Abstract:
Objective To investigate the diagnostic value and the best criteria of multiplanar reconstruction (MPR) of spiral CT in recurrent laryngeal nerve lymph node metastasis. Methods We performed multiplanar reconstruction of the spiral CT data of 138 esophageal carcinoma patients admitted to our hospital between December 2016 and June 2019, including 113 males and 25 females with an average age of 47-85 (63.03±15.58) years. The short and long diameters of recurrent laryngeal nerve lymph nodes were measured respectively, and then ratio of short to long diameter was calculated. The three parameters were contrasted with the pathological results and the receiver operating characteristic (ROC) curves for the parameters were drawn. Results Of the 138 patients, 291 left recurrent laryngeal nerve lymph nodes were dissected with an average number of 0-14 (2.11±0.41) per patient and the metastasis rate was 16.70%; while 436 right ones were dissected with the average number of 0-17 (3.16±0.45) per patient and the metastasis rate was 21.00%. The total metastasis rate was 29.70%. In the diagnosis of lymph node metastasis, the areas under ROC curve for short and long diameters as well as the ratio of short to long diameter of left recurrent laryngeal nerve lymph nodes were 0.808, 0.779, 0.621, respectively, while those for the right ones were 0.865, 0.807, 0.637, respectively. Conclusion The metastasis rate of recurrent laryngeal nerve lymph nodes is high and the short diameter has a higher diagnostic value for recurrent laryngeal nerve lymph node metastasis.
