目的探讨血吸虫性阑尾病变的超声声像特征。方法在2012年1月-2015年12月湖州市中心医院经彩超发现的血吸虫性肝病患者中,选择有明确血吸虫病病史及治疗史的患者50例作为血吸虫性肝病组,并选取50例未发现血吸虫性肝病,且来自非血吸虫病流行区、无血吸虫病病史的普通人群作为对照组,对两组行右下腹阑尾超声扫查。采集两组阑尾最大直径、阑尾壁最厚厚度,并观察阑尾壁回声是否均匀等。结果血吸虫性肝病组阑尾腔最小内径为(2.090±0.790)mm,小于对照组;阑尾壁最厚厚度为(1.332±0.313)mm,大于对照组,差异均有统计学意义(t=2.647、-4.526,P均<0.05)。血吸虫性肝病组阑尾壁回声欠均匀、结构欠清晰、不均匀增厚者比例以及阑尾腔内有肠内容物者比例均高于对照组(χ~2=12.000、18.537、24.008、4.244,P均<0.05)。结论血吸虫性阑尾病变在超声下具有明显的声像特征,超声在判断血吸虫病患者阑尾是否遭受累及,及早发现阑尾病变中有很大价值。
Objective To investigate the ultrasonographic features of schistosomiasis appendicitis. Methods Fifty patients with history of schistosomiasis and history of schistosomiasis were enrolled from January 2012 to December 2015 in Huzhou Central Hospital. Fifty patients with history of schistosomiasis and history of treatment were selected as schistosomal liver disease group, and 50 cases were not found Schistosomiasis liver disease, and non-schistosomiasis endemic areas, no history of schistosomiasis as a control group, the right lower quadrant abdominal ultrasound scan. Two groups of maximum diameter of the appendix were collected, the thickness of the appendix wall, and observe the echo of the appendix wall is uniform. Results The minimum diameter of the appendix cavity was (2.090 ± 0.790) mm in schistosomal liver disease group, which was smaller than that in control group. The thickness of the appendix wall was (1.332 ± 0.313) mm, which was significantly larger than that in control group (t = 2.647, 4.526, P <0.05). In schistosomiasis liver disease group, the echo of the appendix wall was not uniform, the structure was not clear, the proportion of non-uniform thickening and the contents of appendix in the intestine were higher than those in the control group (χ ~ 2 = 12.000,18.537,24.008,4.244, P <0.05). Conclusion Schistosomiasis appendicitis has obvious sonographic features under ultrasound. Ultrasound is of great value in determining whether the appendix of schistosomiasis patients are affected and finding appendix lesions early.
