Clinical significance and impact of gastric non-Helicobacter pylori Helicobacter species in gastric disease.

Background: Gastric non-Helicobacter pylori Helicobacter (NHPH) species naturally associated with animals have been linked with gastric disease in human patients.

Aim: The prevalence and clinical significance of zoonotic gastric NHPHs was determined in large and well-defined, H. pylori-negative, gastric patient populations.

Laparoscopic liver resection for colorectal liver metastases: retrospective analysis of prognostic factors and oncological outcomes in a single-center cohort.

Purpose: Laparoscopic liver resection (LLR) has gained acceptance as an effective treatment for colorectal liver metastases (CRLM) in selected patients, providing similar oncologic outcomes compared to open liver resection (OLR). The aim of this study was to determine prognostic factors for survival outcomes associated with LLR for CRLM.

Methods: A single-center retrospective analysis of a prospectively maintained database was performed.
