Retrievable puncture anchor traction method for endoscopic ultrasound-guided gastroenterostomy: A porcine study

A review of endoscopic ultrasound-guided gallbladder drainage and gastroenterostomy: assisted approaches and comparison with alternative techniques

Over the last 40 years, the role of endoscopic ultrasound (EUS) has evolved from being diagnostic to therapeutic. EUS-guided gallbladder drainage (EUS-GBD) and EUS-guided gastroenterostomy (EUS-GE) are emerging techniques in recent years; however, there are limited studies and inconsistent results regarding these techniques. In addition, EUS has become a more common alternative to traditional interventions due to its super minimally invasive nature, but the mobility of both the gallbladder and intestine makes it challenging to introduce stents. An increasing number of researchers are dedicating themselves to solving this problem, leading to the development of various assisted technologies. Consequently, this review focused on the comparison of EUS-GBD and EUS-GE with other alternative approaches and explored the various assisted techniques employed for EUS-GBD and EUS-GE.

Revolution of hands-on model for interventional EUS: How to make a training model

EUS interventions have an increasing role in the treatment for hepatobiliary-pancreatic diseases. However, the procedure itself is not frequently performed, needs expertise, and carries a high risk of complications. With these limitations, the hands-on practice model is very important for the endoscopist in training for EUS intervention. There have been various hands-on models for EUS interventions, ranging from in vivo living pig model to all-synthetic model. Although a living model provides realistic sensation, the preparation is complex and increases concerns for zoonotic issues. All-synthetic models are easier to prepare and store but not realistic and still need the room for improvement. Hybrid ex vivo model is more widely available and provides various training procedures but still needs special preparation for the porcine tissue.

Endoscopic ultrasound guided gastroenterostomy: Technical details updates, clinical outcomes, and adverse events

Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has been transformed from an innovative technique, into a viable alternative to enteral stenting and surgical gastrointestinal anastomosis for patients with gastric outlet obstruction. Even EUS-GE guided ERCP and EUS-guided gastrointestinal anastomosis for the treatment of afferent loop syndrome have been performed, giving patients more less invasive options. However, EUS-GE is still a technically challenging procedure. In order to improve EUS-GE, several techniques have been reported to improve the technical details. With EUS-GE widely performed, more data about EUS-GE’s clinical outcomes have been reported. The aim of the current review is to describe technical details updates, clinical outcomes, and adverse events of EUS-GE.
