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.
