Background Although submucosal dissection is useful for treating laterally spreading colorectal tumors, there is little information regarding the endoscopic treatment of large protruding colorectal neoplasms. Here, we aimed to evaluate the clinical outcomes of endoscopic submucosal dissection for protruding colorectal neoplasms ≥ 20 mm in diameter. Methods In total, 112 consecutive patients undergoing treatment between January 2005 and June 2017 were enrolled retrospectively. The study period was divided into six periods to evaluate any changes in outcomes over time...

Background and aim:  The depth of tumor invasion is currently the only reliable predictive risk factor for lymph node metastasis before endoscopic treatment for colorectal cancer. However, the most important factor to predict lymph node metastasis has been suggested to be lymphovascular invasion rather than the depth of invasion. Thus, the aim of this study was to investigate the predictive relevance of lymphovascular invasion before endoscopic treatment. Methods:  The data on pT1 colorectal cancers that were resected endoscopically or surgically from 2007 to 2015 were retrospectively reviewed...

BACKGROUND: Familial adenomatous polyposis (FAP) is a rare, autosomal dominant disease clinically characterized by the early onset of many adenomatous polyps throughout the colon, which turn into colon cancer, if left untreated. In FAP patients, polyps can also occur in the upper gastrointestinal (GI) tract, especially in the duodenum. Adenomas beyond duodenum are rare and mostly located in the proximal jejunum and distal ileum. The management of such polyps can be either surgical or endoscopic, depending on the features of the polyp, Spigelman stage and patient's clinical conditions...

Endoscopy imaging of the gastrointestinal (GI) tract has evolved tremendously over the last few decades. Key milestones in the development of endoscopy imaging include the use of various dyes for chromoendoscopy, the application of optical magnification in endoscopy, the introduction of high-definition image capturing and display technology and the application of altered illuminating light to achieve vascular and surface enhancement. Aims of this review paper are to summarize the development and evolution of modern endoscopy imaging and in particular, imaged-enhanced endoscopy (IEE), to promote appropriate usage, and to guide future development of good endoscopy practice...

OBJECTIVES: We propose a new systematic approach in bifurcation lesions, modified jailed balloon technique (M-JBT), and report the first clinical experience. BACKGROUND: Side branch occlusion brings with a serious complication and occurs in more than 7.0% of cases during bifurcation stenting. METHODS: A jailed balloon (JB) is introduced into the side branch (SB), while a stent is placed in the main branch (MB) as crossing SB. The size of the JB is half of the MB stent size...

BACKGROUND: Historically, humoral immunity was considered unimportant in anti-tumor immunity, and the differentiation and anti-tumor activity of B cells in breast cancer are poorly understood. However, it was recently discovered that B cells participate in tumor immunity through both antibody production and immunosuppressive mechanisms. We analyzed the expression of B-cell differentiation markers in detail using fluorescence-activated cell sorting to investigate the relationship between B-cell subsets and breast cancer etiology...

The management of duodenal and colorectal tumours is important in patients with familial adenomatous polyposis (FAP). Endoscopic resection (ER) should be carefully performed because the risk of complications during or after (ER) of nonampullary duodenal tumours is higher than that of stomach or colorectal lesions in general. Thus, we evaluated the feasibility of endoscopic resection using bipolar snare (ERB) for nonampullary duodenal tumours in FAP patients. Eleven FAP patients who underwent ERB for nonampullary duodenal tumours at our hospital between October 2013 and December 2016 were retrospectively analysed based on clinicopathological features...

BACKGROUND: When performing endoscopic submucosal dissection (ESD), procedural safety increases with greater tissue elevation and efficiency increases with longer-lasting submucosal cushion. Fluids specifically developed for ESD in Asia aren't commercially available in the West, leading endoscopists to use a variety of injectable fluids off-label. To determine the optimal fluid available in the West, we compared commonly used fluids for Western ESD. METHODS: All phases were performed in an ex-vivo porcine stomach model...

BACKGROUND: Respiratory tract infection is a major cause of acute exacerbation of bronchial asthma (AEBA). Although recent findings suggest that common bacteria are causally associated with AEBA, a comprehensive epidemiologic analysis of infectious pathogens including common/atypical bacteria and viruses in AEBA has not been performed. Accordingly, we attempted to detect pathogens during AEBA by using real-time polymerase chain reaction (PCR) in comparison to conventional methods. METHODS: We prospectively enroled adult patients with AEBA from August 2012 to March 2014...

BACKGROUND: In Japan, the rate of cervical cancer screening is remarkably low, especially among women in their twenties and thirties, when cervical cancer is now increasing dramatically. The aim of this study was to test whether a modified government reminder for 20-year-old women to engage in cervical cancer screening, acting through maternal education and by asking for a maternal recommendation to the daughter to receive the screening, could increase their participation rate. METHODS: In two Japanese cities, 20-year-old girls who had not received their first cervical cancer screening before October of fiscal year 2014 were randomized into two study arms...

Whether patients with severe aortic stenosis (AS) die because of AS-related causes is an important issue for the management of these patients. We used data from CURRENT AS registry, a Japanese multicenter registry, to assess the causes of death in severe AS patients and to identify the factors associated with non-cardiac mortality. We enrolled 3815 consecutive patients with a median follow-up of 1176 days; the 1449 overall deaths comprised 802 (55.3%) from cardiac and 647 (44.7%) from non-cardiac causes. Heart failure (HF) (25...

Water in a nanoconfined geometry has attracted great interest from the viewpoint of not only basic science but also nanofluidic applications. Here, the rotational dynamics of water inside single-walled carbon nanotubes (SWCNTs) with mean diameters larger than ca. 1.4 nm were investigated systematically using (2)H nuclear magnetic resonance spectroscopy with high-purity SWCNTs and molecular dynamics calculations. The results were compared with those for hydrophilic pores. It was found that faster water dynamics could be achieved by increasing the hydrophobicity of the pore walls and decreasing the pore diameters...

We hypothesized that along with exercise, casein peptide supplementation would have a higher impact on improving glucose tolerance than intact casein. Male six-week-old ICR mice were provided a high-fat diet to induce obesity and glucose intolerance. The mice were randomly divided into four treatment groups: control (Con), endurance training (Tr), endurance training with intact casein supplementation (Cas+Tr), and endurance training with casein peptide supplementation (CP+Tr). The mice in each group were orally administrated water, intact casein, or casein peptide (1...

BACKGROUND: Clinical profiles of acute heart failure (AHF) complicating severe aortic stenosis (AS) remain unclear.Methods and Results:From a Japanese multicenter registry enrolling consecutive patients with severe AS, 3,813 patients were categorized into the 3 groups according to the symptom of heart failure (HF); No HF (n=2,210), chronic HF (CHF) (n=813) and AHF defined as hospitalized HF at enrolment (n=790). Median follow-up was 1,123 days with 93% follow-up rate at 2 years. Risk factors for developing AHF included age, female sex, lower body mass index, untreated coronary artery stenosis, anemia, history of HF, left ventricular ejection fraction <50%, presence of any combined valvular disease, peak aortic jet velocity ≥5 m/s and tricuspid regurgitation pressure gradient ≥40 mmHg, and negative risk factors included dyslipidemia, history of percutaneous coronary intervention and hemodialysis...
