Pancreas transplantation using non-suture cuff technique in the neck

Area of Science:

• Surgical innovation in transplantation research
• Rodent models for biomedical research
• Endocrinology and metabolic disease research

Background:

• Pancreas transplantation is crucial for diabetes treatment.
• Traditional rat models face challenges like systemic circulation clamping.
• Developing safer, more reliable transplantation techniques is essential.

Purpose of the Study:

• To establish a successful heterotopic pancreas transplantation model in rats.
• To evaluate a novel non-suture cuff technique for vascular anastomosis.
• To assess the safety and reliability of this technique in a preclinical setting.

Main Methods:

• Heterotopic pancreas transplantation performed in a rat model.
• Utilized a non-suture cuff technique connecting to neck vessels.
• Enlarged portal vein diameter and employed fat clay for anastomosis.
• Avoided systemic circulation clamping during the procedure.

Main Results:

• Achieved a high success rate of 80% (16 out of 20 rats).
• 16 rats survived beyond 30 days post-transplantation.
• Maintained serum glucose levels below 200 mg/dl in surviving rats.

Conclusions:

• The non-suture cuff technique for heterotopic pancreas transplantation in rats is safe and reliable.
• This method offers a superior experimental model by avoiding detrimental systemic circulation clamping.
• Recommended for future research in pancreas transplantation and diabetes models.
