Biliary Obstruction Due to Common Bile Duct Stone, Biliary Stricture, Hemobilia, Periampullary Tumor
Conditions
Brief summary
The purpose of this study is to document indications for cholangioscopy and clinical utility of the SpyGlass Direct Visualization System (DVS) throughout the AMEA (Asia, Middle-East, Africa) region when used per standard of practice.
Interventions
ERCP procedure will be performed to visualize bile ducts.
DEVICESpyGlass DVS and SpyGlass Digital Simple (DS)
Cholangioscopy using SpyGlass™ DVS or SpyGlass DS will be performed post ERCP for direct viewing of the bile ducts. What is seen during the procedure will determine a course of treatment. Among the options are biopsies taken, stones treated/removed, or a stent placed

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Procedural success for indeterminate strictures or undefined filling defects | Procedure - the average expected duration of the procedure is 1.5 hours | For indeterminate strictures or undefined filling defects cases procedural success is defined as 1) ability to visualize stricture or defect, and 2) ability to provide visual impression of malignancy, and 3) when applicable, ability to obtain SpyBite biopsy adequate for histology |
| Procedural success for biliary stone cases | Procedure - the average expected duration of the procedure is 1.5 hours | For biliary stone cases procedural success is defined as 1) ability to visualize the stone(s), and 2) ability to successfully initiate stone fragmentation, and 3) ability to achieve stone clearance in one or more SpyGlass procedures. |
| Procedural success for other indications | Procedure - the average expected duration of the procedure is 1.5 hours | For other indications procedural success is defined as ability to establish diagnosis and /or complete therapy in the following categories: 1) pre-operative assessment of extent of peri-ampullary and biliary tumors, 2) selective guidewire placement, 3) assessment of unexplained hemobilia, 4) assessment of portal biliopathy, 5) assessment of intraductal biliary ablation therapy, 6) extraction of migrated stents, or 7) other. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of serious adverse events (SAEs) related to the SpyGlass devices and/or the SpyGlass procedure | Procedure from enrollment through the 72 Hour Post Procedure Follow-up Visit | Evaluation of serious adverse events (SAEs) related to the SpyGlass devices and/or the SpyGlass procedure from enrollment through the 72 Hour Post Procedure Follow-up Visit. |
| Impact of SpyGlass procedure on suspected diagnosis based on prior ERCP | Procedure - the average expected duration of the procedure is 1.5 hours | — |
| Evaluation of impact of use of antibiotics on incidence of SAEs related to the device and/or procedure. | Procedure - the average expected duration of the procedure is 1.5 hours | — |
| For patients undergoing SpyBite biopsy: correlation between number of biopsies and conclusive histopathology of SpyBite biopsies. | Procedure to 6 months | Assessment Detail: Endpoint determined for all patients in whom SpyBite biopsy was taken and observed image features were reported. Observed image features include the following categories: None, Growth, Stricture, Hyperplasia, Ulceration, Mass, Dilated tortuous vessels, Papillary or villous projections, Intraductal nodules, Mucus. |
| For patients undergoing stone management: number of SpyGlass procedures needed to reach stone clearance. | Procedure - the average expected duration of the procedure is 1.5 hours | — |
| For patients undergoing stone management: correlation between stone size and ability to reach stone clearance in one SpyGlass session. | Procedure - the average expected duration of the procedure is 1.5 hours | — |
| For patients undergoing stone management: incidence of visualization of stones not suspected during previous ERCP. | Procedure - the average expected duration of the procedure is 1.5 hours | — |
