BACKGROUND: The prevalence of constipation in Japan is estimated to be 2-5%. Constipation is a disease found in older adults. In particular, Japan is an aging society, with 65% of men and 80.5% of women aged 65 years or older accounting for the majority of its population. Chronic constipation may be associated with survival, cardiovascular events, decreased quality of life, and death. This study summarizes the recent findings regarding constipation treatment practice in Japan. SUMMARY: Until recently, the diagnosis of constipation was mainly based on medical interviews; however, with the recent development of handheld ultrasound devices, both physicians and nurses can easily and objectively diagnose fecal retention...

BACKGROUND: Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by chronic abdominal symptoms, but its pathogenesis is not fully understood. SUMMARY: We have recently shown in rats that neuropeptides such as orexin, ghrelin, and oxytocin act in the brain to improve the intestinal barrier dysfunction, which is a major pathophysiology of IBS. We have additionally shown that the neuropeptides injected intracisternally induced a visceral antinociceptive action against colonic distension...

INTRODUCTION: The virtual scale endoscope (VSE) is a newly introduced endoscope that helps endoscopists in measuring colorectal polyp size (CPS) during colonoscopy by displaying a virtual scale. This study aimed to determine the usefulness of the VSE for CPS measurement and the educational benefit of using VSE images to improve CPS estimation accuracy. METHODS: This study included 42 colorectal polyps in 26 patients treated at Hiroshima University Hospital. In study 1, CPS measured using a VSE before endoscopic mucosal resection was compared with CPS measured on resected specimens, and the agreement between the two measurement methods was evaluated via Bland-Altman analysis...

INTRODUCTION: Endoscopic full-thickness resection (EFTR) without laparoscopic assistance (pure EFTR) is an emerging, less invasive treatment for gastrointestinal stromal tumors (GISTs). However, the technique has seldom been performed outside China because of concerns regarding pneumoperitoneum, maintenance of endoscopic view, and endoscopic suturing. This study aimed to evaluate the efficacy and safety of endoscopic resection with one-port placement (EROPP) for gastric GISTs. METHODS: This retrospective study included 17 patients with gastric GISTs originating from the muscularis propria who underwent EROPP between 2019 and 2022...

BACKGROUND: Esophageal motility disorders (EMDs) are caused by the impaired relaxation of the upper/lower esophageal sphincter and/or defective esophageal peristaltic contractions, resulting in dysphagia and noncardiac chest pain. High-resolution manometry (HRM) is essential for the diagnosis of primary EMD; however, the recognition of EMD and HRM by general practitioners in Japan is limited. This review summarizes the diagnosis of and treatment strategies for EMD. SUMMARY: HRM is a specific test for the diagnosis of EMD, whereas endoscopy and barium swallow as screening tests provide characteristic findings (i...

INTRODUCTION: Aortic stenosis (AS) is sometimes associated with gastrointestinal bleeding, and this phenomenon is known as Heyde's syndrome. Such bleeding is most often considered to originate from gastrointestinal angiodysplasias, but the frequency and endoscopic features of such bleeding remain unclear. This study aimed to determine the frequency and endoscopic features of gastrointestinal angiodysplasia in patients with severe AS. PATIENTS AND METHODS: In this multicenter, retrospective study, we evaluated consecutive patients who underwent transcatheter aortic valve implantation (TAVI) with severe AS from May 2016 to December 2019...

INTRODUCTION: Submucosal invasion is a core hallmark of early gastric cancer (EGC) with poor prognosis. However, the molecular mechanism of the progression from intramucosal gastric cancer (IMGC) to early submucosal-invasive gastric cancer (SMGC) is not fully understood. The objective of this study was to identify genes and pathways involved in the submucosal invasion in EGC using comprehensive gene expression analysis. METHODS: Gene expression profiling was performed for eight cases of IMGC and eight cases of early SMGC with submucosal invasion ≥500 μm...

BACKGROUND: The 3rd edition of the evidence-based clinical practice guidelines for gastroesophageal reflux disease (GERD) 2021 from the Japanese Society of Gastroenterology states that the treatment strategy for potassium-competitive acid blocker (PCAB)-refractory GERD remains unclear. Furthermore, even if GERD improves with the administration of an acid secretion inhibitor, it is feared that GERD may flare up after discontinuation of the drug, resulting in some cases in which patients are forced to take vonoprazan semipermanently (the so-called PCAB-dependent cases)...

INTRODUCTION: Length of stay (LOS) in hospital affects cost, patient quality of life, and hospital management; however, existing gastrointestinal bleeding models applicable at hospital admission have not focused on LOS. We aimed to construct a predictive model for LOS in acute lower gastrointestinal bleeding (ALGIB). METHODS: We retrospectively analyzed the records of 8,547 patients emergently hospitalized for ALGIB at 49 hospitals (the CODE BLUE-J Study). A predictive model for prolonged hospital stay was developed using the baseline characteristics of 7,107 patients and externally validated in 1,440 patients...

INTRODUCTION: Small bowel tumors (SBTs) are difficult to diagnose because of limited opportunities and technical difficulties in evaluating the small bowel. Asymptomatic conditions or nonspecific symptoms make SBT diagnosis more challenging. In Asia, SBTs are reported to be more frequently malignant lymphoma (ML), adenocarcinoma, and gastrointestinal stromal tumor (GIST). In this study, we examined 66 patients diagnosed with SBTs and determined their clinical characteristics. METHODS: This retrospective study was conducted from January 2013 to July 2020 at Kurume University Hospital...

INTRODUCTION: Esophageal hypersensitivity is associated with gastroesophageal reflux disease (GERD). Since sleep disturbance causes esophageal hypersensitivity, hypnotics may ameliorate GERD. However, zolpidem prolongs esophageal acid clearance. Lemborexant is a new hypnotic with higher efficacy and fewer adverse events than zolpidem. Therefore, the present study investigated the effects of lemborexant on GERD. METHODS: Patients with heartburn and/or regurgitation and insomnia who did not take acid suppressants or hypnotics in the last month were recruited...

BACKGROUND AND AIM: Fluoropyrimidines (FPs) are key drugs in many chemotherapy regimens; however, recipients are often prone to diarrhea due to gastrointestinal toxicity. Disruption of the intestinal epithelial barrier function by FPs leads to dysbiosis, which may exacerbate intestinal epithelial cell damage as a secondary effect and trigger diarrhea. However, despite studies on chemotherapy-induced changes in the intestinal microbiome of humans, the relationship between dysbiosis and diarrhea is unclear...
