Two-step endoscopic transmural drainage of pancreatic pseudocysts

Background: Pancreatic pseudocysts are a major complication of chronic and acute pancreatitis and often require endoscopic intervention. The aim of this study was to evaluate the technical results and clinical outcome of two-step endoscopic transmural drainage in patients with symptomatic pancreatic pseudocysts measuring >4cm. Methods: Four consecutive patients with pancreatic pseudocysts underwent endoscopic transmural drainage in 2011. The pseudocyst was first identified endosonographically. Potentially interposed vessels giving rise to a higher risk of bleeding were ruled out by color Doppler examination. The…
