Abstract:
Objective To investigate the value of endoscopic ultrasonography ( EUS) in diagnosing pancreatic pseudocyst. Methods EUS was performed in 35 cases with pancreatic pseudocyst. Results Of the series, 41 cysts found in the head, body, tail and both body and tail of the pancreas were 13 , 3 , 19 and 6 respectively. The cystic wall was smooth in 29 cysts and rough in 6; good signal in cystic fluid 19, floccu-lar echo 16, cystic septum 1 and calcification of cyst wall 1, associated ductus pancreaticus expansion in 7, pancreas parenchyma uneven echo in 21, pancreas parenchyma calcification in 4, pancreas atrophy in 2, pancreas carcinoma in 2 , and normal pancreas in 6, protuberances impression on gastrointestinal tract 5 ( duodenal descending part obstruction, n = 1 ) stomach varicose vein in fundus 4 and digestive tract hemorrhage 2. Conclusion EUS may clearly show cyst's size, position, configuration and relation with the pancreas, also EUS guided FNA can be performed, so it has significance in diagnosing and distinguishing pancreatic pseudocyst.
