Dis Colon Rectum. 1984 Jan;27(1):10-5. doi: 10.1007/BF02554063.
Two hundred thirty-two cases of colorectal malignancy were studied between January 1975 and March 1981. The material was analyzed with respect to various epidemiologic features such as age, sex, residence, religion, socioeconomic status, diet, bowel habits, site of bowel involved, acute obstructive symptoms, and histopathology. The disease afflicted predominantly old people but at an age earlier than is reported in most western studies. Rectal cancer was more common in males, while colonic cancer involved the two sexes equally. Acute large-bowel obstruction was found in 19.4 per cent of patients. The rectum was the most common site (41.8 per cent). Of all the colonic malignancies, 63.4 per cent were in the right colon. Simultaneously, normal gut transit studies using radiopaque markers were conducted in 30 healthy volunteers. The colonic transit rate was 3.09 cm/hour. The markers had a faster gut transit but, interestingly, exhibited pronounced stasis in the right colon, which correlates well with the significantly higher incidence of right-sided malignancy.
1975年1月至1981年3月期间，对232例结肠直肠癌病例进行了研究。对该材料进行了分析，涉及各种流行病学特征，如年龄、性别、居住地、宗教、社会经济地位、饮食、排便习惯、受累肠段部位、急性梗阻症状和组织病理学。该疾病主要影响老年人，但发病年龄比大多数西方研究报告的要早。直肠癌在男性中更为常见，而结肠癌在两性中发病率相同。19.4%的患者出现急性大肠梗阻。直肠是最常见的部位（41.8%）。在所有结肠恶性肿瘤中，63.4%位于右半结肠。同时，对30名健康志愿者进行了使用不透射线标志物的正常肠道转运研究。结肠转运速度为每小时3.09厘米。标志物的肠道转运速度更快，但有趣的是，在右半结肠表现出明显的淤滞，这与右侧恶性肿瘤的显著更高发病率密切相关。
