EUS‐guided tissue acquisition using a novel torque technique is comparable with that of the fanning technique for solid pancreatic lesions: A multicenter randomized trial

摘要

Abstract Background The torque and fanning techniques allow for multiple areas within pancreatic lesions to be targeted using different maneuvers and can, hence, enhance diagnostic outcomes. We compared the diagnostic performance of endoscopic ultrasound‐guided fine‐needle biopsy (EUS‐FNB) for pancreatic masses using the torque and fanning techniques. Methods This multicenter randomized trial enrolled a total of 160 consecutive patients who underwent EUS‐FNB for solid pancreatic tumors using either the torque or fanning technique. Three passes were permitted for each lesion, and the technique sequence was randomly assigned as either torque first or fanning first with the standard technique as a reference. Results The median quality score of the histological samples was significantly higher in the torque and fanning group than in the standard group (p?
