Treatment of pancreatic pseudocysts.
According to the Atlanta classification an acute pseudocyst is a collection of pancreatic juice enclosed by a wall of fibrous or granulation tissue, which arises as a consequence of acute pancreatitis or pancreatic trauma, whereas a chronic pseudocyst is a collection of pancreatic juice enclosed by a wall of fibrous or granulation tissue, which arises as a consequence of chronic pancreatitis and lack an antecedent episode of acute pancreatitis. It is generally agreed that acute and chronic pseudocysts have a different natural history, though many reports do not differentiate between pseudocysts that complicate acute pancreatitis and those that complicate chronic disease. Observation--"conservative treatment"--of a patient with a pseudocyst is preponderantly based on the knowledge that spontaneous resolution can occur. It must, however, be admitted that there is substantial risk of complications or even death; first of all due to bleeding. There are no randomized studies for the management protocols for pancreatic pseudocysts. Therefore, today we have to rely on best clinical practice, but still certain advice may be given. First of all it is important to differentiate acute from chronic pseudocysts for management, but at the same time not miss cystic neoplasias. Conservative treatment should always be considered the first option (pseudocysts should not be treated just because they are there). However, if intervention is needed, a procedure that is well known should always be considered first. The results of percutaneous or endoscopic drainage are probably more dependent on the experience of the interventionist than the choice of procedure and if surgery is needed, an intern anastomosis can hold sutures not until several weeks (if possible 6 weeks).
