The diagnosis of a cholecystocolic fistula has often presented a dilemma to the practicing physician. Routine imaging modalities to confirm this diagnosis have not proven extremely successful. The presence of a small fistulous tract from the gallbladder to the colon is often difficult to demonstrate radiographically. However, with the advent of the newer hepatobiliary radioisotopic scanning agents, the ability to visualize the intrahepatic and extrahepatic bile ducts as well as the presence of the intestinal activity of the radiotracers has improved considerably. The authors present a case of cholecystocolic fistula that was adequately demonstrated with a Tc-99m-PIPIDA hepatobiliary scan. This article is the first to report demonstration of this type of fistula with hepatobiliary scanning.
胆囊结肠瘘的诊断常常给执业医师带来难题。用于确诊该疾病的常规影像学检查方法并未取得极高的成功率。从胆囊到结肠的小瘘管的存在往往难以通过放射影像学显示出来。然而，随着新型肝胆放射性同位素扫描剂的出现，可视化肝内和肝外胆管以及放射性示踪剂在肠道内活动的能力有了显著提高。作者报告了一例通过锝-99m-吡哆醛-5'-甲基色氨酸二乙三胺五乙酸肝胆扫描充分显示的胆囊结肠瘘病例。本文是首例报道通过肝胆扫描显示此类瘘管的文章。
