肠道充盈法在回盲部结肠癌超声诊断中的辅助作用

Assistant role of intestinal tract filling in ultrasonic diagnosis of ileocecal colon carcinomas

目的讨论肠道充盈法在回盲部结肠癌超声诊断中的辅助作用。方法回顾性分析19例经手术证实的回盲部结肠癌患者肠道充盈法前后的声像图表现,病灶的大小、形态、内部回声及彩色多普勒血流信号。结果肠道充盈后19例回盲部结肠癌表现为肠壁限局性结节状向腔内突出或弥漫性非均匀性增厚,回声减低、层次分辨不清,黏膜面不光整,部分可见大小不一的溃疡凹陷。其中,肿块型6例,管壁增厚型4例,溃疡型9例。各型病灶均较充盈法前显示更为清晰,肠道充盈前后回盲部结肠癌超声定性诊断率分别为52.6%和78.9%。结论肠道充盈对回盲部结肠癌的超声诊断有重要的辅助作用,可进一步提高其诊断准确性。

Objective To discuss the assistant role of intestinal tract filling in ultrasonic diagnosis of ileocecal colon carcinomas （ICC）. Methods Nineteen patients with surgically and pathologically proved ICC underwent intestinal tract filling （ITF） before ultrasonic diagnosis. Subsequently, the size, shape, inner echo and color Doppler flow signals of ICC lesions were analyzed retrospectively. Results Following ITF, the affected bowel walls appeared as intraluminal-localized or nodular prominence or diffuse and inhomogeneous thickening, decreasing inner echo, ill-defined layer, non-smooth mucosal surface, and more or less ucelatic indentations. According to the shape of ICC lesions, mass type was found in 6 cases, thickened bowel wall type in 4, and ulcer type in 9. Following ITF, varied types of ICC lesions were more clearly visualized by ultrasonography. The qualitative rate of ICC lesions before and after ITF was 52.6% and 78.9%, respectively. Conclusion ITF plays important assistant role in ultrasonic diagnosis of ICC lesions and can further elevate the diagnostic accuracy.
