title: Cholecystectomy in patients with Crohn's ileitis.
abstract: OBJECTIVE
  Gallstone disease is reported to be higher in patients with Crohn's disease than in the general population. This study was designed to determine the prevalence of cholecystectomy in patients with Crohn's ileitis, attempt to identify any associated risk factors, and determine whether it is justified to perform prophylactic cholecystectomy during ileocolic resection.
  
  
  METHODS
  A total of 191 patients with Crohn's ileitis who were treated medically or who had an ileocolic resection were retrospective reviewed. A questionnaire survey was performed. Telephone interviews were conducted for the non respondents. Further review of medical records was performed to determine the details of admissions for any gallstone disease and/or subsequent cholecystectomy. A control group matched for age and gender was obtained.
  
  
  RESULTS
  A total of 191 questionnaires were mailed, and the overall response rate was 70.2 percent (134/191) after telephone interview follow-up. There were 2 of 45 medical and 18 of 89 surgical patients with symptomatic cholelithiasis, i.e., 14.9 percent (20/134) of respondents. As a result, 2 patients (1.5 percent) required endoscopic sphincterotomy, 17 patients (12.7 percent) needed cholecystectomy, and 1 patient (0.7 percent) did not have any intervention. Only five patients had a cholecystectomy after their ileal resections. In the control group of 150 patients, 15 patients (14 females; mean age, 51.9 years; range, 34-78 years) had previous cholecystectomy. There was no significant difference with prevalence of cholecystectomy in Crohn's patients compared with controls (17/134 vs. 15/150; P = not significant). Furthermore, the number of ileal resections did not affect the cholecystectomy rate, but patients who had >30 cm of ileum resected were more likely to have cholecystectomy (P = 0.056).
  
  
  CONCLUSIONS
  The prevalence of gallstone disease in Crohn's ileitis requiring cholecystectomy is similar to that of the general population with a female predominance. In addition, the number of patients requiring cholecystectomy after ileal resection was low. Thus, synchronous prophylactic cholecystectomy during ileocolic resection for Crohn's ileitis is not justified.
