Hemostatic powder spray: a new method for managing gastrointestinal bleeding

Area of Science:

• Gastroenterology and Endoscopy
• Medical Device Technology

Background:

• Gastrointestinal bleeding is a significant cause of morbidity and mortality.
• Current endoscopic hemostatic techniques have limitations, including a 5-10% rebleeding risk.
• There is a need for novel, safe, and effective methods for gastrointestinal bleeding management.

Purpose of the Study:

• To evaluate the technical feasibility, clinical efficacy, and safety of hemostatic powder spray (Hemospray) for gastrointestinal bleeding.
• To review existing literature on the use of Hemospray in managing upper and lower gastrointestinal bleeding.

Main Methods:

• Extensive literature search of case reports and case series.
• Analysis of data regarding indications, technique, deployment, success rates, complications, and limitations of Hemospray.
• Inclusion of data from human subjects and porcine models.

Main Results:

• A combined technical and clinical success rate of 88.5% in humans and 81.8% in porcine models.
• Rebleeding occurred in 16.2% of human subjects and 27.3% of porcine models within 72 hours.
• No procedure-related adverse events were reported with Hemospray use.

Conclusions:

• Hemospray demonstrates potential as a safe and effective endoscopic treatment for gastrointestinal bleeding.
• The hemostatic powder spray offers a promising alternative to existing hemostatic modalities.
• Further studies are warranted to confirm the long-term efficacy and safety of Hemospray.
