目的 通过 99m Tc植酸钠固体餐检测胃排空 ,了解功能性消化不良 (functional dyspepsia,FD)患者各临床亚型胃运动的情况 .方法 99m Tc植酸钠标记固体餐 ,对 30例 FD患者 (其中溃疡样型 10例 ,动力障碍型 10例 ,非特异型 10例 )及 10名健康对照者进行了核素检测分析 .结果 运动障碍样型及非特异型 FD患者胃半排空时间延迟 (87± 2 8min,89± 2 6 min vs6 1± 9min,P<0 .0 5 ) ,2 h胃排空率明显减少(6 3.0± 11.5 % ,5 7.7± 15 .5 % vs87.0± 10 .3% ,P<0 .0 1) ,而溃疡样型 FD与正常人比无差异 (P>0 .0 5 ) .结论 胃排空延迟在运动障碍样型及非特异型 FD病因中占重要地位 ,FD三个临床亚型之间发病机制既相同又略有不同 ;FD患者中有症状与胃排空之间存在不一致现象 ,所以核素胃排空检查在 FD胃运动功能的判定及指导治疗上有重要意义 .
Objective To detect gastric emptying in patients with functional dyspepsia (FD) through 99m Tc sodium phytate solid meal.Methods 99m Tc sodium phytate was used to label gastric meal in 30 FD patients (Including 10 cases of ulcer type, 10 cases of motility disorder and 10 cases of nonspecific type) and 10 healthy controls.Results The gastric emptying time of patients with dyskinesia and non-specific FD was delayed (87 ± 28 min, 89 ± 26 min vs6 1 ± 9 min, P <0.05), and the rate of gastric emptying significantly decreased at 2 h (87.0 ± 11.5%, 5 7.7 ± 15.5% vs 87.0 ± 10.3%, P <0.01), while there was no difference between the ulcer-like FD and normal controls (P> 0.05) .Conclusion Delayed gastric emptying may play an important role in the pathogenesis of dyskinesia and non-specific FD The prevalence of FD among the three clinical subtypes of pathogenesis both the same and slightly different; FD patients with symptoms and gastric emptying there is inconsistency, so nuclide gastric emptying in FD gastric motor function determination And guiding the treatment of great significance.
