Abstract:
Objective To clarify the helical CT features and anatomic distribution of recurrence and metastasis of postoperative esophageal cancer.Methods Fifty patients ( 43 men , 7 women , ages 42~76 , mean 58 years ) with postoperative esophageal cancer underwent helical CT examination.On the basis of axial CT imaging , CT features were evaluated , including types , anatomic distribution and time of recurrence in patients with postoperative esophageal cancer .Results Among 50 patients , 31 patients developed recurrence and metastasis. Of 31 patients , 12 patients had recurrence of upper gastrointestinal tract , including esophagogastric anastomoses (n = 8), esophageal stump (n =1) , and intrathoracic stomach (n=3). Lymph node metastasis were investigated in 28 cases , which included right upper paratracheal (2R, n=11), and subcarinal right(7+8, n=11) ; 13 patients possessed lymph node metastasis of two and over-two regions ; Five patients had abdominal para-aortic lymph node metastasis. Metastasis of lung, liver and pancreas were discovered in 8, 7 and 1, respectively. There were six with pleural fluid . All of recurrence and metastasis occurred in the periods from 3 months to 1 year after surgery (P
