Abstract

Background: Distinguishing serous cystadenoma, a benign pancreatic cyst, from potentially malignant mucinous pancreatic cystic lesions carries significant clinical and prognostic implications; and while endoscopic ultrasound-guided fine needle aspiration is the standard diagnostic tool, its low diagnostic yield often results in additional workup.

Objective: This study evaluates diagnostic yield of fine needle biopsy (FNB) on lesions suggestive of serous cystadenoma on endoscopic ultrasound.

Methods: Patients with microcystic EUS appearance were identified through retrospective chart review in two institutions. Prior cross sectional imaging diagnosis was also obtained. All microcystic lesions with classic "honeycomb" appearance for serous cystadenoma on EUS were targeted for FNB and their pathology evaluated. Patients were identified through database search from 2015 to 2022 and procedure information was obtained through a retrospective chart review from two large academic centers.

Results: Thirty-one patients with suspected serous cystadenoma who underwent EUS-FNB were included. EUS FNB was successful in obtaining diagnosis in 96.8% of patients. Serous cystadenoma was diagnosed via EUS FNB in 27 of 31 patients (87.1%). Of the remaining four patients, there was one invasive pancreatic ductal adenocarcinoma, one pancreatic neuroendocrine tumor, one intraductal papillary mucinous neoplasm, and one nondiagnostic sample.

Conclusion: EUS-FNB sampling for histopathology is a safe and accurate diagnostic tool for pancreatic serous cystadenoma. When microcytic lesions are found on endoscopic ultrasound, our study results suggest that fine needle biopsy for histopathology should be considered as the initial diagnostic evaluation tool given the demonstrated improved diagnostic yield for serous cystadenoma.

期刊介绍: Pancreas provides a central forum for communication of original works involving both basic and clinical research on the exocrine and endocrine pancreas and their interrelationships and consequences in disease states. This multidisciplinary, international journal covers the whole spectrum of basic sciences, etiology, prevention, pathophysiology, diagnosis, and surgical and medical management of pancreatic diseases, including cancer.
