简要总结
The purpose of this clinical trial is to verify the safety and effectiveness of autologous islet organoids transplantation after in vitro expansion for the treatment of pancreatogenic diabetes.
详细描述
The purpose of this clinical trial is to verify the safety and effectiveness of autologous islet transplantation after in vitro expansion in the forms of functional islet organoids, for the treatment of pancreatogenic diabetes in participants who have undergone pancreatic resection through a single-center single-arm study. The investigators aim to establish the entire operational process of isolating expanding and transplanting islets from the pancreas removed from the participants and managing postoperative care. The investigators hope to accumulate clinical experience in treating pancreatogenic diabetes with transplanted autologous islet cell clusters expanded in vitro establish standard and regulated medical operations and gather materials for future applications of this treatment method in clinical practice.
