经腹超声检查对结直肠癌化疗患者伴转移的诊断价值

Diagnostic Value of Transabdominal Ultrasonography in Patients with Metastatic Colorectal Cancer Undergoing Chemotherapy

目的:分析探讨经腹部超声检查对结直肠癌化疗患者伴转移的诊断价值。方法:选择我院2020年1月至2023年1月收诊的结直肠癌化疗患者60例,经病理证实伴转移有23例,未转移37例。分别使用飞利浦64排CT诊断仪检查与彩色超声诊断仪检查,比较分析CT与经腹部超声检查的确诊率、诊断伴转移情况、灵敏度与特异度。结果:CT共确诊45例,其中未转移确诊率78.38%、转移确诊率69.57%;经腹部超声共确诊57例,其中未转移确诊率94.59%、转移确诊率95.65%;经腹部超声结直肠癌转移与未转移确诊率均高于CT,比较差异有统计学意义(P<0.05)。经腹部超声与CT的肝转移诊断率均为100.00%,比较差异无统计学意义(P>0.05),经腹部超声检查的肺转移率、胰腺转移率、腹膜转移率、淋巴结转移率略高于CT,比较差异无统计学意义(P>0.05)。经腹部超声与CT在伴肝转移灵敏度上比较差异无统计学意义(P>0.05),腹部超声诊断肝转移特异度(82.00%)高于CT检查(68.00%),差异有统计学意义(P<0.05);而在肺转移、胰腺转移、腹膜转移、淋巴结转移上,经腹部超声的灵敏度、特异度高于CT,比较差异有统计学意义(P<0.05)。结论:结直肠癌常见转移部位有肝转移、肺转移、胰腺转移、腹膜转移、淋巴结转移,经腹部超声用于结直肠癌化疗患者伴转移检查中,其确诊率高,灵敏度与特异度好,建议使用。

Objective To analyze the diagnostic value of transabdominal ultrasonography(TAUS)in patients with metastatic colorectal cancer undergoing chemotherapy.MethodsTotal 60 patients with colorectal cancer received chemotherapy in our hospital from January 2020 to January 2023 were selected.Among them,23 patients with metastasis and 37 without metastasis were confirmed by pathology.The diagnostic rate,diagnosis with metastasis,sensitivity and specificity of computed tomography(CT)and TAUS were compared and analyzed by using Philips 64-row CT scanner and color ultrasonic scanner respectively.Results A total of 45 cases were diagnosed by CT,among which the diagnosis rate was 78.38%in the non-metastatic cancer and 69.57%in the metastatic cancer.A total of 57 cases were diagnosed by TAUS,among which the diagnosis rate was 94.59%in the non-metastatic cancer and 95.65%in the metastatic cancer.The diagnosis rate of metastatic and non-metastatic colorectal cancer by TAUS was higher than that by CT,and the difference was statistically significant(P<0.05).Both diagnostic rates of liver metastasis by TAUS and CT were 100.00%,and there was no significant dfference(P>0.05).The diagnostic rates of lung metastasis,pancreatic metastasis,peritoneal metastasis and lymph node metastasis by TAUS were slightly higher than those by CT,with no statistical significance(P>0.05).There was no significant difference between TAUS and CT in the diagnosing sensitivity of liver metastasis(P>0.05).The specificity of liver metastasis diagnosed by TAUS(82.00%)was higher than that by CT(68.00%),and the difference was statistically significant(P<0.05).For diagnosing lung metastasis,pancreatic metastasis,peritoneal metastasis and lymph node metastasis,the sensitivity and specificity of TAUSwere higher than those of CT,and the differences were statistically significant(P<0.05).Conclusion The common metastatic sites of colorectal cancer include liver metastasis,lung metastasis,pancreatic metastasis,peritoneal metastasis and lymph node metastasis.TAUS is recommended for the diagnosis of metastatic colorectal cancer undergoing chemotherapy,with high diagnosis rate,good sensitivity and specificity.
