We earlier reported that mucosal defect involving over three-fourths of the circumference esophagus after endoscopic resection (EMR) is a risk factor for development stricture. Although balloon dilation (EBD) useful procedure to relieve stricture, there no standard strategy preventing The aim this study was evaluate efficacy and safety preventive EBD.From 1993 2008, 41 consecutive patients with extensive esophageal EMR or submucosal dissection (ESD) were investigated. Preventive EBD carried...

Summary Background The presence of abnormal microcapillaries detected by narrow band imaging (NBI) with magnifying colonoscopy has been reported to be a marker colorectal neoplasia. Aim To investigate prospectively if NBI magnification could help predict the histology early Methods A series 104 consecutive patients 139 lesions were studied. All conventional and subsequently evaluated magnification. During magnification, microvascular architecture observed on surface lesions, capillary...

Circulating microRNAs (miRNA) are emerging as promising diagnostic biomarkers for colorectal cancer, but their usefulness detecting early neoplasms remains unclear. This study aimed to identify serum miRNA the identification of patients with neoplasms.A cohort 237 samples from 160 (148 precancerous lesions and 12 cancers) 77 healthy subjects was analyzed in a three-step approach that included comprehensive literature review published biomarkers, screening phase, validation phase. RNA...

Background and Aim The Japan narrow‐band imaging (NBI) Expert Team (JNET) was organized to unify four previous magnifying NBI classifications (the Sano, Hiroshima, Showa, Jikei classifications). JNET working group created criteria (referred as the scale) for evaluation of vessel pattern (VP) surface (SP). We conducted a multicenter validation study scale develop classification colorectal lesions. Methods Twenty‐five expert colonoscopists read 100 still images with without magnification on...

Early detection of gastric cancer has been the topic major efforts in high prevalence areas. Whether advanced imaging methods, such as second-generation narrow band (2G-NBI) can improve early detection, is unknown.This open-label, randomised, controlled tandem trial was conducted 13 hospitals. Patients at increased risk for were randomly assigned to primary white light (WLI) followed by secondary 2G-NBI (WLI group: n=2258) and WLI (2G-NBI n=2265) performed same examiner. Suspected (EGC)...

Abstract Duodenal cancer is considered to be a small intestinal carcinoma in terms of clinicopathology. In Japan, there are no established treatment guidelines based on sufficient scientific evidence; therefore, daily clinical practice, the experience individual physicians. However, with advances diagnostic modalities, it anticipated that opportunities for its detection will increase future. We developed duodenal because this disease have high medical need from both healthcare providers and...

BACKGROUND Colorectal cancer (CRC) is a global health concern, with advanced-stage diagnoses contributing to poor prognoses. The efficacy of CRC screening has been well-established; nevertheless, significant proportion patients remain unscreened, > 70% cases diagnosed outside screening. Although identifying specific subgroups for whom should be particularly recommended crucial owing limited resources, the association between diagnostic routes and identification these less appreciated. In...

We reviewed the magnifying observation of microvascular architecture colorectal lesions and discuss utility detailed for differential diagnosis during narrow‐band imaging (NBI) colonoscopy. Angiogenesis is critical to transition premalignant in a hyperproliferative state malignant phenotype. Therefore, based on angiogenic or vascular morphologic changes might be ideal early detection neoplasms. In this review, we propose term ‘meshed capillary’ distinction between non‐neoplastic neoplastic...

Propagation path losses affecting intervehicle communication (IVC) at 60 GHz are presented. In order to examine the radio-propagation characteristics in IVC system, first stage of our investigation, we have carried out propagation tests between two vehicles communicating a line-of-sight (LOS) situation fixed positions on smooth surface paved with asphalt, which is normal condition. Furthermore, non-LOS (NLOS) up three intermediate vehicles, can cause an obstruction, has been conducted. To...

Abstract Objectives Although accurate assessment of polyp morphology helps endoscopists select the appropriate management for colorectal polyps, some studies have reported unsatisfactory accuracy in such assessment. This study aimed to clarify usefulness a short educational video available on Internet Methods was multicenter randomized controlled trial. Participants were randomly assigned pre‐ or post‐education groups after pre‐test comprising images 42 including 12 laterally spreading...
