Pancreatic and hepatic abscesses: a late complication in 10 patients with chronic pancreatitis

Abstract

In this prospective long-term study of chronic pancreatitis (n = 336) over the last 3 decades, 10 patients with advanced calcific pancreatitis developed a sepsis associated with intra-abdominal abscesses (6 pancreatic, 4 hepatic). None of the known precipitating factors were present (e.g., no pancreatic necrosis or recent surgical/endoscopic interventions, no evidence of cholangitis). Nine of 10 patients had alcoholic chronic pancreatitis. Interestingly a pancreatojejunostomy in 9 of 10 patients had been performed up to 12 years previously. Cultures from abscess aspirates and/or blood were polymicrobial, mainly a mixed enteric flora in 8 patients. All patients recovered after an appropriate antibiotic therapy with or without drainage procedures. The pathogenesis of "spontaneous" abscess formation in advanced chronic pancreatitis and its relationship to pancreatojejunostomy remain to be established.
