摘要
目的：为了解肝硬化病人胆囊运动功能与自主神经功能及二者的关系。方法：应用超声和心率变异分析技术，分别检测30例肝硬化病人的胆囊运动功能和自主神经功能．结果：与对照组相比：（1）肝硬化组空腹胆囊容积和剩余容积显著增大，胆囊排空时间明显延长，胆囊收缩频率减慢．（2）肝硬化组24小时总频谱功率、极低频频谱功率、低频频谱功率和高频频谱功率均明显降低。（3）肝硬化组高频频谱功率与空腹胆囊容积呈负相关，与胆囊收缩频率呈正相关．结论：肝硬化病人胆囊运动功能障碍可能与自主神经功能异常有关。
Objective:To determine whether impaired autonomic nerve system dysfunctionaffects gallbladder motility in patients with cirrhosis. Methods:gallbladder motor function wasmeasured with real-time ultrasonography and autonomic function was measured with the analysisof heart rate variability in 30 cirrhhotic patients compared with those of normal subjects.Results:(1) basal and residual volumes were significantly higher in cirrhotics than those in controls,and the gallbladder emptying time was markedly prolonged and postprandial gallbladdercontractile frequencies were conspicuously reduced in cirrhotic patients as compared with those ofnormal subjects. (2) Total power, very low frequency power, low frequency power and highfrequency power (HF) were significantly decreased in cirrhotics as compared with those of controls.(3)The cirrhotic patients showed negative correlation between HF and fasting gallbladder volumes(r=-0.44,P<0.05). A correlation was also seen between HF and postprandial gallbladdercontractile frequencies (r=0.62,P<0.001). Conclusion:it is likely that impaired gallbladder motilitymay be related to autonomic nervous system dysfunction in cirrhotics.
