Endoscopic experience in the management of duodenal varices (DVs) is limited and challenging given the anatomic constraints and limited experience. The endovascular management of DVs is not yet established and the controversy of whether to manage them by decompression with a transjugular intrahepatic portosystemic shunt (TIPS) or by transvenous obliteration is unresolved. In the literature, the 6-12 month rebleeding rate of DVs after TIPS is 21-37% and after transvenous obliteration is 13%. The purpose of the study is to evaluate the clinical outcome of combined TIPS decompression and transvenous obliteration/sclerosis.
This is a retrospective study (case series) of two institutions, evaluating patients who underwent TIPS and/or transvenous obliteration/sclerosis for bleeding DVs (from January 2009 to June 2013). TIPS was performed according to a standard procedure using covered stents. Transvenous obliteration (variceal sclerosis) from the systemic and/or portal venous circulation was performed utilizing 3% sodium tetradecyl sulfate foam. Transvenous obliteration was commonly augmented with coils and/or vascular plugs. Technical (technical success of establishing TIPS and completely obliterating the DVs) and clinical outcomes (rebleeding rate and survival) were evaluated.
Five patients with liver cirrhosis presenting with bleeding DVs were included in the study with all eventually (and coincidentally) receiving TIPS and transvenous obliteration. Two of the five patients underwent concomitant TIPS and transvenous obliteration in the same procedural setting. However, three patients underwent transvenous obliteration due to bleeding despite a patent TIPS that had been previously placed. The average time from TIPS placement to transvenous obliteration was 125 days (range: 3-324 days). After having both procedures, there was no rebleeding in the patients during a mean follow-up period of 22 months (6-50 months). Coils and/or metallic vascular plugs were used to augment the sclerosant obliteration in four of five patients.
The combination of TIPS decompression and foam sclerosant transvenous obliteration appears to be effective in preventing rebleeding in this limited case series and compares favorably with the existing evidence for either approach [TIPS or balloon-occluded retrograde transvenous obliteration (BRTO)] alone.
鉴于解剖结构的限制和经验有限,十二指肠静脉曲张(DVs)的内镜治疗经验有限且具有挑战性。DVs的血管内治疗方法尚未确立,关于是通过经颈静脉肝内门体分流术(TIPS)减压还是经静脉闭塞来治疗DVs的争议尚未解决。在文献中,TIPS术后DVs的6 - 12个月再出血率为21% - 37%,经静脉闭塞术后为13%。本研究的目的是评估TIPS减压联合经静脉闭塞/硬化治疗的临床效果。
这是一项对两个机构进行的回顾性研究(病例系列),评估2009年1月至2013年6月期间因出血性DVs接受TIPS和/或经静脉闭塞/硬化治疗的患者。TIPS采用标准程序使用覆膜支架进行。利用3%的十四烷基硫酸钠泡沫从体循环和/或门静脉循环进行经静脉闭塞(静脉曲张硬化治疗)。经静脉闭塞通常用弹簧圈和/或血管塞加强。评估技术(建立TIPS和完全闭塞DVs的技术成功率)和临床结果(再出血率和生存率)。
5例肝硬化伴出血性DVs患者纳入本研究,所有患者最终(巧合地)均接受了TIPS和经静脉闭塞治疗。5例患者中有2例在同一手术过程中同时接受了TIPS和经静脉闭塞治疗。然而,3例患者尽管先前已放置的TIPS通畅,但仍因出血接受了经静脉闭塞治疗。从TIPS置入到经静脉闭塞的平均时间为125天(范围:3 - 324天)。两种治疗后,患者在平均22个月(6 - 50个月)的随访期内均未再出血。5例患者中有4例使用弹簧圈和/或金属血管塞加强硬化剂闭塞治疗。
在这个有限的病例系列中,TIPS减压联合泡沫硬化剂经静脉闭塞似乎能有效预防再出血,与单独使用现有任何一种方法(TIPS或球囊闭塞逆行经静脉闭塞术(BRTO))的证据相比效果良好。
