Extracorporeal Hypothermic Perfusion Device for Intestinal Graft Preservation to Decrease Ischemic Injury During...

Area of Science:

• Transplantation research
• Organ preservation techniques
• Gastroenterology

Background:

• The small intestine is highly susceptible to ischemia during transplantation.
• Ischemia-reperfusion injury significantly impacts intestinal graft viability.
• A novel device for extracorporeal perfusion was developed to address these challenges.

Purpose of the Study:

• To evaluate the feasibility and efficacy of a new intestinal perfusion unit (IPU) for human intestine preservation.
• To compare the viability of perfused human intestine segments with those preserved using static cold storage.

Main Methods:

• Five human intestines were procured for the study.
• Experimental segments underwent continuous perfusion with cold preservation solution via the IPU for 8 hours.
• Control segments were preserved using static cold storage, and tissue samples were histopathologically graded using the Park/Chiu scoring system.

Main Results:

• Experimental jejunal segments showed a lower Park/Chiu score (2.2) compared to control segments (3.2).
• Ileal segments demonstrated equal scoring between experimental and control groups (1.6).
• Histopathologic evaluation indicated favorable preservation in perfused segments.

Conclusions:

• Extracorporeal intestinal perfusion with the IPU is a feasible technique for preserving human intestine viability.
• The IPU demonstrates potential for improving intestinal graft preservation and reducing ischemia-reperfusion injury.
• These findings support further investigation into expanding the applications of intestinal perfusion in transplantation.
