title: Evaluation of bilioenteric anastomosis using quantitative hepatobiliary scintigraphy.
abstract: OBJECTIVE
  The patterns of quantitative hepatobiliary scintigraphy for bilioenteric anastomoses have not been objectively defined. This study was undertaken to establish the patterns of quantitative hepatobiliary scintigraphy in the patients with bilioenteric anastomoses performed for repair of postcholecystectomy benign biliary strictures.
  
  
  METHODS
  37 patients with bilioenteric anastomosis (Study group) and 10 postcholecystectomy healthy subjects (Controls) underwent quantitative hepatobiliary scintigraphy. Study group patients were further categorized into: Group A (n=27) - normal clinical and biochemical parameters, and Group B (n=10) - abnormal clinical and/or biochemical parameters. On scintigraphy, time of maximal activity and time of clearance of half of the activity was calculated at the liver parenchyma and hepatic hilum. Time of appearance of activity in the intestine was also recorded.
  
  
  RESULTS
  There was no significant difference in the scintigraphic parameters between Group A and Controls except for earlier appearance of activity in the intestines (p=0.036) in Group A. In Group B there was significant increase in the time of clearance of half of the activity at the liver parenchyma and hepatic hilum compared to Controls (p=0.003 and 0.036 respectively), and at the liver parenchyma compared to Group A (p=0.002).
  
  
  CONCLUSIONS
  Quantitative hepatobiliary scintigraphic patterns in patients with bilioenteric anastomosis were similar to those of postcholecystectomy controls. Patients with abnormal biochemical parameters had significant delay in clearance of activity. Significance of these scintigraphic patterns in this subset of patients can be determined only on long-term follow-up.
