Updates on therapeutic endoscopic ultrasound.

PURPOSE OF REVIEW

Multiple endoscopic ultrasound (EUS) guided therapeutic interventions have been developed for the management of benign and malignant pancreaticobiliary and gastrointestinal luminal pathology. Recent high-quality evidence is increasingly validating these interventions and positioning them within evidence-based therapeutic algorithms.

RECENT FINDINGS

Here we review therapeutic EUS-guided interventions including pancreatic fluid collection drainage, gastroenterostomy, biliary drainage, pancreatic duct drainage and gallbladder drainage. The most up-to-date high-quality evidence supporting these interventions is presented including comparative data with other conventional treatment options. Newer emerging interventions such as tumor ablation are also reviewed. Current controversies and future avenues for research are discussed. The key role of EUS-guided interventions in managing pancreaticobiliary pathology in patients with a surgically altered anatomy is highlighted.

SUMMARY

Multiple EUS therapeutic interventions have evolved from experimental or rescue options to now well established first- and second-line interventions over other endoscopic, percutaneous and surgical alternatives with the support of high-quality data. Further research is needed to better optimize patient selection and guide long term postintervention follow-up.
