    Abstract:
    OBJECTIVE: To study the change of the serum gastrin (GAS) and plasma motilin (MTL) levels as well as the gastric motility in gastric cancer patients after subtotal gastrectomy. METHODS: We used radioimmunoassay method to detect the levels of serum GAS and plasma MTL in 39 healthy volunteers (control group) and 39 gastric cancer patients before and after gastrectomy (gastric cancer group). Electrogastrography (EGG) was measured at the same time points. RESULTS: The levels of serum GAS and plasma MTL in gastric cancer group before operation were significantly higher than those in control group (P = 0.000), and the levels of serum GAS and plasma MTL in gastric cancer stage II patients were also significantly higher than those in stage III patients (P <0.05). The levels of serum GAS and plasma MTL in gastric cancer group significantly decreased on the first post-operative day (P = 0.000), but returned to the pre-operative levels on the seventh post-operative day. The incidence of the abnormity of gastric motility in gastric cancer group on the seventh post-operative day was significantly higher than the pre-operation incidence (89.7% vs. 43.6%; chi2 = 18.692, P <0.01). CONCLUSIONS: The levels of serum GAS and plasma MTL transiently decreased in gastric cancer patients. Subtotal gastrectomy could affect the gastric motility in gastric cancer patients.
