ObjectivesThis consensus was developed by the Asian EUS Group (AEG), who aimed to formulate a set of practice guidelines addressing various aspects of endoscopic ultrasound‐guided tissue acquisition (EUS‐TA).MethodsThe AEG initiated the development of consensus statements and formed an expert panel comprising surgeons, gastroenterologists, and pathologists. Three online consensus meetings were conducted to consolidate the statements and votes. The statements were presented and discussed in the first two consensus meetings and revised according to comments. Final voting was conducted at a third consensus meeting. The Grading of Recommendations, Assessment, Development, and Evaluation system was adopted to define the strength of the recommendations and quality of evidence.ResultsA total of 20 clinical questions and statements regarding EUS‐TA were formulated. The committee recommended that fine‐needle biopsy (FNB) needles be preferred over conventional fine‐needle aspiration (FNA) needles for EUS‐TA of subepithelial lesions. For solid pancreatic masses, rapid on‐site evaluation is not routinely recommended when FNB needles are used. For dedicated FNB needles, fork‐tip and Franseen‐tip needles have essentially equivalent performance.ConclusionThis consensus provides guidance for EUS‐TA, thereby enhancing the quality of EUS‐TA.

Background and Objectives: EUS is widely used in the clinical practice. This study aimed to evaluate the efficacy of a novel echoendoscope regarding image quality, maneuverability, stability of the entire machine system, and safety. Setting and Design: We conducted this open-label, multicenter, randomized, parallel-group, noninferiority clinical trial in three tertiary hospitals between November 2018 and April 2019. Subjects and Methods: One hundred and thirty patients were included. The stratified segment randomization method was employed. Sixty-five patients in the test group received an EUS examination using the new material radial echoendoscope, and 65 patients in the control group received an EUS examination using the existing endoscope. We recorded the image quality, maneuverability, stability of the entire machine system, and safety. For the main outcome, comprehensive image quality, the groups were compared with the noninferiority test, using the confidence interval method and 10% as the noninferiority threshold. The Pearson Chi-square test was used to compare the incidence of adverse events between the groups. Results: Sixty-five patients in the test group and 63 patients in the control group were analyzed. Two patients in control group did not complete an EUS examination due to machine problems. There were no significant differences in image quality, maneuverability of the echoendoscope, stability of the entire machine system, and safety between the groups. Conclusions: This new material radial echoendoscope showed good capabilities for image quality, maneuverability, stability of the entire machine system, and safety. Our data suggest that the new echoendoscope may provide an additional option for endoscopic physicians.

A prospective, controlled assessment of the technical characteristics of a novel forward-viewing echoendoscope

Abstract: the FV-CLA allows a complete, high-quality examination of the upper GI tract, including EUS-FNA punctures. Some mediastinal stations are hardly accessible with this new device. A formal validation of the FV-CLA for EUS-guided therapy would be of interest.
