ABSTRACT
Objective To investigate the best models of esophageal cancer surgical approaches,lymphadenectomy ranges and postoperative comprehensive treatment.Methods From January 1998 to December 2007 in 10 years,1 162 cases of different parts with esophageal cancer were analysized which were treated with surgically adopting sequential abdomen,chest,neck three-incision approaches.Taking three-step screening way of preoperative imaging,preoperative ultrasound localigation fineneedle aspiration biopsy cytology and intraoperative rapid fieezing pathological examination were applied to make the selectivity of the first-times cervico-thoraco-abdominal three-field lymph node dissection (3FLND),first-times standard thoracoabdominal two-field lymph node dissection (2FLND) and second-times third-field cervical lymphadenectomy.Meanwhile,we implemented actively postoperative comprehensive treatment and observed the overall clinical efficacy and long-term survival.Results In the group of 1 162 cases with esophageal cancer surgery.The operating resection rate was 100 ％,Radical resection of 97.6 ％ (1 134/1 162).Perioperative overall complication rate was 16.4 ％ (191/1 162).Anastigmatic fistula was 0.6 ％ (7/1 162).Five cases dead in 30 days after surgery.The whole group of lymph node metastasis rate was 52.6 ％ (611/1 162),lymph node metastasis degree in 12.1％ (3 092/25 564).Full group of the first-times 3FLND was 348 cases.The positive rate was 94.8 ％ (330/348),Implementing the first-times 2FLND was in 814 cases and the second-times thirdfield cervical lymph node dissection was performed in 89 cases.The postoperative complications of the 3FLND was significantly higher than that of 2FLND (23.6 ％ vs 13.4 ％).The difference was statistically significant (x2 =18.37,P ＜ 0.001).However,The difference was not statistically significant between 3FLND and 2FLND (P ＞ 0.05).There is no significant difference between the first-times 3FLND with the second-times 3FLND accumulating survival (P ＞ 0.05).But different degree of lymph node metastasis determined prognosis.The difference was significant (x2 =35.57,P ＜ 0.001).In our group the postoperative comprehensive treatment application rate was 87.2 ％.Surgery combined with comprehensive treatment overall 1,3,5 years survival rates were 92.1％,69.2 ％,49.6 ％ respectively.Conclusions The sequential three-incision approaches and selectivity of lymph node dissection have the radical nature thoroughly,fewer complications,high quality of life and the long-term survival advantages.It should be a widely used method in the clinical surgery of the esophageal cancer.Implementing the three-step screening way to selecting the first-times 3FLND,the firsttimes 2FLND and the second-times third-field cervical lymphadenectomy that have targeted strongly and high accuracy,a definite object in view and avoiding patient excessive trauma.Applying the comprehensive treatment after surgery and the re-treated of patients with recurrence that can further more improve the longterm survival of patients.The comprehensive treatment should be the target direction of the future development of esophageal cancer.
