Enhanced activity of autoimmune gastritis following Helicobacter pylori eradication therapy.

The relationship between autoimmune gastritis (AIG) and Helicobacter pylori (H. pylori) gastritis remains unclear, particularly whether there is any interaction. Herein, we report a case of early-stage AIG diagnosed in an elderly patient with highly active H.

Effects of Medication Period and Gastrin Levels on Endoscopic Gastric Mucosal Changes in Long-Term Proton Pump Inhibitor Users.

: Proton pump inhibitor (PPI) use has increased worldwide, including in continuous and longer-term users. Recent reports highlight PPI-related endoscopic gastric mucosal changes, including fundic gland polyps, hyperplastic polyps, multiple white and flat elevated lesions, cracked and cobblestone-like mucosa (CCLM), and black spots. PPI use elevates gastrin levels because of acid inhibition, and hypergastrinemia might be relevant to these findings.

Predictors of Atherosclerotic Cardiovascular Disease Events in Patients with Metabolic Dysfunction-associated Steatotic Liver Disease.

Objective Metabolic dysfunction-associated steatotic liver disease (MASLD) is a chronic liver disease associated with metabolic comorbidities. However, the risk factors for atherosclerotic cardiovascular disease (ASCVD) in these patients remain unclear. Therefore, this study investigated predictors of ASCVD in patients with MASLD.

Map-Like Redness Development After Eradication Therapy for Helicobacter pylori Infection: Prospective Multicenter Observational Study.

Background: Map-like redness, pathological intestinal metaplasia, is observed in one-fourth to one-third of patients 1 year after Helicobacter pylori eradication therapy, mainly in the corpus, and is a newly identified endoscopic risk factor for gastric cancer development after eradication. However, it is unclear whether intestinal metaplasia is present before eradication at the site where the map-like redness appears. We aimed to identify endoscopic findings that predict the occurrence of map-like redness before H.

Vonoprazan as a Long-term Maintenance Treatment for Erosive Esophagitis: VISION, a 5-Year, Randomized, Open-label Study.

Background & Aims: Acid secretion inhibitors are associated with hypergastrinemia, which can lead to gastric mucosal changes. Potassium-competitive acid blockers, such as vonoprazan, are more potent than proton pump inhibitors, but long-term safety data are lacking.

Methods: In this phase IV, randomized trial, patients with erosive esophagitis (EE) received induction therapy (once daily vonoprazan 20 mg or lansoprazole 30 mg; ≤8 weeks).

Contrast-enhanced ultrasonography combined with superb microvascular imaging for preoperative diagnosis of sporadic intra-abdominal desmoid-type fibromatosis: A case report.

We herein report a case of sporadic intra-abdominal desmoid-type fibromatosis in which contrast-enhanced ultrasonography (US) combined with superb microvascular imaging (SMI) was useful for preoperative diagnosis. 18-Fluorodeoxyglucose positron emission tomography performed for systematic screening for lung cancer revealed an abnormal accumulation in the abdominal cavity. Transabdominal US showed a tumor with a mixture of hypoechoic and hyperechoic areas.

A case of hemorrhagic Meckel's diverticulum diagnosed by transabdominal ultrasound.

A 23-year-old man with a history of anemia of unknown cause was referred to our hospital. He had experienced melena three times: at 6 months, 10 years, and 20 years of age. He underwent upper and lower gastrointestinal endoscopy at 10 and 20 years of age, and small intestinal capsule endoscopy twice at 20 years of age, but the site of bleeding could not be identified.

Diagnostic performance of linked color imaging for gastric cancer by Helicobacter pylori infection status: A subanalysis of the large-scale, multicenter randomized controlled trial LCI-FIND.

Background: Linked color imaging (LCI) is a new image enhancement technology that facilitates the recognition of subtle differences in mucosal color. In the large-scale, multicenter randomized controlled trial LCI-FIND, LCI demonstrated good diagnostic performance for the detection of tumor lesions in the upper gastrointestinal tract. The aim of the present study was to exploratively evaluate the diagnostic performance of LCI according to H.

Multiple gastric neuroendocrine tumors in a patient with parietal cell dysfunction and adenosine triphosphatase H/K transporting subunit alpha gene variant.

A 47-year-old woman presented with multiple gastric tumors, each up to 10 mm in diameter, in the gastric body and fundus without mucosal atrophy. White spots and numerous transparent, light-brownish, small, and rounded spots were observed in the background gastric mucosa. Biopsy specimens obtained from the tumors revealed gastric neuroendocrine tumors.

Different Food Preferences in Patients with Gastrointestinal Disorders.

