Abstract:
Background:Mediastinoscopy is an effective method for the treatment of early esophageal cancer with minimal invasiveness and lower risk. Preoperative accurate staging of esophageal cancer is the key for the choice of mediastinoscopic operation as the treatment modality. Aims:To evaluate the value of combination of endoscopic ultrasonography(EUS)with CT for the treatment of esophageal cancer under mediastinoscopy. Methods:Sixty patients with esophageal cancer were enrolled. The TN staging results of esophageal cancer by EUS and CT examination were compared with the results of postoperative TN staging. Patients were divided into mediastinoscopic operation group and conventional operation group, and the operation time,intraoperative bleeding volume,postoperative pleural drainage flow and postoperative hospitalization time of the two groups were compared. Results:The accuracy rates of preoperative EUS examination in assessing T and N stage were 81. 7% and 83. 3% ,respectively;accuracy rates of preoperative CT examination were 60. 0% and 53. 3% , respectively;and accuracy rates of EUS combined with CT were 85. 0% and 86. 7% ,respectively. Compared with conventional operation group,intraoperative bleeding volume[(178. 2 ± 30. 1)mL vs.(232. 0 ± 48. 2)mL,P ﹤ 0. 05], postoperative pleural drainage flow[( 142. 8 ± 22. 5 ) mL vs. ( 256. 0 ± 42. 3 ) mL,P ﹤ 0. 01 ],postoperative hospitalization time[(12. 1 ± 2. 5)days vs. (14. 3 ± 3. 6)days,P ﹤ 0. 05]in mediastinoscopic operation group were significantly decreased,and no significant difference in operation time was found between the two groups[(152. 4 ± 13. 2) minutes vs.(163. 3 ± 25. 5)minutes,P ﹥ 0. 05]. Conclusions:Combination of EUS with CT examination can improve the accuracy of preoperative staging,thus provides an important reference for the choice of treating esophageal cancer by mediastinoscopic operation.
