目的总结活动期溃疡性结肠炎(UC)的多层螺旋CT肠道造影(CTE)特点,探讨多层螺旋CTE在全面评估UC中的价值。资料与方法 35例经临床、肠镜及病理证实的活动期UC患者,均行多层螺旋CTE检查,根据改良Mayo评分系统将疾病分为轻度、中度、重度,比较不同组的CTE表现。结果 35例UC患者中,轻度组6例,中度组13例,重度组16例,轻度组与中度组肠黏膜下气泡差异有统计学意义(P<0.05),中度组与重度组肠壁分层、结肠袋消失及淋巴结肿大差异有统计学意义(P<0.05),肠系膜血管增多在3组间差异均有统计学意义(P<0.05),肠壁增厚、黏膜强化程度增加、肠腔狭窄及直肠周围脂肪沉积在各组间差异无统计学意义(P>0.05)。结论多层螺旋CTE可以全面评估UC的肠壁、肠管及肠外情况,对活动期UC的诊断及临床分度判断均有较高的价值。
Objective To summarize the characteristics of multislice spiral CT in active ulcerative colitis (UC) and to evaluate the value of multislice helical CTE in the comprehensive evaluation of UC. Materials and Methods 35 patients with active UC confirmed by clinical, colonoscopy and pathology were examined by multi-slice CTE. According to the modified Mayo scoring system, the patients were divided into mild, moderate, severe and comparatively different groups of CTE . Results Among the 35 patients with UC, there were 6 cases in mild group, 13 cases in moderate group and 16 cases in severe group. There was significant difference in gas bubbles in intestinal mucosa between mild group and moderate group (P <0.05) Severe group of intestinal wall stratification, disappearance of the colon bag and lymph node enlargement was statistically significant (P <0.05), mesenteric vessels increased in the three groups were statistically significant differences (P <0.05), thickening of the intestinal mucosa There was no significant difference between groups in the degree of enhancement, intestinal stenosis and peri-rectal fat deposition (P> 0.05). Conclusions Multi-slice helical CTE can fully evaluate the intestinal wall, bowel and parenteral conditions of UC, and is of great value in the diagnosis and clinical classification of active UC.
