The Authors present a case of post traumatic pseudocyst of the pancreas added to their observations and treated with an endoscopic cytogastric deviation. The incidence of such pathology has increased during the last few years thanks also to the improvement of the diagnostic techniques (TAC, U/S, Rm and eco-endoscopy) on hard today; in the second place the technological evolution has allowed, improving the diagnostic definition, the ability to heat pseudocysts, in selected patients, with minor surgery techniques with result equal to those of conventional surgery, but with complications and mortality decisively reduced. The morbidity and mortality rates of internal deviation surgery has respectively worsened varying between 21% and 50% and from 5% to 12%. The results of endoscopic deviations, even if the cases are less, report positive results from 80% to 100%, with complications and mortality greatly reduced. To be able to propose an endoscopic indication certain requirement are necessary of which one is indispensable: the distance between the two adjacent lumen must not be more than one centimeter. The Authors are of the opinion that such methods, in expert hand an on selected patients, should be the first surgical choice for the treatment of pancreatic pseudocysts.
