目的 探讨肝脏局灶性增生结节(FNH)的诊断和治疗。 方法 回顾性分析哈尔滨医科大学第一临床医学院1993年1月至2004年12月12年间收治并经病理检查证实的9例FNH的临床、影像学和病理学资料。结果 FNH术前正确诊断率较低，该病多见于中、青年，多无乙型肝炎病毒感染，AFP检查正常，彩色多普勒检查多发现病灶有血管通过，CT动态扫描增强后早期有显著强化，MRI检查也有明显强化。结论 FNH在临床和影像学上均有一定特征，综合分析临床表现、实验室检查与多种影像学资料可提高正确诊断率。
ObjectiveTo summarize the surgical learning curve and evaluate the effectiveness, safety and feasibility of the robotic-assisted thoracoscopic surgery (RATS) by comparing with the conventional vedio-assisted thoracoscopic surgery (VATS).MethodsThe clinical data of 40 patients receiving robotic assisted thoracoscopic anatomic lung resection from March to June 2016 in our department were reviewed. There were 29 males and 11 females with the age of 54-78 (60.2±12.7) years in the RATS group, and 27 males and 10 females with the age of 52-76 (58.7±11.5) years in the VATS group. Lung space-occupying lesions were comfirmed by preoperative diagnosis. The operative time, blood loss, chest tube retention time, postoperative hospital stay and perioperative morbidity and mortality were analyzed. The safety and feasibility were evaluated, and the learning curve was summed up.ResultsOperative time, postoperative ventilation time, intraoperative blood loss, chest tube retention time, postoperative pain, average hospital stay, postoperative complication rate between two groups were not statistically significant. In the RATS group preoperative preparation time was longer than that of the VATS group (24.5 min vs. 15.6 min, P=0.003), and the rate of conversion to thoracotomy of the RATS group was lower than that of the VATS group (0 vs. 10.8%). There was no perioperative death in two groups.ConclusionRobotic-assisted thoracic surgery is safe and effective in the early learning process, and the learning curve can be entered into the standard stage from the learning stage after initial 10 operations.
