Gastroesophageal reflux disease (GERD) has a large economic burden with important complications that include esophagitis, Barrett's esophagus, and adenocarcinoma. Despite endoscopy, validated patient questionnaires, and traditional ambulatory pH monitoring, the diagnosis of GERD continues to be challenging. Areas covered: This review will explore the difficulties in diagnosing GERD with a focus on new developments, ranging from basic fundamental changes (histology and immunohistochemistry) to direct patient care (narrow-band imaging, impedance, and response to anti-reflux surgery)...

A 60-year-old woman underwent colonoscopy for a positive fecal immunochemical test. A 5 mm sessile polyp (Paris type 0-Isp) was found in the lower rectum (Figure 1a). This polyp was diagnosed as a low-grade adenoma based on findings of magnification colonoscopy with narrow band imaging (Figure 1b) and then was resected in a single piece with cold snare polypectomy.

High-quality colonoscopy is mandatory to prevent adenoma recurrence and colorectal cancer. In the past few years, technical advances have been developed with the purpose of improving adenoma detection rate (ADR), one of the most important validated colonoscopy quality benchmarks. Several techniques or devices are used to optimize visualization: observation techniques; add-on devices; auxiliary imaging devices; colonoscopes with increased field of view; and colonoscopes with an integrated inflatable reusable balloon...

Endometriosis is a common disease affecting reproductive age women. Pain is one of the most common symptoms associated with endometriosis. When medical therapy has failed or in known deeply infiltrating endometriosis, surgical management is warranted. Laparoscopy is the gold standard for diagnosis and treatment of endometriosis. Recent developments in surgery have shown the feasibility of robotic surgery for endometriosis, although these methods have not been shown to be superior to conventional laparoscopy...

Narrow-band imaging (NBI) is an optical technique enhancing mucosal vasculature. The aim of this study is to assess the effectiveness of rigid NBI endoscopy in the early detection of second primaries or local recurrences after treatment for oral (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC), its advantage over standard white-light (WL) endoscopy, and the influence of previous radiotherapy, the learning curve, and lesion site. Between January 2013 and June 2015, 195 patients treated for OSCC or OPSCC with surgery alone (group A) or radiotherapy with or without surgery and/or chemotherapy (group B) underwent additional follow-up assessments using NBI...

PURPOSE OF REVIEW: In this review, we summarize the core principles in the management of nonmuscle invasive bladder cancer (NMIBC) with an emphasis on new developments that have emerged over the last year. RECENT FINDINGS: NMIBC has a propensity to recur and progress. Risk stratification has facilitated appropriate patient selection for treatment but improved tools, including biomarkers, are still needed. Enhanced cystoscopy with photodynamic imaging and narrow band imaging show promise for diagnosis, risk stratification, and disease monitoring and has been formally recommended this year by the American Urological Association...

Narrow band imaging (NBI) is widely used in gastrointestinal, laryngeal, and urological endoscopy. Its original purpose was to visualize vessels and epithelial irregularities. Based on our observation that adding NBI to common white light (WL) improves the contrast of the test bolus in fiberoptic endoscopic evaluation of swallowing (FEES), we now investigated the potential value of NBI in swallowing disorders. 148 FEES images were analyzed from 74 consecutive patients with swallowing disorders, including 74 with and 74 without NBI...

In narrow band (NB) laryngeal endoscopy, the clinician usually positions the endoscope near the tissue for a correct inspection of possible vascular pattern alterations, indicative of laryngeal malignancies. The video is usually reviewed many times to refine the diagnosis, resulting in loss of time since the salient frames of the video are mixed with blurred, noisy, and redundant frames caused by the endoscope movements. The aim of this work is to provide to the clinician a unique larynx panorama, obtained through an automatic frame selection strategy to discard non-informative frames...

A 68-year-old man with no symptoms presented to Hokkaido University Hospital for esophagogastroduodenoscopy screening. He had a history of Helicobacter pylori eradication. Initial esophagogastroduodenoscopy showed no gastric cobblestone-like mucosa or gastric cracked mucosa. After 1 year, he received esomeprazole (20 mg) once daily for heartburn at another hospital. Esophagogastroduodenoscopy was performed after 2 years of esomeprazole administration. Endoscopic findings showed that after H. pylori eradication, according to the Kyoto classification, gastric cobblestone-like mucosa presented in the gastric body area...

A man in his 70s received Helicobacter pylori eradication therapy after endoscopic submucosal dissection (ESD) of the stomach. A small, yellowish, protuberant lesion was later observed on the anterior wall of the lower body of the stomach on surveillance esophagogastroduodenoscopy. Narrow band imaging-magnified endoscopy showed an irregular pit and net-like vascular pattern, with the background mucosa having a light blue crest pattern. A biopsy was performed, which led to a diagnosis of adenoma with a gastric phenotype, so repeat ESD was performed...

A 73-year-old woman underwent upper endoscopic screening that revealed a 30-mm superficial elevated lesion in the anterior wall of the upper gastric body. The lesion had a whitish color and coarse granular surface in conventional white light endoscopy. Magnifying narrow-band imaging indicated irregular microvascular and microsurface patterns within a demarcation line. The microvessels had a distorted polygonal shape within the area surrounded by the marginal crypt epithelium. The patient underwent endoscopic resection...

BACKGROUNDS AND AIMS: The Japan NBI Expert Team (JNET) classification is the first universal narrow-band imaging (NBI) magnifying endoscopic classification of colorectal tumors. Considering each type in this classification, the diagnostic ability of Type 2B is the weakest. Generally, clinical behavior is thought to be different in each gross type of colorectal tumor. We evaluated the differences in the diagnostic performance of JNET classification for each gross type (polypoid and superficial) and examined whether the diagnostic performance of Type 2B could improve by subtyping...

Flexible imprinted photonic nanostructures that are able to diffract/focus narrow-band light have potential applications in optical lenses, filters, tunable lasers, displays, and biosensing. Nanophotonic structures through holography and roll-to-roll printing may reduce fabrication complexities and expenses and enable mass production. Here, 3D photonic nanostructures of a stacked ring array were imprinted on acrylate polymer (AP) over poly(ethylene terephthalate) (PET) substrate through holography and lift-off processes to create a microlens array (MLA)...

PURPOSE: Real-time characterization of colorectal lesions during colonoscopy is important for reducing medical costs, given that the need for a pathological diagnosis can be omitted if the accuracy of the diagnostic modality is sufficiently high. However, it is sometimes difficult for community-based gastroenterologists to achieve the required level of diagnostic accuracy. In this regard, we developed a computer-aided diagnosis (CAD) system based on endocytoscopy (EC) to evaluate cellular, glandular, and vessel structure atypia in vivo...
