BACKGROUND AND AIM: The dysbiosis of gut microbiota has been reported in acute pancreatitis. However, the direction and magnitude between host microbiota and pancreas remains to be established. This study investigated the association between gut microbiota and acute pancreatitis using Mendelian randomization (MR) methods. METHODS: Summary statistics of gut microbiota abundance and acute pancreatitis were extracted from genome-wide association studies (GWAS). The two-sample bidirectional MR design was employed to assess genetic association between the microbiota and pancreatitis, followed by a comprehensive sensitivity analysis to verify the robustness of the results...

Esophageal varices (EV) in liver cirrhosis carry high mortality risks. Traditional endoscopy, which is costly and subjective, prompts a shift towards machine learning (ML). This review critically evaluates ML applications in predicting bleeding risks and grading EV in patients with liver cirrhosis. Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we conducted a systematic review of studies using ML to predict the risk of variceal bleeding and/or grade EV in liver disease patients...

BACKGROUND AND AIM: We aimed to evaluate comparative outcomes of aggressive versus non-aggressive intravenous fluid (IVF) therapy in patients with acute pancreatitis. METHODS: A systematic search of electronic data sources and bibliographic reference lists were conducted. All randomized controlled trials (RCTs) reporting outcomes of aggressive versus non-aggressive IVF therapy in acute pancreatitis were included and their risk of bias were assessed. Effect sizes were determined for overall mortality, systemic inflammatory response syndrome (SIRS), sepsis, respiratory failure, pancreatic necrosis, severe pancreatitis, clinical improvement, AKI, and length of stay using random-effects modeling...

BACKGROUND AND AIM: The steatosis-associated fibrosis estimator (SAFE) score has been developed to distinguish clinically significant fibrosis in patients with steatotic liver disease (SLD). However, validation of its performance in Asian subjects is limited. This study aimed to evaluate the performance of the SAFE score in Asian subjects with biopsy-proven SLD and in different subgroups according to age, sex, and body mass index. METHODS: We retrospectively analyzed 6383 living liver donors who underwent a liver biopsy between 2005 and 2023...

BACKGROUND AND AIM: Few studies have evaluated the adenoma detection rate (ADR) of colonoscopy with texture and color enhancement imaging (TXI), a novel image-enhancing technology. This study compares the detection of colorectal polyps using TXI to that using white light imaging (WLI). METHODS: This single-center retrospective study used propensity-matched scoring based on the patients' baseline characteristics (age, sex, indication, bowel preparation, endoscopist, colonoscope type, and withdrawal time) to compare the results of patients who underwent chromoendoscopy using WLI or TXI at the Toyoshima Endoscopy Clinic...

BACKGROUND AND AIM: The association between long-term proton-pump inhibitors (PPIs) use and malignancies had long been discussed, but it still lacks consensus. Our study investigated the association between PPI use and hepatocellular carcinoma (HCC) recurrence following curative surgery. METHODS: We retrospectively enrolled 6037 patients with HCC who underwent hepatectomy. Patients were divided into four groups according to their PPI usage. (non-users: < 28 cumulative defined daily dose [cDDD]; short-term users: 28-89 cDDD; mid-term users: 90-179 cDDD, and long-term users: ≥ 180 cDDD, respectively)...

BACKGROUND AND AIM: Several agents are under investigation for nonalcoholic fatty liver disease (NAFLD). We assessed the comparative efficacy of pharmacologic interventions for patients with NAFLD focusing on magnetic resonance imaging (MRI) biomarkers. METHODS: We searched Medline, Embase, and CENTRAL. We included randomized controlled trials of more than 12 weeks of intervention that recruited patients with biopsy-confirmed or MRI-confirmed NAFLD and assessed the efficacy of interventions on liver fat content (LFC) and fibrosis by means of MRI...

