本文观察γ线照后肠套叠发生与肠运动的关系.实验分正常组、单照组、单烧组、放烧复合伤组.结果观察到各组照后小肠收缩频率无明显改变.6Gy单照组、单烧组和复合伤组在照后不同时间均出现不同程度的肠运动紊乱,除单烧组在伤后第2天有1例套叠外其余各组均未见肠套叠.10Gy照后各组肠运动严重紊乱,强收缩发生率增多,各组肠套叠发生有所增高,单照组为17.3%、复合伤组为25.0%,套叠多发生在照后4～8天,发生部位多在空肠,绝大多数出现套叠的小肠同时伴有运动增强现象.我们认为复合烧伤可以加重肠运动紊乱,使套叠发生率增多.
In this study, we observed the relationship between the occurrence of intussusception and gut motility after γ-ray irradiation.The experimental group was divided into normal group, single control group, single burn group and burn combined burn group.Results There was no significant change in intestinal contraction frequency after 6 weeks The single group, single group and complex injury group showed different degree of intestinal motility disorder at different time after irradiation, except for single burn group on the 2nd day after injury, 1 case had intussusception After 10Gy irradiation, the intestinal motility of each group was severely disturbed, and the incidence of strong contraction increased. The incidence of intussusception in each group was increased, which was 17.3% in the single group and 25.0% in the composite injury group. The incidence of intussusception was 4 ~ 8 days, the occurrence of more sites in the jejunum, the vast majority of intussusception of the small intestine accompanied by increased exercise, we believe that composite burns can aggravate intestinal disorders, the incidence of intussusception increased.
