Introduction: Severe and extensive gastric atrophy, extensive or incomplete gastric intestinal metaplasia, and gastric dysplasia are considered high-risk gastric precancerous lesions (HGPLs). Endoscopic findings based on the endoscopic Kyoto classification (EKC) and the Kimura-Takemoto classification (KTC) have been reported to be significantly associated with HGPLs. This study aimed to compare these two classifications in predicting active Helicobacter pylori (H. pylori) infection and HGPLs.
Methods: This is a cross-sectional study conducted on naïve dyspeptic patients who underwent upper gastrointestinal endoscopy at a tertiary hospital. Endoscopic findings were scored according to the EKC and KTC. Mapping biopsies were taken, and H. pylori infection was determined using a locally validated rapid urease test and histology. The performance of EKC was compared with that of KTC using the area under the receiver operating characteristic curve (AUC) in predicting active H. pylori infection and HGPLs.
Results: There were 292 patients with a median age of 46 and a male-to-female ratio of 1:1. The rates of active H. pylori infection and HGPLs were 61.3% and 14.0%, respectively. The EKC was better than the KTC in predicting active H. pylori infection (AUC: 0.771 vs. 0.658, respectively; p < 0.001). However, these two classifications had comparable performance in predicting HGPLs (AUC: 0.792 vs. 0.791, respectively; p = 0.956).
Conclusion: Compared to EKC, KTC is inferior in predicting active H. pylori infection but has comparable performance in predicting HGPLs.

Introduction: Functional status is one of the surrogates of advanced age, an established risk factor for Clostridioides difficile infection (CDI). We aimed to investigate the usefulness of functional status in the clinical management of CDI.
Methods: We enrolled all hospitalized adult patients receiving antibiotics from a retrospective hospital-based cohort in Japan between 2016 and 2020. Using the Barthel index (BI), which is an objective scale of functional status, we investigated the association of BI with developing CDI and its impact on inhospital mortality in patients with CDI.
Results: We enrolled 17,131 patients with 100 cases of CDI. Multivariable analysis revealed that lower BI (≤25) was an independent risk factor for developing CDI (adjusted odds ratio, 4.11; 95% confidence interval, 2.62-6.46). Furthermore, a combination of BI and Charlson comorbidity index (CCI) showed an adjusted odds ratio of 36.40 (95% confidence interval, 17.30-76.60) in the highest risk group. A high-risk group according to the combination of BI and CCI was estimated to have significantly higher inhospital mortality in patients with CDI using the Kaplan-Meier method (p = 0.017). A combination of lower BI and higher CCI was an independent predictor of inhospital mortality even in the multivariable Cox regression model (adjusted hazard ratio, 3.00; 95% confidence interval, 1.01-8.88).
Conclusions: Assessment of functional status, especially combined with comorbidities, was significantly associated with developing CDI and may also be useful in predicting inhospital mortality.

Background: The treatment options for inflammatory bowel disease (IBD) have grown over the last years. However, a significant fraction of patients either do not respond to their treatment or lose response over time.
Summary: Future treatment options could include antibodies that target the tumor necrosis factor-like ligand 1A (TL1A). TL1A is a key cytokine involved in the pathogenesis of a variety of autoimmune diseases including IBD. Studies have shown that IBD disease severity correlates well with serum levels of TL1A. Phase 2 data from two agents currently in clinical testing have been released. In line with requirements for modern therapeutics, companion diagnostic was part of these trials. This aims to identify those patients that are more likely to respond to the agents tested.
Key messages: With regard to the available data the risk/benefit profile of TL1A inhibitors seems to be promising. This article gives a short update and overview, where we are at this point in time with antibodies targeting the TL1A protein in IBD.

Introduction: We conducted an investigator-initiated clinical trial in which remimazolam was used to achieve sedation in patients undergoing colonoscopies.
Methods: This multicenter, double-blind, placebo-controlled, phase III investigator-initiated trial included patients who underwent colonoscopy under sedation with remimazolam (initial dose: 3 mg; additional dose: 1 mg) or normal saline (placebo). The primary endpoint of the study was the successful sedation rate during colonoscopy, defined as achieving a Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score of ≤4 before the procedure, maintaining this score throughout colonoscopy, and requiring no more than five additional drug doses per 15 min.
Results: The sedation success rate was 95.0% (38/40 patients) in the remimazolam group and 0.0% (0/11 patients) in the placebo group (p < 0.01). The time from the end of procedure to regaining consciousness was 0.0 (interquartile range: 0.0-0.0) min in both groups. The time from the end of the procedure to ambulation was 5.0 (interquartile range: 0.0-10.0) min in the remimazolam group and 0.0 (interquartile range: 0.0-0.0) min in the placebo group (p = 0.02). Serious adverse events were not observed.
Conclusion: The use of remimazolam to achieve sedation in Japanese patients undergoing colonoscopy was more effective than placebo.

