BACKGROUND: Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) meeting the expanded indication is considered investigational. We aimed to compare long-term outcomes of ESD and surgery for EGC in the expanded indication based on each criterion. METHODS: This study included 1823 consecutive EGC patients meeting expanded indication conditions and treated at a tertiary referral center: 916 and 907 patients underwent surgery or ESD, respectively. The expanded indication included four discrete criteria: (I) intramucosal differentiated tumor, without ulcers, size >2 cm; (II) intramucosal differentiated tumor, with ulcers, size ≤3 cm; (III) intramucosal undifferentiated tumor, without ulcers, size ≤2 cm; and (IV) submucosal invasion <500 μm (sm1), differentiated tumor, size ≤3 cm...

BACKGROUND: Gastric mucosal defect could result from several causative factors including the use of nonsteroidal anti-inflammatory drugs, Helicobacter pylori infection, gastrointestinal and spinal cord diseases, and neoplasia. This study was performed to achieve a novel simple, inexpensive, and effective surgical technique for the repair of gastric mucosal defect. METHODS: Six adult male mongrel dogs were divided into two groups (three dogs each). In the control positive group (C + ve), dogs were subjected to surgical induction of gastric mucosal defect and then treated using traditional medicinal treatment for such a condition...

BACKGROUND AND AIM: Radiation-induced colitis is a common clinical problem associated with radiotherapy and accidental exposure to ionizing radiation. Goblet cells play a pivotal role in the intestinal barrier against pathogenic bacteria. Rebamipide, anti-gastric ulcer drug, has the effects to promote goblet cell proliferation. The aim of this study was to investigate whether radiation-induced colonic injury could be alleviated by rebamipide. METHODS: We orally administered rebamipide for 6 days to mice, which were subjected to 13 Gy abdominal irradiation, to evaluate the therapeutic effects of rebamipide against radiation-induced colitis...

Temporomandibular joint osteoarthritis (TMJ-OA) is a degenerative disease that involves changes in subchondral bone and progressive degradation of cartilage. Currently, rebamipide, a gastroprotective drug, is administered to protect gastric mucosa and accelerate ulcer healing. Recent studies have shown that rebamipide also attenuates cartilage degeneration by suppressing oxidative damage and inducing homeostasis of the extracellular matrix of articular chondrocytes. Regarding the latter, reduced expression of cathepsin K, NFATc1, c-Src, and integrin β3, and increased expression of nuclear factor-kappa B, have been found to be mediated by the transcription factor, receptor activator of nuclear factor kappa-B ligand (RANKL)...

Adenosine diphosphate P2Y12 receptor antagonist clopidogrel is not sufficiently safe for the gastric mucosa in patients with high risk of peptic ulcer, since it may impair healing of gastric erosions. However, the safety of the novel P2Y12 receptor antagonist ticagrelor in the gastric mucosa has not been elucidated to date. The present study aimed to examine whether ticagrelor delays gastric ulcer healing and to elucidate the involved mechanisms. Gastric kissing ulcers were produced in rats by luminal application of acetic acid solution, and ticagrelor was administered at dose of 10 or 20 mg/kg/day orally for 7 days...

BACKGROUND: The brain and gastrointestinal (GI) tract are strongly connected via neural, endocrine, and immune pathways. Previous studies suggest that headaches, especially migraines, may be associated with various GI disorders. However, upper GI endoscopy in migraineurs has shown a low prevalence of abnormal findings. Also, the majority of studies have not demonstrated an association between Helicobacter pylori (HP) infection and migraine, although a pathogenic role for HP infection in migraines has been suggested...

Helicobacter pylori has been identified as one of the major causes of chronic gastritis, gastric and duodenal ulcers, and gastric cancer. Lipopolysaccharide (LPS) is a major component of the outer membrane of gram-negative bacteria, and H. pylori LPS might play an exclusively important role in activating inflammatory pathways in monocytes and macrophages. To study the role of LPS in the underlying mechanism of inflammatory responses, we established an in vitro model using the human AGS gastric cancer cell line...

Carbohydrate antigen 19-9 (CA19-9) is a well-known tumor marker for pancreatobiliary cancer, and several studies have shown that an elevated serum CA19-9 level is associated with more aggressive biological behavior in gastric cancer (GC). However, the clinicopathological characteristics of CA19-9-positive GC remain unclear. We herein report an autopsy case of CA19-9-positive GC in an 84-year-old man who was admitted to our hospital because of paralysis and anemia. Autopsy revealed an ulcerative-invasive tumor measuring 72 × 60 mm in the anterior wall of the gastric body...

