子宫肌瘤可不开刀,HIFU超声无创治疗

2017-05-10 许珈 澎湃新闻

体检发现子宫肌瘤,可医生告知肌瘤还不够大,不能做手术,这时候该怎么办?以往,医生都会建议患者随访,等到肌瘤长到五公分以上,符合手术指征后再开刀。可明明知道子宫里有个肌瘤,却还要等待它长大,实在是让人难以安心。要知道,子宫肌瘤是妇科常见疾病,虽属良性肿瘤,但也会产生痛经、月经过多以及压迫膀胱导致小便次数过多等不适,影响正常生活。对付子宫肌瘤只有等它长大了才有办法吗?难道非要等到无法控制了才去挨刀吗?

要知道,子宫肌瘤是妇科常见疾病,虽属良性肿瘤,但也会产生痛经、月经过多以及压迫膀胱导致小便次数过多等不适,影响正常生活。对付子宫肌瘤只有等它长大了才有办法吗?难道非要等到无法控制了才去挨刀吗?

放到以前,可能真的只有等待。但随着科技进步,已经有了一种“隔山打牛”的方法。也就是说,在不用开刀的情况下,通过超声波“烧死”肌瘤。

上海市六人民医院超声科副主任医师姜立新介绍,“高强度聚焦超声”(High Intensity focused ultrasound,缩写为HIFU)治疗系统专门用于无创性治疗子宫肌瘤。它采用聚焦探头将低能量的超声波准确聚焦于靶组织,能量能够放大到数千倍,主要利用超声的热效应使肌瘤组织发生凝固性坏死,阻断肌瘤的血供,使肌瘤组织失去活性并最终被机体吸收,从而达到“原位消融”的目的。

“生肉烧成了熟肉,血供也被切断了,自然就不会再长了,之后患者只要等待肌瘤萎缩吸收掉就好。”姜立新解释,相比腹腔镜手术需要打三个洞,HIFU治疗基本上可以算是无创的。 “利用超声波的可视性、组织穿透性和聚焦性等物理特征准确定位,能达到彻底‘切除’病变组织,又保护周围的正常组织的效果。另一方面,超声波在聚集的途径中,因为能量未能达到一定的阈值,所以也不存在烫伤或损害表皮或其他组织,在这点上大大改善了患者的就医体验。”

据悉, 高强度聚焦超声治疗子宫肌瘤的优势是在于其微创,整个治疗过程对皮肤、皮下组织以及子宫的其他部位没有损伤。因此术后患者恢复很快,一般来说手术当天即可回家。而无创、无辐射污染的治疗模式也更适合有生育需求的女性。

另外,HIFU治疗不仅对子宫肌瘤有效,对于一些恶性肿瘤也有一定的治疗效果。复旦大学附属肿瘤于2003年在国内最早开展了胰腺癌海扶刀治疗,目前已经累计完成了超过1000例病例治疗。数据显示,海扶刀治疗可以明显延长晚期胰腺癌患者生存期。

大家可能知道,胰腺癌到后期那是“痛不欲生”。HIFU治疗虽然并不能治愈胰腺癌,但的确可以减轻患者的疼痛感。对于患者而言,不痛也是很大的安慰。