Introduction: Constipation is one of the most common gastrointestinal symptoms. It may compromise quality of life and social functioning and result in increased healthcare use and costs. We aimed to evaluate the prevalence and risk factors of constipation symptoms, as well as those of refractory constipation symptoms among patients who underwent colonoscopy.
Methods: Over 4.5 years, patients who underwent colonoscopy and completed questionnaires were analyzed. Patients' symptoms were evaluated using the Gastrointestinal Symptoms Rating Scale.
Results: Among 8,621 eligible patients, the prevalence of constipation symptoms was 33.3%. Multivariate analysis revealed female sex (odds ratio [OR] 1.7, p < 0.001), older age (OR 1.3, p < 0.001), cerebral stroke with paralysis (OR 1.7, p = 0.009), chronic renal failure (OR 2.6, p < 0.001), ischemic heart disease (OR 1.3, p = 0.008), diabetes (OR 1.4, p < 0.001), chronic obstructive pulmonary disease (OR 1.5, p = 0.002), benzodiazepine use (OR 1.7, p < 0.001), antiparkinsonian medications use (OR 1.9, p = 0.030), and opioid use (OR 2.1, p = 0.002) as independent risk factors for constipation symptoms. The number of patients taking any medication for constipation was 1,134 (13.2%); however, refractory symptoms of constipation were still present in 61.4% of these patients. Diabetes (OR 1.5, p = 0.028) and irritable bowel syndrome (OR 3.1, p < 0.001) were identified as predictors for refractory constipation symptoms.
Conclusions: Constipation occurred in one-third of patients, and more than half of patients still exhibited refractory symptoms of constipation despite taking laxatives. Multiple medications and concurrent diseases seem to be associated with constipation symptoms.
简介便秘是最常见的胃肠道症状之一。它可能会影响生活质量和社会功能,并导致医疗费用的增加。我们旨在评估接受结肠镜检查的患者中便秘症状的发生率和风险因素,以及难治性便秘症状的发生率和风险因素:我们对 4.5 年来接受结肠镜检查并填写问卷的患者进行了分析。结果:在 8621 名符合条件的患者中,有 1.7% 的人有便秘症状:在8621名符合条件的患者中,便秘症状的发生率为33.3%。多变量分析显示,女性(几率比 [OR] 1.7,P <0.001)、老年(OR 1.3,P <0.001)、脑中风伴瘫痪(OR 1.7,P = 0.009)、慢性肾功能衰竭(OR 2.6,P <0.001)、缺血性心脏病(OR 1.3,P = 0.008)、糖尿病(OR 1.4, P < 0.001)、慢性阻塞性肺病(OR 1.5, P = 0.002)、苯二氮卓类药物的使用(OR 1.7, P < 0.001)、抗帕金森病药物的使用(OR 1.9, P = 0.030)和阿片类药物的使用(OR 2.1, P = 0.002)为便秘症状的独立危险因素。服用任何药物治疗便秘的患者人数为 1,134 人(13.2%),但其中 61.4% 的患者仍存在难治性便秘症状。糖尿病(OR 1.5,P = 0.028)和肠易激综合征(OR 3.1,P < 0.001)被认为是预测难治性便秘症状的因素:结论:三分之一的患者出现便秘,超过一半的患者在服用泻药后仍表现出难治性便秘症状。多种药物和并发疾病似乎与便秘症状有关。

Introduction: Carbazochrome sodium sulfonate (CSS) is a hemostatic agent that reduces capillary permeability and enhances capillary resistance. However, its specific effects on colorectal endoscopic submucosal dissection (ESD) outcomes remain uncertain. This study aimed to assess the risk factors for post-ESD bleeding and the effect of CSS on colorectal ESD outcomes.
Methods: First, we retrospectively analyzed the risk factors for post-ESD bleeding using data from 1,315 lesions in 1,223 patients who underwent ESD for superficial colorectal neoplasms at eight institutions. Second, patients were divided into CSS and non-CSS groups using propensity score matching, and their outcomes from colorectal ESD were analyzed.
Results: The risk factors for post-colorectal ESD bleeding were identified as age of ≥70 years, tumor located in the rectum, tumor size of ≥40 mm, and post-ESD defect unclosure in both univariate and multivariate analyses. The CSS and non-CSS groups each consisted of 423 lesions after propensity score matching. The post-colorectal ESD bleeding rate was 3.5% (15/423) and 3.3% (14/423) in the CSS and non-CSS groups, respectively, indicating no significant differences. Among patients with the high-risk factors for post-ESD bleeding, the administration of CSS also did not demonstrate a significant reduction in the post-ESD bleeding rate compared to the non-CSS group.
Conclusion: CSS administration is ineffective in preventing post-colorectal ESD bleeding in both the general population and individuals at a high risk for such bleeding. Our results indicate the necessity to reconsider the application of CSS for preventing post-colorectal ESD bleeding.

