TWFC Model Introduction — Interventional EUS & ERCP Training Models

The Models

What you can practice

A growing family of station models covering diagnostic and therapeutic biliopancreatic endoscopy.

🩺

ERCP

Cannulation, stone & stricture management, sphincterotomy and stenting.

🎯

EUS — FNA/B

Fine-needle aspiration & biopsy: targeting, puncture angle and sampling.

💧

EUS — Pseudocyst

Cyst-gastrostomy drainage with lumen-apposing stent placement.

🫙

EUS — GB

Gallbladder drainage puncture, tract creation and stenting.

🔗

EUS — CDS

Choledochoduodenostomy: transduodenal biliary access and stent.

🌿

EUS — HGS

Hepaticogastrostomy: puncture at the bifurcation, guidewire and stent.

EUS — Coil

Coil embolization station — in development for the next release.

The Lesson

Six things every station teaches

Anatomy — Puncture Area

Recognise the target and safe window before the needle goes in.

Scope & Guidewire Manipulation

Coordinated scope position and wire control under EUS.

Step Approach

A repeatable sequence for each procedure, start to finish.

Troubleshooting & Equipment Modification

Adapt when the standard step does not go to plan.

Stent Mis-Deployment

Recognise, rescue and correct a poorly deployed stent.

Short Stent

Handle length mismatch and its consequences on the model.

Interventional EUS

Create Fistula Tract + Stenting

The core therapeutic skill on the platform: under EUS guidance, puncture the target duct, advance the guidewire, create the fistula tract, and deploy a stent — all while keeping the critical structures in view.

Tips & Tricks for the Model

Small details that decide success

General puncture

applies to every station

Needle insertion must be free — if it isn't, pull the scope back first. Be careful.
Keep the scope parallel to the puncture site.
More flex → the lesion moves further away vs. breaking the model — balance it.
Turn the knob slowly — over-torque means perforation in real life.
Always check the cautery setting before every puncture.

CDS

Choledochoduodenostomy

EUS-CDS

Tip the scope up before puncture.
Position the stent so it does not occlude the cystic-duct junction.

HGS

Hepaticogastrostomy

EUS-HGS

Puncture at the bifurcation.
Try to keep the stent from blocking Seg. II (if possible) — but weigh this against stent migration.

Gastrojejunostomy

EUS-GJ

The jejunal wall must sit closed against the stomach wall.
Puncture slowly.
