    摘要 目的 探讨食管癌术后复发的CT表现特点，并分析其原因。方法 经CT诊断为术后复发病例共48例，分析其CT表现特点；查阅病例，了解切除范围，探讨术后复发的原因。结果 吻合口复发28例，在CT片上表现为吻合口区不规则肿块影；胸胃复发20例，在CT片上表现为纵隔内结节或肿块，胸胃腔变窄，胸胃壁不规则增厚，并形成软组织肿块影。结论 CT检查是诊断食管癌术后复发的重要手段之一；尽可能扩大手术切除范围是减少食管癌术后复发的较好办法。

    Abstract Objective To investigate the computed tomography (CT) characteristics and reason of esophageal cancer after operation(RECAO). Methods CT characteristics and clinical data of 48 cases diagnosed as RECAO were retrospectively reviewed. Results There were 28 cases with anastigmatic recurrence, the signs on CT were mass a rounding anastigmatic. There were 20 cases recurrenced on thoracic stomach, presented mass in mediastinum, the wall of thoracic stomach becaming thickness and mass in the thoracic stomach formed. Conclusion CT is one of the important methods in diagnosing RECAO; More extensive resection is probably a better way to reduce RECAO. ......
