Pancreas Transplantation at MCA
Pancreas Transplants at MCA by type of transplant
Type of Surgical Procedure
MCH Patient/Graft Survival for KP Txs (Kaplan-Meier)
MCH Patient/Graft Survival for PAK & PTA (Kaplan-Meier)
Immunosuppression Thymoglobulin Prograf MMF Long-term steroids Campath Rapid steroid taper
Acute Rejection during the first year Kidney-Pancreas : 17% Solitary Pancreas: 32%
Kidney-Pancreas : Steroid Avoidance 37 patients Patient survival 100% Graft Survival Kidney 97% Pancreas 95% Acute Rejection 11%
Pancreas Experience with HTK (n=100) Mean CIT = 9.6hrs (4hrs – 22.9hrs) Less than 12hrs – 77% 12 to 15.9hrs – 18% Greater than 16hrs – 5% No cases of graft pancreatitis or vascular thrombosis due to preservation
Historical Total Transplant Volumes 2001 to present
Conclusions Strong clinical academic solid organ transplant practice with complete conversion from UW to Custodial HTK in 2003 without any negative effect Improved outcomes using Custodial for Living Donor Liver Transplantation Recommendation for HTK for DCD donors to improve outcomes
