GI Endoscopy
Endoscopic Doppler used to Guide Treatment of Acute Peptic Ulcer Hemorrhage
The VTI Selectable Depth Doppler System is a sound breakthrough in the endoscopic treatment of acute peptic ulcer hemorrhage. By incorporating a probe that can be passed down a 2.8mm endoscope channel, this system identifies blood flow in an ulcer base prior to treatment, as well as allowing for evaluation of persistent blood flow after hemostatic treatment.
Clinical studies (including RCTs) have shown that Doppler guided endoscopic hemostasis of patients with severe upper GI hemorrhage significantly reduced 30-day rates of rebleeding compared with standard, visually guided hemostasis. In addition, cost analysis studies have shown that Doppler guided treatment is more effective and less costly than conventional care.
Endoscopic Procedures
- Management of nonvariceal upper GI bleeding
- Diagnosis of gastric varices
- Guidance of glue injection of gastric varices
- Lower GI applications
Benefits
- Does NOT require EUS equipment or training
- Compact and portable system; easy to use
- Probes can be passed down a 2.8mm or larger channel
- Provides real-time evaluation of vasculature
- Distinguishes arterial and venous flow
- Utilizes disposable Doppler probes which optimize patient safety and probe reliability
- Available for upper GI or lower GI applications
Clinical Studies Demonstrate:
- Use of Doppler probe in nonvariceal upper-gastrointestinal bleeding is less costly and more effective than standard of care.1
- Doppler-guided management of patients with severe upper GI bleeding significantly decreases 30-day rebleeding rates as compared to standard of care.2
- Ulcers that remain Doppler positive immediately after endoscopic therapy are at significantly higher risk for recurrent bleeding.3

Using the Endoscopic Doppler, the endoscopist creates an “acoustic map” of the vsculature prior to therapy.
Efficient hemostatic therapy is applied. The Doppler is used to verify that there is no persistent blood flow.
