title: Metabolic effects of gastrectomy with or without omentectomy in gastric cancer.
abstract: OBJECTIVE
  The metabolic effects of gastrectomy and the reduction of visceral adiposity through omentectomy for gastric cancer are unknown.
  
  
  METHODS
  We retrospectively reviewed of prospectively collected data of 67 patients over one year who underwent radical gastrectomy with either a complete or partial omentectomy for gastric cancer. The change in Body mass index (BMI), triglyceride, low density lipoprotein, high density lipoprotein, and hematological profile were evaluated.
  
  
  RESULTS
  In the group of 67 patients changes were observed after 1 year follow-up for BMI (23.7±3.1 versus 21.3±2.5kg/m2; p<0.001), triglyceride (155.2±136.1 versus 89.7±41.2mg/dL, p=0.011), low density lipoprotein (107.4±45.4 versus 95.8±27.5mg/dL, p=0.020), vitamin B12 (681.4±297.4 versus 558.1±338.6pg/mL, p=0.076). High density lipoprotein (41.4±12.6 versus 52.8±10.5mg/dL) increased after surgery (p<0.001). There were no changes between the complete and partial omentectomy groups for BMI, albumin, triglyceride, lipoprotein, and hemoglobin.
  
  
  CONCLUSIONS
  Gastrectomy with or without omentectomy induced a decrease of BMI and improvements in metabolic parameters such as triglyceride, low density lipoprotein, high density lipoprotein. Omentectomy had no significant impact on any measured parameter in this group.
