Noncancerous causes of death, such as cerebrovascular or cardiac disease, are not rare in patients with gastric cancer who had undergone curative gastrectomy. Metabolic syndrome, characterized by visceral fat accumulation, is a risk factor for cerebrovascular and cardiac diseases. However, there is limited information on the effects of reconstruction procedures on changes in visceral fat after distal gastrectomy. The aim of this study was to analyze the impact of the reconstruction procedure (Roux-en-Y reconstruction (RY) and Billroth I reconstruction (BI)) on changes in visceral fat, as determined using computed tomography.


The study subjects were 152 patients with gastric cancer who underwent distal gastrectomy with lymphadenectomy between 2002 and 2007. The visceral fat area was measured for one cross-sectional computed tomogram obtained at the level of the umbilicus.


Adjuvant chemotherapy (yes vs. no, P = 0.0006), type of reconstruction (BI vs. RY, P = 0.0146), field of lymph node dissection (<D2 vs. ≥D2, P = 0.0020), omentectomy (yes vs. no, P = 0.0003), and pathological stage (1/2 vs. 3/4; P = 0.0023) correlated significantly with postoperative visceral fat loss. Multivariate logistic regression analysis identified reconstruction (BI vs. RY; P = 0.0232) and adjuvant chemotherapy (yes vs. no, P = 0.0330) as the significant determinants of visceral fat loss after surgery.


Visceral fat loss after RY was larger than that after BI. Further prospective studies are needed to confirm the effects of reconstruction after distal gastrectomy on visceral fat.
