BACKGROUND: The aim of this study was to assess the safety and utility of endoscopic treatment of pancreatic pseudocysts. Prognostic factors for the outcome of endoscopic drainage were assessed in a prospective analysis. METHODS: Forty-nine consecutive symptomatic patients were included in the study. Transmural drainage was used in 30 patients and transpapillary drainage in 19 patients. RESULTS: Successful drainage was achieved in 27/30 (90%) of patients after transmural drainage and in 16/19 (84.2%) patients after transpapillary drainage. Twelve (24.5%) patients had complications; 2 patients had bleeding, 2 had mild pancreatitis, 8 had cyst infection, in relation to the presence of necrosis (5 patients) or stent clogging (3 patients). Nine patients (20.9%) had recurrence of pseudocyst. Endoscopic drainage was a definitive treatment in 37 out of 49 (75.5%) patients (median follow-up: 25.9 months). Presence of necrosis was the only significant prognostic factor for infectious complication. CONCLUSIONS: Endoscopic drainage provides a successful and safe minimally invasive approach to the management of pancreatic pseudocysts.
