AIM: To clarify whether antithrombotic drugs affect diagnosis using the immunochemical faecal occult blood test -(iFOBT) of colorectal neoplasia. METHODS: Using the Japan Endoscopy Database from 8 centres between 2015 and 2017, we analyzed data about patients who were iFOBT positive and had received direct oral anticoagulants (DOAC), warfarin, aspirin or thienopyridine. One-to-one matching-analogue propensity score weighted analyses were performed to compare the positive predictive value (PPV) of all neoplasms, invasive and non-invasive colorectal cancers and adenomas between drug users and non-users...

OBJECTIVE: Recent guidelines propose that both proton pump inhibitor (PPI) responders and nonresponders are included in eosinophilic esophagitis (EoE). Although multiple biopsies should be required to diagnose EoE because of patchy distribution of esophageal eosinophils, it is unclear whether multiple biopsies are required to evaluate histological effectiveness of PPI therapy. This study aimed to determine the optimal biopsy protocol after PPI therapy in patients with EoE. METHODS: Of 110 EoE patients, 22 PPI nonresponders were enrolled...

BACKGROUND/AIMS: The aims of the study are to clarify the pathophysiological differences among early chronic pancreatitis (ECP), functional dyspepsia with pancreatic (FD-P) enzyme abnormalities and FD patients and to determine whether camostat mesilate, pancrelipase, and rabeprazole triple therapy improve FD symptoms in the ECP patients and FD-P patients in cross-over way. METHODS: We enrolled 84 consecutive patients presenting with typical symptoms of FD patients (n = 42), ECP patients (n = 15), and FD-P patients (n = 27)...

BACKGROUND: Wilson's disease (WD) is an autosomal recessive disease, which is characterized by an excessive copper accumulation in the liver and brain, leading to subsequent hepatic and/or neurological disorders. The causative gene for WD has been identified as the ATPase Cu2+ transporting beta polypeptide gene (ATP7B), which encodes a protein called copper-transporting ATPase 2. ATP7B mutations may lead to reduced biliary excretion of excess copper and disrupted copper homeostasis, resulting in various clinical symptoms of WD...

BACKGROUND: IgG4-related diseases are a rare but an important entity. Due to the variable clinical presentation, this multiorgan disease was attributed to single-organ systems for many years. Also, it often remains a challenge to differentiate between IgG4-related diseases and malignancies. The pathogenesis seems to be a mixture of Th1- and Th2- immune responses, whereas the role of the non-pathogenic IgG4 antibodies is still unclear. Histopathological characteristics are a lymphoplasmacellular infiltrate with IgG4+ plasma cells, a storiform fibrosis and an obliterative phlebitis...

BACKGROUND/AIMS: There is a heterogeneous subset innate myeloid cells, such as macrophages and dendritic cells, in the human intestinal lamina propria. Several studies have demonstrated that these cells contribute to the maintenance of gut homeostasis through the induction of inflammatory responses and tolerance via cell type-specific mechanisms; whereas, disrupted innate immune responses are implicated in the pathogenesis of Crohn's disease (CD). However, the detailed mechanisms by which each innate myeloid subset regulates gut homeostasis and inflammation largely remain unknown...

Human guts harbor abundant microbes that regulate many aspects of host physiology. However, bacterial imbalance or dysbiosis in the gut due to the dietary or environmental changes may cause colorectal cancer (CRC). Increasing studies show that gut microbiota plays an important role in the occurrence and development of CRC, as a result of virulence factors, bacterial metabolites, or inflammatory pathways. In the future, probiotics or targeting the microbiota will probably be a powerful weapon in the battle against CRC...

BACKGROUND/AIMS: Increased oxidative stress and decreased immune cell apoptosis have been reported to be important factors in the pathogenesis of Crohn's disease (CD). Our aim was to characterize the genetic expression of molecules implicated in the regulation of oxidative stress and apoptosis in peripheral white mononuclear cells of 18 healthy volunteers (controls) and 20 patients at the onset of CD (active CD [aCD]): 10 who achieved remission (inactive CD [iCD]) and 10 who did not present a complete and deep response to treatment (aCD-T)...

