JAMA:直肠癌外科手术中转开腹风险比较研究——机器人辅助vs腹腔镜

2017-10-25 zhangfan MedSci原创

研究认为,对于结直肠癌根治性切除患者,接受机器人辅助手术不能显著降低中转开腹发生率,相比于有经验的外科医生,机器人辅助治疗未显示出显著的优势

近年来机器人辅助直肠癌手术的比例不断上升,但对其安全性和有效性的研究尚不充分。近日研究人员比较了直肠癌患者机器人辅助手术和传统腹腔镜手术的中转开腹风险差异。

10个国家,29个中心的471名患者参与研究,其中机器人辅助手术患者237人,腹腔镜手术患者234人,患者接受上(上部直肠)或下(总直肠)前方切除术以及腹会阴联合切除术(直肠和会阴)。研究的主要终点是中转开腹,次要终点包括术中和术后并发症、环切切缘阳性(CRM+)和其他病理结果、生活质量评估、膀胱和性功能障碍以及肿瘤预后。

参与者平均年龄64.9岁,67.9%为男性,98.9%的患者完成研究。总的中转开腹率为10.1%,其中机器人辅助组发生19例(8.1%),腹腔镜组发生28例(12.2%),风险差异为4.1% (95% CI,-1.4%-9.6%; OR =0.61 [95% CI,0.31-1.21])。总的CRM阳性率为5.7%,机器人辅助组12例(5.1%),腹腔镜组发生14例(6.3%),风险差异为1.1% (95% CI,-3.1%-5.4%; OR=0.78 [95% CI, 0.35-1.76])。发生了8起其他次要终点事件,包括术中后并发症、手术计划变更、30天死亡、膀胱和性功能障碍,但各组间差异无统计学意义。

研究认为,对于结直肠癌根治性切除患者,接受机器人辅助手术不能显著降低中转开腹发生率,相比于有经验的外科医生,机器人辅助治疗未显示出显著的优势。
