ABSTRACT
Objective To study the reliability and feasibility of video-assisted thorascopic lymphadenectomy for complete resection of non-small cell lung cancer(NSCLC).Methods From May 2007 to October 2008,31 patients with NSCLC underwent video-assisted thorascopic radical lobectomy combined with systemic lymphadenectomy in our hospital.The patients were divided into video-assisted thorascopic surgery(VATS) group(n=14) and video-assisted mini-thoracotomy(VAMT) group(n=17).The numbers of removed and metastatic lymph nodes were counted.The results and the follow-up outcomes were compared between the two groups.Results No patient dead or showed serious perioperative complications in both the groups.No significant differences were found between the VATS and VAMT groups in the operation time [(193?92) min vs(188?101) min,t=0.143,P=0.887],blood loss [(592?123) ml vs(648?120) ml,t=-1.297,P=0.211],number of removed lymph nodes [(14.6?7.5) vs(15.2?4.5),t=0.262,P=0.795],or 1-year rate of recurrence or metastasis [21.4%(3/14) vs 13.3%(2/15),P=0.651].Conclusion For patients with NSCLC,no significant difference exists between the outcomes of video-assisted thorascopic surgery and video-assisted mini-thoracotomy.
ABSTRACT
Objective To study the effects of intrinsic ganglionated plexi on the susceptibility to atrial fibrillation(AF)in canines induced by rapid atrial pacing.Methods Atrial efficient refractory period(AERP)and the dispersion of AERP were obtained in 13 healthy mongrel dogs before paced at 600 bpm.The fat pads containing the ganglionated plexi located on the junction of right superior pulmonary vein and atrium in 7 dogs were excided(denervation group),while the fat pad in the other 6 dogs were kept(control group).The time for the emerge of sustained AF was recorded.Atrial efficient refractory period(AERP)and the dispersion of AERP were also determined.Results There was statistical difference in the time for the emergence of sustained AF.In denervation group,it took more time than the control group(120?67 h vs 80?52 h,P
