[Treatment of early and late complications of surgery of pancreatic pseudocysts].

Among 45 operations for pseudocysts the authors report 9 cases of complications, three of them early (haemorrhage and acute pancreatic necrosis) and six delayed (persistence of fistulae and relapse); in six of these surgery was performed and two of them died. Among the different types of surgery performed, external drainage proved to be the one most burdened by complications (2/3 of cases), while their incidence was far lower in internal shunt (2 cases out of 28) and cysto-parenchmal demolitions (one case out of eight). Attention is drawn to the danger of post-operative haemorrhage and the need to combat this complication with decision. For recurring pseudocysts and for fistulae which do not benefit from conservative treatment, the surgical operation, when it does not result in demolition, must be capable of correcting the canalicular alterations of the base pancreatitis.
