A 75-year-old man with diabetes and previous kidney transplant was evaluated for a 4.6 × 4.4-cm pancreatic body cyst (A) that had increased from 3.7 × 3.3 cm over 3 years on serial computed tomography scans. Given his comorbidities, social circumstances, and the need to minimize repeated procedures, we combined real-time diagnosis and risk stratification using endoscopic ultrasound—guided needle-based confocal laser endomicroscopy (nCLE), with potential for same-session EUS-guided radiofrequency ablation (RFA) on the basis of findings.
EUS-nCLE with the AQ-Flex miniprobe (Cellvizio; Mauna Kea Technologies, Paris, France) revealed features of a branch duct intraductal papillary mucinous neoplasm with flat epithelium and monolayered nuclei, consistent with low-grade dysplasia (B). After cyst aspiration, EUS-RFA was performed using a 19-gauge EUSRA 10-mm probe (TaeWoong Medical, Los Angeles, Calif, USA) and the VIVA pump (STARmed American, Los Angeles, Calif, USA) at 50W in continuance mode. A total of 18 applications were delivered (mean: 41.3 seconds/application) (C).
The cyst volume decreased from 41.9 to 3 mL postablation, indicating a 91.6% volumetric response. Postablation next-generation sequencing showed resolution of preexisting mutations, confirming a complete molecular response. This case highlights the feasibility of combining EUS-nCLE and EUS-RFA in a single session, a minimally invasive approach that may improve outcomes and resource use in high-surgical-risk patients.
