Specialized Instruments for Complex Colonoscopy and ERCP
Clinical Bottom Line
| Specialized Instrument | Specific Usage | Endoscopic Setting |
|---|---|---|
| Distal Attachment Caps | Depresses mucosal folds; stabilizes tip control. | ESD, difficult right-sided colonoscopy, underwater EMR. |
| Extraction Balloons | Sweeps the biliary tree. | ERCP: Removal of biliary sludge and small choledocholithiasis. |
| Lithotripsy Baskets | Captures and mechanically crushes large stones. | ERCP: Difficult, large, or impacted biliary stones. |
Niche Endoscopic Tooling
While generic snares and biopsy forceps handle the bulk of daily endoscopy volumes, complex procedural success relies heavily on niche instrumentation. Distal attachment caps, originally designed for mucosal resection, are now routinely deployed during complex screening colonoscopies to flatten haustral folds and dramatically improve the Adenoma Detection Rate (ADR) behind blind corners.
Biliary Tooling in ERCP
Within ERCP, the management of choledocholithiasis transitions from simple balloon sweeping to advanced wire-guided lithotripsy baskets. When a stone exceeds the diameter of the biliary sphincterotomy, a mechanical lithotripter basket is deployed to capture the stone and rely on a high-tension cranking mechanism to physically fracture it within the duct prior to extraction.
