“…NBI utilizes red-green-and-blue filters to modify WL endoscopy (WLE): the blue light filter (400–430 nm) highlights the capillaries in the superficial mucosa through mean peak absorption of hemoglobin (415 nm), while the green light filter (525–555 nm) penetrates deeper into the mucosa [1]. This results in greater clarity of mucosal surface structures due to the increased contrast between mucosa and superficial vessels, which appear brown/black [3]. …”

“…The first commercially available NBI systems (Lucera Spectrum and Exera II [1, 3]) produced images that were darker than WL (dark NBI), while the second-generation NBI systems released in 2012 (Lucera Elite and Exera III) exhibit an improvement in the light source that allows brighter images (light NBI) [3, 5]. High magnification is defined by the capacity to perform a zoom in an image.…”

“…This technique can be simply activated and deactivated during endoscopy, making it easier to switch between the standard mode and the NBI mode [3]. It reveals both vascular and mucosal patterns without dye application, is easy to perform and user-friendly, is widely available, and allows for inspection of the whole endoscopic field.…”

“…No reported complications have been attributed to the use of NBI. Disadvantages over WLE alone include a prolonged duration of examination and the need for training to correctly interpret findings and decrease interobserver variability [3, 8]. …”

Narrow-band imaging is an advanced imaging system that applies optic digital methods to enhance endoscopic images and improves visualization of the mucosal surface architecture and microvascular pattern. Narrow-band imaging use has been suggested to be an important adjunctive tool to white-light endoscopy to improve the detection of lesions in the digestive tract. Importantly, it also allows the distinction between benign and malignant lesions, targeting biopsies, prediction of the risk of invasive cancer, delimitation of resection margins, and identification of residual neoplasia in a scar. Thus, in expert hands it is a useful tool that enables the physician to decide on the best treatment (endoscopic or surgical) and management. Current evidence suggests that it should be used routinely for patients at increased risk for digestive neoplastic lesions and could become the standard of care in the near future, at least in referral centers. However, adequate training programs to promote the implementation of narrow-band imaging in daily clinical practice are needed. In this review, we summarize the current scientific evidence on the clinical usefulness of narrow-band imaging in the diagnosis and characterization of digestive tract lesions/cancers and describe the available classification systems.

“…White light is filtered in order to allow only the limited wavelengths of 415 nm and 540 nm to reach the mucosa. This technique exploits the principle that the depth of light penetration is proportional to wavelength [8][9][10]. By restricting the spectrum to visible blue and green light, penetration is limited to the superficial mucosal layers.…”

Advances in optical gastrointestinal endoscopy: a technical review

View full text Add to dashboard Cite

Optical endoscopy is the primary diagnostic and therapeutic tool for management of gastrointestinal (GI) malignancies. Most GI neoplasms arise from precancerous lesions; thus, technical innovations to improve detection and diagnosis of precancerous lesions and early cancers play a pivotal role in improving outcomes. Over the last few decades, the field of GI endoscopy has witnessed enormous and focused efforts to develop and translate accurate, user‐friendly, and minimally invasive optical imaging modalities. From a technical point of view, a wide range of novel optical techniques is now available to probe different aspects of light–tissue interaction at macroscopic and microscopic scales, complementing white light endoscopy. Most of these new modalities have been successfully validated and translated to routine clinical practice. Herein, we provide a technical review of the current status of existing and promising new optical endoscopic imaging technologies for GI cancer screening and surveillance. We summarize the underlying principles of light–tissue interaction, the imaging performance at different scales, and highlight what is known about clinical applicability and effectiveness. Furthermore, we discuss recent discovery and translation of novel molecular probes that have shown promise to augment endoscopists' ability to diagnose GI lesions with high specificity. We also review and discuss the role and potential clinical integration of artificial intelligence‐based algorithms to provide decision support in real time. Finally, we provide perspectives on future technology development and its potential to transform endoscopic GI cancer detection and diagnosis.
