ABSTRACT
Objective To discuss the indication, the prevention and treatment of complications of the esophagectomy through left thoracic and neck approach. Methods 2?058 cases of esophageal carcinoma were analyzed retrospectively. Results The success rate of this procedure was 98.40%, and 33 cases died postoperatively, the mortality was 1.60%(33/2?058). Lymph node metastases were presenting 895 cases. The gross rate of lymph node metastasis was 43.49%(895/2?058), the rates of 1ymph nodes metastasis in neck, chest and abdomen were 5.12%(107/2?058), 42.50%(875/2?058) and 21.19%(436/2?058), respective1y. The occurrence rate of residual carcinoma was 1.51%(31/2?058). The complication rate was 15.74%(324/2?058). 1?870 cases were followed-up (90.86%). The overall 3-, 5-year survival rates were 61.22%(895/1?462) and 36.45%(384/1?053), respectively. Conclusion The advantages of this approach were relatively radical resection, 1ow incidence of residual carcinoma, less severe complications.
ABSTRACT
Objective Wether preoperative freezing plus traditional operative resection would improve 5 year survival of patient with esophageal cancer was studied. Methods 50 patients admitted for esophageal cancer were divided equally at random.The treatment group (n=25) received cryotherapy before traditional surgery.The rest,without pretreatment,had surgery as controls.Their 1,3,5 year survival rates were contrasted. Results With pretreatment the 1,3,5 year survival rate reached 92,76,56 percent respectively,while that of the controls attained 80,40,and 28 percent accordingly.Statistically significant difference in survival did exist between groups by the end of 3 and 5 years after the combined therapy, yet no difference was detected within 1 year. Conclusion Preoperative cryotherapy could reduce the possibility of lymphatic metastasis,iatrogenic spread during operation and improve patient’ s immunological functions and life span.
