All patients underwent EUS\u2010FNA successfully; however, changing of the echoendoscope to a forward\u2010viewing echoendoscope and preplacement of a nasobiliary catheter by balloon\u2010assisted enteroscopy for guidance were needed in one and two cases, respectively. The median procedure time was 26\u00a0min (range, 16\u201370). The diagnostic accuracies were 76%, 84%, and 88% for cytology, histology, and combined use, respectively.
