Advanced Endoscopic Procedures: An Update for Radiologists.

OBJECTIVE. The purposes of this article are to familiarize radiologists with endoscopic techniques currently in use and to improve identification of clinically relevant imaging findings and procedural complications related to common endoscopic interventions. CONCLUSION. The frequency of performance of therapeutic endoscopic ultrasound-guided procedures has risen precipitously in the last decade. These procedures are replacing surgical and percutaneous approaches to a variety of disease entities. Recent advances include endoscopic bariatric procedures, endoscopic myotomies, and endoscopic ultrasound-guided drainage procedures.
