Lipopolysaccharides From Non-Helicobacter pylori Gastric Bacteria Potently Stimulate Interleukin-8 Production in Gastric Epithelial Cells.

Background: Gastric acid secretion is compromised in chronic Helicobacter pylori (H. pylori) infection allowing overgrowth of non-H. pylori gastric bacteria (NHGB) in the stomach.

Short-Term Results of Laparoscopic Radiofrequency Ablation Using a Multipolar System for Localized Hepatocellular Carcinoma.

Background And Aim: Multipolar radiofrequency ablation (RFA) is feasible for the treatment of hepatocellular carcinoma (HCC) for which a large ablative area is planned, and it imposes a light physical burden on patients. Multipolar RFA via the percutaneous approach is performed in the majority of cases, but the efficacy of multipolar RFA with a laparoscopic approach has rarely been studied. This study aimed to evaluate the efficacy and safety of multipolar laparoscopic RFA (LRA) for localized HCC over the short term.

A case of small hepatocellular carcinoma treated with laparoscopic multipolar radiofrequency ablation with a no-touch ablation procedure.

A 77-year-old man with hepatocellular carcinoma was admitted to our institution. Computed tomography revealed two nodules, one at the surface and one within the liver, ≤3 cm in diameter. We performed laparoscopic radiofrequency ablation using a bipolar system with a "no-touch ablation" procedure using multiple applicators for insertion, not into the tumor directly, but to the perimeter of the tumor.
