目的分析超声对原发性胆囊癌的诊断价值以及误漏诊原因,以期不断提高超声对胆囊癌诊断的准确率。方法整合分析我院2011年10月～2012年10月收治的30例经手术与病理证实为胆囊癌患者的超声资料,结合术前原发性胆囊癌超声表现以及术后病理诊断进行分析。结果本组30例原发性胆囊癌患者中,术前诊断与术后病理证实符合26例,诊断准确率为:86.7%;漏误诊4例,误诊率为:13.3%。胆囊癌超声声像图表现类型分为3种:①12例囊壁局部或弥漫性增厚型,占40%;②8例肿块型,占26.7%;③9例乳头结节型,占30%。结论超声检查对原发性胆囊癌诊断的准确率较高,具有良好的诊断价值,值得推广与应用。但由于其超声表现的多样性,检查时应多体位和多切面的进行观察,避免误诊漏诊发生。
Objective To analyze the diagnostic value of ultrasonic diagnosis of primary gallbladder cancer and the causes of misdiagnosis in order to continuously improve the diagnostic accuracy of ultrasound for gallbladder cancer. Methods The ultrasound data of 30 patients with gallbladder carcinoma confirmed by operation and pathology from October 2011 to October 2012 in our hospital were analyzed. The ultrasonographic findings of preoperative gallbladder carcinoma and the pathological diagnosis were analyzed. Results Among the 30 patients with primary gallbladder carcinoma, preoperative diagnosis and postoperative pathology were consistent with 26 cases. The diagnostic accuracy rate was 86.7%. Misdiagnosis was performed in 4 cases with a misdiagnosis rate of 13.3%. Gallbladder ultrasound sonographic manifestations of the types are divided into three types: ① 12 cases of local wall or diffuse thickening of the wall, accounting for 40%; ② 8 cases of mass type, accounting for 26.7%; ③ 9 cases of papillary nodules, 30%. Conclusion Ultrasonography has a high accuracy in the diagnosis of primary gallbladder cancer and has a good diagnostic value, which is worthy of promotion and application. However, due to the diversity of its ultrasound performance, the examination should be more body and multi-section observation, to avoid misdiagnosis and missed diagnosis.
