Background:
This study aimed to explore the effect of BMI on intraoperative conditions and postoperative complications (POCs) in robotic GC surgery.
Methods:
This is a retrospective analysis conducted on 60 patients who have GC and received robotic radical gastrectomy (RG) in our hospital. The patients were allocated into normal (18.5 kg/m2 ≤ BMI < 25 kg/m2) and high-BMI groups (BMI ≥ 25 kg/m2). The effect of BMI on intraoperative conditions and POCs was examined.
Results:
The results revealed no statistical differences between both groups in terms of surgical procedure (p = 0.669), time of first postoperative flatus (p = 0.172), in-hospital stay (p = 0.454), Retrieved LNs (Lymph nodes) number (p = 1.000) and POCs (p < 0.05). However, the high BMI group had greater intraoperative bleeding (p = 0.018) and longer operating time (p = 0.016).
Conclusions:
To conclude, BMI may not affect the safety of RG for GC. Nevertheless, high BMI was associated with increased blood loss and prolonged operative time.
