Laparoscopic cholecystectomy is one of the most common procedures performed each year and can be associated with various post-operative complications. Imaging is integral to diagnosis and management of patients with suspected cholecystectomy complications, and a thorough understanding of normal and abnormal biliary anatomy, risk factors for biliary injury, and the spectrum of adverse events is crucial for interpretation of imaging studies. Magnetic resonance cholangiography (MRC) enhanced with hepatobiliary contrast agent is useful in delineating biliary anatomy and pathology following cholecystectomy. In this article, we provide a protocol for contrast-enhanced MR imaging of the biliary tree. We also review the classification and imaging manifestations of post-cholecystectomy bile duct injuries in addition to other complications such as bilomas, retained/dropped gallstones, and vascular injuries.
腹腔镜胆囊切除术是每年最常见的手术之一,可能会伴有各种术后并发症。影像学检查对于诊断和处理疑似胆囊切除术后并发症的患者至关重要,全面了解正常和异常胆道解剖结构、胆道损伤的危险因素以及不良事件谱对于解读影像学检查结果至关重要。磁共振胆胰管成像(MRCP)增强肝胆对比剂有助于描绘胆囊切除术后的胆道解剖结构和病变。本文提供了胆道增强磁共振成像的协议,同时还综述了胆囊切除术后胆管损伤的分类和影像学表现,以及其他并发症,如胆汁瘤、残留/脱落的胆囊结石和血管损伤。
