GI Endoscopy

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

Efficient hemostatic therapy is applied. The Doppler is used to verify that there is no persistent blood flow.
