Abstract
OBJECTIVE: To compare the efficiency of plastic and metal stents for symptomatic pancreatic pseudocyst (PP) drainage and analyze other main associated factors that affect the outcome of drainage therapy. METHOD: Rates of technical and clinical success, procedure-related side effects (hemorrhage, stent migration, and cyst rupture), reinterventions, and duration of hospital stay. RESULTS: There were 52 patients, 40 patients underwent plastic stent placement and 12 patients underwent lumen-apposing metal stent (LAMS) placement. The total rate of technical success was 100%. The total rate of clinical success was 100%. The total rate of adverse events was 7.7% (4/52). On multiple logistic regression analysis, the use of plastic stents (P < 0.05, Exp B = 12.168) and the presence of a large cyst (P < 0.05, Exp B = 1.036) were shown to significantly increase the risk of reintervention. On multivariate linear regression analysis, etiology of pseudocyst (P < 0.05, B = -8.427, -9.785, -5.514) was associated with prolonged hospital stent, while stent type was not shown be a factor (P > 0.05). CONCLUSION: Both plastic and LAMSs are proven to be highly efficient in PP drainage. The LAMS is superior in preventing complications such as migration and cyst leakage and reducing the rate of reintervention.
