Background
The postoperative body weight loss in patients with of gastric cancer is one of the most crucial complications, but the composition of the body weight loss is not yet known. Aim of the present study was to describe postoperative changes of body weight, subcutaneous and visceral fat tissue, and abdominal girth in patients with gastric cancer.

Material and Methods
We analyzed eighteen postoperative patients (n=11: distal gastrectomy (DG), n=7: total gastrectomy (TG)) with gastric cancer having no postoperative complications which needed hospital care and chemotherapy. We examined change of postoperative body weight, girth of the abdomen, area of subcutaneous fat and visceral fat by computed tomography one year postoperatively.

Result
The average body weight one year after the operation was lower than before operation in DG andTG (DG: 54.4±10.9 vs 60.4±11.4 kg, TG: 53.7±9.1 vs 60±10.6 kg, p<0.05). Computed tomography revealed the postoperative decrease of the abdominal girth compared to preoperative state (DG: 73.4±7.2 vs 81±7.7 cm, TG 68.5±4.2 vs 78.1±8.7cm, p<0.05). Also area of subcutaneous and visceral fat one year after the operation decreased (p<0.01).

Conclusion
These results indicate the body weight loss with decrease of subcutaneous and visceral fat one year after the operation in patients with gastric cancer.
