The use of endoscopic ultrasound in the management of post-surgical and pancreatic fluid collections.

Fluid collections after abdominal surgeries, particularly pancreatic surgeries, are associated with high morbidity and mortality. Up until recently, percutaneous drainage was the first line therapy, but not without disadvantages, including high maintenance, risk of infection and chronic fistulas, electrolyte losses, and impact on quality of life. Endoscopic ultrasound (EUS)-guided drainage of post-surgical fluid collections (PSFCs) is safe and effective, carrying similar success, adverse event (AE), and recurrence rates as percutaneous drainage. Despite limited data on EUS-guided drainage of PSFCs, especially with regards to direct comparisons to percutaneous drainage, EUS management of these collections is becoming the first-line approach in many expert institutions.
