摘要
目的探讨易合并胆囊癌的高危胆囊结石声像图特征,为胆囊结石患者选择预防性胆囊切除提供影像学依据。方法分析37例胆囊癌合并胆囊结石术前超声检查的声像图特点。结果26例(71%)同时合并慢性胆囊炎。29例(78%)为单发结石且结石大小超过1 cm。扫查时27例(73%)结石不移动。胆固醇性和混合性结石共33例(89%)。结论单发、体积较大且移动性差的胆固醇性或混合性结石更倾向于合并胆囊癌,当超声检查发现上述特点,尤其是同时存在慢性胆囊炎时,提示有较强的预防性胆囊切除指征。
Objective To identify the ultrasonographic features of high-risk gallstones for development of gallbladder carcinoma, and offer imaging clues for prophylactic cholecystectomy in patients with gallstones. Methods Retrospective analysis of the preoperative ultrasonographic features was performed in 37 cases of gallstones with gallbladder carcinoma. Results Twenty-six cases （71%） had chronic cholecystitis. Twenty-nine cases（78%） presented solitary stone with a diameter of over lcm. The stones were unmovable in 27 patients （71%） at scanning. With respect to the nature of the stones,cholesterol and mixed stones accounted for 89%. Conclusions Solitary large cholesterol or mixed gallstone with poor mobility is at high risk for development of gallbladder carcinoma, especially in patients with chronic cholecystitis. In gallstones with the aforementioned ultrasonographic features prophylactic cholecystectomy is justified.
