尼日利亚伊巴丹大学医院对20～40岁的125名男性和75名女性蛔虫病患者进行了钡餐腹部X线透视和摄影,并对其中200例的照片进行了分析。在这200例中,小肠腔内见有蛔虫成虫者53例(26.5%)。在这53例中,48例(92.2%)的小肠部位有病征。认为成虫的毒性产物和/或释出的变态反应原可引起:(1)变态反应或成虫对其附近粘膜的直接影响而发生局部病变;(2)由于毒性产物吸入粘膜下层淋巴管而导致粘膜组织的疾 The University of Ibadan Hospital in Nigeria performed barium abdomen radiography and radiography on 125 men aged 20-40 years and 75 women with ascariasis. The photographs of 200 patients were analyzed. In these 200 cases, there were 53 cases (26.5%) of roundworm adults in the small intestine. Of the 53 cases, 48 ​​(92.2%) had small bowel lesions. It is thought that adult toxic products and / or released allergens may cause: (1) a local lesion due to an allergic reaction or an adult’s immediate effect on the mucosa nearby; (2) mucosal damage due to inhalation of toxic products into the submucosal lymphatic vessels Organizational disease
