title: Biliary manometric perfusion test in the evaluation of benign biliary stricture treatment--a case report.
abstract: BACKGROUND
  Benign biliary strictures treated radiologically by percutaneous dilatation treatment are usually evaluated by 'clinical test'. For objective evaluation of treatment success, measurement of the pressure inside the biliary tree has been proposed.
  
  
  OBJECTIVE
  The aim of this article is to report our experience with the measurement of the pressure in the biliary tree after treatment, to present the biliary manometric perfusion test (BMPT) as an alternative method of treatment evaluation and to demonstrate why the perfusion test is a better method of evaluation.
  
  
  METHODS
  A 65 year old lady with post operative biliary stricture and symptoms of jaundice was treated in our Department with percutaneous dilatation treatment and long-term drainage. The perfusion test (BMPT) was adopted for evaluating treatment success after the treatment for 9 months. An intrabiliary pressure less than 20 cms of water during perfusion test was considered success threshold.
  
  
  RESULTS
  The test was carried out without any complications and the pressure inside the biliary tree was less than 20 cms of water during the test. Eventually the drain was removed. On follow-up at 6 months the patient developed no recurrence of jaundice and the quality of life improved clinically. Periodic liver function tests during follow-up were normal.
  
  
  CONCLUSIONS
  The perfusion test (BMPT) is promising efficacious alternative method for the evaluation of radiological treatment of benign biliary strictures. It helps us to decide the end points in treatment and also helps in identifying patients who might later develop strictures.
