Objective:To investigate the feasibility, safety, and short-term effect of minimally invasive McKeown esophagecto-my. Methods: We conducted a retrospective evaluation of 88 patients with esophageal carcinoma who received minimally invasive esophagectomy in our center from October 2013 to April 2014. Among the 88 patients, 46 patients underwent total endoscopy McKe-own esophagectomy (TEME) and 42 patients underwent thoracoscope combined with laparotomy Mckeown esophagectomy (TLME). The clinicopathologic factors, operational factors, and postoperative complications of the two approaches were compared. Results:The two groups were similar in terms of age, sex, American Society of Anesthesiologists grade, tumor location, preoperative staging, and co-morbidity. The TEME approach was associated with a significant decrease in abdominal blood loss and postoperative pain relative to the TEME approach (P<0.05). No significant differences were found between the two groups in terms of histologic type, postoperation TNM staging, abdominal operation time, intensive care unit stay, chest tube duration, postoperative stay, the number of total lymph nodes dissected or the stations of the total lymph nodes dissected, and lymph metastasis rate (P>0.05). The total morbidity and total re-spiratory complications in the TEME group were lower than those in the TLME group (P<0.05). Incidences of pneumonia, arrhythmia, wound infection of minor complications, and pneumonia of major complications were relatively low in the TEME approach. Conclu-sion:Our TEME technique can be safely and effectively performed for cervical anastomosis during esophageal surgeries to achieve fa-vorable early outcomes.

Background and purpose: The incidence rate of elderly esophageal carcinoma patients is increasing year by year. In this study, the clinicopathologic factors, operational factors and postoperative complications were compared between the older and the younger elderly patients with thoracic esophageal squamous cell carcinoma (ESCC), and the influence of different surgical approaches to older elderly patients were analyzed. Methods: A retrospective review of 371 cases of elderly patients with thoracic esophageal squamous cell carcinoma (≥60 years) between Jan. 2006 and Dec. 2008 were performed. The patients were divided into two age groups. The patients over 75 years old named the older elderly group including 53 patients, and the patients between 60-74 years named the younger elderly group including 318 patients, the clinicopathological factors, operational factors, postoperative hospital mortality and average length of stay were compared. Meanwhile, according to different surgical approaches, the comparison of the left chest and right chest approach of operative time, blood loss and postoperative complication rate, and so on and so forth. Results: The older elderly group compared with the younger elderly group had more preoperative complications. Preoperative ASA classiifcation and postoperative complications, length of stay and hospital mortality rates were signiifcantly higher. The older elderly group over the right chest approach had less postoperative complications, especially pulmonary complications, the results were statistically signiifcant.(13.0%vs 40.0%,P<0.05) Conclusion: The patients over 75 years old with thoracic esophageal squamous cell carcinoma have a higher risk during the operation, we can choose relatively simpler operation approach to reduce the incidence of postoperative complications, especially pulmonary complications.

Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P<0.05). The patients with dissected LNs counts of more than 11 for cases with pTl~2 tumor (P<0.05) and more than 16 for cases with pT3 tumor (P<0.05) had better long-term survival outcomes. The post-operative complication rate was 12.1%, which was not significantly correlated with the number of dissected lymph nodes (P>0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.

Objective: To explore the status of lymph node metastasis of middle third thoracic esophageal squamous cell carcinoma and its influence on the prognosis and to seek the reasonable range of lymphade-nectomy. Methods: A total of 129 patients who underwent curative esophagectomy with modern two-field lymphadenectomy of middle third thoracic esophageal squamous cell carcinoma were reviewed. Results: The lymph node metastasis rate was 56.6% and the upper mediastinal lymph node metastasis rate was 43.4%. The lymph node metastasis ratio (positive nodes/total dissected nodes, LMR) was 11.3%. Paraesophageal lymph nodes, lymph nodes near the right recurrent nerve, the left gastric and infracadnal lymph nodes were most commonly involved when the tumor was located in the middle thoracic esophagus. Tumor differentiation, the depth of tumor invasion and the length of tumor were influencing factors for lymph node metastasis. The 5-year survival of N_0, N_1 (LMR≤20%) and N_1 (LMR>20%) patients were 50.4%, 31.0% and 6.8%, respective-ly, with a significant difference among the three groups (P=0.000). Conclusion: LMR was one of the key fac-tors affecting the prognosis, of esophageal cancer. Patients with middle third thoracic esophageal carcinoma should be treated with radical surgery with modern two-field lymphadenectomy.
