![]() The benefits of NBI towards better patient outcomes is clear: Detecting malignant lesions earlier enables treatment options with better efficacy and improved patient prognosis. NBI Benefits Patients and HCOs: Improving Outcomes while Reducing Costs With more early-stage detection coupled with more precise surgical excision of malignant lesions, it has been shown to significantly reduce recurrence rates. NBI allows ENT specialists to diagnose and treat early laryngeal cancer even more precisely and reliably In such settings, NBI’s advanced visualization allows for smaller margins, leaving less unwanted damage to healthy mucosa tissues, which is especially important when operating upon delicate structures like the vocal folds. ![]() NBI is suitable for numerous endoscopic procedures in ENT including as laryngoscopy, oral cavity examination, sinus surgery as well as for procedures in otology leading to the improved detection of carcinoma in situ and other diseases. In ENT medicine, NBI can be used throughout a patient’s journey from diagnosis to follow-up procedures, and can be used in the operating room as well as during outpatient visits. With NBI, lesion limits can be visualized better, enabling the clinician to precisely mark and perform resection with visualization levels not previously possible. In urology, NBI is proving useful beyond diagnosis: In the treatment of NMIBC, transurethral resection of bladder tumor is often required. For example, whether used in initial screening or follow up procedures such as cystoscopy, the implementation of NBI is detecting NMIBC earlier and having a significant impact upon the reduction of recurrence NBI is reshaping urology diagnostics, where increased visualization of superficial structures is providing urologists with the best chance of obtaining optical diagnosis for non-muscle invasive bladder cancer (NMIBC) 7 NBI not only improves polyp detection rate, but the image quality also allows for highly accurate optical predictions of polyp histology – reducing the need for costly pathological analysis With colorectal cancers, the detection and removal of polyps remains the most effective form of prevention, and using WLI these can often be missed NBI is also aiding the assessment of colorectal lesions. Another esophageal disease, squamous cell carcinoma, is too being detected with greater reliability with the use on NBI With NBI, clinicians are able to identify neoplastic changes earlier to enable more treatment options and improved patient outcomes. When diagnosed at a late stage, prognosis is poor for patients with Barrett’s esophagus. , a condition that carries a high risk of developing into esophageal adenocarcinoma. NBI technology has been adapted for gastroenterology, where NBI has proven to be a reliable tool for targeted biopsy in Barrett’s esophagus ![]() Here we will look at the three clinical fields where NBI is making the greatest impact. NBI is rapidly being adopted as a diagnostic tool, and this is supported by regulators including European Society for Gastrointestinal Endoscopy (ESGE), European Association of Urology (EAU) and European Laryngological Society (ELS) among others, who have integrated NBI into their diagnostic guidelines. It’s also very easy to switch between WLI and NBI as a filter located at the front of the endoscope lamp can be activated at the push of a button. Not only does earlier detection leave greater scope and more options for treatment, it can also reduce recurrence of abnormal lesions such as dysplasia and cancer if an earlier diagnosis is made. NBI overcomes this issue as the high-contrast visualization helps clinicians to identify mucosal lesions more easily and earlier on in their development. ![]() Therefore, detecting premalignant changes and/or malignant structures is challenging and such lesions can be missed with WLI alone. This is the primary feature that clinicians look for when performing an endoscopy, and with WLI it can be challenging to visualize these microvascular patterns. But how is improved visualization of blood vessels beneficial to endoscopy? In short, it makes for a far-improved diagnostic tool: Malignant mucosal lesions exhibit increased angiogenesis and therefore often present with a significantly increased number of blood vessels
