The retrievable puncture anchor traction method for EUS-guided gallbladder drainage: a porcine study

EUS-guided gallbladder drainage (EUS-GBD) is a challenging technique for endoscopists that requires a high level of skill. A very important reason why EUS-GBD is challenging is that the gallbladder can be easily collapsed. In order to resolve this concern, 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 retrievable puncture anchor using a porcine model.
