Endoscopic ultrasonography of chronic XXXX and pancreatic pseudocysts.

@entity1 @entity32 @entity788 @entity82
Endoscopic ultrasonography has been applied to 30 @entity1 with suspected @entity788 . All were difficult clinical problems which had not been resolved by conventional ultrasonography. CT scanning, and pancreatography. There were 7 technical failures where the instrument could not be advanced through the pylorus. A definite result was produced in 23 @entity1 . In 7 the EUS findings were confirmed by histology obtained at surgery. In 6 a definite diagnosis of mild chronic @entity788 was made. Previously undescribed morphological features such as peri-ductal @entity82 , @entity32 were shown and correlated with the histological appearance. In 10 @entity1 an EUS diagnosis of a normal pancreas has not been challenged after clinical follow up of six months to two years. The high resolution of EUS is capable of showing unique morphological detail in @entity788 .
