AbstractIntroductionSimultaneous pancreas‐kidney transplantation (SPK) is an option for patients with type 1 diabetes (T1D) and kidney failure but can be associated with a high complication rate. Here we describe our 10‐year experience since the launch of the SPK program.MethodsThis retrospective study included consecutive patients with T1D receiving SPK from March 14, 2010 to March 14, 2020 at Helsinki University Hospital. Portocaval anastomosis (i.e., systemic venous drainage) and enteric exocrine drainage were used. A specific team was trained for both pancreas retrieval and transplantation, postoperative care was standardized to include somatostatin analogues, antimicrobial treatment, and preoperatively initiated chemothrombopropylaxis. During program maturation donor criteria were expanded and logistical processes improved to minimize cold ischemia time. Clinical data were collected from a nationwide transplantation registry and patient records.ResultsA total of 166 SPKs were performed (median 2 per year in the first 3 years, 17.5 per year for the following 4 years, and 23 per year for the past 3 years). Seven patients (4.1%) died with a functioning graft with a median 43 months follow‐up. One‐year pancreas graft survival was 97.0%, 3‐year pancreas graft survival was 96.1% and 5‐year was 96.1%. Mean HbA1c was 36 mmol/mol (SD 5.57) and creatinine was 107 μmol/L (SD 34.69) at 1‐year after transplantation. All kidney grafts were functioning at the end of follow‐up. Complications required re‐laparotomy in 39 (23%) patients, mostly due to a pancreas graft related problem (N = 28). No pancreas or kidney graft failure from thrombosis occurred.ConclusionA planned, step‐wise development of an SPK program offers a safe and effective treatment for patients with T1D and kidney failure.
