Experience in diagnosis and treatment of recurrent oral ulceration associated with gastroesophageal reflux disease

Objective To investigate the treatment outcome of lobectomy for non-small cell lung cancer with da Vinci Surgical System. Methods From Jan. 2012 to Jan. 2015, 202 patients with non-small cell lung cancer underwent lobectomy and systematic node dissection. 80 patients underwent robot-assisted thoracic surgery(RATS) (RATS group) and 122 patients underwent video-assisted thoracic surgery(VATS) (VATS group). To compare and analyze the condition of lmphy nodes dissection and outcomes of patients in the two groups. Results There were significant difference between RATS group and VATS group in dissected total number of lmphy node [(16.93 ± 8.00) vs (13.98 ± 8.67)] and team [(4.89 ± 1.57) vs (4.25 ± 1.23)], the 2 years disease free survival rate (71.2% vs 57.4%), the dissected number of lmphy node of stage Ⅰ [(16.59 ± 8.57) vs (11.86 ± 6.61)], the 2 years disease free survival rate (84.3% vs 57.8%) and overall survival rate (96.1% vs 84.4%). There were also significant difference between two groups in blood loss [(57 ± 49)ml vs (211 ± 180)ml ], drainage volume [POD 1(255 ± 116)ml vs (332 ± 175) ml, POD 2(259 ± 114)ml vs (321 ± 172)ml ]. Whereas there were no significant difference between the two groups in other outcomes. Conclusion The RATS dissected more number of lmphy node and took better median outcomes than VATS in NSCLC.
