目的 :探讨原发性胆囊癌的声像图特点 ,评价超声诊断价值。方法 :回顾性总结了 5 9例经手术病理证实的原发性胆囊癌 ,分析其超声图像特点和误诊原因。结果 :根据超声图像胆囊癌可分为五型 :实块型 2 3例、蕈块型 9例、息肉型 7例 ,厚壁型 9例、混合型 11例。术前确诊 4 7例 ,误诊 12例。误诊为慢性胆囊炎 3例 ,慢性胆囊炎伴结石 5例 ,胆囊息肉 1例 ,肝癌 2例 ,胆总管癌 1例。彩色多普勒可在病灶或周边探及异常血流信号。结论 :超声观察胆囊形态大小、囊壁改变、实质性肿块及其它特征对原发性胆囊癌诊断有重要价值 ,但误诊率仍较高 ,需提高警惕 ,仔细探查
Objective: To investigate the features of sonography of primary gallbladder carcinoma and evaluate the value of ultrasonic diagnosis. Methods: A total of 59 primary gallbladder carcinomas confirmed by surgery and pathology were retrospectively reviewed. The characteristics of ultrasound images and the causes of misdiagnosis were analyzed. Results: According to the ultrasound images of gallbladder cancer can be divided into five types: real type 23 cases, 9 cases of mushroom block, polyp in 7 cases, thick wall in 9 cases, mixed 11 cases. 47 cases were diagnosed preoperatively and 12 cases were misdiagnosed. Misdiagnosed as chronic cholecystitis in 3 cases, chronic cholecystitis with stones in 5 cases, 1 case of gallbladder polyps, liver cancer in 2 cases, 1 case of common bile duct cancer. Color Doppler in the lesions or peripheral exploration and abnormal blood flow signal. CONCLUSIONS: Ultrasonography is of great value in the diagnosis of primary gallbladder cancer because of its size, wall changes, substantial lumps and other features, but its misdiagnosis rate is still high. It should be vigilant and carefully examined
