Objective Cirrhosis is a most common clinical disease. Child C level is the most severe level in cirrhosis. We try to compare with gastric mucosal lesion seen between cirrhotic patients and the normal people to investigate the electrogastrogram of the patients. Methods Cutaneous electrogastrography was performed in 45 Child C level patients,and 120 healthy volunteers served as normal controls. On the basic of routine protective of treatment, we add probiotics treat cirrhosis, then to analyse electrogastrography. Results In Child C level group, the dominant power ratio was reduced, and before and after meals, the dominant equeney were decreased. The diference was statistically significant between Child C-level patients and the normal controls(P<0. 05). After protiotics treatment for 3 weeks, the dominant power ratio was enhanced, and the doniant equeney, compared with the previous, was increased significantly) P<0. 05). Conclusions The electrogastrogram is abnormal in Child C-level patients,probiotics have a therapeutic effect on gastric motility disorders of liver cirrhosis.
