Endoscopy using magnification narrow band imaging (mNBI) allows detailed assessment of mucosal surface and vascular pattern. This may help in better identification and prediction of the nature of the lesion. The role of this technology in duodenum is still evolving. Studies have shown that mNBI has high accuracy in predicting villous atrophy in the duodenum. Limited data suggests that this technique can provide additional information on duodenal polyps, nodules and ampullary tumour which can help guide their management. In this paper we describe the technique for duodenal assessment using NBI and review the existing literature evaluating its role in diagnosis of various duodenal pathologies.
Core tip: Narrow band imaging endoscopy with magnification (mNBI) enables detailed assessment of duodenal villous morphology. This advantage over white light endoscopy has potential clinical benefits. There is good evidence to show that villous morphology on mNBI correlates well with histopathology. Hence villous atrophy can be diagnosed with good accuracy during mNBI and targeted biopsy can be obtained from abnormal appearing areas. Preliminary data suggest that this technology may also aid in assessment of neoplastic lesions in duodenum.
