摘要
目的:探讨口服碘番酸胆囊造影CT(简称OCCT)对良恶性胆囊隆起性病变的诊断作用。材料与方法:分析38例手术病理证实的胆囊隆起性病变(胆固醇息肉28例,腺瘤样息肉3例,乳头状瘤1例,腔内型胆囊癌5例和腺瘤恶变1例)的OCCT表现。结果:胆固醇息肉表现为胆囊内多发或单发性颗粒状充盈缺损,直径均≤0.5cm;腺瘤样息肉和乳头状腺瘤均呈单发结节,直径为0.55~0.8cm;腺瘤恶变和腔内型胆囊癌均为体积较大的结节,直径≥1.2cm。结论:OCCT是诊断胆囊隆起性病变的有效方法之一;病变大小是鉴别良恶性胆囊隆起性病变的有力依据。
Objective: To evaluate the value of cholecystographic CT (OCCT), by using iopanoic acid administered orally, in differentiating benign lesion from malignant lesion in the gallbladder.Materials and Methods:38 patients with pathologically proved elevated gallbladder lesions were studied. Of 38 patients, 28 had cholesterol polyps, 3 had adenomatoid ployps, 1 had papiloma, 5 had carcinoma of gallbladder and 1 underwent malignant process of adenoma. Their OCCT features were analysed retrospectively.Results:Cholesterol polyps were manifested as multiple or single granular filling defects in the gallbladder, varied from 0.1~0.5cm in diameter. Both adenomatoid polyps and papiloma took the form of singular nodule, measuring 0.55~0.8cm in diameter. By contrast, all malignant lesions were characterized as large nodules (≥1.2cm in diameter).Conclusion: These results suggest that OCCT is an effective approach for diagnosing of elevated lesions in the gallbladder. The lesion size is a helpful criterion in differentiating benign lesions from malignant lesions.
