经腹超声检查对结肠癌根治术后复发转移的诊断价值分析

Value Analysis of Transabdominal Ultrasonography in the Diagnosis of Recurrence and Metastasis after Radical Resection of Colon Cancer

为探讨经腹超声检查对结肠癌根治术后复发转移的诊断价值,将64例行结肠癌根治术患者作为本次研究对象,均经腹超声检查对复发转移患者的临床资料进行分析,将腹超声检查结果与CT结果进行比较,分析临床诊断价值。结果显示,肝转移瘤呈现类圆形与圆形,周围声晕较宽,表现为“牛眼”征象最多;覆膜转移图像:腹膜表面不平,脏器表面有大网膜,可伴有腹水;结肠癌胰腺转移少,不均匀低回声,有淋巴结肿大声像;吻合口复发表现为“靶环”征象,内部以低回声为主;肠系膜与腹膜后淋巴结转移超声结果显示,周围肠系膜与淋巴结肿大;转移性淋巴结表现为圆形或是椭圆形,以低回声为主;淋巴结门可见偏移、消失,呈“树枝状”改变。经腹超声检查肝转移28.13%、胰腺转移17.19%、腹膜转移21.88%、肠系膜淋巴结转移28.13%、腹膜后淋巴结转移23.43%、吻合口复发10.94%,CT检查肝转移28.13%、胰腺转移6.25%、腹膜转移10.94%、肠系膜淋巴结转移26.56%、腹膜后淋巴结转移21.88%、吻合口复发1.56%;CT检查多发转移率40.63%,单发转移率59.37%,经腹超声检查多发转移34.38%,单发转移65.62%,差异无统计学意义(P>0.05);经腹超声检查吻合口复发灵敏度高于CT检查(P<0.05)。结果表明,经腹超声检查对结肠癌根治术后复发转移的诊断有重要临床意义,与CT比较,经腹超声检查方法的诊断率高,可减少漏诊,值得临床应用。

In order to explore the diagnostic value of transabdominal ultrasonography for recurrence and metastasis after radical resection of colon cancer,64patients undergoing radical resection of colon cancer were taken as the research object.The clinical data of the patients with recurrence and metastasis were analyzed by transabdominal ultrasonography.The results of transabdominal ultrasonography were compared with CT results to analyze the clinical diagnostic value.As results,liver metastases were quasi round and round,with wider surrounding sound halo,with the most"bovine eye"signs;The image of tectorium transfer:the surface of peritoneum is uneven,and there is greater omentum on the surface of organs,which could be accompanied by ascites;Colon cancer had less pancreatic metastasis,uneven low echo and enlarged lymph nodes;The recurrence of anastomotic stoma showed the sign of"target ring",and the interior was mainly hypoechoic;The ultrasonic results of mesenteric and retroperitoneal lymph node metastasis showed that the surrounding mesenteric and lymph nodes were enlarged;Metastatic lymph nodes were round or oval,mainly hypoechoic;Lymph node hilar could be seen to shift and disappear,showing"dendritic"changes.Transabdominal ultrasonography showed liver metastasis of 28.13%,pancreatic metastasis of 17.19%,peritoneal metastasis of 21.88%,mesenteric lymph node metastasis of 28.13%,retroperitoneal lymph node metastasis of 23.43%,anastomotic recurrence of 10.94%,CT liver metastasis of 28.13%,pancreatic metastasis of 6.25%,peritoneal metastasis of 10.94%,mesenteric lymph node metastasis of 26.56%,retroperitoneal lymph node metastasis of 21.88%,anastomotic recurrence of 1.56%;The multiple metastasis rate of CT was of 40.63%,the single metastasis rate was of 59.37%,the multiple metastasis rate of transabdominal ultrasound was of 34.38%,and the single metastasis rate was of 65.62%,which there all was no statistically significant difference(P>0.05);The sensitivity of abdominal ultrasonography to anastomotic recurrence was higher than that of CT(P<0.05).The results show that transabdominal ultrasonography has important clinical significance in detecting recurrence and metastasis after radical resection of colon cancer.Compared with CT,transabdominal ultrasonography has a high diagnostic rate and can reduce missed diagnosis,which is worthy of clinical application.
