Objective To investigate the clinical feature and misdiagnosis of 128 patients with Wilson’s disease and proposed the points of diagnosis for this disease. MethodsOne hundred and twenty eight patients with Wilson’s disease from Jan. 1983 to Apr. 2000 of our hospital were reviewed. Their clinical feature and diagnosis condition, such as the first onset symptoms, misdiagnosis conditions and hypersplenism were studied. Results①The first onset symptoms: 64 showed liver dysfunction and 52 presented manifestation of central nerves system (CNS) (Pgt;0.05). ②The age of liver dysfunction was significantly younger (13 years) than that of CNS involved patients (23 years, P＜0.05). ③Patients with the liver damage had enlarged liver (3 cm below the right rib) and hypersplenism and 12 patients had to receive splenectomy. ④Gastroscopy or barium meal showed that esophageal varicose rate was 30.8%（12/39） and 7 patients had large upper gastrointestinal bleeding. Conclusion The age of liver involved patients is significantly younger than that of the CNS involved patients. The liver cirrhosis, hypersplenism and portal hypertension are very common complications of Wilson’s disease and some prevention and cure measures should be taken for these complications.
