普外科的数字一体化手术室里,参观手术的医生每人带着一个墨镜,而且连台上的手术医生、助手、器械护士也全都带着“黑墨镜”,一个比一个酷。这是怎么回事?戴着墨镜还能做手术吗?他们能看清楚手术视野和腹腔镜显示器吗?让人奇怪的是,他们手里的手术器械好像比以前更得心应手了。在医生注视的方向,一面液晶显示屏上播放着一些模糊不清并且重叠的肝脏和胆囊的影像。原来,这是最新的3D腹腔镜手术演示。

新兴的3D腹腔镜手术,是利用偏振光的原理,实时产生立体图像,使术者操作器械时有了立体方位感觉。实际上是利用在患者体内的腹腔镜镜头包含两个距离非常近的小镜头,各自拍下腔内图像,再通过各自的显示设备把两个角度的图像同步放映,使有细微差别的两幅图像同时显示在显示屏上。这时如果用眼睛直接观看,看到的画面是重叠的、模糊不清的。而使用偏振眼镜观看,左眼只能看到左摄像头拍摄的画面,右眼只能看到右摄像头拍摄的画面,这样组合起来就会看到立体影像,显示屏上的影像立刻变得异常清晰而层次分明,会有“身临其境”的感觉。

前一周内,普外科赵景明主任和郭晏同主任已经完成了5例3D腹腔镜手术,包括腹腔镜胆囊切除术2例,腹腔镜胆总管探查二镜联合取石手术2例,腹腔镜下粘连性肠梗阻手术1例。两位腹腔镜微创外科主任介绍说:普通腹腔镜只有二维图像,而在患者体内操作的腹腔镜器械和观察镜是立体关系,眼睛所看到的二维图像和实际的三维关系存在误差,常常会产生手眼不协调的情况。尤其对于复杂的腹腔手术,肝脏,胆道、血管、胃肠、胰腺等结构错综复杂,稍有不慎,就会造成损伤。而3D高清腹腔镜的三维显示系统,克服了传统腹腔镜的缺点,它的优势在于还原了真实视觉中的三维立体手术视野,使解剖清晰、层次分明。而且具有放大作用,相当于医生进入了患者体内,可以在各种脏器之间查找有病变的部位,再进行精确的切除及重建。因此,使用3D腹腔镜可以最大限度地减少脏器和血管、神经的损伤,比常规腹腔镜进一步减少出血和并发症,缩短手术时间。

3D腹腔镜手术技术的变革为普外科的发展提供了可持续发展的平台。北京积水潭医院普外科腔镜微创手术所涉及的疾病包括:肝脏肿瘤、胆囊结石、胆管结石、胰腺肿瘤、脾脏疾病、胃结直肠肿瘤、腹壁疝、甲状腺疾病、急慢性阑尾炎、腹腔粘连、减肥手术、糖尿病外科手术。
