Analysis of Intestinal Myoelectric Activity in Patients with Hepatic Cirrhosis / 中国医师杂志

Objective To discuss application value of intestinal electromyography in patients with hepatic cirrhosis and to observe intestinal myoeletric activity.Methods There were 65 cases of hepatic cirrhosis in expermental group and 30 cases in control group. All the cases were recorded body surface intestinal electromyography using gastrointestinal myoelectric analyzer(WCDF-4B, Hefei , P.R.China). The parameters included average peak range-Ap, main frequency-Fp, average over zero frequency-Fz and special wave form were surveyed.Results Sharp higher Fz abnormal rate and emergence rate of special wave form in hepatic cirrhosis group were higher than in control group,P0 05.Conclusions In hepatic cirrhosis group,Fz was much higher than that in control group. And the intestinal myoelectric activity increased in the patients with hepatic cirrhosis,which represented by appearance of characteristic wave form that was frequent micromigration wave as well as load wave. Those changes accounted for heighten and irregularity of excitability intestinal myoelectric activity. Moreover, it will increase for the incidence of abnormality of intestinal myoelectric activity along with damage degree of hepatic function. Intestinal electromyography is a reliable method to judge intestinal myoelectric activity, the method has characteristics of harmless,free pain, convenient, safty and steady.
