Damage of proximal stomach function in diabetic patients / 中华全科医师杂志

ABSTRACT

Fifty four diabetic patients, including 26 cases with dyspepsia and 28 cases without gastrointestinal symptoms, and 21 healthy volunteers were enrolled in this prospective study.To determine the function of proximal stomach, water load test was performed and the area and circumference of gastric corpus were measured by ultrasonography, and the differences between threshold and maximum were calculated.Results showed that the threshold and maximum drinking volumes in diabetic patients with dyspepsia were lower than those without dyspepsia [(638 ±311) ml vs.(870 ±225) ml and(1 000 ±424) ml vs.(1 360 ±322) ml,t=2.779 and 3.111,P<0.05].The threshold drinking volume in patients without dyspepsia was significantly higher than that of control group [ ( 870 ±225 ) ml vs.( 688 ±225 ) ml, t =-2.450, P<0.05].The differences of drinking volume and corpus area in patients with dyspepsia were lower than those of patients without dyspepsia and controls [(362 ±146) ml vs.(490 ±150) ml, (550 ± 157) ml, t=2.838,3.920,(11.76 ±6.85) cm2 vs.(19.78 ±12.07) cm2, (20.80 ±10.65) cm2,t=2.769, 3.311, P<0.05].The difference of circumference in diabetic patients with dyspepsia was lower than in controls [(3.67 ±2.17) cm vs.(6.22 ±3.06) cm, t=3.139,P<0.05].The study indicates that the proximal stomach function is impaired in diabetic patients, presenting a declined sensory threshold and reduced relax function.
