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.
Biliary strictures in the absence of a mass are a clinical challenge, as current accepted means of sampling provide suboptimal accuracy. Both biliary brushings for cytology and fluoroscopically-directed biopsies produce highly-variable results. Endoscopic ultrasound with fine-needle aspiration has also been employed with variable results. An additional modality, using a single-operator cholangioscope during endoscopic retrograde cholangiopancreatography (ERCP) to obtain cholangioscopically-directed biopsies offers promise in increasing the yield of sampling. Initial observational studies have shown an improved diagnostic yield, but the technique has not been tested in a randomized, medical effectiveness study to better characterize its actual clinical impact. We aim to compare the technique of biopsy-on-biopsy derived sampling via single-operator cholangioscopy with standard fluoroscopically-directed biopsies and brushings in a pilot study. We also aim to perform a medical effectiveness study on the early use of single-operator cholangioscopically (SOC) in the evaluation of undiagnosed biliary strictures.

| SOC-directed biopsies using the SpyGlass System | Device | 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 Once SOC-directed biopsies are obtained, the SOC system will be withdrawn into the working channel of the duodenoscope and removed Patient will be contacted monthly to determine if they have undergone any additional procedures and to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. |
