Based on the classification of pseudocysts according to D'Egidio and Schein the different surgical techniques for the treatment of pancreatic pseudocysts, i.e. drainage procedures and resections are discussed. The role of laparoscopic techniques is demonstrated. The "competing" endoscopic and interventional techniques are mentioned. The prognosis of the patients after operations for pancreatic pseudocysts is to a smaller degree depending on the operating technique, but largely on the natural history of the disease and the discontinuation or continuation of the underlying pathogen.
