To assess agreement between endoanal sonography, endoanal magnetic resonance (MR) imaging, and surgery in depiction and classification of fistula in ano.
Twenty-eight consecutive patients with nonspecific, cryptoglandular fistula in ano were studied. The fistulas were classified with endoanal sonography, endoanal MR imaging, and surgery. Agreement between the modalities was also evaluated.
Classification of fistulas was possible in 17 of 28 patients (61%) with sonography, in 25 of 28 (89%) with MR imaging, and in 26 of 28 (93%) with surgery. Concordance between endoanal sonography and MR imaging occurred in 46% of the cases (kappa = 0.27, poor agreement); between sonography and surgery in 36% (kappa = 0.09, no agreement); and between MR imaging and surgery in 64% (kappa = 0.43, moderate agreement).
Endoanal MR imaging more accurately allows depiction and classification of fistula in ano than endoanal sonography.
评估肛管内超声、肛管磁共振成像（MR）及手术在肛管肛瘘的显示及分类方面的一致性。
对28例连续性非特异性、隐窝腺源性肛管肛瘘患者进行研究。通过肛管内超声、肛管MR成像及手术对肛瘘进行分类，并评估这些检查方法之间的一致性。
28例患者中，17例（61%）可通过超声对肛瘘进行分类，25例（89%）可通过MR成像分类，26例（93%）可通过手术分类。肛管内超声与MR成像之间的一致性为46%（kappa = 0.27，一致性差）；超声与手术之间的一致性为36%（kappa = 0.09，无一致性）；MR成像与手术之间的一致性为64%（kappa = 0.43，中度一致性）。
与肛管内超声相比，肛管MR成像能更准确地显示及分类肛管肛瘘。
