With the increased use of cross sectional imaging, there appears to be an increasing prevalence of pancreatic cysts being incidentally discovered.
A critical step in the workup of pancreas cysts is to determine whether the cyst is mucinous or non-mucinous, through a procedure called endoscopic ultrasound - fine needle aspiration (EUS-FNA).
Current guidelines suggest the use of antibiotics in cyst aspiration, usually 3 days after the procedure. However, these recommendations are based on limited data from over 15 years ago. More recent retrospective observations suggest equivalent safety when little, or even no antibiotics are given.
