EUS Morphology Is Reliable in Selecting Patients with Mucinous Pancreatic Cyst(s) Most Likely to Benefit from Surgical Resection

Figure 1

Study cohort. Mucinous cyst criteria: (1) aspiration of thick mucus from the cyst, (2) CEA > 192 μg/ml, or (3) presence of mucinous epithelium in aspirate. Recommendation for surgery based on the presence of focal wall thickness, septa > 3 mm in thickness, cyst size ≥ 3 cm, cellular atypia, or adenocarcinoma on cytology or cyst fluid CEA > 500 ng/ml. Cysts with aspirates containing significant number of acute inflammatory cells were considered to be pseudocysts even if the aforementioned criteria were met. Adenocarcinoma included adenoca = 17 and IPMN high grade = 2. EUS-FNA: endoscopic ultrasound fine-needle aspiration; IPMN: intraductal papillary mucinous neoplasm.
