ABSTRACT
BACKGROUND AND AIMS:
Differentiating pancreatic cystic lesions remains a challenge when the current technique of EUS-guided FNA is used. Recently, a miniaturized biopsy forceps with an outer diameter of 0.8 mm has been developed, thus allowing it to be passed through the bore of a standard 19-gauge FNA needle to acquire tissue.METHODS:
This study consisted of a retrospective review of all cases of EUS-guided through-the-needle forceps biopsy technique (TTNFB) performed for pancreatic cystic lesions at a single academic tertiary care center over a 12-month period. Technical success was defined as acquisition of adequate tissue for formal histologic analysis. Safety was assessed through the monitoring and recording of periprocedural and postprocedural adverse events.RESULTS:
The technical success of EUS-guided TTNFB was 87% (13/15). EUS-guided TTNFB with histologic analysis yielded pancreatic cyst diagnoses in 11 of 15 (73%) patients, compared with 0 of 15 (0%) patients with the use of EUS-FNA and cytologic analysis (P < .001). Of the 15 cystic lesions, 8 were diagnosed as intrapapillary mucinous neoplasm based on EUS-TTNFB.CONCLUSION:
This TTNFB technique has the potential to improve the diagnostic yield of EUS-FNA for pancreatic cystic neoplasms.
