EUS-Guided Transluminal Interventions

Abstract

The role of endoscopic ultrasound (EUS) has transitioned from a diagnostic to a therapeutic one over the past 40 years. With the advent of curvilinear array echoendoscopes in the 1990s with an accessory channel, multiple tools and devices have been developed and used for a variety of transluminal interventions. EUS provides a viable option and is becoming the procedure of choice for many interventions, including bile and pancreatic duct drainage, guiding angiotherapy, pancreatic fluid collection management, gallbladder drainage, and creating a gastrojejunostomy. Although reports demonstrate the technical success of these interventions, there is tremendous study heterogeneity and a relative lack of controlled randomized trials, which may limit our understanding of their role and utility. Furthermore, adverse events are relatively common and occasionally severe. Despite the limitations, available data strongly indicate the efficacy of EUS interventions when performed by well-trained endosonographers in carefully selected patients and managed in a multidisciplinary setting.
