title: Carcinoma involving the gallbladder in elderly patients presenting with acute cholecystitis.
abstract: BACKGROUND
  The unexpected intraoperative finding of a cancerous gallbladder has become particularly problematic, because cancer recurs rapidly after laparoscopic cholecystectomy. It would be desirable to identify the patients of greatest risk for gallbladder cancer before operation. After several elderly patients presenting with acute cholecystitis were found to have gallbladder cancer, we performed the following study.
  
  
  METHODS
  Records of patients (60 years of age or older, 1987 to 1995) with an admitting diagnosis of acute cholecystitis and symptoms including right upper quadrant pain, nausea, vomiting, fever, and leukocytosis were reviewed.
  
  
  RESULTS
  Eighty patients were included in the study. Carcinoma involving the gallbladder was found in seven patients; six had primary and one had metastatic carcinoma. The 73 patients without cancer underwent cholecystectomy. The differences between the noncancer and cancer patients included age (68 +/- 7 versus 74 +/- 8 years, p < 0.05), total bilirubin (mg/dl, 1.5 +/- 1.5 versus 3.7 +/- 3.4, p < 0.01), alkaline phosphatase (IU/L, 179 +/- 132 versus 369 +/- 226, p < 0.01), and aspartate aminotransferase (IU/L, 77 +/- 93 versus 158 +/- 157, p < 0.05).
  
  
  CONCLUSIONS
  Additional work-up and open cholecystectomy should be considered in elderly patients presenting with apparent acute cholecystitis, especially when liver functions are abnormal.
