Brief Summary

The purpose of this study is to explore the effect of preoperative hemotologic markers on postoperative long-term and short-term outcomes for laparoscopic gastrectomy.

Detailed Description

A prospective cohort study will be performed to explore the effect of preoperative hemotologic markers on postoperative long-term and short-term outcomes for laparoscopic gastrectomy.The evaluation parameters are perioperative clinical efficacy, postoperative complications and 3-year survival and recurrence rates.
