Background: Benign biliary strictures treated radiologically by percutaneous dilatation treatment are usually evaluatedby ‘clinical test'. For objective evaluation of treatment success, measurement of the pressure inside the biliarytree has been proposed.Aim: The aim of this article is to report our experience with the measurement of the pressure in the biliary tree aftertreatment, to present the biliary manometric perfusion test (BMPT) as an alternative method of treatment evaluationand to demonstrate why the perfusion test is a better method of evaluation.Materials and Methods: A 65 year old lady with post operative biliary stricture and symptoms of jaundice was treatedin our Department with percutaneous dilatation treatment and long-term drainage. The perfusion test (BMPT) wasadopted for evaluating treatment success after the treatment for 9 months. An intrabiliary pressure less than 20 cmsof 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 than20 cms of water during the test. Eventually the drain was removed. On follow-up at 6 months the patient developedno recurrence of jaundice and the quality of life improved clinically. Periodic liver function tests during follow-upwere normal.Conclusion: The perfusion test(BMPT) is promising effi cacious alternative method for the evaluation of radiologicaltreatment 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.
