The 25-gauge FNA needle was significantly superior in terms of technical success rate and overall diagnostic accuracy, especially for the head and uncinate lesions, compared to the 22-gauge and Trucut needles and could be considered 'the best choice needle for cytological diagnosis' of solid pancreatic lesions. If histological diagnosis is required, the 22-gauge FNA needle and Trucut needle may be advantageous for use in head/uncinate and body/tail lesions, respectively.

This initial experience with a single session of percutaneous aspiration and ethanolamine oleate sclerosis resulted in sustained resolution of symptomatic polycystic liver disease with minimal morbidity, avoidance of surgery, and improvement in quality of life.

Concerning the sensitivity for detection of the hypovascular pattern in pancreatic adenocarcinoma, D-eFLOW (before and after USCA) had similar sensitivity to PD-EUS (before and after USCA) and CD-EUS (before and after USCA). D-eFLOW after contrast showed the highest accuracy (82.3 %) and negative predictive value (53.8 %) among all the modalities investigated. There was a good correlation among the ViVA scores for D-eFLOW before contrast, those for D-eFLOW EUS, and those for PD-EUS and CD-EUS. The reliability of the ViVA scale was excellent with an ICC of 0.81. In conclusion, D-eFLOW EUS is a sensitive, reliable, and highly accurate method of assessment of pancreatic vascularity. D-eFLOW EUS with contrast was more sensitive than PD-EUS and CD-EUS for assessment of pancreatic vascularity.
