Hypothesis
Does obesity affect intraoperative bleeding volume in open gastrectomy with D2 lymph-node dissection for gastric cancer?
Conclusion
High BMI and visceral fat area are associated with increased intraoperative blood loss during D2 gastrectomy.
Supporting Evidence
- Patients with high BMI had significantly greater intraoperative blood loss compared to those with normal BMI.
- Visceral fat area was a significant predictor of intraoperative blood loss.
- Age and type of gastrectomy also influenced blood loss during surgery.
Takeaway
Being overweight can make surgery harder and lead to more bleeding. Doctors need to be extra careful when operating on heavier patients.
Methodology
100 patients with gastric cancer underwent open gastrectomy; their BMI and visceral fat area were assessed to evaluate their impact on intraoperative blood loss.
Potential Biases
Potential selection bias due to the specific patient population and surgical techniques used.
Limitations
The study only included patients from one institution and may not be generalizable to all populations.
Participant Demographics
72 men and 28 women, aged 36 to 85 years (mean age 66.0 years).
