肛瘘相关黏液腺癌的临床和超声影像特征

目的探讨肛瘘相关黏液腺癌的临床和超声影像特征。 方法收集2014年5月至2020年12月于哈尔滨医科大学附属第一医院经手术病理确诊为肛瘘相关黏液腺癌的患者11例。所有患者术前均接受了经直肠超声、腹股沟淋巴结超声和肠镜检查，分析所有患者的临床和超声影像特征。 结果所有患者的血清癌胚抗原（CEA）均有不同程度的升高，范围4.26~34.8 ng/ml（正常值为0~3.4 ng/ml），平均值为（12.3±8.4）ng/ml。所有患者的超声表现均为沿瘘管生长的海绵样混合回声团块，其中4例出现了腹股沟淋巴结转移。 结论经直肠超声对于肛瘘相关黏液腺癌的诊断具有较好的应用价值，与血清CEA相结合，可能有助于提高诊断准确性。

Clinical and ultrasonographic features of mucinous adenocarcinoma arising from anal fistula

ObjectiveTo investigate the clinical and ultrasonographic features of mucinous adenocarcinoma arising from anal fistula. MethodsFrom May 2014 to December 2020, 11 patients with mucinous adenocarcinoma arising from anal fistula diagnosed by pathology at the First Affiliated Hospital of Harbin Medical University were collected. All patients underwent transrectal ultrasound, inguinal lymph node ultrasound, and enteroscopy before operation, and the clinical and ultrasonic image characteristics of all patients were analyzed. ResultsSerum carcinoembryonic antigen (CEA) levels in all patients increased in varying degrees, ranging from 4.26 to 34.8 ng/ml (normal value: 0 to 3.4 ng/ml), with an average value of (12.3±8.4) ng/ml. The sonographic findings of all patients were sponge-like solid-cystic masses growing along the fistula, of which four cases had inguinal lymph node metastasis. ConclusionTransrectal ultrasound has good value in the diagnosis of mucinous adenocarcinoma arising from anal fistula. Transrectal ultrasound combined with serum CEA may help to improve the diagnostic accuracy.
