Core Tip

Core tip: To evaluate the feasibility of retrievable puncture anchor traction (RPAT)-assisted endoscopic ultrasound-guided gastroenterostomy (EUS-GE), six Bama mini pigs underwent the RPAT-assisted EUS-GE procedure. Four weeks later, a standard gastroscope was inserted into the pig’s intestine through a previously created fistula in order to check the status of the stents under anesthesia. The pigs were euthanized after examination. The results showed that the RPAT-assisted EUS-GE method allowed placement of the stents with no complications in all six animals. This study proved that the RPAT method helps reduce mobility of the bowel. Therefore, the RPAT-assisted EUS-GE method is a minimally invasive treatment modality.
