Abstract
PALOS-CUELLAR, Raquel et al. Does biliary stent impacts on diagnostic tissue acquisition when Endoscopic Ultrasound Guided Fine Needle Aspiration Biopsy (EUS-FNA) is performed in patients with pancreatic and biliary masses?. Endoscopia [online]. 2020, vol.32, n.1, pp.20-23. Epub Oct 04, 2021. ISSN 2444-6483. https://doi.org/10.24875/end.20000014.
Background and objectives:
The American Society of Gastrointestinal Endoscopy recommends performing Endoscopic Ultrasound (EUS) for patients with suspicious pancreatic or biliary masses for adequate staging and tissue acquisition. However, it has not been determined if biliary stenting affects EUS guided tissue acquisition.
Patients and methods:
Retrospective, transversal, observational and analytic study from patients with pancreatic and biliary neoplasms who underwent EUS guided fine needle biopsy were compared for difference between those who had biliary stent versus those who did not have stent.
Results:
One hundred and eighty-three patients were included. General EUS guided tissue acquisition was 89.6% in patients with pancreatic and biliary neoplasm. There was no difference on tissue acquisition for patients with and without biliary stent (with stent 87.2% vs. without stent 90.5% p = 0.13).
Conclusions:
EUS guided tissue acquisition on pancreatic and biliary neoplasms is not affected by biliary stent.
