| 目的：探究经直肠超声造影（CEUS）和彩色多普勒超声（CDUS）对直肠癌与直肠间质瘤的鉴别诊断作用。方法：回顾性的分析2017年1月至2020年1月在本院进行治疗的82例直肠肿瘤患者的病历资料，根据术后组织病理学检查结果分为两组，直肠癌组53例，直肠间质瘤组29例。比较两组患者最大直径、血流峰值流速、阻力指数，声像图特征，峰值强度（IMAX）、上升时间（RT）、达峰时间（TTP）、平均渡越时间（mTT），以及鉴别诊断直肠癌与直肠间质瘤的符合率。结果： 直肠癌组平均最大直径、血流峰值流速、阻力指数均明显高于直肠间质瘤组，差异均有统计学意义（P<0.05）。在CDUS特征上，直肠癌较直肠间质瘤内部回声均匀、大多病灶包绕肠腔，比较差异均有统计学意义（P<0.05）。直肠癌组CEUS参数IMAX值高于直肠间质瘤组，CEUS参数RT值、TTP值、mTT值明显低于直肠间质瘤组，差异均有统计学意义（P<0.05）。经直肠CEUS诊断直肠癌的准确率为98.11%（52/53），诊断直肠间质瘤的符合率为93.101%（27/29），总符合率96.34%（79/82），经直肠CDUS诊断直肠癌的符合率为86.79%（46/53），诊断直肠间质瘤的准确率为89.66%（26/29），总符合率87.80%（72/82），经直肠CEUS诊断直肠癌的符合率、鉴别诊断直肠癌与直肠间质瘤的总符合率明显高于CDUS，差异均有统计学意义（P<0.05）。结论：经直肠CEUS和CDUS对直肠癌与直肠间质瘤的鉴别诊断作用较高，且经直肠CEUS较CDUS鉴别诊断价值更高，值得推广使用。 |

| Abstract: |
| Objective: To explore the role of transrectal contrast-enhanced ultrasound and color Doppler ultrasound in the differential diagnosis of rectal cancer and rectal stromal tumor. Methods: A retrospective analysis was made of the medical records of 82 patients with rectal cancer who were treated in our hospital from January 2017 to January 2020. According to the results of postoperative histopathological examination, they were divided into two groups: the rectal cancer group (53 cases) and the rectal stromal tumor group (29 cases). The maximum diameter, peak blood flow velocity, resistance index, ultrasonographic characteristics, IMAX, RT, TTP and MTT of the two groups were compared, and the coincidence rate of differential diagnosis between rectal cancer and rectal stromal tumor was also compared. Results: The mean maximum diameter, peak flow velocity and resistance index of rectal cancer group were significantly higher than those of rectal stromal tumor group (P < 0.05). In CDUS features, the internal echo of rectal cancer was more uniform than that of rectal stromal tumor, and most of the lesions surrounded the intestinal cavity, the difference was statistically significant (P < 0.05). The IMAX value of CEUS in rectal cancer group was higher than that in rectal stromal tumor group, and the RT value, TTP value and MTT value of CEUS were significantly lower than those in rectal stromal tumor group (P < 0.05). The accuracy rate of CEUS was 98.11% (52 / 53), 93.101% (27 / 29), 96.34% (79 / 82), 86.79% (46 / 53), 89.66% (26 / 29) and 87.80% (72 / 82), respectively The total coincidence rate of different diagnosis of rectal cancer and rectal stromal tumor was significantly higher than that of CDUS (P < 0.05). Conclusion:Transrectal CEUS and CDUS play a higher role in the differential diagnosis of rectal cancer and rectal stromal tumor, and transrectal CEUS has a higher value than CDUS, which is worth popularizing. |
