title: Pyogenic liver abscess in Crohn's disease.
abstract: We describe six cases of pyogenic liver abscess occurring among 1227 Crohn's disease patients admitted to The Mount Sinai Hospital from 1960 through 1982, and review the features of the seven similar cases that have been previously reported. Mechanisms of formation of liver abscess in these 13 patients included direct extension of intraabdominal abscess (three cases), propagation via the portal vein (eight cases), biliary complications (one case), or metastatic cancer (one case). Five of the 13 patients died. All five deaths occurred among the eight patients with multiple abscesses; all five patients with solitary abscess survived. The mean age of the patients who died was 56 years, versus 37 years for the survivors. Three of the four patients treated with antibiotics only died; only two of the nine patients who underwent some form of drainage succumbed. Mortality was usually attributable to failure in making the diagnosis, especially as liver function test abnormalities were often subtle. Furthermore, the generally nonspecific clinical signs and symptoms were often obscured by underlying bowel disease. If a high index of suspicion is maintained, CT scanning and ultrasonography should reveal the lesion at an early stage, so that the necessary drainage procedure can be carried out, with or without concomitant resection of affected bowel and drainage of intraabdominal abscess.
