摘　　要：目的 探讨肠充盈超声检查在直肠疾病中的诊断价值。方法 对70例经病理证实的直肠疾病患者行经直肠超声和肠充盈超声检查,观察病灶形态、大小、回声、血流信号、侵犯肠壁程度、直肠周围肿大淋巴结数目及与周围脏器关系等。比较经直肠超声和肠充盈超声检查对直肠疾病的诊断价值。结果 70例患者检出78个病灶,包括48个直肠癌,17个腺瘤和10个炎性团块。经直肠超声检出病灶54个(72%),肠充盈超声检查检出病灶75个(100%),两种方法检出率比较差异有统计学的意义(χ2=22.148,P<0.001)。经直肠超声和肠充盈超声检查对检出病灶定位准确率均为100%。结论 肠充盈超声检查在直肠病灶的病变检出率优于经直肠超声检查,可以无创、实时动态鉴别诊断直肠疾病。Objective To investigate the value of intraluminal contrast-enhanced ultrasonography in the diagnosis of rectal lesions. Methods Intraluminal contrast-enhanced uhrasonography and transrectal ultrasonography were performed in 70 patients with rectal lesions confirmed by pathology. The morphological features and locations of the lesions were observed. The different diagnostic value between transrectal uhrasonography and intraluminal contrast-enhanced ultrasonography was compared. Results Seventy-eight rectal lesions in 70 patients were detected, including 48 rectal carcinomas, 17 adenomas and 10 inflammatry mass. Fifty-four lesions were detected by transrectal ultrasonography, and 75 lesions were detected by intratuminal contrast-enhanced ultrasonography. There was a significant difference between the two methods （χ^2=22.148 ,P〈0.001 ）. All tumor locations were correctly diagnosed by the two uhrasonography. Conclusion The detection rate of intraluminal contrast-enhanced ultrasonography in rectal lesions is better than that of transrectal ultrasonography, which can noninvasively and real-time diagnose rectal lesions.
