目的研究胶囊内镜(CE)和多层螺旋CT小肠造影(MSCTE)在小肠血管畸形(vascular malformation,VM)诊断中的价值。方法对36例临床疑似小肠VM患者分别进行CE和MSCTE检查并做出诊断,结合术后病理及临床随访结果,比较两种方法在小肠VM诊断,判断病变范围及并发症等方面的情况。结果 CE与MSCTE对小肠VM确认率相似,两者间差异无统计学意义(χ2=2.29,P>0.05)。两种检查方法对Ⅲ型和Ⅳ型血管VM判断的一致性明显高于对Ⅰ型和Ⅱ型的VM(χ2=11.298,P=0.001)。CE和MSCTE对疾病范围判断的一致性为95.2%。结论 CE可能是确诊小肠VM的首选方法,与MSCTE联合应用有利于诊断和评价小肠VM患者的病情。
Objective To investigate the value of capsule endoscopy (CE) and multislice spiral CT small bowel angiography (MSCTE) in the diagnosis of vascular malformation (VM). Methods Thirty-six patients with clinical suspected small bowel VM were examined with CE and MSCTE, respectively. Combined with postoperative pathology and clinical follow-up results, the two methods were compared in the diagnosis of small bowel VM and the extent of the lesion and complication. Results The confirmation rates of CE and MSCTE in small intestine were similar, but the difference was not statistically significant (χ2 = 2.29, P> 0.05). The consistency between the two methods in judging type III and type IV vascular VM was significantly higher than those in type I and type II VM (χ2 = 11.298, P = 0.001). The consistency of CE and MSCTE in judging the disease range was 95.2%. Conclusion CE may be the method of choice for the diagnosis of small intestine VM. Combined with MSCTE, it is helpful to diagnose and evaluate the condition of small intestinal VM patients.
