Core Tip

Core tip: The impact of body mass index (BMI) on the short-term outcomes of laparoscopic gastrectomy (LG) for gastric cancer in Asian patients have been controversial due to inconsistent results of previous studies. Our meta-analysis demonstrates that despite being associated with longer operative time, greater blood loss, and fewer retrieved lymph nodes, a high BMI could not be significantly associated with short-term outcomes of LG in Asian patients. BMI may be a poor risk factor for short-term outcomes of LG. Other indices should be taken into account.
