- Abstract
Background: Histologic diagnosis of cystic pancreatic lesions (CPLs) is often difficult because of the low sensitivity of FNA and brush cytology. Objective: To discover whether obtaining biopsy samples from the cystic wall could increase the diagnostic yield of these lesions. Design: A pilot study including 2 patients with CPLs. Setting: Endoscopy unit in a tertiary-care hospital. Patients: Two women with CPLs located at the pancreatic head. Interventions: On EUS, biopsy forceps and a SpyGlass fiberoptic were passed through a 19-gauge needle to visualize and obtain samples from the cystic wall. Main Outcome Measurements: The histologic assessment was based on the obtained biopsy samples. Results: Both CPLs were considered to be mucinous cystoadenomas, because mucinous-like cylindric epithelium without cellular atypia was observed. Limitations: Pilot study. Conclusions: Obtaining biopsy samples from the wall of a CPL is now feasible. It represents a significant advantage in the diagnostic yield of this type of lesion. [ABSTRACT FROM AUTHOR]
