【摘要】：目的探讨核磁共振成像技术(MRI)诊断术后肛周深部感染性病变的临床价值,为术后肛周深部感染性病变的诊断提供参考。方法选取2015年1月-12月医院诊治的拟诊为术后肛周脓肿的患者60例,行MRI检查,与手术结果进行比较。结果 60例术后肛周深部感染性疾病,56例为单纯肛周深部脓肿,4例为肛周深部脓肿合并瘘管,共有68个脓腔,60个内口,其中脓腔32个在坐骨直肠间隙、24个在骨盆直肠间隙、12个在高位括约肌间,分别占47.06%、35.29%、17.65%,脓腔形态31个为不规则条块、20个为类圆形、17个为分叶状,构成比分别为45.59%、29.41%、25.00%,54例为单房、6例为多房脓肿,构成比分别为90.00%、10.00%;MRI诊断出56例为单纯肛周深部脓肿,4例为肛周深部脓肿合并瘘管,诊断准确率为100.00%,诊断出65个脓腔,53个内口,坐骨直肠间隙、骨盆直肠间隙、高位括约肌间脓腔诊断准确率分别为100.00%、91.67%、91.67%,与手术确诊比较差异无统计学意义,内口诊断准确性为88.33%低于手术确诊,差异有统计学意义(P0.05)。结论 MRI诊断术后肛周深部感染性病变准确率高,清晰显示脓肿及内口所在位置及脓腔数目、瘘管走形等特征,可为病情诊断及手术提供重要指导信息。
[Abstract]:Objective to evaluate the clinical value of magnetic resonance imaging (MRI) in the diagnosis of deep perianal infectious diseases after operation. Methods from January to December 2015, 60 patients with perianal abscess who were diagnosed as postoperative perianal abscess were selected and examined by MRI. Results 56 cases of postoperative deep perianal infectious diseases were simple deep perianal abscess, 4 cases were deep perianal abscess with fistula, there were 68 purulent cavities and 60 internal orifices. Of these, 32 were in the ischiorectal space, 24 in the pelvic and rectal space, 12 in the high sphincter, accounting for 47.06 and 35.290.29 and 17.65 respectively. The shape of the pus cavity was irregular in 31, round in 20, and lobular in 17. The compositional ratios were 45.599.41 and 25.00 respectively. There were 54 cases of single chamber and 6 cases of multilocular abscess. The composition ratio was 90.0010. 00% respectively. MRI diagnosed 56 cases of pure deep abscess around anus 4 cases of deep abscess around the anus with fistula, the diagnostic accuracy was 100.0000,65 cases of pus cavity, 53 internal mouth, 56 cases of deep abscess around anus with fistula. The diagnostic accuracy of ischiorectal space, pelvic rectal space and high sphincter sepsis were 100.00and 91.67, respectively. There was no significant difference compared with surgical diagnosis, and the accuracy of internal orifice diagnosis was 88.33% lower than that of surgical diagnosis. Conclusion the accuracy of MRI in the diagnosis of postoperative deep perianal infectious diseases is high, the location of abscess and internal mouth, the number of pus cavity and the shape of fistula can be clearly displayed, which can provide important guiding information for the diagnosis and operation of the disease.
