Aim:
To assess the usefulnes of EUS and complication in a newly-established GI-center.
Methods:
Our retrospective study included 565 EUS performed in 470 patients between 2015 –
2018. EUS indications, complication rate and performance for different diagnosis were
assessed.
Results:
Overall, interventional EUS rate was 37.1%. The number of EUS significantly increased
in 2017 – 2018. The main 3 EUS indications changed over time (Table). Overall, 23
complications in 22/565 (4%)EUS were reported: transient hypoxic respiratory failure:
1.4%, bleeding: 0.8%, pancreatitis: 0.5%, aspiration pneumonia: 0.3%, pancreatic drainage
dislocation: 0.3%, pancreatic abscess: 0.1%, sepsis: 0.1% and thrombosis of superior
mesenteric vein: 0.1%.
Choledocholithiasis was diagnosed in 36.4% of suspected cases. EUS showed a very good
performance: 100% PPV, 97.6% NPV and 98.4% accuracy.
EUS could identify a cause of pancreatitis in 62.5% of cases with initially unknown
etiology (45.8% biliary etiology, 8.2% pancreatic tumor and 4.5% pancreaticolithiasis
and autoimmunpancreatitis).
EUS-FNA accuracy for solid pancreatic masse was 51.9%, with lowest value in 2016 (27.2%),
and highest value in 2018 (79.3%).
Subepithelial tumors were confirmed by EUS in 64.4% of suspected cases. FNA was performed
in 35.8% of cases. The rate of conclusive histology was low (20.7%).
An intervention was performed in 69.2% of all pancreatic cysts (53.8% FNA, 9.9% Pigtail
drainage and 5.5% AXIOS®drainage).

Conclusion:
EUS is increasingly used in our Center with a low rate of complications and excellent
performance for detection of choledocholithiasis and provided an etiology in more
than half of patients with unknown cause of acute pancreatitis.
