经腹腔镜微囊化猪胰岛异种移植术

目的：探讨腹腔镜技术应用于海藻酸钠－聚赖氨酸－海藻酸钠（APA）微囊包裹猪胰岛小网膜腔内异种移植术的可行性。方法：采用腹腔镜技术对5例6人次I型糖尿病患者进行了APA微囊新生猪胰岛小网膜腔内异种移植治疗，观察患者移植前后空腹血糖、C肽和胰岛素用量变化。结果：全部病例均未出现手术并发症。术后受体C肽较术前升高3－23倍，胰岛素用量减少，基中1例完全停用胰岛素，成为胰岛素不依赖者达31个月。结论：腹腔镜技术用于临床微囊化新生猪胰岛小网膜腔移植术治疗I型糖尿病安全可行。

Xenotransloantation of APA microencapsulated neonatal swine islet cells by laparoscopic procedure

Objective To investigate the feasibility and security of omentum minus cavity xenotransloantation of alginic-polylysine-alginic(APA) microencapsulated neonatal swine islet cells by laparoscopic procedure. Methods 5 patients with IDDM received the xenotransloantation of APA microencapsulated neonatal pig islets in omentum minus cavity by laparoscopic procedure.The patients' general conditions,the change in fast blood glucose level,serum C-peptide and the dose of insulin used were observed before and after the xenotransplantation. Results No complications occurred during operation and after operation.The levels of serum C-peptide increased by 3 to 23 times respectively and the post-operative dose of insulin needed decreased obviously.Insulin independency was achieved in one recipient for up to 31 months. Conclusions Omentum minus cavity xenotransplantation of APA microencapsulated neonatal pig islets for the treatment of IDDM patients by laparoscopic technique is safe and practicable.
