BACKGROUND: We investigated the application value of nanocarbon lymphatic tracer in thoracolaparoscopic esophagectomy.
METHODS: A total of 80 patients were enrolled and randomly divided into the experiment group (n=40) and the control group (n=40). Patients in the experiment group was injected with nano carbon suspension before thoracolaparoscopic esophagectomy, while patients in the control group underwent operation. The total lymph node resection was observed after the operation.
RESULTS: Our results showed that the incidence of recurrent laryngeal nerve injury in experiment group was less than that in the control group. The total complication rate in the experiment group was significantly less than that in the control group. The number of blackstained lymph nodes in the experiment group was significantly more than that in the control group. The black stain rate of thoracic lymph nodes was significantly higher than that on abdominal lymph nodes. The lymph node metastatic ratio of thoracic field in the experiment group was significantly higher than that in the control group. The lymph node metastatic ratio of abdominal field in the experiment and the control groups were 3.6 %, and 2.5 %, respectively. The total lymph node metastatic ratio in the experiment group was more than that of the control group.
CONCLUSIONS: We concluded that the application of nano carbon tracer technique made the field of view of thoracolaparoscopic esophagectomy more clear, and the lymph node dissection more thorough.
