Abstract:
Objective Study the diagnostic value of CT to assess the transfer of right recurrent nerve nodes(RRNN) on the thoracic esophageal squamous carcinoma,so as to provide reference for thoracic segment esophageal surgery way.Methods A retrospective analysis from January 2011 to February 2014 in the first affiliated hospital of zhengzhou university at the records of 132 cases of thoracic segment esophageal thoracic surgery with preoperative CT image data,recorded each patient's right recurrent nerve nodes in the largest length to diameter and the average CT number,and compared with postoperative pathologic results.Results With the ROC curve analysis,considering transfer when the length of RRNN' s diameter 8.5 mm or more in CT,the area under the curve is 0.911,the sensitivity is 85.7％,specificity is 78.8％.Considering transfer when the RRNN average CT number acuity 32.50 HU,the area under the curve is 0.815,the sensitivity is 85.7％,specificity is 76.9％.Whether RRNN transfer has significant correlation(P ＜ 0.05) with the length of tumor,tumor location and whether lymph node of other station transfer,doesn' t have significant correlation (P ＞ 0.05)with patients'age,sex,tumor differentiation degree and the T stage.Conclusion When the RRNN length to diameter 8.5 mm or RRNN average CT numberr acuity 32.50 HU,right recurrent nerve nodes should be considered lymph node metastasis,and choose chest conclusion laparoscopic radical prostatectomy.The upper thoracic portion esophageal tumor's length is 5 cm or more,or clinical suspected lymph node metastasis of other station is the risk factor for metastasis of RRNN.
