Application of recurrent laryngeal nerve detector in the neck anastomosis of upper or middle-thoracic esophageal carcinoma / 肿瘤研究与临床

ABSTRACT

Objective To evaluate the effect of recurrent laryngeal nerve detector on the operation of upper or middle-thoracic esophageal carcinoma. Methods A total of 60 patients with resectable esophageal carcinoma in Beijing Tsinghua Changgung Hospital from January 2015 to December 2017 were recruited. These patients were randomly divided into experimental group and control group by using random number table method.The experimental group used recurrent laryngeal nerve detector to assist in the nerve exploration and separation. The control group was treated by routine operation method, and the operation effect of the two groups was compared. Results In the experimental group, the time spent on the confirmation of recurrent laryngeal nerve was significantly shorter than that in the control group [right side 1.50 min (1.00, 1.63 min) vs. 5.50 min(4.88, 6.50 min), Z= -6.715, P < 0.05; left side 1.75 min (1.50, 2.00 min) vs. 7.85 min (6.50, 9.00 min), Z= -6.726, P< 0.05]. The rate of recurrent laryngeal nerve injury in the experimental group was significantly lower than that in the control group [3.3 % (1/30) vs. 20.0 % (6/30), χ 2= 4.043, P < 0.05]. Conclusion The use of recurrent laryngeal nerve detector in the neck anastomosis of upper or middle-thoracic esophageal carcinoma can significantly shorten the time spent on confirming of the recurrent laryngeal nerve and reduce the rate of recurrent laryngeal nerve injury.
