Bacteremia and endotoxemia after endoscopic submucosal dissection for gastric neoplasia: pilot study.

Background: Because the invasive procedure of endoscopic submucosal dissection (ESD) entails a large mucosal defect which is left open, with extensive submucosal exposure to the indigenous bacterial flora, the procedure may have a substantial risk for bacteremia. Our aim was to examine gastric ESD-related bacteremia and endotoxemia in gastric neoplasia patients.

Methods: In patients who underwent ESD for superficial gastric neoplasia, blood cultures and plasma endotoxin measurements were done before, immediately after, and on day 2 after ESD.

Magnifying endoscopy with narrow-band imaging achieves superior accuracy in the differential diagnosis of superficial gastric lesions identified with white-light endoscopy: a prospective study.

Background: Conventional, white-light imaging endoscopy (WLE) results in a significant number of misdiagnoses in early gastric cancer. Magnifying endoscopy combined with narrow-band imaging (ME-NBI) is more accurate in the diagnosis of gastric cancer when the diagnostic triad of the disappearance of fine mucosal structure, microvascular dilation, and heterogeneity is used.

Objective: The aim of the present study was to evaluate the superiority of ME-NBI in the differential diagnosis of superficial gastric lesions identified with conventional WLE.

Trimodal imaging endoscopy may improve diagnostic accuracy of early gastric neoplasia: a feasibility study.

Background: A considerable number of superficial gastric neoplasias are overlooked with conventional white light imaging (WLI) endoscopy.

Objective: The aim was to investigate the diagnostic potential of trimodal imaging endoscopy (TME), which combines WLI, autofluorescence imaging (AFI), and narrow-band imaging (NBI), for superficial gastric neoplasia.

Design: Feasibility study.

Ultrathin endoscopy versus high-resolution endoscopy for diagnosing superficial gastric neoplasia.

Background: Ultrathin endoscopy (UTE) is an acceptable and cost-effective alternative to EGD with the patient under sedation, although the diagnostic accuracy of UTE is not well established.

Objective: To compare the diagnostic accuracy of UTE and high-resolution endoscopy (HRE) for superficial gastric neoplasia.

Design: Prospective comparative study.

CpG island hypermethylation of tumor-suppressor genes in H. pylori-infected non-neoplastic gastric mucosa is linked with gastric cancer risk.

Background And Aim: Gastric carcinogenesis involves CpG island hypermethylation (CIHM) of tumor-suppressor genes. Although the CIHM of these genes occurs in non-neoplastic gastric cells, it is unclear whether this epigenetic alteration is linked with aging and/or gastric cancer risk. We investigated this linkage in noncancerous gastric mucosa infected with H.

A 29-year-old man was admitted because of sudden onset of retrograde amnesia. The patient was unable to recall events having occurred during the past 2 years. The impairment was especially serious with regard to personal memories during the 5 months prior to admission, while he had first been working as a full-time employee under stressful circumstance.
