Comparison of two-field dissection and three-field dissection in esophageal chest lymph node dissection

Abstract

Objective To study the application of two-field dissection and three-field dissection in esophageal dissection.Methods From January 2013 to January 2014,100 patients with thoracic esophageal carcinoma in our hospital were randomly divided into two-field group and three-field group,with 50 cases in each group.The patients in two-field group received two-field lymphadenectomy joint with Ivor-Lewis surgery,and the patients in three-field group received three-field lymphadenectomy combined with Akiyama surgery,the clinical effects were compared.Results Two wild group statistics show the total number of lymph node dissection was 950,ranged 8-39 months,the number of metastatic lymph nodes was observed,a total of 86 ; three wild groups in the total number of lymph node dissection was shown by the statistics of 1500,the range of 16-62 months to observe the lymph nodes turn more than the number of 80 ; statistical incidence of lymph node metastasis in two wild group was 48％,three wild was 70 ％,there was significant difference between the two groups (P ＜ 0.05).Plus two wild groups of mediastinal lymph node metastasis of gastric rate of 50％,the three groups was 44％ ; two wild celiac lymph node metastasis group was 4％,6％ for the three wild group,there was no significant difference(P ＞ 0.05).Two wild group under the mediastinal lymph node metastasis was 32 ％,three wild group was 24％,there was significant difference(P ＜0.05).Two wild group of cervical lymph node metastasis can not be assessed,three wild group was 42％.Between groups and mediastinal lymph node metastasis rate of major differences.Two-field lymph node metastases 3.3,the statistical showing three wild group 2.8,are in the range of 1 to 10,there was no significant difference(P ＞0.05).Two-field lymph node dissection group was 17.0,after statistics show three wild group 32,there was significant difference (P ＜0.05).Two wild group of lymph node degrees is 10％,significantly higher than the three wild groups of 6％ in the second transfer roughness wild group was 20％,significantly higher than the 10percent three wild groups were statistically significant (P ＜ 0.05).Conclusions Line two field lymph node dissection when required to be better left recurrent laryngeal nerve lymph node dissection,threefield lymphadenectomy prognosis may be classified as an ideal,turn on the neck and mediastinum can remove multiple lymph nodes,the abdominal lymph nodes,neck dissection and mediastinal lymph nodes,the prognosis of esophageal chest cancer can be significantly improved.
