目的为了提高对肝癌、总胆管癌、胰腺癌、壶腹癌等消化道恶性肿瘤的认识，减少误诊，以便得到早期诊断和治疗。方法通过７０年代以来被误诊为各型病毒性肝炎２８例消化道癌肿的临床分析。结果发现它们在发病年龄、临床症状、肝脏大小、谷丙转氨酶（ＡＬＴ）定量、黄疸的性质和程度、ｒ－谷氨酰转肽酶（ｒ－ＧＴ）改变以及肝硬化到肝癌等多方面的表现，尽管有不同相似之处，但彼此确有不同的临床特点。结论不同的临床特点和是否存在梗阻性黄疸（尤其肝外梗阻）是区别消化道癌肿和病毒性肝炎的重要根据。
Objective To improve the understanding of liver cancer, common bile duct cancer, pancreatic cancer, ampullary cancer and other digestive tract malignancies and reduce misdiagnosis so as to obtain early diagnosis and treatment. The method has been misdiagnosed as a clinical analysis of 28 cases of various types of viral hepatitis digestive tract cancer since the 1970s. They were found to have multiple aspects of age at onset, clinical symptoms, liver size, ALT levels, the nature and extent of jaundice, changes in r-glutamyl transpeptidase (r-GT), liver cirrhosis, and liver cancer. Performance, despite their similarities, does have different clinical characteristics. Conclusions Different clinical features and the presence or absence of obstructive jaundice (especially extrahepatic obstruction) are important basis for distinguishing gastrointestinal cancer from viral hepatitis.
