目的探究腹部增强CT检查在粘连性肠梗阻中的诊断价值。方法 90例粘连性肠梗阻患者行腹部增强CT和X线平片检查,比较不同检查方法的诊断准确率并观察粘连性肠梗阻患者的CT征象。结果腹部X线平片检查诊断粘连性肠梗阻准确率为90%(81/90),增强CT结果诊断准确率为98.89%(89/90),增强CT诊断的准确率高于X线平片,差异具有统计学意义(χ^2=7.843,P<0.05)。扩张/塌陷肠管相连、肠管扩张≥25 mm CT征象在90例粘连性肠梗阻患者中的出现率最高。结论相比腹部X线平片,腹部增强CT诊断粘连性肠梗阻的准确率较高,有助于粘连性肠梗阻的临床早期诊断。
Objective To evaluate the clinical efficacy of enhanced CT for abdominal examination in the diagnosis of adhesive intestinal obstruction. Methods Firstly,90 patients with adhesive intestinal obstruction were subjected to abdominal examination with enhanced CT and X-ray plain film respectively. The rates of accurate diagnosis of the two Methods were compared and the CT signs of the patients with adhesive intestinal obstruction were examined. Results The rate of accurate diagnosis by X-ray film was 90%( 81/90) and that by enhanced CT was 98.89%( 89/90),which was higher than that by X-ray plain film. The difference was statistically significant( χ^2= 7. 843,P < 0. 05). The number of findings by CT of intestinal connection due to expansion or collapse of the tracts and bowel dilatation ≥25 mm was the greatest among 90 patients with adhesive intestinal obstruction. Conclusions Compared with X-ray plain film,enhanced CT for abdominal examination warrants even higher rate of accurate diagnosis of adhesive intestinal obstruction and thus can serve as an efficient technology for early diagnosis of adhesive intestinal obstruction.
