胡冰:水囊扩张结合支架植入用于良性胆管狭窄复发率低

2013-09-18 佚名 健康报

改变以往单纯支架引流为在应用水囊扩张加一次性多根塑料支架植入的方法,这一“分期循进,引漏扩窄,充分扩张,有效支撑”的创新处理模式,使各类良性胆管狭窄患者的狭窄消除率达87.2%,复发率降至12.8%,各项指标均优于国外平均水平。日前在沪召开的第五届东方胆胰内镜论坛上,二军大东方肝胆外科医院内镜科教授胡冰的报告受到国内外同行的瞩目。 良性胆管狭窄是指非肿瘤原因所致的大胆管腔的狭小,胆汁排泄受阻,引

改变以往单纯支架引流为在应用水囊扩张加一次性多根塑料支架植入的方法,这一“分期循进,引漏扩窄,充分扩张,有效支撑”的创新处理模式,使各类良性胆管狭窄患者的狭窄消除率达87.2%,复发率降至12.8%,各项指标均优于国外平均水平。日前在沪召开的第五届东方胆胰内镜论坛上,二军大东方肝胆外科医院内镜科教授胡冰的报告受到国内外同行的瞩目。

良性胆管狭窄是指非肿瘤原因所致的大胆管腔的狭小,胆汁排泄受阻,引起梗阻性黄疸或胆道感染,胆管狭窄长期存在将导致大量胆石生成、胆汁性肝硬化等严重后果。临床上,良性胆管狭窄常常继发于手术损伤、肝移植术、外伤、慢性炎症等。传统的治疗方法是开腹手术治疗,通常需切除狭窄段、胆道整形及施行胆肠短路吻合,手术创伤较大、难度较高,术后并发症约25%,且术后狭窄复发率达10%-40%.

近年来,内镜微创技术越来越多地应用于良性胆管狭窄的治疗,不仅能减轻黄疸和控制胆道感染,还能有效消除或改善胆管狭窄,免除手术的创伤与风险,获得满意的长期疗效。统计显示:从2004年至2010年间已治疗各类良性狭窄133例,每例平均接受了1.5次内镜治疗,均次放置了2.8根支架,平均支撑13.4个月,拔除支架后平均随访42.1个月,最终狭窄消除率达87.2%,复发率12.8%.与国外文献同类报道相比,本组病例平均内镜干预次数最少,狭窄消除率及复发率优于国外平均水平。

胡冰表示,采用可回收的自膨式金属支架治疗良性狭窄,是近年来国际上新兴的方法,具有治疗周期短、干预次数少、狭窄扩张充分等优点,但目前尚缺乏用于良性狭窄的专用支架。该院内镜科与国内有关单位合作,自主研发出国际上首个适合良性狭窄专用的可撤除自膨式金属支架,已应用于临床患者42例,成功取出支架的取出率100%,平均治疗周期8.1个月,总体狭窄消除率94.1%,都高于国外报道水平。这种新型支架具有原创性,治疗操作简便、径向支撑力好、取出容易、治疗周期短、同时保留了奥迪氏括约肌屏障功能等优点,适合于各种肝外胆管良性狭窄的治疗。

此外,东方肝胆外科医院在国际上率先将双极射频消融技术引入良性胆管狭窄的治疗,通过破坏或软化胆管局部的纤维疤痕组织,提高内镜扩张及支架支撑的疗效,为难治性病例开拓了新的治疗途径。
