Introduction:

Endoscopic ultrasound (EUS)-guided drainage and luminal-apposing metal stents (LAMS) are the options for managing symptomatic pancreatic pseudocysts.

Aim:

To evaluate the effectiveness and safety of LAMS for EUS-guided drainage of symptomatic pancreatic pseudocysts in two referral centers in Colombia.

Materials and methods:

A multicenter prospective cohort study between June 2019 and December 2021 included 13 patients diagnosed with symptomatic pancreatic pseudocysts who underwent EUS-guided drainage with LAMS. Technical success, clinical success, and successful stent removal were evaluated as outcomes. Safety outcomes included stent-related adverse events and general adverse events. Follow-up was carried out for eight weeks, collecting data on stent removal.

Results:

The average age was 53.4 years; 8/13 were men. The mean size of the pseudocyst was 9.56 ± 2.3 cm. Technical success was 100%, and clinical success was 92.3%. The stents were removed on average after 8 ± 2 weeks. The mean procedural time from puncture to stent deployment was 3.2 ± 2.4 minutes. In the imaging check-up, the collections had adequate drainage in all cases. There was a low frequency of complications; bleeding was documented in one case requiring surgery.

Conclusions:

LAMS is safe and effective in managing symptomatic pancreatic pseudocysts, reducing hospital stay and cost overruns. Clinical symptomatology prevails in the surgery decision.
