DDW 2016:胃内镜下肌切开术有望治疗胃轻瘫

2016-06-10 MedSci MedSci原创

胃轻瘫是一种慢性疾病,影响约4%的人口。这可能是糖尿病或外科手术的并发症,但在约三分之一的情况下,它是特发性的。药物治疗常常无效。 G-POEM是仿照治疗贲门失弛缓症的自然孔内镜POEM(经口内镜下肌切开术)。这两种技术的程序原则,如隧道技术,肌切开术(包括幽门肌切开术)是类似的。 对30例接受G-POEM的胃轻瘫患者进行研究,初步结果在2016消化疾病周上由Johns Hopkins 医

胃轻瘫是一种慢性疾病,影响约4%的人口。这可能是糖尿病或外科手术的并发症,但在约三分之一的情况下,它是特发性的。药物治疗常常无效。

G-POEM是仿照治疗贲门失弛缓症的自然孔内镜POEM(经口内镜下肌切开术)。这两种技术的程序原则,如隧道技术,肌切开术(包括幽门肌切开术)是类似的。

对30例接受G-POEM的胃轻瘫患者进行研究,初步结果在2016消化疾病周上由Johns Hopkins 医院的Mouen Khashab博士公布。

30名患者均有内科治疗,包括A型肉毒杆菌毒素注射剂(Botox)和幽门支架置入术无效的症状。恶心呕吐有25例(83%),体重减轻有27例(90%),胃排空障碍有11例(37%)。

两项早期研究中响应率超过85%

30名患者中,G-POEM过程平均持续时间是72h,平均住院时间是3.4天。

在平均随访5.5个月的时间中(范围3-30个月),26名患者(86 %)有临床响应,定义为胃轻瘫症状改善,没有再住院。对G-POEM无响应的患者中,2名有糖尿病,1名为特发起源性胃轻瘫,1名是术后患者。

Khashab博士报告说:“这些响应是持续的,并且没有进一步的住院治疗。”

17名接受重复胃食管显像的患者中,8例(47%)显示胃排空,6例(35%)显示有改善。

他说:“与此同时G-POEM引起大部分患者胃排空正常化。” 

两名患者发生不良事件(6.7%):一名发生气腹,另一名发生消化性溃疡。

“我们有两个小的并发症,但这30例操作由非常有经验的内镜医师执行,”他解释说。“G-POEM在技术上比食管POEM更有挑战性,因为位置较远。”

在这些“惊人结果”的基础上,Khashab博士说:“我们将在南美和亚洲起动一个多中心前瞻性试验,招募约50名患者。这将被明确。”

第二项针对9例通过G-POEM治疗胃轻瘫的患者的研究结果,由 Aix-Marseille 大学Jean-Michel Gonzalez博士提出。 

“内镜幽门肌切开术与G-POEM技术是可行的,重现性好,安全,” Gonzalez博士说。“在生活质量和特殊症状方面,这种方法似乎是有效的,这在我们的研究中经影像学评价证实。”

所有这九名患者均经过至少6个月的常规治疗无效(其中包括2例进行胃电刺激的患者),有严重的症状,在过去6个月内至少住院两次,并干扰了胃排空

平均手术时间为48分钟,无围术期或术后并发症,术后2天患者均可进食,并在5天后出院。

临床疗效非常高,1月后85%的患者有明显改善。有1例糖尿病伴肾功能不全的患者在2个月时复发。

糖尿病胃轻瘫症状指数(CGSI)评分从术前的3.5下降至术后1个月后的0.9(P<0.001)、3个月后的1.1(P<0.001)。恶心、呕吐、腹痛、胃潴留与早饱症状在3个月时也改善明显(P<0.001),但不包括厌食症。

胃排空一半的时间在术后明显减少(133min:222min;P<0.001)。63%的患者报告生活质量改善。

胃排空对照

Gonzalez博士承认,这些患者需要长期的随访,这是一项前瞻性的研究,他的研究小组已经开始了。

Khashab博士说G-POEM不仅仅可用于复发住院的患者,还可用于“伴恶心、呕吐,明显影响其生活质量,甚至未住院的患者。”

Khashab博士指出,虽然一些患者对单纯的内科药物治疗有响应,但是甲氧氯普胺可能引起迟发性运动障碍,“并且是略微有效”,止吐药只提供症状缓解。在试图进行G-POEM之前,内镜医师应熟练地掌握食管POEM,他说。

冈萨雷斯博士提出了一些程序上的提示:“从幽门五点钟位置开始,继续检查你的方向,并在幽门拱停止。”

这些结果来自小的病例系列,但他们在症状反应及胃排空试验方面表现出“有趣积极的结果”,克利夫兰诊所和消化外科研究所的John Vargo博士说。

“我希望G-POEM将帮助这些病重且生活质量差的患者,”Vargo博士说。“看到这些结果很好,我们期待更长时间的随访和更多的研究对象。”
