Prospective evaluation of slow-pull with fanning technique in EUS-guided fine needle aspiration on pancreatic masses.
2018
232Background: Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is useful in obtaining pancreatic mass samples. Combination of modified techniques (slow-pull technique and fanning technique) may improve the sample quality obtained by EUS-FNA. We investigated the effectiveness of a slow-pull with fanning technique in EUS-FNA for pancreatic mass. Methods: This prospective comparative study investigated EUS-FNA for pancreatic solid masses from August 2015-July 2016. The pairwise specimens were alternately obtained using two techniques: standard suction or slow-pull with fanning for target pancreatic lesions. We compared the specimen quality, blood contamination, and diagnostic yield of these techniques. Results: Forty-eight consecutive patients were enrolled (29 men; mean age, 68.1±11.9 years), and 96 pancreatic mass specimens were obtained. The slow-pull with fanning technique had significantly superior diagnostic accuracy than the suction technique (88% vs. 71%, p = 0.044). Further, blood co...
