摘要
目的探讨应用过氧化氢增强造影经直肠腔超声诊断复杂性肛瘘的临床应用价值。方法对49例临床确诊为复杂性肛瘘的住院患者分别进行术前常规经直肠腔超声检查和3‰过氧化氢增强造影超声检查,分别观察瘘管内口、主支、分支的位置及数量,将两者结果与术中结果进行比较。结果常规经直肠腔超声与过氧化氢增强造影相比直肠腔内超声对内口的判断准确率分别为32.7%和98.0%(P<0.01);对主支的判断准确率分别为81.6%和100.0%(P>0.05);对分支的判断准确率分别为63.3%和87.8%(P<0.05)。结论过氧化氢增强造影经直肠腔超声较常规经直肠腔超声对复杂性肛瘘的诊断准确率显著提高,有助于为临床治疗方案提供参考。
Objective To objectively evaluate the clinical applications of hydrogen peroxide enhanced transrectal ultrasonography in the diagnosis of complex anal fistula. Methods Fourty-nine patients with complex anal fistula were evaluated by conventional transrectal ultrasound and hydrogen peroxide enhanced transrectal ultrasonography before surgery. The location and number of internal opening, main fistula and branch fistula on two examinations were compared with surgical findings. Results Compared with surgical findings, the diagnostic accuracies of conventional transrectal ultrasound and hydrogen peroxide enhanced transrectal ultrasonography were 32.7% and 98% for identifying the location of internal opening （P〈0.01）, 81.6% and 1（i）0% for identifying the primary tract （P 〉0.05）, 63.3% and 87.8%, for identifying the secondary extensions （P〈0.05）, respectively. Conclusion Hydrogen peroxide enhanced transrectal ultrasonography is superior to conventional transrectal ultrasound in delineating the anatomic pathway of complex anal fistula, which is helpful for surgeon in clinical management.
