Endoscopic ultrasonography: a preliminary report. 1985

B S Thatcher, and M V Sivak, and C George

In order to define normal endoscopic ultrasonographic anatomy with particular emphasis on the pancreas, we studied 25 patients using a prototype ultrasound fiberoptic endoscope (model GF-UM1) and endoscopic ultrasound observation unit (model EU-M1) developed by the Olympus Corporation. We obtained a number of good quality scans of various retroperitoneal structures, and in several cases pancreatic texture and even the pancreatic duct could be appreciated. Differentiation of mucosal from intramural diseases of the hollow gut and from diseases of the retroperitoneal organs can be made by means of endoscopic ultrasonography.

UI	MeSH Term	Description	Entries
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010182	Pancreatic Diseases	Pathological processes of the PANCREAS.	Disease, Pancreatic,Diseases, Pancreatic,Pancreatic Disease
D004724	Endoscopy	Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.

D012187	Retroperitoneal Space	An area occupying the most posterior aspect of the ABDOMINAL CAVITY. It is bounded laterally by the borders of the quadratus lumborum muscles and extends from the DIAPHRAGM to the brim of the true PELVIS, where it continues as the pelvic extraperitoneal space.

D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
