benign biliary strictures
All patients who have a medical indication for an ERCP to place a stent in their benign biliary strictures

Procedure: Endoscopic Retrograde Cholangiopancreatography (ERCP)
Endoscopic Retrograde Cholangiopancreatography (ERCP) with placement of metal stent in the bile duct
|
- Short Term Success Rate in the Resolution of Biliary Strictures [ Time Frame: 6 months ]Short-term success was defined as resolution of the stricture as documented by rapid drainage of contrast out of the proximal biliary tree and easy passage of stone extraction balloon inflated to the size of the proximal bile duct. If the biliary stricture had resolved at the 6-month follow-up ERCP, patients were classified as short-term success. If stricture was not resolved at 6-month ERCP then a new SEMS was placed; if the stricture had resolved at the time of the second stent removal, the patient was also classified as short-term success.
- Long-term Success Rate in Resolution of Biliary Strictures [ Time Frame: at least 12 months after stent removal ]Long-term success was defined as no clinical evidence of recurrence of the biliary stricture during the follow-up period as documented by laboratory findings or imaging and no further need for further endoscopic or surgical interventions.
- Number of Endoscopic Treatments Per Patient [ Time Frame: At time of procedure ]The average number of ERCPs performed per patient required for resolution of benign strictures.
- Ease of Stent Removal [ Time Frame: at time of procedure ]The ease of stent removal was graded on a 4-point scale (with ease, mild difficulty, significant difficulty, and failed).
- Frequency and Severity of Adverse Events (Including Stent Migration) [ Time Frame: up to 12 months ]Adverse events were defined and graded using the 2010 American Society for Gastrointestinal Endoscopy consensus criteria
