Brief Summary
The biliary system normally empties into the intestines, however, some patients have biliary system narrow areas ("stenosis") that prevent the bile to drain normally. These may be related to an underlying disease or previous surgery. Patients with this problem usually require tubes to be inserted into the biliary system to drain bile into a bag outside of their body, impacting their quality of life. The purpose of this research study is to use a laser device to try to re-open the biliary drainage system.

Outcome Measures
Primary Outcomes (1)
Number of patients free of post-interventional complications after use of the endo-biliary laser.
Patients will be assessed for safety after the endo-biliary laser use. Specifically, intraprocedural, immediate post-procedural (up to 4 hours), phone conversation 1 week post-procedure, and regularly scheduled 4 week post-procedure follow-up appointments will document the patient's tolerance of the procedure and any deviations from patients receiving biliary tube exchanges. Particular attention will be placed on regularly monitored signs/symptoms, such as cholangiographic appearance, total bilirubin, jaundice/fever/abdominal pain, etc. As each patient follows up on an \~4 week basis, any potential post-intervention complication will be documented.
up to 100 weeks
Secondary Outcomes (2)
Technical success of endo-biliary laser excision via cholangiographic imaging.
up to 100 weeks
Number of patients able to have internal-external biliary drainage catheters removed after endo-biliary laser excision.
up to 100 weeks
Study Arms (1)
Benign Biliary Stenosis, Laser
EXPERIMENTALSubjects that undergo the experimental intervention, that being single use of a laser excision catheter.
Interventions
Single use of laser to attempt excision of biliary ductal tissue causing stenosis.
Eligibility Criteria
You may qualify if:
- Subjects with diagnosed benign biliary stenosis
- Initial total serum bilirubin \> 1.9 mg/dL
- Subjects currently having an internal/external percutaneous biliary drain
- Subjects that have failed at least 3 separate biliary stenosis balloon angioplasties and are deemed non-surgical candidates by the transplant and/or pancreaticobiliary surgical services at the University of Florida
