摘要
目的比较肠充盈超声检查法与常规经腹超声检查法在结直肠肿瘤中的诊断价值。方法对2008年6月-2009年6月64例经临床病理确诊的结直肠肿瘤患者分别经腹常规超声及肠充盈超声检查。在肠充盈状态下观察病变的形态,对病变进行定位并观察结直肠肿瘤的彩色多普勒血流信号。比较肠充盈超声检查法及常规经腹超声检查法在结直肠肿瘤的检出、定位和显示血流的能力的差异。结果常规经腹部超声检查发现32例结直肠肿瘤(32/64),病灶敏感性为50%;肠充盈超声检查法发现病灶55例(55/64),病灶敏感性为85.9%。经腹常规超声检查的定位准确率为21.9%(7/32),肠充盈超声检查法对结直肠肿瘤的定位准确率为89.1%(49/55)。两种方法比较差异有统计学的意义(P<0.05)。结论肠充盈超声检查法在结直肠肿瘤的病变敏感性检出、定位准确性等方面优于经腹常规超声检查;而不同病理类型的结直肠肿瘤具有不同的超声声像图特征。
Objective To compare the diagnostic value between intraluminal contrast-enhanced hydrocolon ultrasonography and conventional transabdominal ultrasonography for of colorectal neoplasms.Methods The conventional transabdominal ultrasonography and hydrocolonic ultrasonography using an intraluminal contrast agent were performed on 62patients from June 2008to June 2009.The morphological features and location of the lesion were observed and the blood flow signals were observed.The different diagnostic value between conventional transabdominal ultrasonography and intraluminal contrast-enhanced hydrocolon ultrasonography was compared. Results The sensitivity of the intraluminal contrast-enhanced hydrocolon ultrasonography in the depiction of the colorectal neoplasms（55/64,85.9%）was higher than that of the conventional transabdominal ultrasonography （32/64,50%,P0.05）.And the accuracy of the intraluminal contrast-enhanced hydrocolon ultrasonography in locating the colorectal neoplasms （48/55,87.3%）was higher than that of the conventional transabdominal ultrasonography（7/32,53.2%,P0.05）.Conclusion Intraluminal contrast-enhanced hydrocolon ultrasonography is more valuable for colorectal neoplasms than conventional transabdominal ultrasonography in detecting and locating colorectal neoplasms.Colorectal neoplasms with different pathological types may have different ultrasonic features.
