[Narrow band imaging for detection of non-polypoid colorectal neoplasms].
Non-polypoid (flat and depressed) colorectal neoplasms (NP-CRNs) are more difficult to detect by conventional white light colonoscopy (WLC) or computed tomography colonography, because the subtle findings can be difficult to distinguish from those of normal mucosa. Narrow band imaging (NBI) has been reported to highlight the mucosal capillaries of neoplastic lesions, and thus increase the detec...
متن کاملA multicenter validation of an endoscopic classification with narrow band imaging for gastric precancerous and cancerous lesions.
BACKGROUND AND STUDY AIM The reliability and external validity of narrow band imaging (NBI) in the stomach have not been described consistently. The aim of the current study was to describe and estimate the accuracy and reliability of a simplified classification system for NBI in the diagnosis of gastric lesions. METHODS Consecutive patients undergoing NBI endoscopy at two reference centers (...
متن کاملUsefulness of magnifying narrow-band imaging endoscopy for the diagnosis of gastric and colorectal lesions.
A series of studies about the potential usefulness of magnifying endoscopy with narrow-band imaging (NBI) for the diagnosis of gastric and colonic lesion is reviewed. Concerning the magnifying NBI appearances of gastric lesions, a light blue crest is a highly accurate sign of the presence of histological intestinal metaplasia. Also, the degree of irregularity of the mucosal and vascular pattern...
متن کاملNarrow band imaging for bladder cancer
Narrow band imaging (NBI) is a newly developed technology aiming to provide additional endoscopic information for patients with bladder cancer. This review focuses on the diagnostic accuracy and treatment outcome using NBI cystoscopy for the treatment of non-muscle invasive bladder cancer. Current results showed improved sensitivity of NBI cystoscopy compared to conventional white light cystosc...
متن کاملVisual assessment of colorectal flat and depressed lesions by using narrow band imaging
Background and study aims Visual assessment of laterally spreading tumors non-granular type (LST-NG) and depressed lesions by narrow band imaging (NBI) without magnification has not been studied. We investigated the role of non-magnifying NBI in detecting LST-NG and type IIc lesions on colonoscopy. Patients and methods This retrospective study examined consecutive patients diagnosed as havi...
