目的 探讨腹腔镜胆囊切除术 (LC)中意外发现胆囊癌(UGC)患者的核磁 共振成像(MRI)、CT影像学特点。方法 回顾性分析我院14例UGC患者行LC的术前 MRI和CT检查资料，与病理检查结果进行 对比。结果 14例UGC患者术后病理检查 均确诊为胆囊癌，腺癌12例，鳞癌2例， 影像学检查漏诊9例，误诊5例。结论 LC 术前应全面分析胆囊癌高危人群的临床 资料，规范术前影像学检查技术，尽量 避免漏诊或误诊，术中发现UGC应及时进 行根治手术，并积极采取预防切口转移 的措施。

Objective To explore the imaging features of magnetic resonance imaging (MRI) and CT of unexpected gallbladder carcinoma (UGC) in patients with laparoscopic cholecystectomy (LC). Methods The preoperative MRI and CT examination data of 14 UGC patients treated with LC in our hospital were retrospectively analyzed and compared with the pathological examination results. Results The postoperative pathology examination of 14 cases of UGC patients were diagnosed with gallbladder carcinoma, including 12 cases of adenocarcinoma and 2 cases of squamous carcinoma. Imaging examination showed that there were 9 cases of missed diagnoses and 5 cases of misdiagnosis. Conclusion The clinical data of high-risk gallbladder carcinoma patients should be comprehensively analyzed and the preoperative imaging examination techniques should be standardized, and the missed diagnosis or misdiagnosis should be avoid before LC. The intraoperative UGC should be timely given the radical surgery, and the measures are taken actively to prevent incision transfer.
