*Purpose: The study purpose was to evaluate outcomes in vascularized pancreas transplantation (PTx) with enteric exocrine drainage based on technique of venous delivery.
*Methods: We retrospectively analyzed 231 simultaneous pancreas-kidney transplants (SPKTs) performed at our center between 7/2003 – 7/2019 and identified 27 that were performed with systemic venous (iliac vein) and enteric exocrine (systemic-enteric [S-E]) drainage. These 27 patients were compared to 27 case controls with portal venous (superior mesenteric vein) and enteric exocrine (portal-enteric [P-E]) drainage matched for recipient age, gender, race, and date of transplant. All patients received similar immunosuppressive regimens and underwent standardized management protocols. Intention to treat was with P-E drainage.
*Results: The 2 groups were well-matched for numerous donor, preservation, recipient, and immunological characteristics. Indications for S-E drainage were central obesity/thickened mesentery (10), unfavorable vascular anatomy (11), or surgeon preference (6). The S-E drainage group was characterized by slightly more patients ≥ 80 kg (44% S-E versus 26% P-E), with C-peptide positive diabetes (30% S-E versus 18% P-E), and with diabetes onset at >20 years of age (41% S-E versus 26% P-E, all p=NS), suggesting a Type 2 diabetes phenotype. Although the incidence of early pancreas thrombosis (3.7% S-E versus 0% P-E), early relaparotomy rates (30% S-E versus 22% P-E), and mean initial length of hospital stay (11 days S-E versus 8 days P-E) were numerically higher in S-E versus P-E SPKTs, none of these differences were significant. With a mean follow-up of 5 years in both groups, respective one and 3-year patient survival (100% and 96% S-E vs 100% and 100% P-E), kidney graft survival (100% and 96% S-E vs 100% and 89% P-E), and
*Conclusions: The method of venous delivery of insulin following PTx does not appear to influence medium-term outcomes in SPKT with enteric exocrine drainage.