Introduction: Functional dyspepsia (FD) is a chronic relapsing gastroduodenal disorder with limited treatment options. Herbal products, like the six-herb combination STW 5-II, can target multiple FD gastrointestinal symptoms. In this meta-analysis, we evaluated the efficacy and safety of STW 5-II for overall FD, and key symptoms, based on Rome IV criteria.
Methods: We systematically screened the literature for randomized controlled clinical studies testing STW 5-II in FD. Meta-analysis was performed using data from individual patients with at least one key FD symptom (fullness, early satiety, or epigastric pain) of at least moderate severity at baseline. ANCOVA-based meta-analyses were performed on improvements in the total symptom sum score, and single symptoms, after 4 and 8 weeks. Safety data were analyzed by calculating odds ratios for all adverse events.
Results: Four randomized controlled trials, including 613 patients, were identified, and two were eligible for efficacy analysis. STW 5-II significantly improved the FD symptom sum score (mean difference of 1.74 after 4 weeks and 2.07 after 8 weeks) and key FD symptoms of fullness (0.28 and 0.29), early satiety (0.25 and 0.26), and epigastric/upper abdominal pain (0.26 and 0.3). Treatment-related or severe adverse events did not differ between STW 5-II and placebo.
Conclusion: The results support that STW 5-II significantly improves FD symptoms after 4 and 8 weeks of treatment with no difference in relation to safety signals compared to placebo. Thus, STW 5-II can be considered an effective and safe treatment option for FD.

Background: Functional dyspepsia (FD) is a common disorder characterized by chronic or recurrent upper abdominal pain or discomfort without any structural abnormalities in the gastrointestinal tract. FD is categorized into two subgroups based on symptoms: postprandial distress syndrome (PDS) and epigastric pain syndrome.
Summary: The pathophysiology of FD involves several mechanisms. Delayed gastric emptying is observed in approximately 30% of FD patients but does not correlate with symptom patterns or severity. Impaired gastric accommodation is important in the pathophysiology, particularly for PDS. Visceral hypersensitivity, characterized by heightened sensitivity to normal activities, contributes to the perception of discomfort or pain in FD. Alterations to the duodenal mucosa, including impaired mucosal barrier function and low-grade inflammation, are also implicated in the pathogenesis of FD. Microbial dysbiosis and psychological factors such as stress can further exacerbate symptoms. Treatment options include dietary modifications, establishing a physician-patient relationship, acid suppressants, prokinetics, neuromodulators, and behavioral therapies. Dietary recommendations include eating smaller, more frequent meals, and avoiding trigger foods. Acid suppressants are used as the first-line treatment. Prokinetics and neuromodulators aim to improve gastric motility and central pain processing, respectively. Behavioral therapies, including cognitive behavioral therapy and hypnotherapy, have shown benefits for refractory FD. Severe and refractory cases may require combination therapies or experimental treatments.
Key messages: FD is a disorder of gut-brain interaction involving diverse pathophysiological mechanisms. Individualized treatment based on symptoms and responses to interventions is crucial. Further research is needed to improve the understanding of FD and advance the development of effective therapies.

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.e., esophageal rosette and bird's beak sign) in some cases. It is important to note that manometric diagnoses apart from achalasia are often clinically irrelevant; therefore, the recently updated guidelines suggest additional manometric maneuvers, such as the rapid drink challenge, and further testing, including functional lumen imaging, for a more accurate diagnosis before invasive treatment. Endoscopic/surgical myotomy, pneumatic dilation, and botulinum toxin injections need to be considered for patients with achalasia and clinically relevant esophagogastric junction outflow obstruction.
Key message: Since the detailed pathophysiology of EMD remains unclear, their diagnosis needs to be cautiously established prior to the initiation of invasive treatment.

Introduction: 5-aminosalicylic acid (5-ASA) is the first-line drug for the treatment of mild-to-moderate ulcerative colitis (UC). Three oral sustained-release formulations are often used. However, no unified view of their actual use in routine medical practice has been presented to date.
Methods: Using a health insurance claims database, we extracted patients with an initial diagnosis of mild-to-moderate UC during the period from December 1, 2017, to March 31, 2022. For the three types of oral 5-ASA formulation, we calculated and compared descriptive statistics of medication persistence rates (MPR), proportions of days covered (PDC), and adherence proportion (PDC ≥80%) in the extracted population.
Results: An oral 5-ASA formulation was used in combination with a topical preparation (cohort 1) in 899 patients, and oral 5-ASA was used alone (cohort 2) in 1,829 patients. In cohort 1, MPR at days 151-180 with concomitant use of topical formulation was significantly higher for the Multi Matrix System™ (MMX) formulation (65.2%) compared with that for pH-dependent formulation (51.7%, p < 0.025), while MPR tended to be higher for MMX than for the time-dependent formulation (56.4%, not significant). During days 151-180 after starting the oral formulation, MPR for MMX (66.7% and 65.8%) was higher than for pH-dependent (55.9% and 55.3%) and time-dependent (57.6% and 55.9%) formulations in cohorts 1 + 2 and 2, respectively. In cohort 1, there was a significant difference between MMX (68.3%) and pH-dependent (57.1%) formulations, but no significant difference was seen with time-dependent formulations (61.8%). In terms of the proportion of adherence until day 180, MMX was significantly better than the other formulations.
Conclusion: The analyses of the three oral 5-ASA formulations suggested that both MPR and medication adherence were better for the MMX formulation than for time-dependent or pH-dependent formulations.
