IV. Conclusion

Endoscopic ultrasound (EUS) is now indispensable imaging modality in clinical practice of gastrointestinal and pancreatobiliary diseases. Interventional EUS includes Endoscopic Ultrasound-guided Fine Needle Aspiration (EUS-FNA) and therapeutic EUS. EUS-FNA was first developed in early 1990s to enhance the diagnostic capabilities of EUS by providing additional pathological findings. The clinical utility of EUS-FNA has been widely accepted, and the number of EUS-FNA procedures has been increasing worldwide. Therapeutic EUS for various kinds of diseases has also been investigated in experimental studies and clinical trials, and some of the EUS-guided techniques are now well established. However, the others have not yet been established. Many and various kinds of interventional EUS techniques are expected to become more feasible as less invasive and safer techniques in the near future.
