BACKGROUND/OBJECTIVES: No prospective study on the long-term effects of gastric resection on gastrointestinal hormonal changes in patients with normal body weight has been reported. The aim of this study was to evaluate the 1-year effect of subtotal gastrectomy on ghrelin and peptide YY (PYY)(3-36) levels.
SUBJECTS/METHODS: Eighteen patients with early gastric cancer underwent subtotal gastrectomy with Billroth I reconstruction. We assessed appetite, food intake, body composition, and ghrelin and PYY(3-36) levels preoperatively and 1 year after surgery.
RESULTS: There were no significant difference in the preoperative daily food intake and 1 year after subtotal gastrectomy. Weight loss occurred in all study subjects; 11.7% (n=2), 55.5% (n=10) and 33.3% (n=6) of the patients lost <5%, 5-10% and >10% of their preoperative body weight, respectively. Body mass index, waist circumference and body fat significantly decreased 1 year after subtotal gastrectomy. There were no significant differences in the appetite visual analogue scale preoperatively and 1 year after subtotal gastrectomy. The plasma ghrelin concentration decreased significantly (P=0.006), whereas PYY(3-36) did not show a significant change 1 year after subtotal gastrectomy.
CONCLUSIONS: Ghrelin levels and body fat decreased significantly, whereas PYY(3-36) levels as well as appetite and food intake did not change significantly 1 year after subtotal gastrectomy with normal body weight. These findings suggest that decreased ghrelin might contribute directly to reduced body fat.
