食管癌术后CT检查的临床价值及其表现

Clinical Potentials and Signs of Post-operative CT in Esophageal Carcinoma

目的:探讨食管癌术后的CT表现及临床价值。方法:回顾性分析40例食管癌术后患者的临床资料及CT表现。结果:40例中肿瘤复发或转移的有33例,占82.5%。胃位于左侧胸腔26例,右侧胸腔12例,后纵隔2例。食管胃吻合口肿瘤复发15例;淋巴结转移26例,共有31个淋巴结;肺转移8例;胸椎和肝转移各4例。结论:食管癌术后CT复查是十分必要的;胸内胃是食管癌术后特有的CT表现;肿瘤复发表现为食管胃吻合口壁增厚;远处转移主要为纵隔淋巴结转移,多发生于气管旁及隆突下。

Objective：To study the clinical potentials and signs of post-operative CT in esophageal carcinoma patients. Methods： The clinical materials and CT manifestations of 40 post-operative cases of esophageal carcinoma were analyzed retrospectively. Results：Relapsing tumors or tumor metastases were found in 33 （82.5%） of the 40 post-operative cases. The pot-operative stomach located within left mediastinum in 26 cases, within right mediastinum in 12 cases,within posterior mediastinum in 2 cases. Relapsing tumors were shown at the site of esophago-gastric anastomosis in 15 cases. Metastatic lymph nodes were demonstrated in 26 cases with a total number of 31 involved nodes detected. Lung metastases were noted in 8 cases. Thoracic vertebrae and the liver metastases were respectively seen in 4 cases. Conclusion：Post-operative CT for esophageal carcinoma patients after operation was very much requisite. Intrathoracic stomach was only a special sign in postoperative cases of esophageal carcinoma. Wail-thickening at the site of esophago-gastric anastomosis indicated tumor recurrence. Mediastinal lymph nodes,particularly the ones locating paratracheally and subcarinally,were frequently the victims of remote tumor metastasis.
