Ascending cholangitis as a cause of pyogenic liver abscesses complicated by a gastric submucosal abscess and fistula.

Ruptures of nonamebic (pyogenic) liver abscesses into the thorax and peritoneum are very uncommon; but, hepatoduodenal and hepatocolonic fistulas are ever more rare. We report a case where ascending cholangitis was associated with pyogenic liver abscess formation and a gastric fistula. Drainage into the stomach was demonstrated by gastroduodenal endoscopy for gastric bleeding. After fistula formation, we could successfully treat the inflammation caused by infection of Citrobacter freundii and Candida albicans with intravenous infusion of both antibiotic and antifungal agents.
