AKUT PANKREATIT Roland Andersson 11 april 2014, Lund Fall 1 47-årig kvinna med övervikt, BMI 31, insulinbehandlad diabetes mellitus, inkommer med ett knappt dygns anamnes på smärtor i övre delen av buken. Pat har en känd gallstenssjukdom med upprepade stenanfall, ultraljudsverifierade multipla små konkrement i gallblåsan och står på väntelista för op. För knappt 3 mån sedan var pat inlagd pga en lindrig akut pankreatit men någon kolecystektomi har ännu ej kommit till stånd. Vid inkomsten har pat uttalade smärtor upptill i buken, bltr 90/65, puls ca 120/min och pankreasspecifikt amylas 15 ukat/l, CRP 147, bilirubin 53 och övriga leverparametrar något förhöjda.
