RESUMEN
Objective To explore and analyze the prognosis of three-field lymph node dissection and two-field lymph node dissection for upper thoracic esophageal carcinoma. Methods 120 patients with esophageal carcinoma who were accepted by our hospital from October 2010 to October 2011 were selected as the research subject. They were randomly and equally divided into the three-field lymph node dissec-tion group and the two-field lymph node dissection group. Contrast the rate of lymph nodes metastasis, rate of surgical survival and complica-tions of two groups after treatment. Results After the operation treatment, cervical lymph node and mediastinal lymph node metastasis rates in were 18. 33% and 20. 00% respectively, and the total incidence of complications is 30. 00%. They were all lower than two-field lymph node dissection group. Meanwhile, the survival rate of three-field lymph node dissection group was 83. 33% which was obviously higher than 58. 33% in the two-field lymph node dissection group with a statistical significance (P<0. 05). Conclusion Three-field lymph node dis-section can effectively improve the prognosis and clinical curative effect in treatment of upper thoracic esophageal carcinoma.
RESUMEN
Objective: To explore the security and the radical and clinical value of thoracoscopic-laparoscopic esophagectomy with two-field lymph node dissection for middle esophageal cancer through comparison with open esophagectomy. Methods: A total of 410 stage II to stage III esophageal cancer patients who underwent two-field lymph node dissection with two different methods (thora-colaparoscopic esophagectomy and open esophagectomy) from January 2009 to July 2013 in Uninon Hospital, Fujian Medical Universi-ty, were analyzed retrospectively. General pathological parameters, operative procedures, and short-term outcomes were collected and compared between the two groups (TLG and OG). Results: No significant differences were found regarding general pathological pa-rameters, such as gender, age, etc. Significant differences between thoracolaparoscopic and open two-field lymph node dissection esoph-agectomy were observed in terms of esophagectomy intraoperative blood loss [(206 ± 138) mL vs. (240±111) mL] and the mean num-ber of dissected lymph node per person [(26.6±8.6)/per vs. (21.7±9.2)/per]. Overall postoperative morbidity rate in OG was 35.2%, and its difference from that of TEG (25.8%) is statistically significant (P<0.05). Regarding single complications, such as pulmonary infec-tion and arrhythmia, OG showed evidently superior results (P<0.05). Meanwhile, anastomotic stricture and hoarseness rate are higher in TEG (P<0.05), and the difference was statistically significant as well. Conclusion: Thoracolaparoscopic two-field esophagectomy is technically feasible and safe and can achieve radical tumor resection.
