原发性胆囊癌的影像学诊断

目的　比较超声 ,CT ,PTC和ERCP对原发性胆囊癌的诊断价值。方法　 74例胆囊癌病人术前分别进行了超声 ,CT ,PTC和ERCP检查 ,对这些影像学检查进行回顾性研究分析。结果　超声 ,CT和ERCP对胆囊癌的正确诊断率分别为 80 .3 % ,88.5 5和 2 5 % .7例直径 >3cm的胆囊癌中有 6例CDFI阳性。 4例伴有黄疸的病人行PTC检查的目的主要是为了PTBD减黄。结论　超声是诊断胆囊癌首选的影像学检查方法 ,CDFI在确定胆囊恶性肿瘤时很有帮助。疑似胆囊癌或有转移和进行临床分期时 ,CT较超声更有用。胆囊癌伴有黄疸的病人 ,PTC和ERCP主要以治疗为目的

Imaging study on diagnosis of primary cancer of the gallbladder

Objective Comparative study on imaging examination among ultrasound, CT, PTC and ERCP in diagnosis of primary cancer of the gallbladder. Methods Seventy-four patients with primary cancer of the gallbladder were examined preoperatively by using ultrasound, CT, PTC and ERCP respectively. These tests were compared in diagnosis of gallbladder cancer retrospectively. Results The diagnostic accurate rate of Ultrasound, CT, and ERCP were 80.3%, 88.5% and 25% respectively. Color Doppler flow image(CDFI) used in six among seven cases with tumor >3 cm in diameter was positive. PTC in 4 cases mainly used for therapeutic drainage. Conclusion Ultrasound should be the first-line tool to examine carcinoma of the gallbladder. CDFI is good at identifying malignant tumors of the gallbladder. CT is better than ultrasonography to diagnose in doubt or decide metastatic lesions and clinical staging of primary cancer of the gallbladder. PTC and ERCP are mainly employed for therapeutic purpose in jaundiced patients with gallbladder cancer.