Objective Gastrointestinal (GI) disorders such as functional dyspepsia (FD), irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), and inflammatory bowel disease (IBD) can exhibit overlapping GI symptoms, including abdominal pain and alterations in bowel habits. The symptoms of GI disorders are commonly considered to be triggered and exacerbated by fatty food intake. Therefore, this study aimed to compare the food preferences of patients with GI disorders.

A Study of the Risk Factors for 402 Patients with Esophageal Squamous Cell Carcinoma - A Retrospective Comparison with Health Checkup Participants.

Objective Esophageal cancer is a gastrointestinal cancer with a poor prognosis. However, it is curable and can be treated endoscopically if it is detected at an early stage. The objective of this study was to identify the factors that contribute to early detection.

Characteristic endoscopic findings in early-stage autoimmune gastritis.

Until recently, autoimmune gastritis (AIG) was usually diagnosed at late stages based on typical endoscopic findings, including corpus-dominant advanced atrophy. Early-stage AIG prior to complete gastric atrophy had rarely been diagnosed due to a lack of knowledge about its endoscopic characteristics. The present study sought to identify the endoscopic characteristics of early-stage AIG, enabling its early diagnosis.

A Case of Idiopathic Peptic Ulcer Disease Treated Effectively with Trimebutine Maleat.

A 30-year-old man with idiopathic peptic ulcer disease (IPUD) experienced repeated recurrence of ulcerative bleeding despite treatment with lansoprazole and then vonoprazan. Further evaluation suggested that the cause of the ulcer was strong contractile movements of the antrum. This prompted the co-administration of trimebutine maleate (TM) and vonoprazan to relieve the stomach contractions.

A case of strangulated bowel obstruction in which transabdominal ultrasound was useful for preoperative diagnosis.

A 74-year-old man presented to the emergency department with the chief complaint of abdominal pain. A computed tomography scan showed paralytic ileus. An ileostomy tube was placed, but the symptoms of bowel obstruction did not improve.

Appendiceal mucocele pathologically classified as appendiceal epithelial hyperplasia and preoperatively diagnosed by contrast-enhanced ultrasonography: A case report.

We report a patient with a mucocele with diffuse wall thickening diagnosed by transabdominal ultrasonography and contrast-enhanced ultrasonography. Transabdominal ultrasonography showed diffuse thickening of the entire appendix wall and an anechoic area that appeared to be fluid collected throughout the appendix lumen. However, the "onion skin sign" was not detected.

A case of nodular gastritis progression to autoimmune gastritis after 10 years of Helicobacter pylori eradication.

A 61-year-old female patient underwent upper gastrointestinal endoscopy, which confirmed the presence of Helicobacter pylori (H. pylori)-positive nodular gastritis (NG). Routine upper gastrointestinal endoscopy after H.

Elobixibat improves rectal sensation in patients with chronic constipation aged ≥60 years: a randomised placebo-controlled study.

Objective: High rectal sensory thresholds (RSTs) are associated with chronic constipation (CC), especially in older patients. Bile acids (BAs) affect the RSTs of healthy individuals. Here, we aimed to investigate the effects of the BA transporter inhibitor elobixibat in patients with CC aged ≥60 years.

A Case of Early Barrett's Adenocarcinoma With Eosinophilic Esophagitis.

A 61-year-old man presented with epigastric pain and underwent upper gastrointestinal endoscopy. A strongly erythematous area was found in the short segment of the Barrett's esophagus, and a biopsy revealed well-differentiated adenocarcinoma. Linear furrows were observed in the lower esophagus, and a biopsy of the lesion revealed eosinophil infiltration of 30 eosinophils per high-power field.

Brain activity in response to food images in patients with irritable bowel syndrome and functional dyspepsia.

Background: Functional dyspepsia (FD) and irritable bowel syndrome (IBS) are caused and exacerbated by consumption of fatty foods. However, no study has evaluated brain activity in response to food images in patients with disorders of gut-brain interaction (DGBI). This study aimed to compare food preference and brain activity when viewing food images between patients with DGBI and healthy controls.

Efficacy of endoscopic ultrasound-guided abscess drainage for non-pancreatic abscesses: A retrospective study.

Background And Aim: Percutaneous drainage of intra-abdominal abscesses is often uncomfortable for the patient and may result in prolonged hospital stays. Recent studies have shown that endoscopic ultrasound-guided abscess drainage (EUS-AD) could effectively treat various abscesses and fluid collections. However, no indications or procedures have been established for EUS-AD treatments, and studies on its usefulness and safety are insufficient.
