| 目的 采用CT小肠造影（CTE）探讨克罗恩病回结肠病变与是否伴发肛瘘之间的关系。方法 连续收集在本院确诊为克罗恩病回结肠病变活动期且接受CTE及肛管MRI的患者28例，其中肛瘘组16例、无肛瘘组12例，计算患者回盲部及结直肠病变的数目、最大病变的长度及相邻病变间的最小距离，并通过秩和检验分析2组间是否具有差异。结果 28例患者中，肛瘘组87.50%（14/16）累及左半结肠或直肠，无肛瘘组50.00%（6/12）累及左半结肠或直肠，差异有统计学意义（Z=－2.135，P<0.05）；肛瘘组回结肠克罗恩病的平均病变数目为3.06个，非肛瘘组为2.91个，差异无统计学意义（P>0.05）；肛瘘组最大病变长度为（12.79±8.30）cm，无肛瘘组为（7.04±3.09）cm，差异无统计学意义（P>0.05）；肛瘘组相邻病变间的最小距离为（5.23±2.98）cm，无肛瘘组为（8.44±2.87）cm，差异有统计学意义（Z=－2.095，P<0.05）。结论 克罗恩病是否发生肛瘘与病变位置及相邻病变间的距离有关，而与病变的数目和最大病变长度无关。 |

| Objective To explore the relationship between ileocolonic lesions and perianal fistulas of Crohn's disease assessed by CT enterography (CTE). Methods Totally 28 patients with initial diagnosis of active ileocolonic lesions of Crohn's disease were collected, 16 with perianal fistula and 11 without perianal fistulas. All patients underwent CTE and pelvic MRI. Total number of lesions, minimum length between every two lesions in colon wall and maximum length of colonic lesions were calculated. The rank sum test was performed respectively. Results Lesions of 14 patients (14/16, 87.50%) in perianal fistulas group located in left colon or rectum, while lesions of 6 patients (6/12, 50.00%) in non-perianal fistulas group located in left colon or rectum, the difference was statistically significant (Z=－2.135, P<0.05). The mean number of lesions in patients with perianal fistulas was 3.06, while in patients without perianal fistulas was 2.91, there was no statistical difference (P>0.05). The maximum length of colonic lesions in patients with perianal fistulas was (12.79±8.30)cm, while in patients without perianal fistulas was (7.04±3.09)cm, and there was no statistical difference(P>0.05). The minimum length between every two lesions in patients with perianal fistulas was (5.23±2.98)cm, while in patients without perianal fistulas was (8.44±2.87)cm, the difference was statistically significant (Z=－2.095,P<0.05). Conclusion Crohn's disease complicated with perianal fistulas has relationship with lesion location and smaller length intervals between two lesions in colon wall, and has no relationship with total number of lesions and maximum length of colon lesions. |
