# A Comparative Analysis of Laparoscopic Gastrectomy Versus Laparoscopic-Assisted Gastrectomy: The Overall and Disease-Free Survival

## TL;DR

This study compares two surgical techniques for gastric cancer and finds that laparoscopic gastrectomy may improve long-term survival.

## Contribution

The study provides new evidence on the impact of surgical technique on survival outcomes in gastric cancer patients.

## Key findings

- Laparoscopic gastrectomy showed significantly higher 72-month overall survival compared to laparoscopic-assisted gastrectomy.
- Disease-free survival was comparable, but laparoscopic gastrectomy had a marginal advantage.
- Laparoscopic-assisted partial gastrectomy yielded the most favorable survival outcomes in subgroup analyses.

## Abstract

Gastric cancer remains a significant global health challenge with varied survival rates, emphasizing the need for research into effective surgical treatments. In this retrospective study, we compared the 72-month overall and disease-free survival between laparoscopic gastrectomy (LG) and laparoscopic-assisted gastrectomy (AG) in a cohort of 139 patients treated for gastric cancer. The analysis revealed that patients undergoing LG exhibited a significantly higher overall survival rate at 72 months compared to those undergoing AG. Although disease-free survival rates were comparable between the two groups, LG showed a marginal advantage. Subgroup analyses based on the type of gastrectomy and anastomosis demonstrated varied survival probabilities, with laparoscopic-assisted partial gastrectomy yielding the most favorable outcomes. These results highlight the importance of the choice of surgical technique in influencing survival outcomes in gastric cancer.