BACKGROUND: Helicobacter pylori is a pathogen that causes inflammation in the gastric mucosa, and may lead to a peptic ulcer, perforation, or malignancy. Children are at risk of contracting H. pylori and developing subsequent morbidity. In children, diagnosis and management are difficult and merit a different approach than with adults. OBJECTIVE: To describe resistance rates of H. pylori to antibiotics such as amoxicillin, tetracycline, clarithromycin, metronidazole, levofloxacin, and Rifampicin...

A series of novel quinolines incorporating 1,2,4-triazole/oxime hybrids were prepared. They showed remarkable anti-inflammatory activity and exhibited very low incidence of gastric ulceration, compared to indomethacin. Most of the compounds tested showed remarkable inhibition of the COX-1 isozyme, with IC50's ranging from 0.48 to 28µM. Compounds 7c and 9g showed high safety profiles with normal stomach tissue integrity. Docking studies supported the observed in vitro inhibitory activity towards the COX enzymes that may explain their promising anti-inflammatory activity relative to indomethacin...

INTRODUCTION: Gastric lipomas are unusual benign lesions and account for less than 1% of all tumours of the stomach and 5% of all gastrointestinal lipomas (Thompson et al.2003; Fernandez et al. 1983 [1,2]). Although predominantly asymptomatic and indolent; they may present with gastric outlet obstruction and upper gastrointestinal (GI) bleeding owing to size and ulceration. Only a few cases have been reported, presenting large in size with massive GI bleeding (Alcalde Escribano et al...

BACKGROUND: Understanding immune phenotypes and human gastric disease in situ requires an approach that leverages multiplexed immunohistochemistry (mIHC) with multispectral imaging to facilitate precise image analyses. METHODS: We developed a novel 4-color mIHC assay based on tyramide signal amplification that allowed us to reliably interrogate immunologic checkpoints, including programmed death-ligand 1 (PD-L1), cytotoxic T cells (CD8(+)T) and regulatory T cells (Foxp3), in formalin-fixed, paraffin-embedded tissues of various human gastric diseases...

Helicobacter pylori is a pathogen involved in gastric diseases such as ulcers and carcinomas. H. pylori's urease is an important virulence factor produced in large amounts by this bacterium. In previous studies, we have shown that this protein is able to activate several cell types like neutrophils, monocytes, platelets, endothelial cells, and gastric epithelial cells. Angiogenesis is a physiological process implicated in growth, invasion and metastization of tumors. Here, we have analyzed the angiogenic potential of H...

Studies have indicated that the definitive engraftment and transdifferentiation potential of stem cells does not seem crucial for its property of tissue repair. Our previous study showed that transplantation of adipose-derived mesenchymal stem cells (ADMSCs) enhanced the healing of sutured gastric perforation. This study aimed to investigate the paracrine role of ADMSCs in the experimental gastric mucosal injury. Normoxia-conditioned medium (Nor CM) and hypoxia (HPO) CM were obtained after culturing ADMSCs in 20% O2 and 5% O2 for 48h...

OBJECTIVES: Differentiating ulcerative colitis (UC) and Crohn's disease (CD) can be clinically challenging, especially in children. Granulomatous inflammation has traditionally been attributed to CD. Crypt-associated giant cells and granulomas, however, have been observed in colonic biopsies of UC patients. This phenomenon has not been described in the upper gastrointestinal (UGI) tract with UC. METHODS: Seven pediatric UC patients with granulomatous UGI (gUGI) lesions were identified...

Gastric cancer is a leading cause of cancer‑associated mortality worldwide. In studies on the mechanisms of antigastric cancer drugs, autophagy and endoplasmic reticulum (ER) stress have been demonstrated to serve an active role in gastric cancer. The organic extract of Periplaneta americana (also termed American Cockroach), which is named Kangfuxin (KFX) in China, has been used clinically as a traditional Chinese medicine against disorders, including stomach bleeding, gastric ulcers, tuberculosis, burns and trauma...

We experienced a case of intestinal strongyloidiasis complicated by jejunal carcinoma. A Japanese male in his 50s, who has a 7-year medical history of duodenal ulcers, complained of loss of appetite, nausea, vomiting and diarrhea. Computed tomography and gastroduodenal endoscopic examination revealed a stenosis of the duodenum. To remove the stenosis, gastric bypass surgery was performed. The pathological diagnosis of the resected jejunum was strongyloidiasis and well-differentiated adenocarcinoma with subserosal invasion and vascular infiltration...
