. Surface pattern of inflammatory lesions were consistent with the surrounding mucosa. Vascular pattern and fusion may be helpful to differential some superficial elevated lesions. Conclusion Nonampullary duodenal superficial elevated lesions can be identified preliminarily by NBI. Meanwhile, diagnosis accuracy and positive rate can be improved by target biopsy.
