Mechanical Lithotripter Systems in ERCP: Olympus Type vs Sohendra TTS/OTW

Introduction: Choosing the Right Lithotripsy Approach

Managing large or impacted bile duct stones during ERCP requires reliable lithotripsy support. Mechanical lithotripters like Olympus Type and Sohendra (TTS / OTW) are widely used, but their role differs based on procedural stage and difficulty. In stone extraction procedures, when standard baskets fail to retrieve large stones, mechanical crushing is performed to break them into removable fragments. This step is critical to complete duct clearance safely. Understanding which system to use—and when—helps improve success rates and reduce complications.

Product Role in Clinical Practice

Olympus Type Lithotripter (Mechanical Lithotripsy System)
Advin Health Care’s Olympus Type Lithotripter is designed for planned lithotripsy during ERCP. It works as an integrated system with compatible baskets, allowing controlled crushing of stones under guided conditions. This method is typically used when large stones are identified early and require fragmentation for removal.

Sohendra Lithotripter (TTS / OTW Type)
Advin Health Care’s Sohendra Lithotripter is primarily used as a rescue device. In cases where a retrieval basket becomes impacted with a stone, the lithotripter is used to crush the stone and release the trapped basket.

• TTS (Through-The-Scope): Passed through the endoscope channel
• OTW (Over-The-Wire): Advanced over a guidewire for better access in difficult anatomy

Primary vs Rescue Approach: Understanding the Difference

Olympus Type Lithotripter is used in a planned approach, where the clinician anticipates the need for stone fragmentation. Sohendra Lithotripter is used in unexpected or difficult situations, especially when standard methods fail.

Key distinctions include:

• Olympus Type → Planned stone crushing
• Sohendra → Rescue lithotripsy in basket impaction
• TTS → Standard endoscopic access
• OTW → Better control in complex cases

Quick Comparison Overview

Clinical Preference & Real-World Use

Advin Olympus Type Lithotripter is preferred when dealing with known large stones where fragmentation is expected. It ensures smoother workflow and controlled stone management.

Advin Sohendra Lithotripter is essential in challenging ERCP cases. It acts as a backup solution when baskets get trapped, helping avoid surgical intervention and completing the procedure effectively.

For procurement teams, Advin Health Care offers both primary and rescue lithotripter systems, ensuring complete ERCP preparedness and reducing dependency on external interventions.
