Comparison Of Short-term Effects Of Robotic Assisted Thoracoscopic Surgery VS Video-assisted Thoracoscopic Surgery Lung Segmentectomy For Different Kinds Of Lung Segmentectomies

Segmentectomy is increasingly used to resect lung nodules.While robotic-assisted thoracic surgery(RATS)and video-assisted thoracic surgery(VATS)are minimally invasive surgical techniques.There were few researches compared the two approachessurgery and video-assisted thoracic surgery(VATS)in lung segmentectomy.Method:Consecutive lung nodules patients underwent segmentectomy by either robotic surgery or VATS from January 2015 to November 2017 were enrolled.Patients were divided into two groups according to the resected segments.Baseline characteristics and short-time outcomes between two groups were compared.Post-operative characteristics including operation time,blood loss,pneumonia,tumor size,lymph nodes harvested,duration of chest tube,pro-longed air leak,atrial fibrillation,post-operative hospital stay were retrospectively studied.RESULTS:215 patients were included in this study:88 patients were treated by typical segmentectomy and,while 127 patients were treated by atypical segmentectomy.The operation time ofof typical segmentectomy are shorter than that of atypical segmentectomy.The number of lymph nodes dissected in robotic surgery approach was more than in VATS.The skin-to-skin operation time of atypical segmentectomy are shorter than that of atypical segmentectomy.Post-operative hospital stay and the last of chest tube was longer in atypical segmentectomy.There were no significant differences between robotic surgery and VATS in terms of duration of chest driange and postoperative hospitalization days in general.Incidence of some postoperative complications such as pro-longed air leak,atrial fibrillation was not significant different between typical segmentectomy and atypical segmentectomy.CONCLUSION:Atypical segmentectomy is more complicated than atypical segmentectomy,may lead to increases in complications and operation time.Robotic surgery was safe and practical for segmentectomy compared to VATS.More lymph nodes could be dissected by VATS without increasing postoperative complications.
