摘要:
目的探讨合并直肠炎与未合并直肠炎患者肛周克罗恩病的MRI影像特征差异。方法回顾性分析2017年9月—2021年7月扬州大学附属医院及南京中医药大学附属医院57例肛周克罗恩病患者临床资料，均于入院1个月内进行结肠镜检查及肛周MRI检查。根据患者炎症是否累及直肠分为直肠炎组和非直肠炎组，分别测量直肠壁厚度、直肠壁的表观扩散系数(apparent diffusion coefficient, ADC)、直肠壁的T2信号强度，是否高位瘘管内口（瘘口位于直肠视为高位），有无肛提肌上瘘管，有无肛提肌上脓肿。结果独立样本t检验示直肠炎与非直肠炎组直肠壁厚度及ADC值差异均存在统计学意义（P<0.001）；χ2检验示直肠炎组T2信号中-重度增高比率显著高于非直肠炎组（ χ2=18.426， P＜0.001）；Fisher确切概率法示2组高位内口发生率差异有统计学意义（P=0.044），肛提肌上瘘管及肛提肌上脓肿发生率差异均无统计学意义（均P>0.05）。结论与未合并直肠炎的肛周克罗恩病比较，合并直肠炎的肛周克罗恩病患者MRI表现具有一定的特异性。
Abstract:
[Abstract]ob＜x＞jective To investigate the MRI features of perianal Crohn’’’’’’’’’’’’’’’’s disease in patients with and without proctitis. Methods 57 patients with perianal Crohn’’’’’’’’’’’’’’’’s disease in Affiliated Hospital of Yangzhou University and Affiliated Hospital of Nanjing University of Chinese Medicine from September 2017 to July 2021 were analyzed retrospectively, including 42 males and 15 females, aged from 21 to 56 years, with an average age of 29 years. 30 cases of perianal Crohn’’’’’’’’’’’’’’’’s patients with rectal inflammation were set as proctitis group, and 27 cases of perianal Crohn’’’’’’’’’’’’’’’’s patients without rectal inflammation were set as non proctitis group. The following indexes were analyzed by MRI images: The thickness of rectal wall; Apparent diffusion coefficient (ADC) of rectal wall; T2 signal of rectal wall; Whether the position of fistula opening is high (the position of fistula opening in rectal wall is regarded as high); Supralevatoric fistula; Supralevatoric abscess. Independent sample t-test (normal distribution) or nonparametric test (skew distribution) was used for comparison between measurement data groups；Count data were described as the percentage, and comparisons between groups were performed by using the chi-square test or Fisher’s exact test.Results The mean rectal wall thickness in proctitis and non proctitis groups were (8.4±2.1)mm and (5.5±1.6)mm respectively, and the mean ADC was 1.09×10-3 mm2/s and 1.36×10-3mm2/s respectively; In proctitis group, there were 7, 14 and 9 cases with obvious-moderate-slight increase of T2 signal in rectal wall, and in nonproctitis group, there were 2, 7 and 20 cases. The incidence of high fistula opening in proctitis group and non proctitis group were 43.3% and 18.5%. The incidence of supralevatoric fistula was 23.3% and 7.4%, and the incidence of supralevatoric abscess was 13.3% and 0%. There were significant differences in rectal wall thickness, ADC value, T2 signal of rectal wall and the incidence of high fistula opening between proctitis group and non rectal group (P<0.05), but there were no significant differences in the incidence of supralevatoric fistula and abscess(P>0.05). Conclusion Compared with perianal Crohn’’’’’’’’’’’’’’’’s disease without proctitis, MRI findings of patients with perianal Crohn’’’’’’’’’’’’’’’’s disease with proctitis have certain characteristics.
