Chest CT findings of recurrent esophageal cancer after transthoracic esophagectomy with esophagogastrostomy

ABSTRACT

Surgical resection of esophageal cance has played a prominent role in both cure and palliation. The radiologic evaluation of postesophagectomy patients is directed at the detection of normal and pathological appearances after surgical resection. Since early detection of recurrent tumor is important in the management of patients who have undergone esophagectomy, we undertook a retrospective study to evaluate the findings of recurrence on CT in postesophagectomy patients. Between January 1988 and July 1991, 26 patients who had undergone transthoracic esophagectomy with esophagogastrostomy for epidermoid carcinoma of the esophagus with following reoccurance were examined by chest CT. The group included 25 male and one female patients were aged 45-71 years(mean, 53). All patients had studies done immediate post operative 7-10 days. The CT were performed with a CT 9800 scanner (GE Medical System, Milwaukee) after administration of oral contrast media and intravenous injection of contrast media. The findings seen on CT were cnfirmed by biopsy in five cases and by clinical, radiological follow-up manifestation in 21 cases. The abnormalities that were demonstrated on follow-up CT were adenopathy-mediastinal node(ten cases) or abdominal node(five cases), local recurrence-previous tumor site (five case), anastomotic siteI(two cases) or thoracases), peicardial effusion(two cases). Our results indicate that serial chest CT play an important role in the evaluation of the patients after transthoracic esophagectomy with esophagogastrotomy.