BACKGROUND AND AIM: There is no gold standard for making the diagnosis of autoimmune hepatitis (AIH), and the diagnosis of acute onset AIH (A-AIH) is most challenging. A-AIH sometimes develops into acute liver failure with poor prognosis if the diagnosis is delayed. Therefore, it is most important for the better prognosis to diagnose non-severe A-AIH early and treat appropriately. However, features in the early stage of A-AIH are unclear. We examined initial characteristics of non-severe A-AIH in detail and tried to find novel clinical features for the early diagnosis...

BACKGROUND AND AIM: Patients with proton-pump-inhibitor (PPI)-unresponsive reflux symptoms, often caused by functional esophageal disorders (FED), are frequently encountered in clinical practice. We aimed to investigate the prevalence of FED and its associated clinical characteristics in patients with PPI-unresponsive reflux symptoms. METHODS: We retrospectively identified patients who were evaluated for persistent typical reflux symptoms, despite ≥8 weeks of PPI treatment, at the National Taiwan University Hospital from 2014 to 2023...

Although not often discussed, many of the neuromuscular disorders (NMDs) affect the gastrointestinal tract (GIT). Depending on the type of NMD, the prevalence of GIT involvement ranges from <5% (e.g. hereditary neuropathies, myofibrillar myopathies) to 100% (e.g. MNGIE, OPMD). Particularly in NMDs with multisystem affection, involvement of the GIT can dominate the clinical presentation or at least make up a significant part of the clinical picture. The most prominent representatives of NMDs with multisystem involvement are the mitochondrial disorders (MIDs) and the myotonic dystrophies...

BACKGROUND AND AIM: Even with advancement of medical technologies, liver transplantation still faces several major challenges. Hence, other treatment modalities are urgently needed for patients with end-stage liver disease. Stem cells from human exfoliated deciduous teeth (SHED) was discovered to have highly proliferative and pluripotent properties; including differentiation into hepatocyte-like cells. This study aims to investigate the capability of intrasplenic transplanted SHED and SHED-Hep cells in inducing proliferation of stem cells and native hepatocytes in order to accelerate liver regeneration in liver fibrosis mice models...

BACKGROUND AND AIM: Endoscopic ultrasound-guided gastroenterostomy is a procedure used to connect the stomach and dilated afferent loop using a stent under endoscopic ultrasound for afferent loop syndrome. However, the actual efficacy and safety of this procedure remain unclear. Therefore, this retrospective study aimed to evaluate the efficacy and safety of endoscopic ultrasound-guided gastroenterostomy using a laser-cut-type fully covered self-expandable metallic stent and an anchoring plastic stent for afferent loop syndrome...

BACKGROUND AND AIM: Delayed endoscopic sphincterotomy-related bleeding (ES bleeding) is an unavoidable adverse event (AE) that can have serious ramifications. Intraoperative ES bleeding, which stops spontaneously in most cases, is a known risk factor for delayed bleeding. This study aimed to examine the preventive effect of a novel self-assembling peptide (SAP) for delayed ES bleeding in patients who attained spontaneous hemostasis after intraoperative ES bleeding. METHODS: A total of 1507 patients met the eligibility criteria for inclusion in this study...

BACKGROUND AND AIM: Patients with liver cirrhosis often face a grave threat from infected ascites (IA). However, a well-established prognostic model for this complication has not been established in routine clinical practice. Therefore, we aimed to assess mortality risk in patients with liver cirrhosis and IA. METHODS: We conducted a retrospective study across three tertiary hospitals, enrolling 534 adult patients with cirrhotic liver and IA, comprising 465 with spontaneous bacterial peritonitis (SBP), 34 with bacterascites (BA), and 35 with secondary peritonitis (SP)...

BACKGROUND AND AIM: The development of acute pancreatitis (AP) is strongly linked to blood clotting and fibrinolysis issues. Modern clinical practices now utilize advanced blood markers like thrombin-antithrombin III complex (TAT), plasmin-α2-plasmin inhibitor complex, thrombomodulin (TM), and tissue plasminogen activator-inhibitor complex (t-PAIC) to assess thrombosis risk. Our study used a highly sensitive chemiluminescence technique to measure these markers in AP patients, aiming to determine their early predictive value for AP severity...