BACKGROUND: Gastrointestinal (GI) diseases are known to be largely influenced by one's lifestyle and dietary uptake. A high-salt diet (HSD) is well recognized as a risk factor for cardiovascular complications, hypertension, and metabolic syndromes. However, the relationship between an HSD and the GI system, which is the compartment that comes in direct contact with exogenous stimulants, has not been fully explored. AIMS: We seek to better understand the complexity of the pathogenic effects of an HSD in the context of GI disorders...

BACKGROUND/AIMS: The recently proposed Munich-transarterial chemoembolisation-score (M-TACE) was tailored to suit hepatocellular Carcinoma (HCC) patients evaluated for TACE. M-TACE outperformed the established HCC-staging-systems and successfully passed external validation. Modifications of staging-systems through the rearrangement of stages or by adding prognostic factors are methods of improving prognostic power. M-TACEs performance compared to scores modified this way should be tested...

AIMS: This cross-sectional study is to investigate the presence of Epstein-Barr virus (EBV) in colonic mucosa of inflammatory bowel disease (IBD) patients and its correlation with the clinical disease activities and therapeutic regimens. METHODS: Subjects undergoing colonoscopy for screening of polyps were recruited as control. EBV DNA load was analyzed by means of quantitative real-time polymerase chain reaction and EBV-encoded RNAs were tested by in situ hybridization in intestinal mucosa of IBD patients...

BACKGROUND/AIMS: Settings of structure and color enhancement (CE) change view of white light imaging and a preset low enhancement setting is used regularly. The aim of this study was to investigate whether higher enhancement settings increased colorectal lesions' visibility with endoscopists' visibility scoring and objective color difference (CD) value. METHODS: From April 2015 to September 2015, we analyzed 27 pictures and 100 videos of colorectal lesions. Combinations of structure enhancement (B3, A3, A5) and CE (CE 0, 1, 3) were evaluated and CD values of 2 corresponding modes (high enhancement: A5 + CE3, preset low enhancement: A3 + CE0) were calculated using marketed software...

BACKGROUND/AIMS: No single classification system has so far effectively predicted the severity for Acute Pancreatitis (AP). This study compares the effectiveness of classification systems: Original Atlanta (OAC), Revised Atlanta (RAC), Determinant based classification (DBC), PANC 3, Harmless AP Score (HAPS), Japanese Severity Score (JSS), Symptoms Nutrition Necrosis Antibiotics and Pain (SNNAP), and Beside Index of Severity for AP (BISAP) in predicting outcomes in AP.

METHODS: This single-center retrospective study examined 310 consecutive patients hospitalized with an episode of diverticular disease (cases) and outpatients without a diverticular episode (controls) from January 2012 to December 2015. We investigated distinct clinical factors in hospitalized patients with diverticular bleeding and diverticulitis...

Tilman Sauerbruch, Florence Wong
BACKGROUND: The development of cirrhosis with resultant portal hypertension can lead to oesophageal varices at a rate of 7% per annum. Bleeding from varices happens when the portal pressure is ≥12 mm Hg and can threaten life. SUMMARY: Eliminating the aetiology of cirrhosis is a pivotal step to prevent the formation of varices. In patients with established varices, primary prophylaxis with non-selective beta blockers (NSBB) may slow down the progression of varices and prevent the first variceal bleed...

BACKGROUND: An effective bowel cleanse can improve the imaging quality of video capsule endoscopy (VCE). We aimed to further investigate the optimal small bowel cleanse method by comparing the efficacy of 4 L of clear liquids, 2 L of polyethylene glycol (PEG), and 4 L of PEG on the image quality of VCE. METHODS: A randomized controlled, non-inferiority trial was performed comparing 4 L of clear liquids (Group A), 2 L of PEG (Group B), and 4 L of PEG (Group C). The primary endpoint was image quality between the groups...
