BACKGROUND: The management of small pancreatic cystic lesions presents a clinical challenge. METHODS: We reviewed our experience with 78 patients who presented with a cystic pancreatic lesion who underwent operative management between 1995 and 2005. Data on cyst characteristics were analyzed in the context of pathologic findings following resection. RESULTS: Among 78 patients, there were 55 (71%) females; median age 63 years. Patients presented with: an incidental finding (48%), pain (40%), acute pancreatitis (4%), other (8%). Operations were distal pancreatectomy (n = 47), pancreaticoduodenectomy (n = 16), and other (n = 15). Most patients had a non-malignant lesion (n = 65, 83%) (mucinous cystadenoma (n = 29), serous cystadenoma (n = 15), IPMN without invasion (n = 8), pseudocyst (n = 8), other benign (n = 5)). Malignant lesions (adenocarcinoma, neuroendocrine tumor, and other) were found in 13 patients (17%). The risk of malignancy increased with size: <3 cm (n = 25), 4%; 3-5 cm (n = 23), 13%; and >5 cm (n = 30), 30%. Pre-operative cyst fluid cytology was performed in 41 patients. The negative predictive value (NPV) of cytology for malignancy was 88% and the positive predictive value (PPV) was 80%. The NPV of CA 19-9 for malignancy was 90%; the PPV was 50%. CONCLUSIONS: Initial conservative management of small cystic pancreatic lesions may be indicated in selected patients. (c) 2009 Wiley-Liss, Inc.
