Current treatment strategies of variceal bleeding (VB) include banding and sclerotherapy. However, up to 10% of bleeding events remain refractory to standard therapy with high mortality. With this study, we aimed to evaluate the implantation of self-expanding metal stents (SEMS) for the management of therapy-refractory variceal bleeding.
Eight cirrhotic patients who presented to our unit with a total of 9 refractory bleeding events were treated by SEMS placement.
Stenting resulted in immediate hemostasis in all cases without recurrent bleeding with SEMS in situ. After stabilization, 1 patient was treated by transjugular intrahepatic portosystemic shunt (TIPS) and after the second bleeding episode by TIPS dilation. One patient underwent orthotopic liver transplantation (OLT). The remaining patients were treated with standard drug regimens to reduce portal pressure. The SEMS were removed after a median of 11 days. No acute hemorrhage was noted on stent retrieval. While no early rebleeding occurred in the patients after TIPS implant, TIPS dilation or OLT, 3 out of 5 patients on conservative treatment experienced recurrence of VB within 9 days after SEMS removal.
SEMS placement sufficiently stops hemorrhage in refractory VB. Due to the high rebleeding rate after conservative treatment alone following SEMS removal, this procedure may be utilized as a mere bridging method. Additional interventional and/or surgical methods to effectively reduce portal pressure (i.e. TIPS, OLT) should be considered. Further studies to evaluate the optimum treatment algorithm of refractory esophageal VB are warranted.
目前,治疗静脉曲张出血(VB)的策略包括套扎和硬化治疗。然而,高达 10%的出血事件对标准治疗仍然具有抗性,死亡率较高。本研究旨在评估自膨式金属支架(SEMS)在治疗难治性静脉曲张出血中的应用。
8 例肝硬化患者共发生 9 次难治性出血事件,我们采用 SEMS 放置术对其进行治疗。
支架置入术即刻止血,所有病例均未出现 SEMS 在位时再次出血。病情稳定后,1 例患者接受了经颈静脉肝内门体分流术(TIPS)治疗,第 2 次出血后行 TIPS 扩张术。1 例患者接受了原位肝移植(OLT)。其余患者采用标准药物方案降低门静脉压力。支架中位放置 11 天后取出。取支架时无急性出血。TIPS 植入、扩张或 OLT 后患者无早期再出血,但在 SEMS 取出后接受保守治疗的 5 例患者中有 3 例在 9 天内再次发生 VB。
SEMS 放置术能充分控制难治性 VB 的出血。由于 SEMS 取出后单纯保守治疗的再出血率较高,因此该方法可作为临时治疗方法。应考虑采用其他介入和/或手术方法以有效降低门静脉压力(如 TIPS、OLT)。需要进一步研究以评估难治性食管 VB 的最佳治疗方案。
