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 investigate the diagnostic value of oral iodine acid cholecystography CT (OCCT) in the diagnosis of benign and malignant gallbladder elevated lesions. Materials and Methods: OCCT was analyzed in 38 cases of gallbladder bulging lesions (28 cases of polypus, 3 cases of adenomatous polyps, 1 case of papilloma, 5 cases of endocervical gallbladder carcinoma and 1 case of malignant adenoma) which performed. Results: Cholesterol polyps showed multiple gallbladder or solitary granular filling defects, both diameter ≤ 0.5cm; adenomatous polyps and papillary adenomas were single nodules, the diameter of 0.55 ~ 0.8cm ; Adenoma malignant and endovascular gallbladder cancer are larger nodules, diameter ≥ 1.2cm. Conclusion: OCCT is one of the effective methods for the diagnosis of gallbladder bump lesions. The size of the lesion is a good basis for differentiating benign from malignant gallbladder elevated lesions.
