克隆氏病是一种原因不明的非特异性肠道炎症。1932年Crohn等首先在回肠末端发现病变,定名为局限性回肠炎。以后发现消化道任何部位都可受累,因此又名局限性肠炎。本病的病理变化以肉芽肿性增生为主,故又名肉芽肿性肠炎,但不少病例缺乏肉芽肿病变,所以仍称克隆氏病较妥。本病国内少见,可能是临床上未被足够重视。现将本院20年(1957～1976)间收治的28例加以分析。 Crohn’s disease is a non-specific intestinal inflammation of unknown cause. In 1932, Crohn et al. first discovered lesions at the end of the ileum, which was named Crohn’s disease. Later found that any part of the digestive tract can be involved, it is also known as localized enteritis. The pathological changes of the disease are mainly granulomatous hyperplasia. It is also known as granulomatous enteritis. However, many cases lack granulomatous lesions, so Crohn’s disease is still considered more appropriate. The disease is rare in the country and may not be given sufficient clinical attention. We will analyze 28 cases admitted to our hospital during the 20th year (1957-1976).
