In the current era of endoscopic submucosal dissection (ESD) for early gastric cancer, which carries a negligible risk of lymph node metastasis, local resection of the stomach remains an option for these lesions. This is particularly so for a large intramucosal lesion or a lesion with a strong ulcer scar, for which ESD becomes a difficult option. Here, we describe a case of lateral-spreading intramucosal gastric cancer of 6-cm diameter located at the fornix of the stomach, which was successfully treated by laparoscopic and endoscopic cooperative surgery (LECS) because of the expected risk of complications during ESD. In the LECS procedure, the resection margin was appropriately determined by the endoscopic evaluation in detail and by the ESD technique. If early gastric cancer fits the criteria for endoscopic resection but would present difficulty if performing ESD, this is a good indication for the LECS procedure.

Although 7-day P-CAB triple therapy was superior to 7-day PPI triple therapy, neither was highly effective, or can be recommended, in the presence of clarithromycin-resistant infections.

Background:Many micro-RNAs (miRNAs) are differentially expressed in Helicobacter pylori-infected gastric mucosa and in gastric cancer tissue and previous reports have suggested the possibility of serum miRNAs as complementary tumour markers. The aim of the study was to investigate serum miRNAs and pepsinogen levels in individuals at high risk for gastric cancer both before and after H. pylori eradication.Methods:Patients with recent history of endoscopic resection for early gastric cancer and the sex- and age-matched controls were enrolled. Serum was collected from subjects before or after eradication and total RNA was extracted to analyse serum levels of 24 miRNAs. Serum pepsinogen (PG) I and II levels were measured using enzyme-linked immunosorbent assay kits.Results:Using miR-16 as an endogenous control, the relative levels of miR-106 and let-7d before and after H. pylori eradication and miR-21 after eradication were significantly higher in the high-risk group than in the controls. H. pylori eradication significantly decreased miR-106b levels and increased let-7d only in the control group. After eradication, the combination MiR-106b with miR-21 was superior to serum pepsinogen and the most valuable biomarker for the differentiating high-risk group from controls.Conclusion:Serum miR-106b and miR-21 may provide a novel and stable marker of increased risk for early gastric cancer after H. pylori eradication.

Endoscopic biopsy did not increase the bleeding risk despite not stopping antithrombotics prior to biopsy even among patients taking warfarin whose PT-INR was within the therapeutic range.

Co-treatment of ARB reduces peptic ulcer and bleeding among patients taking low dose aspirin. RAS may play an important role in the development of upper GI mucosal injury induced by low dose aspirin.

Dysregulation of specific miRNAs is present in H. pylori-induced corpus gastritis. H. pylori eradication improved miRNA dysregulation, but not in intestinal metaplastic glands or in the gastric mucosa of patients in a high-risk group for gastric cancer.

RAPID(®) 5 Access improves diagnostic yield, reducing reading time; however, it is still unacceptable because of the diagnostic miss rate and may be useful as an ancillary reading tool. Developing further improved software and training expert assistants for reading capsule images are necessary.
