背景和目的：EUS引导胆囊引流（EUS-GBD）对内镜医师来说是一项具有挑战性的技术，需要高水平的技能。EUS-GBD具有挑战性，因为胆囊很容易塌陷。为了解决这一问题，我们旨在开发一种用于EUS-GBD的可回收穿刺锚牵引（RPAT）方法。我们评估和比较了成功率，安全性和结果的RPAT方法EUS-GBD与EUS-GBD没有RPAT使用猪model.Methods：在总数为16巴马小型猪（体重15-20公斤）随机分为实验组（n = 8）和对照组（n = 8）。实验组采用RPAT法，对照组采用不带可回收穿刺锚的EUS-GBD法。结果：实验组8只动物均成功完成EUS-GBD手术（100%），实验组8只动物均成功完成EUS-GBD手术（100%），实验组8只动物均成功完成EUS-GBD手术（100%）。而对照组中仅4头（50%）成功进行EUS-GBD，其余4头因胆囊塌陷导致EUS-GBD失败而死亡。结论：RPAT有助于提高EUS-GBD的成功率，减少胆囊塌陷。因此，我们相信这种方法可以在不久的将来应用于EUS-GBD。此外，RPAT将提高EUS-GBD的安全性。
Background and Aims: EUS-guided gallbladder drainage (EUS-GBD) is a challenging technique for endoscopists that requires a high level of skill. EUS-GBD is challenging because the gallbladder can be easily collapsed. To resolve this issue, we aimed to develop a retrievable puncture anchor traction (RPAT) method for EUS-GBD. We evaluated and compared the success rate, safety, and outcomes of the RPAT method for EUS-GBD against EUS-GBD without RPAT using a porcine model.Methods: In total, 16 Bama mini pigs (weighing 15-20 kg) were randomly divided into an experimental group (n = 8) and a control group (n = 8). The RPAT method was performed in the experimental group and EUS-GBD without retrievable puncture anchor was performed in the control group. Incidence of operative adverse events, wound healing, and success rates of EUS-GBD were compared and analyzed between the experimental group and the control group.Results: All EUS-GBD procedures were successfully performed in all 8 animals in the experimental group (100%). However, in the control group, EUS-GBD was successfully performed only on 4 pigs (50%); the remaining 4 pigs died because of EUS-GBD failure caused by gallbladder collapse leading to unsuccessful frontal stent release.Conclusions: RPAT helped increase the success rate of EUS-GBD and could reduce gallbladder collapse. Therefore, we believe this method can be applied to EUS-GBD in the near future. Furthermore, RPAT will enhance the safety of EUS-GBD.
