【摘要】 目的 观察肥胖儿伴暴食者、肥胖儿不伴暴食者及正常体质量儿童胃动力学变化，探讨肥胖儿童的胃动力学改变。方法 用实时二维超声观测将20例肥胖儿童伴暴食者、20例肥胖儿童不伴暴食者及20例正常体质量健康儿童的胃动力学表现，对比三者的各项胃动力学指标。结果 超声胃动力学指标： 肥胖儿童伴暴食者、肥胖儿童不伴暴食者以及正常体质量健康儿童的胃窦收缩幅度(△V)分别为(485.54±150.33) mm 2、(405.72±175.40) mm 2和(418.66±145.44) mm 2，胃窦收缩频率(F)分别为(4.80±0.89)次/min、(3.85±0.77)次/min和(3.50±0.86)次/min、胃窦运动指数(MI)分别为(2185.15±656.63)、(1519.46±465.28)和 (1447.66±418.65)，胃窦半排空时间(t1/2)分别为(17.53±3.14)min、(21.53±3.14)min和(22.53±3.14)min，窦排空时间(t)分别为(32.95±11.88)min、(45.37±12.47)min和(46.68±14.18)min。肥胖儿童伴暴食者较正常体质量儿童各项指标差异有统计学意义，其中△V较正常组增大(P<0.05)，F较正常组增加(P<0.05)、MI较正常组增大(P<0.01)，而t1/2、t均较正常组缩短(P<0.05)；而肥胖儿不伴暴食者与正常组的各项指标差异无统计学意义。结论 肥胖儿不伴暴食者与正常体质量儿童胃动力无显著差别，而肥胖儿伴暴食者较正常体质量儿童胃动力显著增高，胃动力改变可能是部分肥胖儿童的发病机制之一。

【Abstract】 Objective To observe the Gastric Emptying rate of the obese children with or without gluttony. Methods The gastric emptying rate were evaluated respectively by real-time ultrasonography in 20 obese children with gluttony and 20 obese children without gluttony and 20 children with normal weight.Gastric motility parameters were compared in there goups.Results Thegastric liquid emptying indexes of obese children with gluttony were significantly quicker than these of others, the respective gastric empyting volume △V of the three groups were (485.54±150.33) mm 2,(405.72±175.40) mm 2 and (418.66±145.44) mm 2 (P<0.05), the gastric contraction rates (F) were (4.80±0.89) times/min,(3.85±0.77) times /min and (3.50±0.86) times/min(P<0.05), the gastric motion index (MI) were (2185.15±656.63), (1519.46±465.28) and (1447.66±418.65) (P<0.01). the halft emptying time (t1/2) were (17.53±3.14)min, (21.53±3.14)min and (22.53±3.14)min (P<0.05), the total emptying time (t) were (32.95±11.88)min, (45.37±12.47)min and (46.68±14.18)min (P<0.05). Conclusion The gastric emptying rate of the obese children with gluttony is quicker than that of obese children without gluttony or children with normal weight. The change of the gastric emptying rate maybe is one of the fators of the obesity in children.
