Kidney, Pancreas & Intestinal Transplantation Mr James Gilbert Consultant Transplant & Vascular Access Surgeon
Figure 2.2. Growth in prevalent patients by treatment modality at the end of each year 1997–2012 • 54,824 adults on dialysis in UK • Represents 108 per million population (pmp) • 6891 new starters in 2012 • Continues to rise year on year
Transplant is a ‘treatment option’ • Ultimate form of RRT • Improves quality and quantity of life • Allows normal diet and fluid intake • Progressive reversal of anaemia & bone disease • All patients with ESRF should be considered • Not necessarily for everyone • There is an alternative (HD, PD, Conservative) • Transplants don’t last forever
Life enhancing or life saving? • Doubles life expectancy (20 years vs. 10 years overall) • Cost of transplant = 1 year dialysis costs!
The insulin-dependent diabetic is: • 25 times more prone to blindness • 17 times more prone to kidney disease • 5 times more often afflicted with gangrene • Twice as often afflicted with heart disease Has a life expectancy 1/3 less than that of the general population
Pancreas Transplantation: • Only treatment that reliably offers type 1 diabetics: • Insulin independence • Normal glucose metabolism • Normal Diet • Ameliorate secondary complications DM • Improved quality and quantity of life • Now associated with improved outcomes • Viewed more enthusiastically rather than sceptically
Any pancreas program should: • Have overall low morbidity & mortality • Eliminate need for insulin and BM monitoring • Eliminate hypoglycaemic events • Create a euglycaemic state with pre and postprandial sugars comparable to non diabetics • Achieve HbA1c levels comparable to those in non diabetics
Best results achieved when: • Have a ‘perfect’ donor • Young, slim DBD Donor • Have a ‘perfect’ recipient • Pre-dialysis and slim • ‘Perfect’ retrieval and short cold ischaemic time • No complications • Ideals rarely possible but must strive for ‘perfection’ due to sensitive nature of the pancreas • Hence fussy pancreas transplant surgeons
Donor considerations • Age: <55 (DBD) <50 (DCD) • Girth < 90cm / BMI < 27 • ‘Good health’ history • Minimal ‘down time’ • Minimal fatty infiltration or fibrosis of parenchyma • Short cold ischaemic time
Surgical options • Simultaneous Pancreas & Kidney (SPK) • Pancreas after Kidney (PAK) • Pancreas Alone (PAT) • (Islets) – Radiological guided infusion into portal system
SPK Transplant Exocrine drainage to proximal SB Portal vein onto IVC Y-Graft onto distal aorta / RCIA Kidney onto left iliac vessels
PAK / PA Transplant • Recent move to bladder drainage (2011) • Consequence of inferior outcomes c/w SPK • 70% 1 yr survival 2010/11 • Use urinary amylase as a measure of function • Higher morbidity for the patient but ? Better graft survival (time will tell)
Common peri-operative problems • Bleeding • Thrombosis • Graft Pancreatitis • Delayed Graft Function • Prolonged ileus / exacerbation gastroparesis • Need for TPN • Sepsis • Peri-pancreatic collections • Pancreatic leaks
Graft Pancreatitis • Appears during the first few days and common • Usually self limiting • Pain and tenderness at the graft site • Associated peri-pancreatic oedema / collection • High drain amylase • Usually result of: • Ischaemic reperfusion injury • More common in marginal organ, DCD & larger recipient • Handling • Infection
Oxford Pancreas Programme Activity & Outcome Data April 2011 – Mar 2013
Transplant Outcomes (1 Year) 3 deaths in first 30 days: 1 with ARDS, 2 Cardiac Arrest.
Mortality Comparison 2 times more likely to die each year on waiting list than in first year after transplant
Intestinal Transplantation - Types Isolated Small Bowel Multivisceral Whole Liver & Small Bowel Modified Multivisceral
Indications Presence of irreversible intestinal failure with Impaired venous access for TPN (reduced to the last two suitable veins for placement of the feeding catheter) Progressive fibrotic liver disease (usually from TPN) Life threatening episodes of catheter related sepsis Broadly two situations that lead to intestinal failure: Short gut syndrome (less than 40 cm in length) Non functioning bowel
Multivisceral Isolated Small Bowel
