Endosonography-guided cholangiopancreatography [PDF]
Gastrointestinal Endoscopy, 1996 Detailed imaging of the common bile duct and main pancreatic duct is possible with endosonography. Utilizing a custom manufactured flexible needle, we have developed a technique of performing endosonography-guided cholangiopancreatography (EGCP).Of 205 patients undergoing ERCP, complete ductography was not possible in 11 patients.

Fundamentals of Endosonography
Gastrointestinal Endoscopy Clinics of North America, 1992In this article the fundamentals of endosonography are discussed. Because ultrasonography consists of acoustic waves, some basic principles of these mechanical waves and how transducers convert electrical energy to acoustic waves are first considered. The concepts of resolution, penetration, and attenuation are explored. The origin of ultrasound echoes
