肝性脑病仍是一个诊断和治疗上的难题。目前对这种疾病的病因了解有限,但对慢性肝病患者肝性脑病的治疗尚称满意。对诱发因素的确定和治疗以及乳果糖的反应仍是最重要的处理方法。特殊肝性营养配方的效果未能在有良好对照的试验中证实。在难治性肝性脑病病人,肝移植已成为一种现实的治疗。 Hepatic encephalopathy is still a diagnostic and therapeutic problem. At present, the etiology of this disease is limited, but the treatment of hepatic encephalopathy in patients with chronic liver disease is still satisfied. The identification and treatment of predisposing factors and the reaction of lactulose remain the most important treatments. The effect of special hepatic nutritional formulas failed to be demonstrated in well-controlled trials. In patients with refractory hepatic encephalopathy, liver transplantation has become a realistic treatment.
