大肠癌是常见的消化道肿瘤之一。本病早期缺乏特异症状,难以早期发现;中、晚期病例,虽然症状明显,但也可因警惕性不高而造成误诊。我们对1970～1981年收治,经病理证实误诊的167例,提出讨论,以从中吸取经验教训。 Colorectal cancer is one of the common gastrointestinal cancers. The early stage of the disease lacks specific symptoms and it is difficult to find early. In middle and late cases, although the symptoms are obvious, it may also be misdiagnosed due to poor alertness. We reviewed 167 cases that were diagnosed with pathology and confirmed by pathology from 1970 to 1981. We learned from these lessons and learned lessons from it.
