摘要
目的 探讨经腹彩色多普勒超声检测对肠间质瘤和肠癌的鉴别诊断价值.方法 回顾性分析比较经手术病理证实的肠道间质瘤（25例）和肠癌（30例）患者术前彩色多普勒超声诊断资料.结果 92%的肠道间质瘤患者肿瘤发生于小肠,超声表现为内部呈低回声的实质性肿块,部分内部可出现无回声区,边界清,血流信号丰富,不包绕肠腔生长.30例肠癌患者全部为结直肠肿瘤,超声表现为均匀的低回声肿块,边界不清,多探不到丰富的血流信号,包绕肠腔生长呈＂假肾样改变＂;1例患者发现肿块周边有淋巴结肿大.肠间质瘤超声检测显示的内部回声、肿块与肠腔关系、血流信号等表现与结直肠癌比较,差异有统计学意义（P＜0.05）.结论 经腹彩色多普勒超声能够准确地鉴别肠道间质瘤和肠癌.
Objective To investigate the features of tumor appearance on transabdominal color doppler ultrasonography（CDUS） and its diagnostic value in the differential diagnosis between intestinal stromal tumor and intestinal carcinoma.Methods The preoperative features of the tumor mass on CDUS were reviewed retrospectively in 25 patients with intestinal stromal tumor and in 30 with intestinal carcinoma.All the cases were confirmed by surgery and pathological examination.Results Of the 25 cases with intestinal stromal tumor,23 （92%） were found to be located in the small intestine and the majority presented as a hypoechoic solid mass with clear demarcation and rich color flow signals on CDUS,not growing around the intestinal cavity.A heterogeneous echogenic mass with anechoic space was shown in some stromal tumors.The CDUS showed that carcinoma were all in the colon or the rectum,and showed heterogenous echoic solid masses with ill-defined margin,few color flow signals and pseudokidney sign was often observed in intestinal carcinoma because the mass grew around the intestinal cavity.Internal echo pattern,the relation between mass and intestinal cavity,and color doppler flow signal of intestinal stromal tumors were significantly different from those of intestinal carcinomas （all P〈0.05）.There were no statistical differences in lymphatic metastasis （P〉0.05）.Conclusion CDUS is an effective method to differentiate intestinal stromal tumor from carcinoma.
