Pancreatic pseudocysts. Clinical contribution

Aim of this study was to compare, taking into consideration data from the literature, the various diagnostic examinations and therapeutic modalities nowadays available to manage patients affected by pancreatic pseudocysts. Personal experience regarding three patients with post-necrotic pancreatic pseudocysts is reported; these patients complained of epigastric pain with nausea and tenderness in the upper abdominal quadrants. Diagnosis was made by CT. In one case a progressive decrease of the pseudocyst was observed; the second patient was treated by a pseudocyst-jejunostomy; the last patient initially underwent a trans-gastric percutaneous drainage for infection of the pseudocyst and afterwards an open pseudocyst-gastrostomy. All patients were cured, even if the second patient during the postoperative course developed a pleuric effusion, which was treated by thoracentesis. Pancreatic pseudocysts in 20% of cases resolve spontaneously, as observed in one of our patients. In other cases, a surgical operation is needed, now feasible through an endoscopic, percutaneous, laparotomic or laparoscopic approach. The endoscopic and percutaneous approach are indicated only in selected cases, so that the "gold standard" treatment is still the laparotomic one, especially by a pseudocyst-jejunostomy, which also in our experience has given the best result. Very promising also, according to the latest data from the literature, seems the laparoscopic approach, by which a wide communication between the stomach and the pseudocyst is obtained.
