Surgery in transplant patients

From Surgopaedia

Principles

[edit | edit source]
  • Immunosuppression is not a contraindication and good outcomes can still be achieved
  • Contact transplant team before operating
  • Common conditions can present atypically - rely on imaging
  • Don't stop immunosuppression, but medications will need to be adjusted/managed

Pre-op workup

[edit | edit source]
  • Assess graft function
    • Kidney - urine output, ability to concentrate urine
    • Liver - jaundice, pruritis, fluid retention
  • Assess associated diseases
  • Bloods
  • Nutritional assessment
  • Altered anatomy
  • Immunosuppressants
    • Azathioprine can be withheld for two days
    • Mycophenolate can be withheld for 2-3 days or continued, and there is an IV alternative
    • Cyclosporine can be given IV at 1/3 of usual dose
    • Calcineurin inhibitors can be continued
    • Sirolimus/everolimus - if elective, try and change to calcineurin inhibitor to allow wound healing
    • Steroids

Operative principles

[edit | edit source]
  • Careful tissue handling - risk due to immunosuppression
  • Always be careful of altered ureter if present
  • Consider prolonged antibiotics
  • Consider stress dosing steroids

Appendicitis

[edit | edit source]
  • Often appropriate to perform emergency surgery locally then transfer to a transplant list
  • Obviously consult transplant centre up-front
  • Can generally be done laparoscopically
  • Rarely have adhesions due to poor wound healing, so consider other causes
  • Manage as usual

Biliary tree pathology

[edit | edit source]
  • Common, obviously if it is a liver transplant need to transfer

Diverticulitis

[edit | edit source]
  • High rates of complication and mortality
  • Consider elective resection even after one episode
  • No anastomosis in emergency
