【摘要】 目的：分析研究術(shù)前MRI定位技術(shù)對于復(fù)雜性肛瘺手術(shù)的臨床效果。方法：選取80例2017年2月-2018年5月筆者所在醫(yī)院收治的復(fù)雜性肛瘺患者，隨機分為對照組和研究組，兩組均40例。對照組采用亞甲藍染色技術(shù)進行手術(shù)，研究組采用MRI定位技術(shù)確定瘺管相關(guān)情況，然后根據(jù)瘺管走向和內(nèi)口進行手術(shù)，比較分析兩組術(shù)中發(fā)現(xiàn)內(nèi)口數(shù)量、手術(shù)次數(shù)、愈合時間和治療效果。結(jié)果：研究組發(fā)現(xiàn)的內(nèi)口數(shù)量顯著多于對照組，手術(shù)次數(shù)顯著少于對照組，且差異均有統(tǒng)計學(xué)意義（P<0.05）;雖然研究組的愈合時間較對照組短，但兩組比較差異無統(tǒng)計學(xué)意義（P>0.05）。研究組的治療率高達92.50%，顯著高于對照組的72.50%，差異有統(tǒng)計學(xué)意義（P<0.05）。結(jié)論：術(shù)前MRI定位技術(shù)應(yīng)用于復(fù)雜性肛瘺手術(shù)的臨床效果顯著，值得推廣。

[Abstract] Objective： To analyze the clinical effect of preoperative MRI localization technique for complex anal fistula operation. Method： From February 2017 to May 2018， 80 patients with complex anal fistula admitted to our hospital were randomly divided into the control group and the research group， with 40 cases in each group. The control group was operated with methylene blue staining technique， while the study group was operated with MRI localization technique to determine the fistula-related situation. Then， according to the fistula direction and the internal orifice， the operation was carried out. The number of internal orifices found， the number of operations， the healing time and the therapeutic effect were compared and analyzed between the two groups. Result： The number of internal orifices found in the study group was significantly more than that in the control group， the number of operations was significantly less than that in the control group， and the differences were statistically significant （P<0.05）. Although the healing time of the study group was shorter than that of the control group， but there was no significant difference between the two groups （P>0.05）. At the same time， the treatment rate of the study group was 92.50%， which was significantly higher than 72.50% of the control group （P<0.05）. Conclusion： The application of preoperative MRI localization technique in complex anal fistula surgery has a significant clinical effect and is worth popularizing.

復(fù)雜性肛瘺是一種臨床上常見的直腸肛管疾病，由瘺管、內(nèi)口和外口組成，該病自愈的可能性較小且會間歇性發(fā)作[1-2]。復(fù)雜性肛瘺患者的臨床表現(xiàn)主要是瘺管中形成膿腫，劇烈疼痛，膿腫破潰形成外瘺口或切開引流后癥狀有所緩解[3]。但是當(dāng)外瘺口假性愈合時會再次形成膿腫，加劇疼痛，反復(fù)發(fā)作，臨床上多采用手術(shù)治療[4]。復(fù)雜性肛瘺手術(shù)成功與否的關(guān)鍵是要正確評估瘺管的走向和內(nèi)口位置，同時要處理好內(nèi)口、支管和病變組織，因此，術(shù)前的診斷尤為重要[5]。基于此，本研究對術(shù)前MRI定位技術(shù)用于復(fù)雜性肛瘺手術(shù)的臨床效果進行了分析研究，以期為提高復(fù)雜性肛瘺手術(shù)的成功率提供參考，現(xiàn)報道如下。
