Original ArticlesMacrocystic pancreatic cystadenoma: the role of EUS and cyst fluid analysis in distinguishing mucinous and serous lesions
Section snippets
Patients
The clinical and EUS characteristics, as well as analysis of cyst fluid obtained by EUS-guided FNA (EUS-FNA), were retrospectively studied in 41 consecutive patients who presented between 1995 and 2002 with mucinous or macrocystic serous cystadenoma of the pancreas. All patients underwent endoscopic examinations and surgical procedures after written informed consent was obtained.
Inclusion criteria
The surgical pathology diagnosis (from histopathology files) was available for 32 patients with mucinous cystadenoma
Results
Data were available for 41 EUS examinations (41 patients). Patient characteristics and mode of presentation for mucinous cystadenoma (n = 32) and macrocystic serous cystadenoma (n = 9) were similar in both groups (Table 1).
Discussion
With better knowledge of the morphologic aspects of pancreatic cystadenomas, management strategies can be expected to improve. Unfortunately, EUS data for these lesions are limited. Until recently, pancreatic cystic tumors presenting as predominately unilocular macrocysts were resected surgically. The recent description of a macrocystic form of serous cystadenoma3., 4., 5., 6., 7., 8., 9., 10., 11., 12., 13., 14., 15., 16., 17. necessitates re-evaluation of morphologic data and expanded
