This retrospective study was designed to classify choledochal cysts on the basis of the findings of hepatobiliary scintigraphy.
Twenty-one patients with choledochal cysts (15 female, 6 male; mean age, 20 years) proved on the findings of endoscopic retrograde cholangiopancreatography (ERCP) or surgery and histopathologic analysis were included in the study. Two nuclear medicine physicians, blinded with regard to cholangiographic and operative details, were asked to review and to classify the type of choledochal cyst seen on the hepatobiliary scan. Later, scintigraphic results were compared with ERCP and surgical findings for a reference standard.
The findings of hepatobiliary scintigraphy correlated with ERCP and surgical findings in 18 of 21 cases (86%). Scintiscans correctly identified all type 1 cysts (12/12). The sensitivity of scintigraphy in diagnosing type 4 cysts was 66% (6 of 9 cases). It underestimated the intrahepatic extent of disease in type 4a biliary cysts (37%).
This study illustrates the utility of hepatobiliary scintigraphy in diagnosing type 1 and 4 choledochal cysts.
本回顾性研究旨在根据肝胆闪烁显像的结果对胆总管囊肿进行分类。
纳入21例经内镜逆行胰胆管造影（ERCP）或手术及组织病理学分析证实的胆总管囊肿患者（15例女性，6例男性；平均年龄20岁）。两名对胆管造影和手术细节不知情的核医学医师被要求对肝胆扫描中所见胆总管囊肿的类型进行评估和分类。随后，将闪烁显像结果与ERCP及手术结果进行比较，作为参考标准。
21例患者中，18例（86%）的肝胆闪烁显像结果与ERCP及手术结果相符。闪烁扫描正确识别了所有1型囊肿（12/12）。闪烁显像诊断4型囊肿的敏感性为66%（9例中的6例）。它低估了4a型胆管囊肿的肝内病变范围（37%）。
本研究说明了肝胆闪烁显像在诊断1型和4型胆总管囊肿中的作用。
