Experience in the Management of Peripancreatic Collections Using Endoscopic Ultrasound in a Tertiary Referral...

Acute pancreatitis (AP) accounts for approximately 230,000 hospital admissions per year in the United States alone. Peripancreatic fluid collections (PFCs) are recognized complications of AP. Currently, the management of PFCs has evolved toward a minimally invasive step-up approach, in which endoscopic ultrasound (EUS)-guided drainage has progressively become the standard of care.

A retrospective observational study was conducted, including patients with peripancreatic collections who underwent EUS-guided drainage over a three-year period at the Hospital Regional de Alta Especialidad Bicentenario de la Independencia, Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE), located in Tultitlán, State of Mexico, Mexico.

A total of 35 patients underwent EUS-guided endoscopic drainage of peripancreatic collections. The mean age was 49.68 ± 12.90 years, and female patients were slightly predominant (51.4%). Pancreatic pseudocyst was the most frequent type of collection, observed in 65.7% of cases (n = 23), while walled-off necrosis (WON) accounted for 34.3% (n = 12). The most commonly used stent was the double pigtail plastic stent, employed in 60.0% of patients, compared with the lumen-apposing metal stent (LAMS), used in 40.0%. The mean stent indwelling time was 35.31 ± 9.58 days, with a mean post-procedure hospital stay of 3.5 days. Technical success was achieved in 100% of cases. Only three recurrences were observed (8.6%). Complications occurred in 5.8% of patients, and no 30-day mortality was reported (n = 0).

EUS-guided endoscopic drainage of peripancreatic collections demonstrated high efficacy and an acceptable safety profile.
