Brief Summary
The purpose of this study is to determine if cholangioscopically-directed biopsies provide a higher diagnostic yield for malignancy in the setting of indeterminate biliary strictures when compared to standard means of sampling.

Outcome Measures
Primary Outcomes (1)
Number of malignant diagnoses across hree-sample techniques (Spy bite, forceps biopsy, brushings)
Accuracy, sensitivity, and specificity of the three-sample technique (Spy bite, forceps biopsy, brushings) compared to the two-sample technique (forceps biopsy and brushing) in differentiating malignant from benign biliary strictures
72 Hours
Secondary Outcomes (3)
Number of patients who receive additional diagnostic studies without receiving a cancer diagnosis
1 year
Endoscopic Satisfaction with SOC-directed biopsy
2 hours
Time from procedure to the initiation of treatment (in cases of malignancy)
1 year
Study Arms (2)
Standard
NO INTERVENTIONStandard of care biopsies with optional SOC-directed biopsy afterwards
Study
EXPERIMENTALSOC-directed biopsies using the SpyGlass System plus standard of care biopsies
Interventions
The cholangioscopy procedure with the SpyGlass System is performed by a single operator with the SpyScope Access and Delivery Catheter positioned just below the operating channel of the duodenoscope. SpyBite Biopsy Forceps guided by the SpyScope Catheter are introduced and endoscopic-guided biopsy is taken at the level of the stricture. Target lesions will be identified under direct visualization using the SOC system, and 6-8 bites will be performed with the SpyBite forceps. Once SOC-directed biopsies are obtained, the SOC system will be withdrawn into the working channel of the duodenoscope and removed Patient will be contacted monthly to determine if they have undergone any additional procedures and to record potential adverse events.
Eligibility Criteria
You may qualify if:
- Age greater than or equal to 18 years
- Presence of indeterminate biliary strictures with clinical indications for ERCP. Strictures are considered indeterminate when evaluation including cross-sectional imaging is non-diagnostic. Patients who have previously undergone ERCP with sampling will be included, as well as those who have not previously undergone ERCP.
- Strictures located above the intrapancreatic bile duct
- The Subject's physician determines and ERCP is clinically indicated
- Able to provide informed consent
You may not qualify if:
- Prior enrollment in the study or another study evaluating biliary strictures
- Presence of extrahepatic malignancy or previously-diagnosed hepatocellular carcinoma
- Pregnancy
- At-risk populations including prisoners and mentally challenged
- Unwilling to provide informed consent
- Medically unfit to undergo ERCP
- History of liver transplant
