摘要
目的探讨LAVA动态增强扫描及后处理技术诊断肛瘘的价值。方法选择35例肛瘘患者,分别采用直肠腔内B超、MRI平扫、LAVA动态增强扫描进行诊断;对肛瘘内口、瘘管路径、脓肿位置以及Parks分型进行分析,比较不同诊断技术的符合率。结果直肠腔内B超对肛瘘内口位置的检出符合率最高,为92.11%;其次是LAVA动态增强扫描,检出率为50.00%,MRI平扫检出率为21.05%,差异均有统计学意义(P<0.05)。LAVA增强扫描对瘘管路径和数目的检出率为97.67%,明显高于直肠腔内B超的76.74%和MRI平扫的72.09%,差异具有统计学意义(P<0.05)。LAVA增强、MRI平扫对脓肿位置和数目的检测率均为100%,明显高于直肠腔内B超的61.54%,差异具有统计学意义(P<0.05)。结论 LAVA动态增强扫描诊断肛瘘能够提高瘘管路径和数目以及对肛瘘分型的术后符合率,而对肛瘘内口位置和数目检测与直肠腔内B超比较处于劣势。在对肛瘘的诊断中应用LAVA增强扫描结合直肠腔内B超优势互补,以满足手术方案的设计,减少术后并发症,降低复发率。
ObjectiveTo investigate the dynamic enhanced LAVA scanning and postprocessing technique in the diagnosis of anal fistula. MethodsThirty five patients with anal fistula were chosen, and diagnosed by B-ultrasound, MRI scan, and dynamic enhanced LAVA scanning, respectively; The inside mouth of anal fistula、location of abscess and Parks types were analyzed,and the coincidence rate were compared between different techniques. ResultsTransrectal ultrasonography for position of the inside mouth of anal fistula has the highest rate of 92.11%, followed by LAVA dynamic contrast-enhancement with the rate of 50.00%, and MRI routine scan with the rate of 21.05%; the difference was statistically significant （P〈0.05）. LAVA dynamic contrast-enhancement for the fistula path and number has the highest detection rate of 97.67%, higher than 76.74% of transrectal ultrasonography and 72.09% of MRI routine scan; the difference was statistically significant （P〈0.05）. LAVA dynamic contrast-enhancement and MRI routine scan for location and number of abscess had the detection rate of 100%, higher than 61.54% transrectal ultrasonography; the difference was statistically significant （P〈0.05）. ConclusionLAVA dynamic contrast-enhancement can improve the diagnosis of path and number for fistula, and increase the coincidence rate of postoperative for fistula type, but has a disadvantage in the detection of the inside mouth of anal fistula position and number, compared with transrectal ultrasonography. The diagnosis of anal fistula should combine with LAVA dynamic contrast-enhancement and transrectal B-ultrasound together, to meet the design of operation, decrease the postoperative complications and reduce the relapse rate.with LAVA dynamic contrast-enhancement and transrectal B-ultrasound together, to meet the design of operation, decrease the postoperative complications and reduce the relapse rate.
