[Vascular problems in destructive pancreatic surgery].
Obstacles of vascular type may hinder or prevent pancreatic destruction for tumours of the pancreas or periampullary tumours. Out of 72 major pancreatic demolitions (cephalic duodenopancreatectomy or subtotal pancreatectomy from rt to lt) there were vascular difficulties on 26 occasions (36%), of which 15 were in existence prior to development of the neoplasia (anomalies of rise and course of peripancreatic vessels, stenosis/obliteration of the common hepatic artery in pancreatic head or periampullary tumours) and 11 due to tumoral growth (direct involvement of the mesenteric-portal tract, the hepatic artery and the superior mesenteric artery). The technical solutions used are discussed individually in the light of the physiopathological repercussions consequent on any temporary or permanent interruption of important hepatic and splanchnic vascularisation vessels (hepatic artery and various mesenteric a.), in relation to operating mortality and the prospects of long-term survival. In the most complex cases of direct vascular involvement by the neoplasia, the Author's trend was orientated to a position which, while accepting demolition decisions useful for the widening of the surgical radicality margins, nevertheless avoids extensive demolition solutions imposed by conditions of necessity or considerations of principle that probably do not bring significant advantages as regards long-term prognosis for these tumours.
